CHALLENGES & SOLUTIONS

Working around sensitive services. For instance, the design consisted of the removal, over pumping and replacement of a 900mm diameter concrete foul drain crossing the line of pipework which we undertook by threading the DH pipe carefully under the foul drain, resulting in a significant value engineering saving for the Employer and de-risks this part of the project.

In order to meet the challenging Employer heat on dates in phase 2, we accelerated the works by increasing our resources, working in multiple areas and planning the works in such a way as to avoid disruption to local residents and businesses. This required careful engineering and planning due to the extremely low tolerances involved in joining pipes laid in separate sections.

As part of our project scope we liaised with local residents and stakeholders, keeping them informed of the works as they progressed as well as undertaking enabling works such as temporary car parking bays, temporary bin locations and installing new residential drainage connections.

Working in UXO listed area under UXO specialist supervision and implementing suitable methodology.
