Code of practice for legal admissibility and evidential weight of information stored electronically

- by

Will the law admit your evidence?

Many AGS Members prepare reports which may have evidential weight. They may be backed by digital photographs or other electronically stored information. What measures need to be taken to ensure that these documents will be legally admissible should the need arise? a new document has been published by BSI in recognition of the large number of implementations of electronic information management systems, and of the continuing uncertainty about the legal acceptability of information stored on these systems. It provides good practice guidance for the electronic creation, storage and retrieval of information and practical advice and examples to assist you in increasing the evidential weight of your electronically stored information.

On a broader front, information is an asset and companies are increasingly committing key records and documents to electronic media. The application of electronic information management systems is changing the way in which many aspects of business and organizational life are operated, and is creating an electronic legacy for their successors.

This publication provides a framework and guidelines that identify key areas of good practice for the implementation and operation of electronic storage systems, whether or not any information held therein is ever required as evidence in event of a dispute. As such, compliance with this Code should be regarded as a demonstration of responsible business management.

Notes on Asbestos liability and Insurance Issues

- by

From ABI Seminar on the availability of insurance for asbestos related risks and the impact of the new asbestos regulations

The ABI provided a series of well qualified and experienced speakers to address this topic from a selection of viewpoints. The delegates fortunate enough to attend came from a wide range of professions including consulting engineers, construction contractors, insurance brokers, insurance underwriters, research bodies, trade associations, government agencies, solicitors, surveyors asbestos removal contractors, regulators and analytical laboratories.

The scene was set by Bill MacDonald of the HSE who outlined the historic and future problems associated with asbestos. Currently asbestos related deaths run to around 3500 in the UK and are expected to rise until 2011, when the effects of improved working conditions and asbestos prohibitions will begin to kick in. However the nature of how the effects will diminish cannot be predicted. The new Regulations (Control of Asbestos at Work Regulations, 2002) react to conditions now, which indicate the greatest risk is due to occupational exposure within buildings, especially for workmen involved in internal and maintenance trades. The Regulations only apply to non-domestic properties

The Regulations impose a ‘Duty to Manage’ asbestos risk by assessing existing conditions, recording the findings, preparing action and management plans and advising/cooperating with others with respect to asbestos risks. The ‘Duty Holder’ is the person with contractual responsibility for maintenance repair of the building and may be the owner, occupier, managing agent, but in all cases will be ‘in control’ of the building.

The HSE advice is to: Adopt precautionary approach -NOW Carry out condition surveys – SOON Plan compliance strategy -START NOW These should take into account that compliance is a rolling process and that expenditure should be proportional to the level of risk. The HSE website has relevant information and guidance www.hse.gov.uk/campaigns/asbestos. HSE Information line 08701 545500

The background to why asbestos has become a major insurance issues was provided by Helen Hatchek of Royal Sun Alliance. The asbestos insurance market is global and it is the influence of the US experience, which is driving the market at present. Public liability claims are currently at $200 Billion and rising (equivalent to the twin towers x2), with average claims T $6-6.5Million. Under US law, most claims fall under public/product liability as employers cannot be sued. As such all industries in the supply chain are potentially affected. Class actions are normal, and due to joint and several liability, claimants target the defendant with most ‘funds available’. There has also been successful ‘unimpaired’ health claims, where compensation has been awarded for ‘worry’/ stress and cost of on-going health screening.

Although, all claims to date are related to Employers liability and judges currently set awards which is less emotive that those set by a jury, the UK market is showing signs of following the US. This has led to concern that additional claims may arise through public liability due to subrogation from Employers liability claims, ‘shake-down’, neighbours, product liability and corporate responsibility. The market has reacted by re-insurers excluding asbestos in its entirety, insurers have introduced exclusion and limitation wordings and in a market of declining appetite, some insurers have removed all cover, leaving limited availability.

Matt Farman of Howden Insurance Brokers discussed the developments in the PI market. They offer a bespoke scheme for UKAS accredited laboratories.

The current insurance market is hard with high premiums and restricted cover, but it should be borne in mind that insurers are commercial bodies and do not need to be exposed to high risks. Asbestos exclusions appeared in 2003, driven by the re-insurance market in light of huge asbestos related claims and losses suffered by the Employers Liability and Public Liability insurers worldwide, with an even more unsure future. In 2003 RICS voiced concerns about the lack of asbestos cover and set up a working party .to find a solution. This involved the asbestos cover being excluded by the re-insurers but with a ‘write-back’ clause added by the insurers reinstating some limited and very restricted cover. Typically this is around £250,000 on aggregate, ie the re-insurance limit. It is generally only available at the discretion of the insurers. The cover is limited to claims arising from negligence for rectification, remediation and loss in value, but excludes consequential loss and any form of bodily injury.

