Scope
Description
GWR is seeking to establish a Framework Agreement for the delivery of construction and infrastructure works across its property and depot estates. The framework will cover a broad range of project types including minor building works, refurbishments, renewals, upgrades, and new construction at stations, depots, and operational facilities.
The framework will be divided into three lots:
Lot 1 - Minor Works: General building, refurbishment, and maintenance.
Lot 2 - Stations Major Works: Station upgrade and construction projects.
Lot 3 - Depot Works: Building and infrastructure improvements at depot sites
The framework will operate for a period of 3 years with an optional 1-year extension (3 + 1 years) and will be structured as an open framework, allowing supplier refresh during its lifetime.
Works will be called off under adapted JCT contract forms (Minor Works, Intermediate with Contractor's Design, or Design & Build, as applicable) and will be awarded via mini-competitions.
All works must be delivered to the required safety, quality, and environmental standards, ensuring minimal disruption to operational sites and alignment with the contracting authority's sustainability objectives.

The highest-scoring suppliers will be appointed to the framework for a period of 3 years with an optional 1-year extension (3 + 1 years).
The framework will operate on an open basis, allowing new suppliers to be added during its term to maintain competitiveness and capability.
Call-Off Tenders:
Once appointed, framework suppliers will be invited to compete for individual projects through mini-competitions.
Each mini-competition will include a defined scope, pricing schedule, and specific evaluation criteria.
Evaluation weightings for Technical and Commercial submissions will vary depending on the complexity and nature of the project, typically within the following ranges:
