The Ilford Yard Stabling Project was a rail infrastructure scheme to provide additional stabling for new Crossrail rolling stock along the north-eastern section of the Crossrail network. The works involved the partial demolition of existing facilities at Ilford Depot to accommodate the proposed Crossrail stabling sidings and location of new operations and welfare facilities on the Ilford Depot site. Upon completion, this project forms part of Crossrail, one of the largest schemes of its kind in Europe.
Having had previous success with depot electrification projects at Three Bridges and Williams Way with Volker Fitzpatrick (VFL), RJ Power Rail (RJ Power) was invited to tender for the provision, installation and subsequent test and commissioning of the electrical power works associated with Stages 3-7 of the Ilford Yard Stabling works.
Under the expert guidance of Matt Woolley, Sales Director of RJ Power Rail, and having submitted a most compelling offer, RJ Power was subsequently awarded the points heating, signalling and general power supplies contract works with a commencement date of August 2016.
RJ Power was also awarded an electrical enabling works package in preparation for the main improvement works. These works included:
The awarded sub-contract package was RJ Power’s largest contract to date and was testament to the quality of the bid submitted, which required RJ Power to supply all access and operative accreditation for below ground cabling installation and cable installation plant. The bid included a carefully thought through methodology in respect of the off-loading and lifting of all fixed equipment into final position on site and provision of part time on site management for the two months leading up to construction, to support effective and collaborative planning and co-ordination with the PCL, to achieve a series of milestones and to ensure that the exact start date for the fixed plant installation was met. It was also a requirement for the team to supply full time site management for the duration of the on site works up to the acceptance date from Crossrail and for energisation of all services installed.
RJ Power’s contracted electrical power scope of works for the project consisted of the following extensive deliverables:
Installation of HV and LV substation, cabling and switchgear consisting of:
Installation of 650V signalling power system including:
Installation of points heating equipment, consisting of:
Challenges and Solutions
Complex project interfacing
RJ Power faced challenges with the timescale of this project due to the number of different project interfaces during the course of these works. With the works being of a multi-disciplinary nature and with multiple contractors needing to negotiate access arrangements, RJ Power’s team needed to be extremely flexible and work collaboratively when approaching and delivering key milestones in their programme.
Careful logistical management was also needed as multiple electrical assets were being supplied by RJ Power. All deliveries were pre-planned in accordance with a Traffic Management Plan. All vehicles accessing the site had to be Crossrail compliant, and in line with the directives given by Traffic Marshals. All plant/pedestrian interfaces had to be managed around the nominated site storage area, with segregated walking zones provided and Banksman present during the transportation and lifting into position of all materials for the works.
As a result of some of the client programme delays, RJ Power was presented with a number of resourcing conflictions due to requirements on concurrent projects. Close communication and liaison between the project teams was vital in highlighting any potential risks and providing a safe and comprehensive solution. RJ Power’s role as team player with a collaborative working approach was commended by VFL Head of Commercial Andy Gardiner, who praised the project team for their fantastic achievement in helping to achieve 500,000 project delivery hours without any incidents or accidents following completion of a major blockade at the end of 2016.
Installing a rare joint
As part of this complex E&P scope, RJ Power was also asked to complete a unique and rare joint at Ilford Depot.
The existing cable (25kV) was installed in 1959 and was a Mass Impregnated Non Draining cable. RJ Power was asked to joint this to a modern XLPE cable, using a unique joint that needed commissioning by specialist Tyco in Germany.
With an 8-10 week lead-time on the joint, careful planning was needed. The residual risk being that if the joint, on arrival from Germany, did not fit the two separate cables or was unsuitable, the programme would have been severely disrupted.
RJ Power engaged its procurement and logistics team, which managed the purchase and shipping of the joint in close liaison with Tyco, to enable seamless delivery of this specialist joint.
The company’s skilled jointers then took over to deliver this high-risk element of the works, successfully completing them and delivering a first class solution, the sort of which RJ Power’s experienced electrical team thrives upon.