In the same way that ‘Pollution and contamination’ cover was originally withdrawn and the market softened so that it is now currently available on a restricted and ‘aggregated’ basis, asbestos cover may follow the same path, depending on how the re-insurance market responds to future events and information. However, in order to achieve the best available cover currently, professionals, their governing bodies and trade associations need to be pro-active to demonstrate sensible levels of risk assessment and management. This may include only offering suitable terms and conditions to clients, with restricted cover based on a multiple of fees and excluding consequential loss, using only experienced and qualified staff.

Insurance from a buyers perspective was discussed by Kevin Goodwin of AIRMIC Contractors Group. He noted that insurance was generally not available, but due to time lags over renewal dates, some contractors still had cover whilst others were unable to provide on-going cover, except where a ‘write-back’ clause could be negotiated. There is also a wide variation in the exclusion clauses seen with no apparent consistency.

In France and Germany, the problem is being addressed by government funding being provided to cover personal injury asbestos claims, but the UK government has not shown any sign of adopting a similar approach. Indeed, tightened regulations, which generate more asbestos ‘activity’, have coincided with the insurers pulling out of that market.

Liabilities with respect to asbestos for many can arise from a variety of sources. Typically those most affected are likely to be employers/property owners, consultants, contractors (licensed or not) and facilities manager. Insurance policies in all areas have responded to the asbestos risk.

Employers Liability:   may exclude asbestos cover, but cover may be found based on demonstrable risk management, but unlikely for asbestos contractors.

Public Liability: possible total exclusions, of which there are numerous versions, with possible ‘write-backs’.

Professional Indemnity: check wording of exclusions, PI liability will probably be covered but all health hazard risk excluded.

Director and Officer Insurance: -exclusions possible. Beware of clauses such as ‘Board’s failure to act under Regulations.’failure to maintain insurance’ (which may not be available!),

Beware of ‘silence’ within any policy. This should be queried.

In all cases, to demonstrate risk management to be able to obtain the best terms available, compliance with Regulations 9,10 and 15 of the CAWR 2002 will be essential ie employer ensuring adequate training of staff, and limiting potential exposure to minimum levels. However, where insurance is difficult and costly to obtain, there is potential for growth of the ‘black market’ contractors, ie with no insurance.

Roger Flaxman explained how RICS, as a professional body representing members dealing with asbestos, are approaching the problem associated with lack of available cover for its membership. Generally chartered surveyors face a high risk/reward ratio and are in competition with lesser qualified /experienced ‘inspectors’. P402 is seen as a low technical standard and RICS members believe that they would be expected to provide a higher standard. If the surveyors work to a higher standard and hence risks are reduced, proof of this should make obtaining affordable insurance a greater possibility. To this end RICS have introduced the National Individual Asbestos Certification Scheme (NIACS). This requires proof of suitable professional qualifications as a foundation to membership, supported by increased training requirements, and individuals (not forms) being examined and audited on technical capability related to both asbestos and building construction. It is further proposed that the NIAS qualification will be linked to UKAS accreditation.

Conclusions

The introduction of the CAWR Regs 2002 has coincided with re-insurers withdrawing from the asbestos insurance markets due to a huge potential for future asbestos related claims worldwide. This has resulted in insurance policies all excluding asbestos. The only way cover can be obtained is under ‘write back’ clauses where insurers provide very restricted and limited cover aggregated within the limit of the re-insurance requirements. This cover does not include any bodily injury claims. This insurance is also only available at the discretion of the insurers , typically to established clients who have a good no-claims record and demonstrate an adequate level of risk assessment and management with respect to asbestos.

The market is currently uncertain and therefore hard. Once the true level of risk becomes clearer and the insurance purchasers recognise that there is an onus on them to educate the insurers and re-insurers of the actual asbestos related activities and associated risks for which cover is required, it may be possible to purchase more bespoke cover. This is the aim of qualifications such NIACS as proposed by the RICS.

However it is unlikely that cover for ‘bodily injury’ will ever become available and there is a case for governmental provision to cover some of the future uninsurable compensation claims arising from asbestos issues.

Cover systems for land regeneration

- by

The report prepared by RSK ENSR on behalf of the AGS in partnership with the BRE is now available.

Cover systems are used to reduce the hazard to human health and provide a medium for plant growth by providing a layer of clean material over contaminated ground. However, their design has often been ad hoc, with no overall consistency of approach in the specification of thickness, the quality of material that is acceptable, or the degree of protection for which they are intended. Designs which are too thick result in unnecessary cost, but those that are inadequate may not provide sufficient protection. The Guide will facilitate the design of a cost effective and satisfactory system.

The Guide is accompanied by a CD-ROM will includes a calculation tool to determine the required thickness and a PowerPoint presentation to help the user understand the key aspects of cover systems.

