proven capability, nationwide

B2G PSR is a single lot framework covering all parts of the UK, within which each Supplier can designate (and update) their active regions and preferred project value ceilings and floors. Buyers may restrict invitations and Suppliers decline invitations based on those preferences. However, Buyers retain the right to invite and contract with any Supplier to deliver services anywhere in the 'lot' (ie. the UK) and Suppliers retain the right to deliver services for any Buyer anywhere in the 'lot' (ie. the UK).  

This innovative approach delivers optimum procurement efficiency and minimum carbon footprint to the benefit of all parties.

community benefit comes as standard

As a requirement for being appointed to the framework every bidder confirmed their willingness to deliver all the measures set out in the Considerate Constructors Scheme's Social Value Checklist which, depending on the size and nature of the Project and the needs of the local community, might include:

Local employment

Full & part time; apprenticeships; work experience

Supply chain

Local sub-contractors, suppliers, social enterprises, NGOs & charities

Supplies & equipment

Locally manufactured; reused or recycled; or sustainably sourced 

Community engagement

Educational (eg. engaging with local schools & colleges etc); social (eg. engaging with local clubs & charities etc); or environmental (eg. litter patrol & work parties etc)

flexible and efficient

Buyers can direct award any supplier confident they will deliver to a quality that meets or exceeds all regulations and standards, at a competitive price, and in full support of the Public Services (Social Value) Act 2012, thus generating both commercial AND social value - embodying the principles of MEAT.

Registration

The Buyer registers the project with B2G - document can be downloaded from this website 

Procedure

The Buyer has the option to hold a mini-competition or to direct award a contract to any Supplier, and may apply their own criteria or weightings, subject to ensuring that any action taken is transparent, non-discriminatory and fair. 

Assignment

In each case, if a significant part of the Project is to be delivered by a specialist sub-contractor registered on the B2G DPS, then the Project may be assigned to that specialist contractor (the Assignee) and the Buyer then contracts directly with the Assignee to deliver those works, supplies and or services, compliant with the specification, standards and regulations set out in the framework documents. The decision to assign and selection of the Assignee are both controlled by the Buyer, and assignment may be direct or via mini-competition.

Contract

The Buyer can use their preferred form of contract, which may be one of the JCT/SBCC, NEC or PPC/FAC/TAC suites of contracts or the Buyer’s modified version, or any other standard form of contract or Pre-Contract Service Agreements (PCSA)  used by the construction industry.

Delivery

The project is delivered according to the agreed KPIs and terms and - for the avoidance of doubt, whether self-performed or assigned - compliant with the specification, standards and regulations set out in the framework documents. B2G monitors the project.

Price increases

Price increases (including for materials) can be applied in line with either BCIS (Building Cost Information Service) or RPI (Retail Price Index) or CPI (Consumer Price Index) using ONS (Office of National Statistics) data and applying the Framework’s month of launch as the base index.

Notices

A Prior Information Notice (PIN) was published on 12 March 2024 the Contract Notice (CN) was published on 22 April 2024; and the Contract Award Notice (CAN) was released for publication on 18 July 2024.

Participation

52 requests for the ITT documentation were received. Multiple submission date extensions were requested and granted, extending the deadline from 31 May 2024 to 14 June 2024, to take account of the fact that it was half term, so bid teams were short staffed. All active participants were notified, and the framework webpage was also updated with the new submission date. 15 bids were received on or before 11pm on 14 June 2024. No late submissions were received.

Evaluation

Our objective was to assure competent suppliers who offer competitive rates. We set the bar accordingly high. Each section of the bid document was scored separately, and weighted as follows:

• Standard Questions
  This section is pass/fail. Standard Questions were based on PAS91 & ESPD format, covering company and financial standing, the latter evaluation based on financial accounts and insurance certificates submitted with each bid, and full independent financial reports from Veriphy, including current credit status, with emphasis placed on proven sustained profitability and a positive current ratio. Nevertheless, and for the avoidance of doubt, since our check only relates to each Bidder's financial standing at the time of the evaluation, buying authorities are responsible for carrying out their own due diligence for each call off project. 

• Social Value
  This section is pass/fail. Social Value support by all bidders was confirmed across four categories of measures (in accordance with the Social Value Checklist developed by the Considerate Constructors Scheme) covering local employment, supply chain, supplies and equipment, and community engagement.

• Quality
  This section was weighted 50%. The objective was to assure competency and proven experience, with a focus on third party certification and project references. Because each bidder was presenting 6 projects undertaken for different buyers, it was unfair to score bids against one another, as one cannot benchmark how 6 referees might each differentiate between 'good' and 'excellent and score it as a mark out of 10. Nor did we feel that adds value to the process. Instead we focused on asking each referee to confirm their project was delivered to the client's satisfaction, and the client would be happy to contract that bidder again. We felt it was far more important that future clients would be assured that every Supplier we appoint has a track record of delivering quality. Consequently, top rank is shared by all Suppliers whose referees were willing to attest to this. 

• Price
  This section was weighted 50%. We adhere to the principles of the UK.gov 'Should Cost Model', with a focus on achieving competitive sustainable pricing and avoiding a race to the bottom. Bidders submit OHP% and standard service item costs. We evaluate each line item separately, and rather than ranking an arbitrary basket of rates, or ranking the price for hypothetical projects loaded with contingency, we seek to ensure bidders are submitting consistently comparable 'market rates' to their peers. Bids may be excluded if their rates are consistently and significantly higher (and thus deemed 'uncompetitive') or consistently and significantly lower (and thus deemed 'unfeasible') than any other bid. Top rank is shared by all Suppliers not excluded by the above criteria.

Award

Pursuant to Clause 87 of the Public Contracts Regulations 2015 preliminary award notices were issued to 14 bidders on 8 July 2024, each of whom share top rank for quality, price and VFM, and can each therefore be direct awarded to any project, by any contracting authority, anywhere in the UK. A period of standstill ran through to midnight at the end of 18 July 2024. No challenges were received, and consequently Award Confirmations were sent to each bidder.

On 25 February 2025, a bid was received from Maguire Bros Limited. As per the terms of the Framework Agreement which allow for additional suppliers to be appointed, subject to submitting a bid that is evaluated in accordance with the same criteria, Maguire Bros Limited was awarded to the Framework on 11 March 2025 and an Award Confirmation sent on the same day. 

On 24th April 2025 documentation was received confirming the acquisition of the Breyer Roofing division by Cardo (South) Limited, and pursuant to the framework terms, B2G consented to the assignment of all rights and responsibilities to Cardo, who were duly registered as the appointed company.
