Official UK procurement notice
AP25177 - Mechanical Engineering Framework
Authority: Arc Property Services Partnership Limited (Public body)
What is being bought
Published requirement descriptionArc Property Services Partnership Limited (the “Client”) intends to procure a single-supplier framework agreement for the provision of a comprehensive range of mechanical engineering works acrossthe operational estate that it manages on behalf of Nottinghamshire County Council (NCC).
The Framework will provide access to a suitably qualified and experienced Contractor capable of delivering planned works on an as-required basis. The services will support the Client’s construction, maintenance, and asset management activities across multiple sites. The scope of services to be delivered under the Framework includes, but is not limited to:
- Plumbing and water systems: installation, maintenance and repair of hot and cold-water services, drainage systems, sanitaryware, thermostatic mixing valves (TMVs), unvented systems, and water hygiene activities.
- Heating and mechanical plant: servicing, maintenance and installation of heating systems (including gas, oil, electric and renewable technologies), distribution systems, pressurisation units, and associated plant.
- Fuel, gas and energy infrastructure: installation and maintenance of fuel storage systems, gas installations, associated safety systems, detection equipment, and energy infrastructure.
- Controls and building management systems (BMS/BEMS): provision, maintenance and modification of controls, sensors, panels, valves and automation systems used to monitor and manage mechanical services.
- Installation, alteration and minor works: new installations, replacement works, adaptations to existing pipework systems, removal of redundant systems (including dead legs), strip-out works, and associated making-good of building fabric.
- Testing, commissioning and compliance: full testing, commissioning and certification of systems, including statutory compliance, earthing and bonding where applicable, and handover documentation.
The Framework will operate under the NEC4 Framework Contract and will enable the Client to commission individual call-off contracts for specific projects or service requirements. Call-off contracts will be arranged via quotation utilising the prices set within the Framework Commercial model.
The Framework will cover a geographically dispersed estate, with works located across Nottinghamshire (main area), Derbyshire, South Yorkshire, and Leicestershire.
The anticipated initial term of the Framework is two (2) years, with options to extend for a further two (2) years plus one (1) year (2+2+1), giving a maximum potential duration of five (5) years. The 5 years framework is to be utilised to coincide with the current end of Arc Partnership's arrangement with Nottinghamshire County Council.
The total value of the Framework over its full term is £13,200,000 (inclusive of VAT), however there is no guarantee as to the value or volume of work provided.
The procurement will be conducted in accordance with the Procurement Act 2023 using a competitive flexible procedure, comprising a two-stage process:
- Stage 1 - Selection Criteria - The Bidder must meet or exceed the selection criteria based on the required qualifications and experience to confirm that they have the correct capacity, competency and capability to meet the framework requirements. Bidders who receive PASS marks from the selection criteria will then have their selection criteria questions evaluated and the 4 highest scoring bidders will move to stage 2.
- Stage 2 - Award Criteria - The remaining Bidders will be asked a series of quality questions and shall provide prices within a commercial model. These will be assessed against a set criteria based on a 70% quality / 30% price evaluation weighting. The highest scoring Bidder will be deemed to have provided the Most Advantageous Tender (MAT) and will be awarded the Framework.
The successful supplier will be expected to work collaboratively with the Client, contribute to social value outcomes, support carbon reduction objectives and demonstrate high standards of health and safety, compliance, and service delivery across all commissioned works.

How this framework works
From the published notice- Type
- Closed framework
- Call-offs
- call-offs are awarded directly to appointed suppliers, without further competition
- Places
- up to 1 suppliers
- Framework period
- 2 yrs · up to 5 yrs from 1 Nov 2026
- Supplier levy on call-offs (max %)
The framework will be established by Arc Partnership for use by Arc Partnership. As such no fees for access will be charged to the successful supplier.
Published description of the framework
As this is a single-supplier framework, pricing will be established at Stage 2 of the procurement process through the Framework Commercial Model. This will define the applicable pricing mechanisms, which may include schedules of rates, agreed overhead and profit percentages and compensation event discounts in line with NEC contract principals. This will form the basis for pricing all call-off contracts.
The Supplier is required to operate an open-book approach to all works under this Framework, providing full transparency of costings and supporting records to demonstrate compliance with the agreed pricing mechanisms. The Client shall have the right to review and audit such information to ensure value for money and alignment with efficiency objectives. Full details of these requirements are set out in the Framework Conditions.
Individual call-off contracts will be awarded via Requests for Quotation (RFQs). For each RFQ, the Supplier will submit a priced proposal in accordance with the Framework Commercial Model. As a single-supplier framework, awards will be made on the basis of the submitted quotation meeting the requirements of the RFQ and demonstrating value for money, assessed against criteria which may include price and, where appropriate, quality and delivery considerations.

- Price carries 30 of 100 points: a 10% discount moves about 3 points. The method statement decides this lot, not the discount.
- “AP25177 - Mechanical Engineering Framework” is a framework: the contest is a place on its panel, up to 1 suppliers, not a single contract, and call-offs are awarded directly: getting appointed is the whole game.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.

Mechanical installations (CPV 4535) in East Midlands, and who usually turns up
Arc Property Services Partnership Limited has too little published record in this market to describe on its own. Published market evidence for the same work stands beside whatever it has. This notice is a framework or DPS, so only frameworks and DPS are compared. Whole-market view: Mechanical installations (CPV 4535) →

Each colour shows awards below, close to or above the published estimate, one lot at a time.
On a framework or DPS, prices are agreed when work is called off.
Past prices are a guide, not a bid price.
Not comparable on a framework or DPS. The notice sets up a supplier panel and a ceiling value; what the work actually costs is agreed later, on each call-off or mini-competition, and those publish as contract notices of their own. The award-vs-estimate record of this market therefore sits on the call-offs; this page shows it on the contracts, not on the panel that frames them.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