CSCS – What you need to know

- by

The CSCS Scheme was set up in 1995 and there are currently more than 600,000 card holders covering more than 170 occupations. The aim of the scheme is to reduce accidents, improve quality and to drive out the cowboy element. After a relatively slow start, the initiative was given a huge boost by the decision of the Major Contractors Group (MCG) to work towards a 100% carded workforce by 1 January 2004. Other large contractors and many clients have adopted similar policies. Although there is no legal requirement to carry a CSCS card – and the scheme is voluntary – anyone going on site either on a regular basis, or as a visitor, may find their entry is barred (or their movements restricted) if they cannot show one.

The nuts and bolts of the CSCS Scheme

To obtain a card all candidates must demonstrate competence in health and safety on site, and most have to demonstrate competence in their trade or profession.

1.    Safety: The safety requirement is normally fulfilled via a multiple choice touch screen test taken at the DVLC test centres. The test must be re-taken when the card is renewed.

(Note: Although this is sufficient for CSCS purposes, it does not absolve the employer from providing adequate safety training and employers should continue to provide safety awareness and other safety training (eg tool box talks) as appropriate.)

2.   Competence: CSCS cards are linked to National Vocational Qualifications and Scottish Vocational Qualifications and CSCS considers these are the benchmark for demonstrating competence. In general, if no NVQ/SVQ exists – there is no card. This applies equally to site operatives and to management grades up to NVQ Level 5 (ie up to and beyond degree level).

Routes to demonstrating competence

Trainee: A Trainee Card (Craft and Operative) is available for those registered for an NVQ/SVQ Level 2 or 3 but who have not yet obtained the qualification. It expires after 3 years. A Trainee Card (Technical, Supervisory & Management) shows that the holder is registered with a further/high education college for a national recognised construction relation qualification, or has completed such a course within the last 2 years. The card expires after 3 years and can be renewed for a further 3.

NVQ/SVQ: A skilled card is issued to NVQ/SVQ achievers whose occupation is available for CSCS. Cards are valid for 5 years.

Industry Accreditation (Grandfather Rights): This route is only open for some occupations (eg the BDA has decided that it should not be open to drillers) and is only available for a 2 year period after the CSCS Scheme is opened to a particular occupation. The application form must include a recommendation from the present or previous employer. The card is valid for 5 years and can be renewed by getting an employer’s recommendation.

BE AWARE that the industry accreditation period for Civil & Structural Engineering Designer has already ended and those for Civil Engineering Site Manager (and Supervisor), and Construction Plant and Equipment Manager (and Supervisor) end on 17 June 2004.

Experienced Worker: For people who do not have an NVQ/SVQ where there is no industry accreditation or where the industry accreditation period has ended . An employer declaration is needed (as for Industry Accreditation) and the holder must be registered for an NVQ/SVQ at level 2 or 3. The card expires after 3 years – it cannot be renewed.

Construction Site Operative Card: Acts as an identification card (ie not a competence card) for those who have achieved NVQ/SVQ Level 1 in a number of occupations including land drilling, specialist plant machinery operations, and underpinning operations. It can also be achieved by industry accreditation. It lasts for 5 years.

When no CSCS Card exists

When no card exists, a Regular Visitor card can be obtained. This requires the health and safety test only. They are best used with a ‘letter of non-availability’ which will be issued by CSCS on request to confirm that no card exists for a particular occupation.

This should not be confused with the Occasional Visitor card which will be issued at the site gate and carries no requirement for a health and safety test. They are issued under contractors’ own site rules and are not an option for someone needing to work on site.

Professionals

The link between CSCS and NVQ/SVQ also applies to professionals. There are 33 occupations for which Technician, Supervisor and Manager level cards are available. These include: Building Site Supervisor; Contracts Manager; Civil Engineering Site Supervisor; Civil Engineering Site Manager; Construction Plant and Equipment Supervisor; Construction Plant and Equipment Manager; Civil and Structural Engineering Designer; Estimator (Construction); Estimating Assistant (Construction); Health and Safety Officer; Health and Safety Manager; Environmental Manager (Construction); Quality Manager (Construction); Laboratory Technician.

A CIC/CSCS Working Group has been engaged in pilot projects to map equivalence of Professional Membership of some institutions and the relevant NVQ/SVQ standards. Once approved, this will give new and existing Chartered Members of that occupation a route for obtaining a CSCS card. It will require two authorisations – one from the employer and one from the professional institution – to confirm that the applicant has met the professional knowledge requirements, has a minimum of 1 year site experience, and is up to date with CDP requirements. The ICE is one of the pilot institutions (for Construction Site Manager and Construction Site Supervisors ) and this route became available in April 2004 (for these occupations only – other occupations still have to be mapped.)

Professionals who are not Chartered will not be able to use this route and will only be able to obtain cards via the normal NVQ/SVQ routes (or industry accreditation routes while they are open).

