Project Overviewx

ACS were employed to undertake the design and construction of the Final Phase works comprising 63 No. Static caravan bases, access/service road, car park hardstandings and refuge areas along with all associated services, drainage and landscaping works at Lee Valley Caravan Park.

Following the completion of a robust public sector tender and interview process, ACS were appointed to deliver a £1.9 million civils contract to design and construct the final phase expansion works at Dobbs Weir in Hertfordshire. In our role as Infrastructure and Civils Contractor we were carrying out a complete turnkey contract over 24 weeks. The works were executed under a JCT Design and Build Contract with ACS maintaining a ‘fit-for-purpose’ design liability.

One site specific risk that was identified at tender stage was the high water table present across the work area. In order to mitigate risk for all the project stakeholders, ACS deployed a Dewatering “well point” system which kept the area free of grounwater while work progressed. This is of particular importance when constructing the Pumping Station chambers which were 6m deep. Excavation works commenced for new mains and foul water, electric and gas supply and two new pumping stations 4.5m deep.

ACS’ integrated design and operational teams, added value for Lee Valley Regional Park Authority through the implementation of performed drainage systems keeping the system water tight and reducing project duration. Other value adding design features include the installation of a Geogrid system which reduced the fill requirements across the scheme.

ACS offered and the client accepted significant V.E. options. Saving circa £60k off contract sum which did not affect scope or quality. These consisted of advanced ground modelling and reconfiguring intial tree protection.
