_Client:

_Value:___
£6 Million
_Duration:_
2005 - present
|
- The
construction of approximately 8km of new and improved roads together
with numerous structures located within a narrow and densely populated
valley environment.
- The
ECI project was awarded to Costain Ltd in September 2004 with
a 13 week Interactive Development phase to develop a Target Cost,
followed by a 13 week Value Engineering Period.
- Walters
UK worked closely with Costain during the pre-qualification and
tender stage including full representation at all pre and post-tender
client interviews and workshops - a major factor in the decision
to appoint Costain as Main Contractor.
- Based
on the clients design an initial target cost for earthworks of
£9 million was agreed during the Interactve Development
Phase. By working as a co-located, intergrated team with the Main
Contractor, client and design team, this figure was subsequently
reduced to £3 million as follows.
-
Off-site disposal reduced from 235,000m3
to on-site disposal of approx. 85,000m3.
- Excavation
quantities reduced from approx. 300,000m3
to 180,000m3.
- Disposal
of contaminated material (domestic rubbish) reduced from 13,000m3
to 4,000m3 by additional Sl undertaken
during the Value Engineering Phase.
-
To remove the need for a river diversion, the team proposed
relocation of a roundabout into the base of an adjacent mountainside
requiring additional rock excavation. This additional cost
was subsequently negated by crushing the resultant rock to
replace approx 15,000m3 of imported
granular fill
