The Brief

Project Lightning - At the start of 2016 we were invited to be one of Virgin Media’s strategic planning partners to assist with their single biggest growth programme to date, entitled Project Lightning. This is an ongoing £3bn investment by Virgin to connect an additional four million homes and businesses to their ultrafast fibre optic network.

The Result

Going on to survey and design more than 500,000 premises and upwards of 750km of trunk route over the next 2 years, we have always delivered on time and on budget. BDS have appeared at the top of the Virgin Media Quality Assessment tables since planning reviews were introduced in 2017 and this is testament to our commitment to providing a consistently accurate deliverable.

The Process

Working closely with the Build Delivery team we assisted Virgin Media to successfully trial their first few Fibre to the Premise (FttP) areas. Whilst doing this we helped to devise drawing formats, templates and processes, many of which were adopted into the project technical specification and are still being used as standards across the Lightning Project. After design completion and approval, we would then provide a compliant design onto G-Comms, VM’s corporate GIS platform.

The Brief

Smallworld Project - From a standing start in August 2015 to completion in January 2016 we were given the daunting task of surveying and designing 100,000 premises in just 5 months for Virgin Medias ‘Smallworld’ franchise in the north-west of England and west of Scotland.

The Result

Reaching the necessary 80,000 homes planned by December 2015, BDS ultimately delivered over 110,000 by project completion in January 2016.

The Process

The network architecture was a hybrid fibre / co-ax system and there were significant areas of existing stranded plant that were to be re-used. We set up ‘rodding and roping’ teams in addition to our standard survey teams in order to properly audit the existing infrastructure prior to design. By spending more time and effort on surveying upfront we were able to plan and manage the timescales and the fundamental design with no surprises to the delivery!

The Brief

FTN Route Survey & Design - Trading as NDC Consultants, BDS was contracted by Network Rail to undertake a national survey of the existing cable and cable route, and to produce detailed designs for the new telecoms network.

The Result

BDS carried out in excess of 9,000km of FTN route surveys and delivered over 1,500 design packages during our 7 years on the project.

The Process

Our survey teams accurately recorded the position of all relevant line side features, which included GPS co-ordinates for line side telephones, cabinets, transmission and radio sites, bridges, tunnels and access points, together with thousands of photographs.

Back in the office, our bespoke site data acquisition and management system was used to efficiently collate and structure this data. BDS planning engineers then produced comprehensive and accurate scope of work packs to meet Network Rail's exacting design specification. This included a line drawing showing the position of the new works including proposed new routes, joint bays, under track crossings and distribution cabinets, etc, together with a Bill of Quantities. This completed planning package was then used by Network Rail to contract the construction and installation works.

The Brief

FTN H&S File Production - Trading as NDC Consultants, BDS held a framework contract with Murphy Group to complete the As-Built documentation and Health and Safety files for all their FTN cable and cable route works.

The Result

BDS provided over 700 CDM compliant Health and Safety files for Murphys, documenting over 3,500km worth of route-works.

The Process

Upon completion of all civil and cabling works our specialist team carried out an As-Built survey to verify the completed work. The survey team collected information to meet with Network Rail’s requirements including Photographs, GPS Co-ordinates, installed Cable sheath coding and Joint/Cabinet details.

The information was returned to the office and was collated into a Network Rail approved database, which was used to complete red line drawings. These documents were then added to the Network Rail standard Health and Safety file along with documentation such as Cable Test results, Work Package Plans, COSHH and Risk Assessments, etc. This enabled Network Rail to maintain and operate the newly installed Fixed Telecoms and GSM-R networks.

The Brief

FTN Circuit Migration Works - In order to get maximum benefit from the new Fixed Telecommunications Network, Network Rail faced the enormous task of transferring existing live operational telecoms circuits onto the newly installed FTN cables and systems.

The Result

BDS successfully completed over 600 surveys and designs at various relay rooms and signal boxes throughout the UK.

The Process

Trading as NDC Consultants, BDS undertook detailed surveys and produced designs for proposed inter-connects to the new network at a selection of Network Rail’s critical relay rooms and signal boxes, with the aim of meeting the technical requirements for migration in the most cost-effective way.

Working with Network Rail we produced a standard format for the design which was both compact and simple, yet sufficiently detailed to allow Network Rail’s principal contractor to price, construct and install the final system.
