TFL – BARKING RIVERSIDE EXTENSION

Disciplines: Project Management, Project  Engineering, Construction Management

Barking Riverside extension includes 4.5km of new track, a viaduct and stations – it  is one of several transport measures designed to serve the emerging development  area at Barking.

At an early stage, TfL's delivery team recognised the challenges such a complex  programme presented and engaged with its Integrator Framework to ensure the  right support was available. Following a procurement exercise, Lendlease and SRC Infrastructure was asked to provide Project, Engineering and Construction Management partner consultancy services.


The offer was developed in line with ICE's Project 13 guidelines and philosophy The team, embedded within TfL has been seamlessly supporting the delivery of the project for over a year, augmenting capability and capacity in many ways.

TFL – TECHNOLOGY AND DATA

Disciplines: Project Engineering, Project  Management, CAD technology management

TfL is at the forefront of using WIFI to leverage passenger movement metrics across it’s network SRC Infrastructure collaborated with TfL Technology and Data to create WIFI link node models for over 250 stations.

WIFI utilisation metrics were built to understand and calculate the traffic/number of passengers between WIFI nodes This quantification of peoples’ movements will enable advertisers and TfL to assess more accurately the value of their fixed advertising assets.


SRC Infrastructure led the research, development and finalisation of the required mathematical models for locating communications and systems equipment within underground stations in support of WIFI roll out. 

Key achievements include:

  • The development of link-node models for circa 250 stations.

  • Defining the entry and exit points, where appropriate and link the nodes  between them within the stations.

TFL – DEEP TUBE UPGRADE CRMS FEASIBILITY

Disciplines: Mechanical, electrical, signalling engineering

SRC Infrastructure was commissioned to review the feasibility of potential cable route management solutions between locations for TfL’s Deep Tube Upgrade Programme (The key project objective was to identify the most cost effective models.

5 stations were reviewed Cockfosters Station, Oakwood Station, Southgate Station, Arnos Grove Station, Bounds Green Station

Key recommendations:

  • Tunnel sections and Stations are crowded with existing system therefore Cable tunnel chambers could provide possibility of new CRMS installation.

  • A concomitant Anchor post system may alleviate confined space issues in many cases. 

  • TT wires and redundant cables need to be removed to free space for new CRMS Impact of this work needs to be  discussed and planned in detail.

Key considerations:

  • Costs and Schedule

  • Maintainability

  • Operational Impact

  • Buildability and Logistics

  • Interface with existing infrastructure

  • Heritage and 3rd Party stakeholders

LONDON OVERGROUND – TRAMS

Her Majesty’s Government Rail Accident Investigation Branch (RAIB) carried out a  13-month investigation into the causes of the Croydon tram crash which killed seven  people and injured dozens more. RAIB made 15 recommendations. A number of  these require new processes and controls and others require modifications,  improvements or new systems infrastructure solutions.

 

SRC Infrastructure led the engineering development, testing, and coordination and roll-out for these changes.

This is the first project on UK trams that integrates existing systems with new as a  means to improve the safety of trams.

Examples of these innovative solutions:

  • Prototyping a Physical Prevention of Over-speeding System (PPOS) system,

  • Prototyping and integration of a driver awareness system already used in the road haulage industry.

  • Signage and software integration to improve visual sighting for drivers.

STEPNEY GREEN STATION SIGNALLING EQUIPMENT ROOM DESIGN​

Disciplines: Civil / Structural, Electrical, Mechanical, Signalling, Drainage

The Stepney Green fire-rated enclosure commission was a multidisciplinary project involving civil/ structural, electrical, and mechanical engineering.

 

The scope was to design a one-hour fire rated enclosure around existing operational and safety critical systems; including signalling equipment. The design  had to be compatible within the tight space constraints at Stepney Green Station,  as well as satisfy LU standards of fire resistance integrity and insulation to the  structure.

SRC Infrastructure delivered the design and compliance documentation to time, and a high standard by working within a rigorous assurance  regime. This enabled construction to proceed to schedule.

SRC Infrastructure also took on additional works  after designs had been agreed, to enhance the  ventilation and lighting arrangements within the enclosure. SRC Infrastructure met the challenge and incorporated changes into the designs allowing construction to commence at short  notice.

METROPOLITAN LINE EXTENSION PROGRAMME – CONCEPT DESIGN

Disciplines: Cable Route Design,  Systems Engineering

SRC Infrastructure developed a cable route concept design for the Metropolitan Line Extension Programme.

 

The project was an unusual challenge as there was no existing railway running for a significant part of the route. SRC Infrastructure’s team had to derive requirements from an existing power study, from indicative layout drawings and our own  understanding of what the ATC solution for this area might be.

