CEEQUAL rewards best environmental practice on civil engineering projects. This is our first review of the scheme and some of the projects making the grade. Close to £9bn of projects have been or are being assessed by the CEEQUAL scheme. Projects can be big or small and are graded as pass, good, very good or excellent.

Black & Veatch/Costain/Bristol Water
The scheme comprised two main projects − Barrow Reservoir and Pumping Station and the Northern Relief Main a 13km pipeline scheme. The project was carried out by the Bristol Water AMP4 Framework team. Access to the site was limited as the reservoir was constructed between two areas of ancient woodland. The main challenge during pipeline construction was mitigating the risk of landslips in lower lias clay at the base of Dundry Hill.
Bristol Water Northern Strategic Support Scheme
- Start/finish: September 2005-March 2008
CEEQUAL Awards attained:
- Barrow Reservoir and Pumping Station: Excellent award − Whole Project
- Northern Relief Main pipeline scheme: Good award − Whole Project
- Reservoir site was selected to reduce pumping requirements and minimise carbon footprint
- Careful planning of cut and fill meant that no material was taken off site
- Environmental mitigation measures taken, including nesting bird surveys before hedgerow removal and white clawed crayfish watercourse surveys
- Sections of felled oak trees placed around site for insect habitats and bat boxes installed in ancient woodland
CEEQUAL is helping Carillion achieve its mission to make tomorrow a better place. With three ‘Excellent’ awards already, another five awards in process and our own in-house CEEQUAL-trained Assessors and a Verifier, our involvement and commitment is virtually unmatched. As seen by our examples below, we have a strong reputation of balancing the need for economic and infrastructure growth and opportunity with environmental protection and the conservation of natural resources and heritage. We’re proud to be working with CEEQUAL - an organisation that shares our values and priorities.

St Ives Stennack River Flood Defence Scheme

- Project Team: Environment Agency (client), Carillion (formerly Mowlem, contractor), Halcrow (designer)
- Start Date: April 2006
- Finish Date: August 2008
- Tailor-made solution involving pioneering techniques, never used before by the Environment Agency: Cross drains to catch rain-water and divert it into culverts; a carbon calculator and a ‘living wall’ made of fast-growing willow on the riverbank to slow down flood water, prevent erosion and provide habitat for wildlife
- The scheme was redesigned in places to retain mature trees
- Improved water quality in the River Stennack and on the beach by diverting misconnections and dirty water discharges to sewers
HCA , Birse & Halcrow
These major road and flood attenuation works provide for the future development of up to 12,000 houses. The 1.5km link road joins the A4500 Weedon Road to the Swan Valley employment area, and crosses the River Nene’s floodplain on embankments that are integral with 6km of flood attenuation bunds. Together these provide a network of elevated pathways through the Country Park.
The construction took place through and between County Wildlife Sites, with prominent ecological resources. Ecological mitigation measures were essential to achieve net biodiversity gain from the project. Halcrow ecologists were integral to the project team and worked closely with the Environment Agency and Northamptonshire Wildlife Trust.

- All waste separated on site for appropriate disposal or recycling
- Construction methods, plant and machinery chosen to limit noise and vibration levels
Team Van Oord
The aim of this project was to maintain the integrity of the flood defence embankment and to provide enhancement through the creation of salt marsh habitat. The Environment Agency has invested significant funding into ensuring that this sensitive site has been retained using soft engineering techniques.
Environmental and logistical problems were overcome by the use of innovative techniques. These included the use of a long reach excavator mounted on a specialist jack-up platform for the tidal installation of the timber stakes and brushwood mattress.
Dartford Creek Frontages
- Start/Finish: August 2006-September 2007
- Cost of project: £4.9M
- CEEQUAL score 84.6%
- Development of a soft engineering solution
- Use of brushwood faggots sourced from sustainably managed coppicing of ash and chestnut
- Profiling to create natural tidal creek embankments and river meander
- Innovative use of geotechnical and river engineering techniques
The Alkborough project was designed to help manage flood risk on the Humber Estuary. Now
the largest manmade wetlands in Europe, it safeguarded and enhanced wildlife habitats, helped with wider tourism
projects, involved the local community and adapted the construction timetable to suit farming cycles. These are
just some examples of how we believe sustainability can work alongside engineering.

- Commitment to sustainable construction practices and taking a proactive approach
Welsh Assembly Government/Atkins/Jones Bros
Parc Cybi is a strategically important site for the economic regeneration of Holyhead and Anglesey. This project includes offices, factories and a leisure complex, and 150 new homes. Set within an Area of Outstanding Natural Beauty, the Welsh Assembly Government’s concept was for a carbon neutral development.
