ABOUT THE AGS

Chair’s Foreword Happy New Year to our AGS members and to all in the geotechnical and geoenvironmental community.

We are looking forward to a successful 2018 and the business of our Working Groups has already started with meetings taking place in January and February.

Despite the early shock of the collapse of Carillion, many are hopeful that the industry is buoyant enough to provide employment for all of their workers. Indeed, it appears that there is a certain amount of optimism for 2018 within the AGS membership, which is supported by the number of new companies who have recently joined us.

Continuing with our aim to promote quality and high standards within our sector, we have featured the National Quality Mark Scheme in this issue. This is a scheme that several AGS members have been involved in developing, together with some input from the AGS Contaminated Land Working Group. We 2

wish CL:AIRE success in their promotion of the scheme and look forward to the improvement of contaminated land reporting standards.

2018 is set to be a busy year for the nine AGS working groups and their leaders, with some of the output published in the magazine. We also have Members’ Day taking place on 11th April at the National Motorcycle Museum in Birmingham, and our Ground Risk event on 12th September at the Cavendish Conference Centre in London to look forward to. We hope to see you there.

If you’d like to register your attendance at any of our events, or provide feedback on AGS Magazine and our future plans, then please contact AGS@ags.org.uk

Aarsleff to use silent and vibration-free equipment to install sheet piled wall Aarsleff Ground Engineering has been awarded a sheet piling project that will allow the company to utilise its new Giken ECO 700S machine, allowing for the silent and vibration-free driving of sheet piles at Grovehill Depot in Beverley.

piles will form a retaining wall approximately 108 l/m for maximum retained height. A long reach excavator mounted with Movax unit will handle and pitch piles to the press unit.

Owing to the challenging site conditions, and wanting to deliver a safe and successful installation process, Aarsleff suggested a Movax unit mounted on a long reach excavator be employed.

The limited working room, poor state of repair of the access, and the bank slippage demonstrated to Aarsleff that it is not practical for a mobile crane to traverse, nor provide a realistic radius for lifting. By utilising the long reach, Aarsleff hope to ensure increased manoeuvrability

and lower bearing pressures, all at a safe distance from the embankment, allowing the site team to work from behind the press unit where previously installed piles have increased the stability of the embankment wall.

The Movax also allows us to safely and efficiently install and extract the necessary temporary reaction piles for the Giken press. Aarsleff’s head of sheet piling John Storry said: “The Giken enables us to provide cost effective installation programmes and solutions to our clients, even in the most environmentally sensitive conditions.�

A New Era for the AGS Data Format The AGS Data Format organisation is going through a period of change within AGS to ensure it can meet the demands of a digitalised industry. The way it is currently supported has to change. Jackie Bland explains…

The AGS Data Format stands as one of the most useful digital standards ever developed for our industry. It’s the product of collaboration between likeminded technical experts who all saw the need to share site investigation data in a standard way between their different organisations, irrespective of the software and people involved. Yet for many its purpose is unknown or not understood.

The AGS Data Format saw a group of enthusiasts come together with no budget and little dedicated time to create something that has become a defacto standard within the UK Site Investigation industry.

Although the NQMS can be applied to the management of land contamination under a range of regulatory regimes, its primary focus is to improve the quality of work done to manage land contamination under the Town and Country Planning System. However, it could also be applied to Part 2A, environmental permitting, pollution incidents and enforcement actions.

The SQP Provider is the organisation which examines the capabilities of prospective SQPs and compiles a register of their details.

This role is currently carried out on behalf of the Land Forum by SiLC (Specialist in Land Condition Register). There are two routes whereby an individual can become an SQP.

Preventing Lyme Disease Risks, Controls, Symptoms and Treatments

T

the following areas: the New Forest; Exmoor; South Downs; Thetford Forest; woodland and heathland in Southern England; Lake District; North York Moors; and Scottish Highlands and Islands.

Ticks favour a moist, shaded environment especially that provided by leaf litter and low-lying vegetation in wooded, brushy, or overgrown grassy habitat. Both deer and rodent hosts must be abundant to maintain the life cycle of the tick.

In the UK, the risk of tick bites is highest from April to October, when the ticks are most active.

They are picked up when clothing or hair brushes a leaf or other object the tick is on.

