CASE STUDIES

CONSTRUCTION MANAGEMENT

 

SSL CEP Construction Management and Engineering

SRC staff embedded within London Underground’s Capability Enhancement Project (CEP) played a key role in delivering the installation of 38km of power cabling between Bow Road and Stepney Green on the District Line. The works included the installation of 83 turning units, new concrete bases, cable stiles and the delivery of signalling location cabinets and platforms.

 

Due to the space constraints within the tunnel sections in this area, the new CRMS had to be mounted 3.5m above ground level. This meant that installing cable within normal engineering hours would have proved extremely problematic. To overcome this challenge, the team developed a new system utilising a Road Rail Vehicle and man riding platform to allow operatives to work safely at height.

 

The process of providing a specialist plant arrangement was a key innovation which enabled the cable routes to be installed successfully. The processes of plant approval and logistical planning for this item of work were complex, but ultimately enabled this large volume of work to be completed within a 52hr possession window.

 

VLU SCC Installation Management

SRC provided London Underground Ltd. with Project Management and a team of Project Engineers to carry out the specification, installation, testing and commissioning works for a new Service Control Centre at Northumberland Park Depot to serve the Victoria Line.

 

SRC managed the delivery of the build for this new building, and the specification and installation of the control systems. SRC’s expertise in signalling, power and electrical design and its extensive knowledge of LU infrastructure ensured that the design process took these factors into consideration.

An understanding of human-centred design was also important to ensure that the systems and equipment provided were suitable for their future operators. SRC’s collaborative approach enabled all parties involved in the contract to understand what the works involved. A thorough knowledge of the existing systems and equipment enabled the interfaces with new systems to be managed successfully, enabling cost and time savings to be made and the creation of a high quality finished product.

 

Bond Street Station - Survey and Site Management

SRC was commissioned by Atkins to fulfil the role of Principal Contractor for this project. This involved managing and coordinating a number of surveys and operations to assess and monitor the effects of the interface works for the new sub-surface ticket hall on the existing station’s structure. These involved digging trial pits and deep boreholes.

 

Further works were carried out at various trackside and station locations, including air velocity surveys, exposing tunnel ring segments at numerous locations and installation of monitoring equipment. Areas were then made good to ensure they were in keeping with the existing station finishes. The commission involved the supervision of site works, undertaking safety audits, review and approval of method statements and safety management.

The challenge involved progressing site works and delivering the project on time while also keeping the busy station operating as normal.
