Case Studies - Civil Engineering
A77 Hansel Footbridge
Cadogans were appointed as Lead Consultant for this Design & Build Project – a 33m span footbridge across the A77 in Ayrshire, complete with ramps and stairs.
Cadogans provided a large team of engineers to support Transmanche Link (TML) in its engineering, contractual and financial disputes with Eurotunnel. The team was based at the site for about three years.
Concrete cladding panels
There had been some problems with the external concrete cladding on a stair tower of a large building. An inspection was carried out and proposals for remedial works prepared by a local small consultant.
ECML Bridge Cladding
Cadogan Consultants were appointed as Checker for the rainscreen cladding to be fixed to the sides of the ECML Bridge near King’s cross, London.
Failures arising from construction works
A building owner gave a contract to a design team to construct extra floors on an existing building. Cadogans was asked to investigate the performance of the mechanical and electrical engineering consulting engineer and whether the standard was what would have been expected from a reasonably competent and diligent practitioner.
Flooding of house and garden
A house developer constructed a SUDS (sustainable urban drainage system) pond at the corner of a site that it was developing for new housing. A homeowner shared a mutual boundary with the developer’s site adjacent to the SUDS pond. Three to four years after the SUDS pond had been constructed the homeowner claimed that the SUDS pond was responsible for water surcharging under their property and up through the front garden causing extensive damage.
Hunterston Weather Envelope
British Nuclear Group is decommissioning Hunterston, a nuclear power station. The decommissioning strategy adopted by them includes transforming the reactor buildings into ‘safestores’ to allow the residual radioactivity to decay to a low level. The life of the transformed building is to be 100 years.
The millrace was a man-made lade or channel which was constructed in the 19th century to supply water as required to a former mill in the harbour area. At that time water flowing into the millrace was controlled by a sluice gate at its junction with the adjacent watercourse. The watercourse was channelled, culverted and piped over most of its length.
Power Station disputes - Eastern Europe
Cadogans became involved in an international arbitration relating to disputes at two oil shale-fired power stations in Eastern Europe.
Progressive collapse of a building
The building had become derelict following a fire. In the fire the roof had been mostly destroyed and there were various local areas of fire damage throughout the building.
Retaining Wall Failure
A major, national UK contractor, whilst excavating in front of an existing 8m high masonry retaining wall to construct an access road into a new healthcare facility noticed that the wall had started to move forward.
Roof anchor accident
Cadogans provided an opinion on Health and Safety matters arising out of an accident at an industrial building. The main issue was whether or not there were anchor points on the roof to which the Pursuers could have attached safety harnesses, at the time of carrying out their work.
A new waterfront retaining wall was constructed at a seaside resort. The new retaining wall required to incorporate a sewer outfall near the base of the wall. The wall was constructed around the outfall but shortly after completion of backfilling behind the wall, the ground level was noticed to have sunk considerably immediately above the line of the sewer at the position of the outfall.
Shuaiba Oil Pier Civil Engineering
The project comprised the rehabilitation of Shuaiba Oil Pier which had been extensively damaged during the Iraqi invasion of Kuwait. The pier comprises a North Arm and a South Arm, each having an inner and an outer berth suitable for very large crude carriers (VLCCs). The berths are linked to the shore by a 1km long Approach Trestle.
Site preparation work KG Ethylene Plant
The firm designed, supervised and reported on detailed ground investigations for foundation and earthworks design in connection with the KG Ethylene Plant Expansion Project at Grangemouth. The interpretative reporting included consideration of the geotechnical, flooding and draining aspects of site development.
Trip at carriageway road gully
A pedestrian was attempting to cross the road in a town in Scotland. Stepping off the pavement onto the road carriageway, she stumbled and fell at a sharply sloping area at a road drainage gully. She sustained a double fracture of the leg.
Victoria Tower Aberdeen
The project comprised detailed option appraisals; considering cost, fire safety, engineering suitability and structural impact; followed by design, specification and site supervision of the replacement of the existing heating, ventilation, electrical services and a large proportion of the water and drainage services to a large multi-storey 1980’s office complex.