Ticks are generally found within 1 metre of the ground and, once picked up, they will crawl until they find a likely site to feed. Typically Lyme disease is an infection caused by the this might be at the back of the corkscrew-shaped bacterium knee, near the hairline, behind Borrelia burgdorferi that is Ticks favour the ears, or at pressure transmitted by the bite of a points where clothing a moist, shaded tick. The ticks feed on birds environment especially presses against the skin. and mammals that carry the The size of a tick varies, that provided by leaf bacterium in their blood and depending on the stage of litter and low-lying then transmit the bacterium its life cycle, gender, species to a human when they bite vegetation... and whether it has fed and feed. The tick needs to be recently. The photo in the attached to a person for about margin shows (left to right) adult female, male, 24hours before the disease can be transmitted. nymph and larva on centimetre scale. here are around 900 reported cases of Lyme disease in the UK each year, although estimates suggest there may actually be 2000–3000 cases.

“

Those at particular risk from the disease include sheep farmers, deer farmers and veterinary surgeons but geotechnical and geoenvironmental engineers may be at risk when working in the field in high risk locations (see below).

Control Measures

•

Be ‘tick aware’ in high risk areas.

Risk Assessment

•

Wear light coloured clothing to allow you to see ticks that are crawling on your clothing.

•

In areas of long grass, wear long trousers tucked in to socks.

•

Wear high rubber boots, or use tape to

The ticks which spread Lyme disease are common in forested areas, heathland, moorland and suburban parks. However Lyme disease is most likely to be acquired in

The following control measures can reduce the risk of infection:

close the opening where they meet so that ticks. cannot crawl up the inside of your trouser legs.

•

Wear a hat, and tie back long hair.

•

Check exposed skin and clothing for ticks (they are very small and therefore difficult to see) and remove immediately.

•

Use insect repellents (repellents containing permethrin can be sprayed on boots and clothing, and will last for several days).

•

Because it takes several hours of attachment before microorganisms are transmitted from the tick to the host, prompt removal of attached or crawling ticks is an important method of preventing disease.

•

To remove ticks use fine-tipped tweezers ( see photo in margin) . Grasp the tick as close to the skin surface as possible and pull upward with steady, even pressure. Do not twist or jerk the tick; this may cause the mouthparts to break off and remain in the skin. The danger of pulling the body off and leaving the head in the skin tissue is that this may lead to infection. Do not squeeze, crush, or puncture the body of the tick because its fluids (saliva and gut contents) may contain infectious organisms.

•

After removing the tick, thoroughly disinfect the bite site and wash your hands with soap and water.

•

Seek medical advice if you develop flu-like symptoms after visiting high risk areas.

Symptoms Where infection does occur then the incubation time is between 3 and 30 days so the symptoms may not obviously be associated with the exposure. There is a significant risk therefore that the symptoms may go undiagnosed. Some, but not all people with early-stage Lyme disease, will develop a distinctive circular rash (see photo below) which spreads from the site of the tick bite. It is not generally painful or itchy. There are often accompanying flu-like symptoms such as tiredness, muscle pain, joint pain, headaches, fever, chills and neck stiffness.

More serious symptoms may develop several weeks, months or even years later if Lyme disease is left untreated or is not treated early on. Later symptoms may involve the joints, heart, and central nervous system. A few people with Lyme disease go on to develop long-term symptoms similar to those of fibromyalgia or chronic fatigue syndrome.

Treatment In most circumstances, medical treatment of persons who only have a tick bite is not recommended. Otherwise in most cases, the infection and its symptoms are eliminated by antibiotics, especially if the illness is treated early. Anyone with these symptoms who has been in a high risk area should seek medical attention. Save the tick for identification in case you become ill.

BSc. (Hons), MSc, DIC, CGeol, FGS Job Title: Regional Manager and Associate Geotechnical Engineer Company: Coffey Geotechnics Ltd, a Tetra Tech Company Brief Biography: After nearly 30 years in the geotechnics industry, I have worked on many aspects of ground engineering and currently have responsibility for technical management of a wide range of operations and for design delivery.

I have a background in site investigation but have since worked for design consultancies for many years on significant transport and energy infrastructure schemes.

