Engineering and Architectural Assurance of Building and Civil Engineering Works
|Publication Date:||5 September 2020|
Types of Assets
This business process applies to these types of assets:
NOTE 1: These assets are otherwise known as B&C infrastructure and are defined in NR/L1/CIV/032 (Structures and Tunnels), NR/L2/CIV/086 (Earthworks), NR/L2/CIV/005 (Drainage), NR/L3/CIV/006 (Buildings) and NR/L2/CIV/191 (Mining),
c) tunnels and mines (mineral workings);
f) building services;
g) civil and building type elements or components of other assets.
NOTE 2: The types of assets listed might include architectural aspects.
Types of Works
This business process applies to these types of proposed or actual Works when undertaken on buildings and civils infrastructure that is owned, or is to be owned, by Network Rail:
d) repair works unless specified otherwise by the Route Asset Manager;
e) emergency works;
f) temporary works:
1) to facilitate the construction of permanent Works or staged construction;
2) to provide access for examination and inspection.
NOTE 1: Temporary Works could have the same impact on the infrastructure as permanent Works. NOTE 2: Permanent Works and Temporary Works designs shall account for Temporary Conditions.
External Party Assets
This business process applies to External Party Buildings and Civils infrastructure where either:
a) Works are undertaken by Network Rail; or
b) the External Party infrastructure is:
1) on, over, under or adjacent to Network Rail's infrastructure; and
2) the External Party does not have an equivalent engineering assurance procedure to NR/L2/CIV/003 for those Works.
NOTE 1: This business process applies to External Party works managed through the Landlord's Consent process.
NOTE 2: The procedure defined in the Design Manual for Roads and Bridges (DMRB) 'Technical Approval of Highway Structures' (BD 2) is considered to be equivalent where amended to include railway aspects from F001 and F002.
Network Rail has no power to enforce the requirements of this business process on Works undertaken on External Party infrastructure which lies entirely outside Network Rail's property boundary except through legal agreement.
NOTE 3: This is the case whether or not such Works could affect railway operations.
For such Works, reasonable endeavours can be followed to apply the requirements of this business process or to obtain confirmation from the External Party that an equivalent procedure to that shown in 5 is in place.
NOTE 4: Where an External Party decides to adopt the requirements of this business process, it is acceptable to use modified versions of the forms associated with this business process. For example, not following references to GRIP. Application
This business process applies to Network Rail and non-Network Rail personnel involved in the remitting, design, design approval and taking into use of Buildings and Civils infrastructure.
This business process does not apply to:
a) consents or approvals from bodies outside Network Rail including:
1) regulatory and statutory authorities;
2) planning, listed building and conservation authorities;
3) environmental agencies;
4) land and property owners or leaseholders;
5) statutory undertakers and other public services and utilities owners.
b) obtaining approvals for the New Roads and Street Works Act;
c) obtaining approval from other Network Rail engineering disciplines for the equipment carried by Equipment Support Structures or for the performance of that equipment;
NOTE: For Example, signal sighting and reduced clearances.
d) assessments of structures.
This business process sets out:
a) the engineering and architectural assurance of Works to Building and Civil Engineering infrastructure; and
b) Entry into (Operational) Service (EIS) requirements for such Works. The engineering and architectural assurance process is a consistent method of verifying that designs:
1) meet client, project and stakeholder requirements;
2) are suitable in terms of:
Design is critical to controlling business and safety risk throughout the asset lifecycle.
The processes described in this document support the broader engineering assurance processes detailed in NR/L2/INI/02009 and NR/L2/INI/P3M/101.
