We design on-site and off-site roads, levels and drainage for residential, commercial, employment, education, health, leisure and logistical developments.

Achieving satisfactory vehicle access is the key to unlocking development sites.

PJA’s development infrastructure engineers and transport planners identify feasible access options, working with relevant design guidelines and negotiating with authorities at local and national levels.

We are proficient in the design of new estate roads and hardstanding whilst balancing the need for cut and fill to provide the optimum development layout using 3D ground modelling.

Our talented infrastructure design team has a wealth of experience in the design of adoptable drainage solutions, diversion agreements and WSUD, as part of obtaining statutory approvals for residential and commercial developments.

Provision for adequate drainage is of paramount importance during the design of road and site levels. As part of the design works, we also undertake detailed earthworks modelling using 3D design software.

PJA can offer drainage solutions during the development of the masterplan, as part of planning works, detailed design works and subsequent maintenance works including stormwater drainage strategies, WSUD design, pumping station design and hydraulic modelling.
