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
Version 5.0 – CONFIDENTIAL

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
Version 5.0 – CONFIDENTIAL
30/11/2017 Wales & Borders Rail Service and South Wales Metro 1

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
Version 5.0 – CONFIDENTIAL
30/11/2017 Wales & Borders Rail Service and South Wales Metro 1

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.