The scope of the commission included requirements definition, standards analysis, risk analysis and production of CDS and approval of Form A submissions. The Concept Design CRMS had to carry 11kV, Pilot, radiating cable, miscellaneous LU, and LU  signalling, communications and power cables.

Key achievements:

  • The SRC Infrastructure team liaised with all engineering stakeholders (LU and NR) to achieve consensus and approval

  • Leveraging our expertise of the probable signalling system to add a very  significant level of knowledge to the Client team and produce a submission which  far exceeded expectations

JUBILEE AND NORTHERN LINES

CABLE ROUTE MANAGEMENT DESIGN & ENGINEERING TEAM​

Disciplines: CRMS, Civils & Structural Engineering

SRC Infrastructure was commissioned to design and assure proposed CRMS routes on the  Jubilee and Northern Line’s Upgrade Programme. The scope was to manage, design and assure the Cable Route Management Systems (CRMS) for the power, signalling and communications cables.

Key activities included:

  • the design of over track crossing arrangements

  • new post routes

  • extension of the existing post routes

  • earthing and bonding arrangements.

 

During this project SRC Infrastructure, with London Underground, developed a set of generic template CRMS solutions which are now issued as approved “best practice” designs.

NEASDEN DEPOT - MULTI-DISCIPLINARY INFRASTRUCTURE DESIGNS

Disciplines: Civil / Structural, Electrical, Fire, LV & HV Power, Mechanical, Signalling

Neasden Depot is the largest depot on London Underground’s network. SRC  Infrastructure undertook a number of inter-dependent design commissions at Neasden depot, including:

  • The complete new signalling & LV power cable routes (CRMS) throughout the depot

  • The new lighting & earthing arrangement on the main depot bridge

  • The Transformer Room and associated LVAC Switch room inside the existing Switch  room complex.

The projects were programme-critical and had a number of challenges. Access for survey and for installation was significantly constrained as few  possessions were available.

SRC Infrastructure developed and achieved approval of an innovative passive  ventilation system that had not been used on TfL infrastructure before. This required  approval by external regulatory bodies.

CROSSRAIL/ LUCT - DETAILED DESIGN OF BOND STREET CONTROL ROOM & NON-PUBLIC AREAS

Disciplines: Civil / Structural, Electrical, Mechanical, Signalling, C&I, Drainage, Communications, Premises

SRC Infrastructure was commissioned to provide multi-disciplinary, integrated designs; from outline to construction. These designs detailed the new Station Operations Room, Communications Equipment Room and other non-public areas (Locker rooms  etc) to serve both the London Underground and the Crossrail sections of the station.

LONDON UNDERGROUND - RETAIL

Disciplines: Programme Management, Project Management, Project Engineering, Commercial & Cost Management,  Mentorship

SRC Infrastructure, in partnership with Lendlease Consulting, was engaged by London  Underground to provide programme delivery capability for the Retail Enhancements  Programme – taking 12 LU stations and 5 Crossrail stations through feasibility and  concept design, and across Gate 3.

Key Achievements:

Th team optimised the programme to achieve early delivery and cost savings for Lot 1.  This reduced the schedule by 6 months, and lowered the estimate at completion. This was enabled by:

  • Challenging pre-existing pathway products and assumed timescales,

  • Creating a fully-integrated master programme,

  • Developing a tranche wide resource planning framework that enhanced the pre- existing organisational capabilities of the LU team,

  • Technical and stakeholder workshops to produce base requirements standards –  including the minimum technical parameters for different configurations of commercial units.

LONDON UNDERGROUND – SYSTEMS RENEWALS AT BARBICAN STATION

Disciplines: Civil / Structural, Electrical, Mechanical, Signalling, C&I, Drainage, Communications, Premises

SRC Infrastructure supported the Systems Programme within the London Underground  Renewals Portfolio through a review of the Barbican Refurbishment Project. The Barbican Refurbishment Project is a multidisciplinary scheme (Fire, Comms, Civils, Premises,  Mechanical & Electrical). It addresses asset obsolescence, asset safety, legal compliance &  LU compliance.

Key Findings:

  • The engineering & design deliverables did not follow TfL’s Pathway, resulting in misalignment with the PRS.

  • The original Scope of Works was not complete or baselined. This was because the  interfaces with other programmes (including Crossrail and 4LM) had not been formally  defined and agreed.

  • The design activities were not aligned with an accepted D&B Procurement Strategy.

  • The Project was under resourced, which was putting the programme at risk.

Key Recommendations:

  • That the project should separate out independent and enabling works packages. This would ensure that each can meet the Stage Gate 2/3 milestones, and bring forward the start on site date for these activities, without compromising time, cost, quality or safety.
