Project Blue, Severnside, Bristol

Client: Severnside Distribution Land Ltd

Value: £2.96m

Contract: ICE Minor Works 3rd Edition

Following the successful completion of Project Red, Dyer & Butler delivered a further two phases of enabling works at Severnside. Phase 1 involved significant site clearance works, construction of carriageway and associated drainage, culvert construction, and underpinning works to stabilise the existing high pressure oil pipeline running through the site. Phase 2 involved fill to the redundant reen network, construction of embankments, and carriageway construction. The works were completed within budget and ahead of programme.

 

The project provided significant enabling works to the construction of a large distribution park located between the Severn Beach and the M49.

The project was split into two phases and comprised the following construction activities:

Phase 1

  • Site clearance
  • New embankment construction including wick drainage and settlement monitoring
  • New carriageway construction
  • Storm water drainage
  • Construction of 30 metres of pre-cast concrete box culverts
  • Underpinning of 125 metres of high pressure oil pipeline

Phase 2

  • Filling the redundant reen water network over 1.4km
  • New embankment construction including wick drainage and settlement monitoring
  • New carriageway construction
  • Storm water drainage
  • Construction of a new 35 metre diameter roundabout
Value Engineering

A composite single membrane that matched the specification performance in lieu of two separate membranes was proposed by Dyer & Butler. Following laboratory performance tests, the alternative membrane was accepted by the designers and Local Authority and the proposal provided a cost saving of £55,000 to the project.

Dyer & Butler proposed an alternative solution to protect an existing gas main which traversed the site which provided a cost saving of £6,500 to the project.

 

100% of the topsoil stripped from the site was re-used on the site and 40% of the imported 6F5 was a recycled material.

Dyer & Butler achieved a CEEQUAL award for this project where contractors go beyond the legal, environmental and social minima to achieve distinctive environmental and social performance in their work.

 

Underpinning the oil pipeline was a potentially hazardous operation. Through careful planning, stringent control measures and close liaison with the pipeline operator, the works were completed without incident and within the programmed duration for this element of the works.