Laboratory Assistants and Technicians

Two new NVQs/SVQs for Laboratory Assistants (Level 2) and Laboratory Technicians (Level 3) have recently been introduced and CSCS cards are now available for these occupations. There is some debate about their applicability to site investigation staff – but some companies may decide that they are an acceptable route. The industry accreditation period is already running and will end on 31 August 2005. Those considering the issue should remember that after this date the only way to obtain the card will be by obtaining the NVQ/SVQ.

Those wishing to apply to CSCS for a non-availability letter to use in conjunction with a Regular Visitor Card might need to argue that the NVQ/SVQ is too general and too broad for the purposes of site investigation. To avoid confusion with the Laboratory Assistant CSCS card, the term Geo-technician (site sampling and testing) might usefully be used.

Drillers

Drillers with an NVQ/SVQ can obtain a card through the usual routes. Those without the qualification will need an Experienced Worker Card while preparing for the NVQ/SVQ.

Conclusion

It is increasingly likely that clients and contractors will expect everyone coming to site to hold a CSCS card. Non card holders may find it difficult, or even impossible to enter the site and may find that site rules require them to be accompanied at all times.

The options appear to be:

  • obtain a card via Industry Accreditation if this is still open for the relevant occupation.

  • obtain a Construction Site Manager or Construction Site Supervisor Card through the Professional Institution route – where the holder is a Member of the ICE (or CIOB) and the occupation is appropriate

  • obtain cards through the NVQ/SVQ routes (using the Trainee or Experienced Worker cards as interim measures while the NVQ/SVQ is being obtained).

  • obtain a Regular Visitor Card and a letter of non-availability from CSCS for those occupations where no suitable card exists

Letter to the Editor

Dear AGS,

Are AGS Members aware of the potential impact Japanese Knotweed (JKW) may have on the development of sites?

If this is not identified when carrying out walk over surveys and ground investigations, the additional cost to the client of clearing the plant from site and the possibility that the ‘Ground Investigation Specialist’ could be blamed for not identifying it in the first place as a potential ‘contaminant’, could result in significant potential liabilities, e.g. A site in the Midlands is currently clearing JKW off site at a cost of over £250,000, as an extra over cost!

The AGS and current British Standards for ground investigation (reporting guidelines) do not appear to specifically cover such potential ‘contaminants’. Should we not be providing advice to both Geotechnical/ Geo- Environmental specialists/ Clients etc in how to identify these invasive plants or at least provide them with guidance as to what specialists should be appointed to identify and deal with such problems? Is this part of our role? What do members think? The EA currently provide guidance notes on their web site www.environment-agency.gov.uk.

In addition the implications of a ground investigation contractor spreading the JKW by vehicle wheels/tracks, samples etc could again be costly. Whilst this weed is widely distributed in Cornwall and Wales, its encroachment into other parts of the UK is rapid.

Any comments or discussion back would be appreciated.
Chris Eaton, Geotechnical Developments (UK) Ltd

A Knotty Problem

Japanese Knotweed is an invasive perennial that can hinder the growth of many native species of plant. It can grow to around 3m high and expands rapidly once it takes hold of a site.

Japanese Knotweed was introduced to the UK during the 19th century as an ornamental plant and can be spread easily from the movement of contaminated soil. The plant is characterised by thick canes with red shoots and bears white flowers. It is notoriously robust and can survive being cut back due to an extensive underground root system.

The Wildlife & Countryside Act of 1981 makes it an offence to spread Japanese Knotweed and any excavated soil that is taken off site must be disposed of at a licensed landfill site.

The Environment Agency website: www.environment-agency.gov.uk contains very useful information about knotweed, how to deal with it, and what precautions need to be taken if it is encountered on site

What Is Finalling?

- by

In future the NHBC will adopt a consistent approach to determining what will and what will not prevent the necessary confirmation that a warranty is in place. In order to facilitate this, any outstanding information, defective design or non-compliance with standards on site must be classified as either RED (prevents warranty) or GREEN (will not prevent warranty) by applying the following sequential logic test:

Will the outstanding issue result in:-

1. A risk to health and safety?
2. A claim against the warranty?
3. Significant disruption to the occupier (in order to rectify the issue)?

If the answer to any of the above questions is yes then the item will be classified as RED and confirmation that a full warranty will be in place will be withheld until the relevant issue is resolved. If the answer to the three standard questions is no then the item will be classified GREEN and confirmation would be provided. It remains the builder’s responsibility to address any outstanding Green issues.

In relation to design issues, inadequate or unsatisfactory information is generally the reason preventing a warranty being in place. Hazards where information will normally be requested by NHBC Engineering include:-

High water table, Made Ground, Mining or other Cavities, Multiple Hazard, Peat, Soft Ground, Steep Slopes (more than 1 in 10), Sulphates, Landfill gas and Peat, Contaminated Land other than Landfill Gas.

Example:  
Geotechnical site investigation report, gas test results and proposals for gas membranes received from a builder for a site with known made ground, past shallow mining and within 250m of a landfill site.

