D&B – Tender / Construction Stage

Approach

John has worked on design and build schemes at tender and delivery stage as a contractor and designer as well as assessing tenders on behalf of a client. This provides him with a unique insight into how each of these differ and the processes and procedures adopted by each.
When working for a contractor John will be able to work with the appointed consultant to help them to 'challenge the norm' and develop solutions that push design guidance to provide efficiencies, bring innovations from past projects and look at new ides that improve their quality score as well as reduce the cost of construction. This can be done at tender stage or during the design and construction period.
He will also assist the team with bid strategy and if required he can review the quality submission as part of the review team.

Benefits

  • Improved quality score
  • Reduced cost of construction
  • Optimised design and delivery programme
  • Reduced carbon and more sustainable approach
  • Provides an edge over other tenderers
  • Identifies alternatives and savings during delivery stage
  • Reduced risk and increased opportunity
  • Utilise best practice and shared knowledge

Experience and Evidence

John has worked on a variety of D&B projects in highways, rail and LRT including the A14 J7-9, Werrington Grade Separation, Doncaster North bridge, M42 J6, Leeds Public Transport Investment and Leeds Southern Entrance to name just a few (For a full list of contracts John has worked on see the About page).
The concrete gabion was developed for the A14 J7-9 tender and utilised rectangular manhole rings to form the structure. It was then backfilled using as dug material from site and replaced 1.2km of sheet pile retaining wall shown in the illustrative design and could be built by low skilled labour. This contributed towards reducing the cost of construction along with retaining 90% of the central reserve (barrier, drainage and lighting) and removing all works at junction 7 by retaining the current layout.   For Linton bridge John worked with the contractor (BAMN) to temporarily stabilise a deformed arch which had rotated and cracked due to the adjacent pier settling 200mm after a flood event. The issue was that the arch could collapse at any time meaning that people could not go near or under the arches. John developed the idea above which allowed trestles to be installed within the safe zone and support beams and formwork floated beneath the structure before being hoisted into place (a 3D drone survey was undertaken to determine the shape of the arch).
