1. Introduction

1.1 This document sets out submission requirements for the CVL Concept Design.

1.2 It supersedes the earlier version v4.0 issued on the 15th September 2017.

1.3 Appendix A sets out the TfW Plan of Works which details the seven stages

of project development from output requirements through to closeout. These

are referenced throughout this document. Each of the stages has a number of

deliverables associated with the successful delivery and closure of a design

development stage, once a TfW review of the required outputs has been

successfully completed and accepted.

1.4 The CVL designs will be submitted in three stages:

a) CVL Concept Design (as defined in this document):

You submitted completed CVL Concept Design documentation including

costing templates which set out an Outline Target Price (Section 2

below). TfW agreed with Bidders the Outline Target Price and

associated Optimism Bias and ‘froze’ the CVL Concept Design on 30th

June 2017.

b) Draft ITSFT

There are further elements of CVL Concept Design required in Final

Tenders and these were highlighted in draft form in the Draft ITSFT.

Responses to the Draft ITSFT were dialogued before issue of the ITSFT.

These elements are not under ‘change control’.

c) ITSFT (late 2017):

Bidders will submit final versions of the ITSFT products in their Final

Tender. Until submission of Final Tenders, Bidders can ask to change the

CVL Concept Design but this is subject to agreement with the Authority.

The full set of 20 CVL Concept Design products for the CVL Concept

Design shall be submitted in your Final Tender.

Changing after ‘freeze’

1.5 Once frozen, the CVL Concept Design including Outline Target Price could

only be changed by agreement with the Authority. Change has, however, been

permitted. Bidders have been able to modify the CVL Concept Design and

associated Outline Target Price, with Authority approval, once every six weeks

until Final Tenders are submitted. The Authority could take up to two weeks

to provide feedback on design maturity and Outline Target Price, so

recommended that any substantial changes were made early. Further details of

the change control process are contained within the document entitled "Core

Valley Lines – CVL Concept Design – Change Control Process", v5.0 dated

25th September 2017.

1.6 The Outline Target Price at the time of submission of the Final Tender must be

affordable in terms of the CVL Capital Budget set out in Volume 1 of the

ITFST. It was permitted for the Outline Target Price to exceed the CVL Capital



2

Budget so long as the CVL Concept Design is affordable by the time Final

Tenders are submitted.

1.7 The Authority reserved the right to modify the requirements for CVL Concept

Design during dialogue until issue of the ITSFT.

11

Appendix C: CVL Concept Design Costing Templates Parameters

1.1 Detailed below is the basis of pricing for the CVL Concept Design Costing

Templates for the CVL Capital Works to be used by Bidders. This will assist the

Authority in ensuring a consistent approach to pricing across all Bidders.

1.2 These notes contained within this Appendix sets out the parameters of the

following:

a) Cost of dealing with Statutory Authority apparatus;

b) Betterment of structures / highway interfaces;

c) Land costs;

d) Works to upgrade the existing asset condition / works to structures not

affected by electrification;

e) Works at stations;

f) Park and Ride facilities;

g) Third Party costs;

h) Network Rail / TOC / FOC costs;

i) Optimism Bias;

j) Inflation;

k) VAT, and

l) Utility relocation for on-street running in extensions.

1.3 Whilst it is the Authority’s intention to work with the ODP to refine the

project costs prior to the establishment of the Agreed Target Price, the

Authority requires at tender stage a high degree of confidence that the

proposed solution is deliverable within the capital works budget of [redacted]

million. To this end, it is the Authority’s intention that exclusions from the

pricing are kept to an absolute minimum. Unless expressly stated in this

Appendix, it is assumed that the prices submitted by the Bidders shall represent

the full cost of delivering the proposed solutions.

Statutory Authority apparatus

1.4 The Authority has issued to Bidders information relating to existing utilities at

over / under-bridges. Whilst it is accepted that the timescales will not allow

Bidders to obtain budget prices from the relevant utility company, the

information is deemed sufficient to enable Bidders to submit budget prices

based on their own experience.

1.5 Where additional utility network connections are proposed in the Bidder

solutions, appropriate allowance is to be made in the cost templates.