Because of this, I am well placed to represent the consultancy sector as part of this important trade association.

What are the most challenging aspects of your role?

The main challenge is always the tight timescales imposed on us by many of our clients – either due to them not being aware how much they will need geotechnical specialist input on a tender or design until very late in the day, or due to delay of award date of a scheme but not of the delivery date. This constraint can affect the entire design team, not just in geotechnics.

Another key challenge is and what are your current trying to ensure that the focuses? ground investigation data we rely on so heavily as designers I have been on the Executive Committee and now the is available in AGS format Senate since 2014 and am to those that need it.

undertaken to dwellings, there is a tendency to view this as ‘simple building works’, on par with a rear extension or loft conversion.

However, this is not the case.

Basement Construction Works

Irrespective of its size, construction of a basement involves significant excavation of soil and the use of temporary works. It requires a fully engineered approach to the scheme, to address issues associated with the loads from the soil, existing structure and surrounding structures, and to ensure issues of groundwater flow and surface water flow are adequately addressed.

Since domestic basement construction is

ncreasing the size of domestic properties by digging basements has become very popular in recent years. This can involve constructing a new basement under an existing property or the complete redevelopment (demolition and reconstruction) of a property. This client guide describes the key ground engineering aspects associated with the planning of domestic basements so that those proposing to undertake such works will have a realistic idea of what is involved.

onerous and detailed. Failure to meet these requirements will typically result in the application either failing to be validated or being refused, wasting both time and money.

Therefore a property owner (or their agent) planning domestic basement works should make sure that they are familiar with the requirements of their local planning authority, and then ensure that they have adequately budgeted both money and time to meet all the requirements. Attempts to skimp on the submission will invariably prove to be a false economy. It is possible to seek pre-application advice from the Local Planning Authority, although there is no consensus among professionals in the industry as to whether such advice is useful.

Ground Investigation Basement excavation requires digging a large hole in the ground. The ground alongside and beneath the hole will respond to this by moving. The structure of the new basement itself will also place new loads into the ground, which typically causes further complex movements combining both heave and settlement. If these movements are excessive, the new structure may become damaged, or fail completely and become uninhabitable. therefore be aware of the need to have Where there are existing specialist geotechnical and structures to be retained on structural engineering input If these the site over the basement early in the development of movements or close by the works, these the scheme, in addition to are excessive, the may be affected by the the perhaps more obvious resulting ground movements, new structure may requirement of obtaining the suffering damage.

Construction works on site will typically take many months, quite possible well in excess of one year, depending on the size of the development.

An early and comprehensive consultation process with neighbours is advisable. This enables issues of concern to be addressed early on, and often enables suitable mitigation measures to be introduced. Moreover the simple act of consultation and informing neighbours of works in advance can help to reduce objections to the works.

Property owners undertaking domestic basement construction projects should also be aware that such works are often subject to the requirements Excavation will generate many truckloads of the Party Wall Act 1996 (the PWA).

A well planned basement development, properly designed and constructed by a competent contractor, should be constructed with no significant problems...

Contractor Competence and Insurance A well planned basement development, properly designed and constructed by a competent contractor, should be constructed with no significant problems, and without generating excessive ground movements or damage to the existing or neighbouring properties.

While a client may choose how they wish to identify a competent contractor, it is recommended that they select a contractor that is a member of a relevant trade body, for example: • ASUC, the Association of Specialist Underpinning Contractors: For retrofit basements constructed using underpinning techniques. ASUC members are required to demonstrate a level of professional

competence, and the trade body offers insurance guarantees (www.asuc.org. uk).

• Federation of Piling Specialists (FPS): For basements constructed using perimeter bored pile walls (www.fps.org.uk).

While basement works normally proceed without incident, there is the potential for incidents to occur which may lead to damage to the client’s or other people’s property. Additionally, the construction of a basement will result in a considerable structural alteration to the property. Anyone considering a basement development should therefore also contact their own insurers to inform them of the proposed works; to ensure they retain insurance cover throughout the works and thereafter for the completed structure.

Consideration should also be given to issues of security for the site and for neighbouring properties both during the works and for the completed structure.

Liaison with utility providers is also likely to be required, with drainage issues often requiring particular attention.
