High Speed 2, Phase 2a ACD Scheme, UK, 10/2021 – 05/2022

Client: HS2 Ltd

Phill was the Drainage Technical Discipline Lead within an integrated JV team responsible for the design of all drainage systems associated with the HS2 Phase 2a Advanced Critical Design (ACD). This project was split into tasks, where Drainage input is required for 4 out of 8 tasks. Responsibilities include for the “Scheme Design” of a 10km section of open route, which involves understanding the detailed design of track drainage to ensure full coordination with earthworks, track systems and noise fencing. Working with Network Rail as a partner, a GRIP3 drainage design for the existing WCML corridor is also being developed to provide a more resilient and sustainable drainage system. In addition, the layout of the tunnel portal areas include for associated drainage works, such a pumping station compound, potable water firefighting supply tank and contaminated water holding tank.

HS1 Tunnels, UK, 01/2022 – 04/2022

Client: Network Rail High Speed

Phill was the Drainage Design Lead responsible for the design of the tunnel drainage system associated with an on-going issue of groundwater entering the tunnel through displaced joints and failed grout plugs. The solution was to be simple, cost efficient and be flexible to apply to other areas of the tunnel, where required. After an assessment of several options, the final solution was to provide saw cut channels in the concrete walkway, leading to a narrow channel affixed to the vertical wall; which discharges into the central drain under the rail tracks.

A120 bypass (Little Hadham) and flood alleviation scheme, UK, 09/2021 – 11/2021

Client: National Highways

Phill supported the on-site design team with some drainage design changes which were required following detailed site investigation returning infiltration rates less than originally designed for. The initial drainage design associated with an underpass under the newly constructed A120 mainline consisted of deep bore soakaways and geocellular attenuation tanks. As much of this solution had already been constructed it was necessary to find a solution that utilised this system as far as practicable. After testing several options including for a pumping station, additional storage and additional deep bore soakaways, the final solution involved the reassessment of the design parameters which resulted in amending the runoff coefficient used for the cutting slopes. By demonstrating that the constructed design was sufficient to meet the Local Authority requirements, the final design was approved; saving the project approximately £150,000 and avoided any risk with meeting the programmed opening date.

Client: FCC Environment

Phill was Lead Engineer responsible for discharging a Planning Condition in relation to providing full details of the surface water drainage scheme on a proposed Mechanical Biological Treatment (MBT) facility. As the site is based in Scotland, close liaison with the Scottish Environment Protection Agency (SEPA) was required to ensure that the final solution would meet their strict criteria. The solution consisted of three management trains in areas where potential pollution incidents were high risk, which included for dry swale along the perimeter boundary, an attenuation lagoon and wet swale prior to final discharge. This ensured that the water quality entering the local watercourse was acceptable to SEPA. As the site was in detailed planning, it was necessary to fully understand how the system operate and therefore the design accounted for ground levels, site constraints and materials used.

Client: Environment Agency

Phill was Project Manager and Lead Engineer for the relocation of a rising main and outfall within a SSSI. Responsible for the design of the works, the financial management and management of a specialist within another office. To avoid the need to affect the SSSI in any way a directional drilling technique was proposed to lay the new pipe. The client was highly supportive of using this technique as it would ensure that wildlife and the woodland was left unaffected by the construction works. A new set-back outfall was designed to dissipate the pumped flows by including for a rock gabion mattress filled with rushes and reeds. Other duties included for undertaking the role of ECC-PM/Supervisor during the construction works to ensure that works were completed to the specification, on time and within the budget.

The application included for the replacement of existing buildings within the Camp and the inclusion of up to 90 houses in the SFA, which resulted in an increase in surface water flow, foul water flow and utility demand requirements. The surface water strategy included for sustainable drainage systems (SuDS) such as infiltration and conveyance techniques. There was a need to divert and lay new foul drainage networks across the new site layout and was also a need to assess and discuss utility demand requirements with the relevant suppliers.

PICP Support to Cable and Wireless Worldwide, UK, 03/2010 -05/2011

Client: Cable and Wireless Worldwide

Following certification to ISO 14001 in February 2011, C&WW identified sites across the UK with fuel storage above 10,000 litres that required site specific Pollution Incident Control Plans (PICP's).