Mining report and foundation proposals not received, therefore fails the logic test and hence would be classified as RED until such information is received and approved.

The CML initiative – how does it affect geo-specialists?

- by

In order to prevent homes being sold and occupied before completion, the Council of Mortgage Lenders (CML) initiative was implemented in April 2003 and has wide ranging implications for anyone involved in property transactions involving brownfield sites, and in particular house builders. Before providing a mortgage on a property, funders now require confirmation by solicitors and licensed conveyors acting on behalf of purchasers, that a new property has been signed off or ‘finalled’ (see below) and has a full warranty in place. This is often an NHBC warranty or similar from another warranty provider.

Prior to April 2003, the standard approach to brownfield redevelopment was to remediate the site with development progressing behind the remediation works as sections of the site are completed. It is usual to carry out appropriate validation testing by a third party, typically a geo-environmental consultant, to demonstrate compliance with outstanding planning conditions relating to contamination. On completion of the whole site, the planning authority and its statutory consultees, including the Environment Agency, would then review the validation data and indicate their acceptance of the work as complying with the relevant planning conditions. In addition the consultant responsible for the validation process may also have been required to complete an NHBC Form of Validation, or similar, to enable the developer to obtain a warranty for the property. Therefore, on medium size and large developments, many of the properties would be completed and occupied before the site warranty was signed off. This will no longer be possible.

In order to prevent developments becoming unmortgageable, remediation designers need to take a staged approach to both remediation works and validation, so that sites can be completed in sections. Each section is then signed off individually on completion. However, this approach has to be agreed in advance with the Regulators so that the implications of phasing on both completed areas and on-going remediation works can be considered.

It is suggested that phasing is introduced as a concept in any remediation statements and mirrored in planning applications, to avoid any future confusion as to how the site is to be redeveloped and released for sale. This may have been implied previously, but must now be clearly identified in development and remediation proposals. This places an onus on developers to have well developed plans before planning submission, where possible, so that changes to proposed phasing are minimised, or to ensure that proposals are sufficiently flexible to incorporate future changes, without compromising previously ‘approved’ phasing and remediation methodologies.

Similarly, environmental consultants acting on behalf of developers should include reference to validation also being completed in phases. In this case, validation documents may be structured such that they can be issued in sections relating to each individual phase. For large projects the validation report may be a series of volumes or a ‘log book’ style document with several addenda.

By taking this approach, which in reality only represents a minor but potentially critical modification of previous protocols, the planning authority and statutory consulates will be accepting the premise of staged development and validation and should be well placed to be able to sign off planning conditions piecemeal. As a result, delays to ‘finalling’ and the all-important sale should be prevented.

The Extension of MCERTS to Chemical Testing Of Soils – An Update

- by

In January 2003, issue number 45 of the AGS Newsletter contained an article by Bruno Guillaume, of Arup Geotechnics, who outlined the MCERTS performance standard for the chemical testing of soils. The following is an update, and a view from an analytical chemist`s perspective.

On the Environment Agency website reference has been made to the fact that the Agency is aware that it will take time for laboratories to gain approval through the appropriate accreditation process. An eighteen month period, starting from March 2003, has been given for laboratories to bring their soil testing methods up to the MCERTS standard.

During this period laboratories reporting data to the Agency have as a minimum to be accredited to the ISO 17025 standard for the soil test methods. It is also recommended that tests should have a brief method description together with estimates of bias and precision. From September 2004 only data from laboratories that have been accredited to ISO 17025 for MCERTS will be accepted.

Since the last article in the newsletter, Version 2 of the MCERTS standard has been published, and this was available from February 2003. The standard highlights particularly important areas, namely contract review, bias and precision targets, quality control( both internal and external), method validation, and uncertainty of measurement. Important differences from the first version are the exclusion of expected limits of detection for methods, and the inclusion of an improved protocol for validation.

The issues can be confusing but the standard simply aims to establish a level playing field in a competitive market, based on the Agency`s requirements, and to set a minimum acceptable performance. In short the data received by the laboratory`s customers must be accurate, reliable and comparable.

The analysis of soil is complex in terms of the chemistry involved. It aims to determine both macro and trace components in a matrix that is, quite often, dirty in both a physical and chemical context. There is a need to analyse for trace organic and metallic contaminants in soils that contain large quantities of other industrial materials, such as oil or tar, in a background that also contains high concentrations of naturally occurring, or artificially polluted, inorganic compounds.

We all use “parts per million” as routine terminology, but the significance is commonly ignored. 1 part per million is more easily visualised as 1 grain of salt in a swimming pool. When we talk of the concentrations of polynuclear aromatic hydrocarbons (PAH), an important environmental parameter, we often refer to micrograms per kilogram, which is three orders of magnitude lower.

