Requirements for Cable and Route Design Submissions
Issue 2.1, Feb 2009 · FTN D&D specs & typical drawings
Defines the format and minimum contents of an FTN cable and route design submission (design pack): title page, SLD, schedules, splicing diagram, BoQ, concessions, Form C1. Used by designers assembling a pack and by checkers reviewing one.
Clause map — what each clause deals with
| 1 | Introduction | Background to the FTN programme and how survey output feeds the detailed design. |
| 2 | Scope | Defines format and minimum inclusions of a submission; does not say how to design. |
| 3 | Abbreviations | Abbreviations used (ADM, ATEH, BoQ, BT, CRE, DRE, MLOR, PDR, PMux, RC, RR, SLD, STM, WHD, ZHLS). |
| 4 | Glossary | Defines the design roles (Designer, Checker, Reviewer, Approver), submission, copper section and half section, BT/RC vs rail return, parallelism, red bond, touch potential, tunnel repeater. |
| 5 | General | Design submissions per contiguous line of route between nodes, one approved design per section, adjoining design references, page numbering, hard and soft copy format. |
| 6 | The Content of Design Submissions | The master list of sections every submission must contain, and Network Rail's right to ask for more detail. |
| 6.1 | Title Page | Title page fields: line of route, limits by node short code, DS-(XXXX)-(YYYY) reference with alphabetical ordering, issue/draft numbering rules, names and signatures. |
| 6.2 | Contents Page | Each section listed with page number, preferred order. |
| 6.3 | Introduction and Précis | Scene-setting section: general information (nodes, distances, electrification, cable type, survey date), existing route characteristics, design summary (route and cable types, diversity, hazards, fragile cables). |
| 6.4 | Design Assumptions | Record any assumptions or decisions beyond the standard design rules. |
| 6.5 | Location Maps | Maps from UK level down to 1:25,000 detail showing each node and local features. |
| 6.6 | Straight Line Drawing | Purpose and file format of the SLD, the full list of permanent way, signalling, electrification, existing and proposed features to show, colours and title block. |
| 6.7 | Transmission Design Information | Précis of the transmission design, its line diagram and document references, plus LPDO supplementary info. |
| 6.8 | PDR and Engineering Clearance | Status of property development rights approval and the current MLOR spreadsheet. |
| 6.9 | Design Concessions | Every departure from the cable and route specs needs a concession per QM/WI/028; include all applications and a status summary. |
| 6.10 | Survey notes | Include the SP/FTN(SU)/001 survey notes with a line of route drawing. |
| 6.11 | Photographs | Photo format, unique identification, copyright, and the guide list of features that should be photographed. |
| 6.12 | Bill of Quantities | BoQ split into free-issue and constructor-supplied items, correlating with the survey; designer owns accuracy. |
| 6.13 | Copper Details | Copper cable schedule fields (meterage, pairs, conductor, sheath, lengths, allowances), distribution cabinet schedule (type, location, handrails, FTE, bonding, civils, services, verticals), copper joint locations. |
| 6.14 | Fibre Cable Details | Fibre main and spur cable schedules with allowances, fibre joint schedule (ID, closure, kits, type, housing, location), termination schedule, sheath gap schedule, node MDF details. |
| 6.15 | Fibre Splicing Diagram | What the splicing diagram must show: cable/joint/termination IDs, joint types incl. backsplice, tube and fibre allocations, distances, drawing block, loss budget, network and user designations. |
| 6.16 | Screening Conductor Details | Screening conductor length schedule with allowance and size, joint locations and earth tap points, earth schedule (existing or new). |
| 6.17 | Physical Diversity Requirements | Per-node diversity diagram: node reference, track layout, all crossing points, cable routing and entries, rings supported. |
| 6.18 | Structural schedule | Schedule of retaining walls, platforms, manholes, UTXs, crossings, URXs with location and Form A&B flag. |
| 6.19 | Manhole schedules | Per-manhole developed-wall diagram showing nearest track, all entries, and pipe allocation (FTN, blocked, spare). |
| 6.20 | Designer's Risk Assessments | Site-specific risks not covered by generic assessments. |
| 6.21 | Tunnel Information (Cable Provision) | Complete the Appendix B pro-forma for each tunnel. |
| 6.22 | Certificate of Compliance (Design Requirements): Form C1 | Form C1 signed by the CRE confirming the design is compliant, checked and approved. |
| 7 | Reference Documentation | Lists SP/FTN(SU)/001, SP/FTN(D&D)/004, 005, 006, 008, 009, 016, 017. |
| App A | Design Submission Front Page | Title page template (image only in the text extract). |
| App B | Tunnel Template | Tunnel information pro-forma: tunnel details, bores, length, tracks, nearby tunnels, joint distances and IDs at each end, BTS proximity, LPDO and radio design sign-off. |
