“To my knowledge Knowsley has not received a single complaint regarding this scheme which is a testament to the professional and courteous attitude shown by the work force on site. Could you please pass on mine, my colleagues and the resident’s thanks for their efforts. They have made the whole scheme run very smoothly.”
County Road Roundabout
Case study: Other
County Road roundabout is a four arm roundabout that has four busy carriageways leading directly onto it. The roundabout is located in the Kirkby area of Knowsley and serves many of the commercial premises on the adjacent Knowsley Industrial Park, as well as a lot of traffic from local residents.
A lot of the traffic for the industrial park are HGV vehicles that have worn away the existing carriageway meaning the circulatory carriageway had to be excavated to a depth of 400mm, whilst the surrounding carriageways were planed out to a depth of 100mm. The circulatory carriageway was then constructed with 100mm of type 1 stone, 2 courses of 100mm heavy duty road base, 70mm of heavy duty binder, before 30mm VIATEX being applied.
During the reconstruction of the circulatory carriageway, new highway drainage was installed as well as traffic signal ducting and chambers. This would provide sufficient surface water runoff and would make the installation of traffic signals a much easier task in the future. Under KMBC’s aboriculturist guidance the removal of approximately 15 – 20 medium sized trees
The scheme was carried out under a road closure and was programmed to take six weeks to complete. The cost of the scheme was estimated to be £315,000.00 and to minimise disruption to local businesses and residents our work teams had to carry out 7 day work shifts to finish the scheme as quickly as possible.
Due to HGV’s requiring access to the industrial park, traffic flows disrupted by the scheme had to be carefully planned and routed so as not to cause too much disruption to residents of the surrounding area. Our Framework Manager and his team worked from the initial consultation with KMBC and their agents to develop a fully phased project and health and safety plan, taking into account all of the traffic management concerns. The scheme was completed in two phases directing traffic through the adjacent ‘A class’ routes on phase 1 and through the industrial park during phase 2.
The scheme was completed both on time and on budget.
Achievements against targets:
Additional works were added to the scheme. The scheme was completed to the expected target date and cost.
