About the project
The A4233 is the only main road through the Rhondda Fach Valley in South Wales, so the aim of this £90 million scheme was to provide environmental and safety benefits by removing traffic from a densely populated residential and commercial area.
The project was completed in December 2006 and comprised of 8km of new and improved carriageway, a 90m span Bowstring Rheola bridge in Porth town centre, 10 bridges, 15 retaining walls and 16 culverted watercourses. Works were often carried out within 10m of the Rhondda Fach river.
The Porth Relief Road scheme was awarded a number of national Constructing Excellence Awards including the ‘Best of the Best Award’ in recognition of its excellent promotion of the Constructing Excellence principles.
ChandlerKBS were part of the team that procured the scheme using an ECC Option C Target Cost Contract. We advised on compliance with EU Procurement Legislation and the compilation of contract documents, and were instrumental in the developing the target cost, which required a high degree of value engineering to produce a scheme within the available budget.
ChandlerKBS also carried out benchmarking exercises to ensure that the final agreed target cost represented value for money.
