A350 Chippenham Bypass
MJ Church have recently completed works for Wiltshire County Council as main contractor on the Chippenham Bypass, widening Bumpers Way and converting the A350 to a dual carriageway at 3 sections to improve traffic flows. Starting in July 2015, the scheme was programmed to complete within 38 weeks and despite minor changes to the design mid-construction and the discovery of a cable which needed relocating, completion was achieved in February 2016 – within 31 weeks. Finishing works 7 weeks ahead of schedule ensured minimal disruption and congestion to the travelling public.
The scheme was carried out from approximately 350m South of the junction with the A420 (at Bumper’s Way roundabout) through to a point 320m North of Brook roundabout, both roundabouts were already built to accept the widening.
Working together with various appointed subcontractors, the contract involved traffic management, site clearance, service diversion, earthworks, drainage & ducting, sub-base, kerbing, planing & surfacing, streetlights including cabling & connections, signage, barriers, parapets & guard rail, concrete stepped barrier, fencing, construction of culvert extension with wing walls, clearance of culverts, bollards, road marking, landscaping and soiling & seeding.
In addition to completing ahead of schedule, MJ Church were able to use approximately 1,500t of locally sourced recycled crushed concrete material from the demolition of various buildings at nearby Wiltshire College. The material was collected by our in-house fleet and used directly on site instead of using primary quarried material, reducing our environmental impact, lorry movements and costs.