The contaminated land testing industry has grown very quickly, and methodologies have been borrowed from other more well established areas of analytical chemistry, such as food or potable water. The only industry standard for analysis of soils in the UK are the robust and technically sound ” British Gas Methods “, but even these were not designed to tackle the lower end of detection, and do not take advantage of some of the more modern developments in analytical chemistry.

MCERTS effectively defines a standard for the performance of analytical methods, and includes the requirements of ISO 17025 in terms of certification of instrument performance, approved competency of personnel and the accreditation of laboratory procedures and organisation. It means that it is no longer sufficient that the laboratories follow a rigorous UKAS quality system in line with the international standard, but that the methodologies must also be demonstrated as fit for purpose.

The Environment Agency has not, in its standard, adopted the principle of prescriptive methods, as has been the example in the USA, through the so-called EPA procedures. This approach can commit the industry to inappropriate analytical techniques, a long time in their reform once committed to paper, and takes away the flexibility of developing new improvements for the industry as a whole.

It cannot be relied upon that environmental specialists, requiring the services of an analytical laboratory, will have the depth of technical to knowledge to understand the concepts of analytical bias or precision. MCERTS is designed to take away the need for such expertise.

Another variable that stops a customer from being able to compare “apples with apples” is the limit of detection (LOD) quoted. This can vary widely depending on how the laboratory defines it. A sound statistical principle is to use three times the standard deviation associated with a blank, or a sample with a very low concentration of the determinand of interest. This is all carried out interspersed with other standards and samples over eleven separate days. Other lesser definitions than this one seem to describe a “better” LOD, but mislead the customer into thinking they are getting an improved service, and can give false positive concentrations on soils where none of the contaminant actually exists.

All of these concerns are addressed by the MCERTS standard. Precision and bias must be of an acceptable standard, as must LOD. “Recoveries”, namely what happens when a soil is spiked with known amounts of the material of interest and is reanalysed, are examined in the standard to ensure acceptable performance. The validation must be carried out on three completely different soil types with two spiking levels, and include the use of certified reference materials wherever possible. Detailed methodologies, together with a prescribed uncertainty of measurement must also be given.

The Contract Review is the point at which the client`s needs must be understood, and the point at which the laboratory must document them. What does ” Total PAH” mean, or “Total TPH”, and what does the client consider to be the critical level of interest? This is an area quite often poorly addressed, and to which the standard lends some priority.

The laboratory`s quality control also comes under close scrutiny. At least 5% of the resources allocated to a test must be used to ensure validation. In addition the laboratory must participate in as many of the acknowledged external proficiency tests as is appropriate, such as Contest, Aquacheck, and the SPH test scheme. The results of these must be readily available for inspection by the client.

It is generally recognised amongst the community of analytical laboratories that there is a real challenge in order to be able to comply with the new version. The standards relating to bias and precision and, in particular, the guideline that “the limit of detection usually regarded as being fit for purpose is 10% of the concentration regarded as the critical level of interest” are extremely demanding. There are some method improvements required within the industry before these levels of performance can be achieved. Most laboratories, however, will feel a relief that any ambiguity is now removed, so that everyone can compete to provide a well defined product, and be able to market its expertise without confusion.

Whilst addressing the vagaries of analytical results the Environment Agency has also acknowledged the uncertainty associated with other areas, and is considering certification schemes to address field aspects, including sampling. Other subjects, for example the suitability of leachability tests, toxicity assessments and the bioavailability of metals need to be topics for guidance by the regulator.

PPC Site Reports – Change in EA Policy

- by

The Environment Agency issued a new policy and guidance on protection of land quality and preparation of site reports under the Integrated Pollution Prevention & Control (IPPC) regime in August 2003 (www.environment-agency.gov.uk/business) The aim of the changes is to place more emphasis on pollution prevention measures within the PPC permit rather than site investigation at the time of application. It also hoped that the change will speed up processing of permit applications by the EA.

The site report accompanying the permit application (now referred to as the Application Site Report) should normally comprise the results of a desk study and site reconnaissance only. This is similar to a Phase 1a site report in the EA’s earlier terminology. Completion of intrusive investigations at this stage is NOT required except in special cases, e.g. there is insufficient data on site geology to develop the site conceptual model.

There is also now a requirement for operators to prepare a Site Protection and Monitoring Programme (SPMP) detailing how pollution of land will be prevented during the life of the installation. This has to be submitted to the EA within 2 months of the permit being issued.

Intrusive investigations to obtain ‘reference data’ (i.e. a Phase 1b or 2 assessment) are only required for zones of the site where there is ‘a reasonable possibility of future pollution of the land’ from installation activities. The guidance states that such investigations will always be required for sites with bulk storage of liquid chemicals, inadequate preventative measures or a history of pollution incidents unless it can be shown that there is little likelihood of future pollution occurring. The investigations will form part of the SPMP and where required have to be submitted to the EA within 6 months of the permit being issued.

