This complex scheme next to the M5 in Bristol has involved significant traffic management on the A4018 dual carriageway to enable the remodelling of the existing, and the construction of new, junctions during live flow conditions. When completed, these will provide access to a new significant housing development. Montel is also constructing the bulk earthworks and primary infrastructure across this 50-hectare site. The A4018 provides a strategic link between the M5 and the south and west of Bristol and as well as the Cribbs Causeway “Mall” retail centre being within a kilometre of the project, there are a large number of commercial properties fronting onto the dual carriageway.
The network is busy at all times, both with motor vehicles, cyclists, and pedestrians; exacerbated by the fact that it is also a bus route into Bristol city centre. Through early dialogue with South Gloucestershire Council, Montel’s works phasing and associated traffic management was compiled and implemented with the traffic flows being a major constraint – with the sequencing used by us done to so accommodate the more extensive requirements of the local highway’s networks. The wider works included in the project consisted of:
The highway works have required the direct liaison with all Statutory Undertakers due to the presence of numerous and significant utilities along the existing highway. Through early contractor involvement (ECI) Montel were made aware of the presence of all known services and were able to coordinate and manage the protection or diversion works necessary to allow the permanent works to be safely undertaken. These services were exposed through a combination of trial holes, vacuum-excavation, and hand excavation and were either diverted or protected as dictated by the asset owner.
For this complex highway’s project we invested significant time assisting our client with tender stage programme phasing, value engineering, and budget costing to ensure that the procured scheme offered the optimum solution. Phasing and traffic management plans were compiled, tabled, and discussed face-to-face at regular meetings with the South Gloucestershire highways and network management teams, the design team (Phoenix Design Partnership) and representatives of the Statutory Undertakers, with Gantt-chart programmes produced which were also instrumental to understanding the durations associated with each phase of the works.
To further assist our client, and to help them discharge their planning obligations, Montel also provided both Construction Phase Health & Safety and Construction Environment Management Plans for submission to the local authority. The latter of these provided a narrative as to how we anticipated to manage the site and the local environment, and our project team then instigated and proactively managed meetings with the teams from South Gloucestershire Council – and their interested stakeholders (such as the bus companies) – to discuss and agree traffic management sequencing, durations, and methodology in advance of the project starting.
Montel work collaboratively with our clients to ensure that all works are managed in a manner which provides confidence to our clients and their teams.