Betterment works at structures / highways interfaces



2

12

1.6 Where structures are being reconstructed in order to achieve gauge clearance,

Bidders are to assume that a like for like structure is to be provided, provided

that the existing structure is compliant with the relevant design standards

(DMRB). The cost of upgrading non-compliant structures to meet the

requirements of DMRB shall be included in the cost templates.

1.7 Betterment works required as a consequence of the closure of level crossings

are to be included in the cost templates.

Land costs

1.8 Bidder solutions may require the acquisition of additional land beyond the

boundaries identified within the ownership of either Network Rail or Welsh

Government.

1.9 The cost associated with additional land acquisition is to be included in the cost

templates.

Asset condition

1.10 It is acknowledged by the Authority that information relating to the condition of

the existing assets is limited and that considerable work will be undertaken

during the Design and Discovery phase to assimilate information relating to the

existing assets.

1.11 Bidders are to include all costs associated with transforming the existing assets

in order to deliver their proposed solution. The existing assets and the

transformation works are to be fully compliant with the appropriate Railway

Group standards, ROGS or any such derogations in place as agreed with the

Regulators.

1.12 Bidders are not required to include allowances for general upgrades to the

existing asset, for example, structural repairs to bridges unaffected by the

works. Such works will be considered under the scope of the Operation,

Maintenance and Renewals works [subject to final confirmation at ITSFT].

Stations

1.13 Bidders shall identify in the ITSFT CVL Stations Schedule (Appendix M) the

works which shall be funded from the capital budget and those works to be

funded through the Railway Operational Budget or Residual Value Mechanism.

The cost of capital works proposed at each station shall be included in the cost

templates.

Park and Ride facilities

1.14 Where Bidders are proposing to utilise the capital works budget to enable the

construction of park and ride facilities, these costs shall be included in the cost

templates.

Third Party Costs

1.15 Bidders are to include for all costs relating to third party agreements, including

all IDP costs including liaison and management costs. Such costs are to be



3

13

included in the relevant section of the cost template for the ODP Programme

Manager and Railway Group Elements.

1.16 This relates to third parties including, inter alia, ORR, Network Rail, Local

Authorities, Natural Resources Wales, CADW, DNO, Statutory Authorities

and Landowners.

Network Rail / Possession Costs

1.17 In relation to works outside of the CVL which are not included in the asset

transfer, Bidders are to include for all costs relating to Network Rail asset

protection, Network Rail project management, Network change, depot change,

station change, TOC / FOC compensation, possession management and charges.

1.18 In relation to works within the CVL, allowances shall be made for the charges

set out in 1.17 above in relation to works and investigations to be undertaken in

advance of the asset transfer.

1.19 Furthermore, for the period following the commencement of rail operations by

the ODP and the transfer of the CVL assets to Welsh Government, the ODP

shall determine whether the ODP and IDPs will incur charges relating to asset

protection, TOC / FOC compensation and possession charges. Any such costs

and charges shall be included in the cost templates.

Optimism Bias

1.20 It is the Authority’s intention to apply a consistent level of optimism bias across

all bidders. It is proposed that works to the Core Valley Lines will attract a

minimum optimism bias of 44%, consistent with the approach taken to the

development of the business case. Bidders may apply a higher percentage based

on their assessment of risk and pricing confidence.

1.21 Non-CVL works will attract a minimum optimism bias of 55%. Bidders may

apply a higher percentage based on their assessment of risk and pricing

confidence.

1.22 Costed options will attract an optimism bias of 66%.

Inflation

1.23 The base date for the pricing of the Infrastructure Development Capital Works

is Q2 2017. Bidders are required to include appropriate allowance for future

price escalation.

1.24 For the purpose of benchmarking the Bidder capital works estimates, the

Authority intends to calculate the impact of future price escalation based on the

RPI forecasts in the following published indices:

1.25 2018/19 to 2034/35: DfT WebTAG databook March 2017 – Table A5.3.1

1.26 The annual percentage values for future price escalation derived from the above

index are as set out in the table below:

1.27 The above percentage values are to be fixed in the cost templates. Bidders may

choose to submit adjustment values (positive or negative) to the predetermined

RPI values.

VAT

1.28 The Capital Works budget includes VAT at 20% and Bidders are to assume that

VAT is to be charged on all works and services.

Costed Options

1.29 The cost of relocating existing utilities is to be met by TfW if the Bidder

proposes on-street running to deliver any of the extensions.