The EA has also issued templates for the Application Site Report, design and reporting of a Site Protection & Monitoring Programme.

These changes apply to all sites in England and Wales where PPC permits have yet to be issued. Policy and guidance in Scotland and Northern Ireland currently remain unchanged. There are clearly implications for AGS members to ensure that appropriate advice is being provided to site operators applying for permits and that the most up-to-date guidance is being used.

AGS Response to Nigel Griffiths, MP

- by

On his appointment as Minister for Construction, Nigel Griffiths wrote to all trade associations and professional bodies and invited them to submit a concise briefing note on the issues which Members feel are vital to making Britain world leaders in construction. He indicated that he expected the note to raise our main concerns.

After discussion in the Working Group and the Executive Committee, the following response was sent on behalf of the AGS:

Making Britain World Leaders in Construction

The Association of Geotechnical and Geoenvironmental Specialists (AGS) is a trade association representing almost 100 companies who are specialists in ground engineering. Activities range from geotechnical engineering, ground investigation, and the design of foundations, to the geotechnical and chemical analysis of soil, rock and water and the identification, assessment and remediation of contaminated land.

In responding to the invitation from Nigel Griffiths MP for a concise briefing note, we have concentrated on issues on which our Members specialise and which are within the field of Government influence.

Additionally, the AGS as a Member of the Ground Forum, fully supports the comments made by Ground Forum, particularly in respect of, i) the need for greater funding of post graduate courses in geotechnical engineering and engineering geology; and ii) the need for clarity (possibly via a register) in defining areas of engineering expertise in order that clients can identify specialists with appropriate qualifications and experience for their projects.

1. Inadequate Ground Investigation 

The amount spent on investigation of the ground prior to construction is typically 1% to 5% of the whole project value (usually the lower end of this range). The cost of claims and additional expenses due to unexpected ground conditions (i.e. unexpected because the site investigation was not adequate) can be as high as 50% of the total cost overrun on the project. Furthermore, some (generally smaller) developments do not have any ground investigation at all. We believe very strongly, that an adequate ground investigation should be a requirement of the planning process. We understand that consideration is being given to harmonising building and planning regulations. This therefore presents an ideal opportunity to introduce such a requirement. We therefore propose that the Minister actively supports and promotes the introduction of such a requirement into the harmonised regime.

2. Insurance 

The current difficulties in the availability and cost of Employers Liability and Public Liability insurance have affected AGS Members, as other businesses. However, the major concern has been the soaring cost of Professional Indemnity insurance. This is compounded by the continuing trend for clients (including public sector clients) to require higher and higher levels of insurance cover with high/ unlimited limits of liability, often totally disproportionate to the value of the fees involved. This is particularly the case in regard to work involving contaminated land. It is a common misconception in many client organisations that a consultant’s Professional Indemnity policy is there to cover any loss incurred by the client, however such a loss occurs. This is of course, not the case. A consultant’s Professional Indemnity in there to protect the consultant in the event of a successful claim of negligence. All consultants in the AGS have signed up to our own Code of Conduct which is designed to ensure the potential for negligent act or omission is minimised. In addition, most companies have their own Quality Assurance system (many accredited through the British Standards Institute to relevant international standards, e.g. ISO14001). It is also a fact that to date the number of successful claims specific to our industry is very low.

It is therefore unfairly onerous on the industry for clients to require levels of Professional Indemnity cover and limitations of liability which are often out of all proportion to the fee charged for the services offered by our members (e.g. a liability level of £5m is commonly required for a project with a consultancy fee of less than £2,000). Such a requirement is particularly disadvantageous to small companies who are simply unable to obtain such cover, and are therefore excluded from contracts even when they have appropriate expertise and/ or relevant local knowledge.

Government and other public sector clients could helpfully demonstrate best practice in this respect by entering into such contracts with appropriate requirements for insurance (both level of cover and limit of liability) which reflect inter alia the fee for the project.

3. Onerous terms in Regional Development Agencies (RDAs) contracts

Members work for RDAs in connection with the assessment and remediation of contaminated land. The standard RDA contract terms require the consultant / contractor to provide a collateral warranty with unlimited liability for anyone using the site in the future, and to ensure that the site is ‘fit for purpose’ This is unreasonable on two counts:-

i) Neither unlimited indemnity nor ‘fitness for purpose’ can be covered by insurance . In the event of a successful claim therefore, the only recourse for the company will be to close down and surrender all their assets. This is a totally unacceptable way to enter into a contract.

ii) Contaminated land can be cleaned to a variety of standards, (e.g. the standard required for a factory car park is lower than that required for housing). It is not reasonable to expect the consultant /contractor, working to a specification (given by the RDA client) to warrant that the site will be suitable for all purposes and all users in the future – which is the legal implication of these terms. The normal standard is to warrant that the work has been carried out with due care and diligence.

RDAs (or their legal advisers) argue that their public duty requires these contract terms and that they will be held to account should a problem arise and the consultant/contractor is found to have limited liability. In reality, they are limiting their selection of consultants and contractors to the small number of concerns who are prepared, for what ever reason, to take the unreasonable risks that these contract terms represent. Furthermore, in pursuing this policy RDAs are endangering the Government’s targets for the redevelopment of brownfield land.

The Minister could usefully explore this matter with RDAs to ensure that an appropriate balance is obtained between the need to demonstrate appropriate accountability for public monies with the necessity of redeveloping brownfield land.

4. Environment Agency

Notwithstanding liaising with Environment Agency officials in our Committee and Working Group, in day to day, site specific activities, our members invariably find interaction with the Environment Agency extremely frustrating for a number of reasons:-

i) There is no consistency between local offices. Although the specialists in the EA issue guidance (generally after public consultation), there is no onus on local offices to follow the guidance. Consequently each office (and each officer within that office) follows their own understanding of how to implement the policy/guidance. Consequently a development which would be permitted in one area, in another faces undue, excessive costs, delays and may eventually be refused permission.

ii) There appears to be no way of appealing against a decision made by a local office even when higher officials acknowledge that the decision is wrong. The process of appeal is very unclear and local offices appear to have unchallengeable autonomy.

iii) Guidance essential to the development of brownfield land is delayed – often for years. For instance, only a very small number of soil guideline values (that specify the permissible amount of certain toxic chemicals in soil) have been issued. Chemicals not covered by SGV’s must be assessed in some other (unspecified) way. The EA has the right to reject the conclusion of the consultant if officials do not agree with the methodology. The local authority regulator is therefore in an impossible situation when trying to assess proposals for brownfield land redevelopment (particularly for housing schemes). The recent disbandment of the National Centre will exacerbate this problem.

iv) EA policy leads to uncertainty. Developers expect their consultants to be able to advise on the measures which must be taken in order to obtain planning permission. Because of the uncertainties (above), consultants cannot be confident in their advice. However, if the consultant’s advice turns out to be unacceptable to the EA (resulting in additional costs and delays) the client may try to recover costs from the consultant’s insurance – putting further pressure on insurance requirements and the viability of consultants businesses. (See Item 2).

Action, direction and resources to rectify these problems at the Environment Agency need to come from Government. The Environment Agency is not currently fulfilling its stated functions with an appropriate balance. Unless improved guidance, consistency and expertise is forthcoming from the Environment Agency, the Government targets for the remediation and redevelopment of brownfield sites will be seriously jeopardised.

5. Waste Management Licensing 

It is becoming increasingly clear that regeneration projects on brownfield sites are being frustrated by Waste Management Legislation and the Environment Agency’s approach to its implementation. The crux of the problem is the recent move by the Environment Agency to interpret the definition of waste more restrictively. The result is that a considerable number of practices on site that were not previously considered necessary to regulate now fall within waste management legislation. The consequence of this is as follows:

i) The requirement for / presence of a Waste Management License (WML) on a development site will severely inhibit redevelopment potential of many sites. This is particularly the case for re-development of large sites where phased development is the only way to make the redevelopment process financially viable. The presence of an active WML on a housing development would effectively prevent sale of homes during the development programme.

(ii) Property Blight: New houses built on ‘licensed’ land are often seen as being built on the equivalent of ‘Waste Tips’ resulting in loss of value. A recent RICS report suggests the negative effect on property prices can be as much as 40%

(iii) Loss of potential for re-use of site derived soils: The reluctance of construction companies to operate waste management licenses will result in materials defined as waste being removed to landfill rather than being re-used as secondary aggregates (and the consequent need to import virgin aggregates from quarries and pits, entailing haulage and other environmental impacts of quarrying).

DEFRA and ODPM are developing the option of a Single Regeneration Permit to overcome the problems highlighted above. In reality however, the government is progressing inappropriate and increasingly restrictive legislation in isolation of the legitimate needs of the construction industry. It is important to note that other European countries are not interpreting the legislation in the same way and are not imposing similar constraints on their construction industries. This restrictive approach will jeopardise the achievement of the Government’s target of 60% of new homes on brownfield sites. Government is therefore urged to address this matter will all interested parties and in particular the Environment Agency.

Determination of Abundance and Activity of Soil Microflora Using Respiratory Curves

This standard specifies a test method for determining the activity of the active, heterotrophic microbial biomass in soils. The method is applicable to the monitoring of soil quality and to the evaluation of the ecotoxic potential of soils and soil materials. It is also applicable to soils that are contaminated experimentally in the field or laboratory (chemical testing) and for soils sampled along contamination gradients in the field.

It is one of a series of International Standards for biological test methods that have been adopted as British Standards – see list below. Further biological test methods are currently being processed in ISO TC190/SC4 (Soil quality – biological methods).
