About the Framework

Developed in partnership with Contracting Authority Watford Community Housing, the framework has been created to support with the design and delivery of rooftop developments.

Using under-utilised rooftops to create much-needed homes, classroom space or additional medical facilities, rather than constructing new buildings from scratch, has many benefits.

As well as providing a practical solution where space is limited, it is cheaper and more sustainable to enhance an existing building than to construct a new one.

Accessing the Framework

Authorised Users must sign an Access Agreement with the Contracting Authority in order to use the framework

You can choose between Mini-Competition and Direct Award (see section below for more information).

On completion of the framework procurement process (either Direct Award or Mini-Competition) the Authorised User will enter into a call-off contract with the selected supplier, using an industry standard form of construction contract. Authorised Users can choose to appoint consultants using the Framework Letter of Appointment or Deed of Appointment.

Contracts can be awarded via Direct Award or Mini-Competition to suit operational requirements and project circumstances, and a member of the Pretium team will advise and support you through the call-off procurement process.

Direct Award

Direct Award offers the mechanism to issue work directly to the supplier without any further tender. 

Authorised Users may award directly to a framework supplier in any of the following circumstances: 

  • Where the framework service provider is the number 1 ranked framework service provider on the framework lot in question (as shown in the fourth column of the table in Schedule 1). If such framework service provider either declines the award of the call-off contract or the Trust or the Authorised User, acting reasonably and having regard to the capability criteria, does not consider that it is capable of carrying out the call-off contract, the Trust or the Authorised User may award the call-off contract by Direct Selection to the framework service provider who is the number 2 ranked framework service provider on the framework lot in question, and so on and so forth.    
  • Where the framework service provider has already carried out works and/or services at risk for the Trust or the Authorised User in relation to the site to which the call-off contract    
  • Where the call-off contract has substantial similarities to a previous project in which the framework service provider was involved (whether such project was the subject of a call off contract awarded under this Framework Agreement or not).   
  • Where for reasons of urgency it is not reasonably practicable to award the call-off contract by way of a Mini-Competition.   
  • Where the Trust or the Authorised User has determined through application of the capability criteria that only that framework service provider is capable of carrying out the call-off contract.

All suppliers within the framework are invited to participate in a mini tender specific to the works being called off. 

The Authorised Users will identify the framework suppliers appointed to the framework lot, who are capable of carrying out the particular call-off contract and invite those framework suppliers to participate in the mini-competition. 

Authorised Users may use capability criteria to determine which framework suppliers are capable of carrying out the call-off contract and are therefore invited to participate in the mini-competition. 

The Pretium team manage this process on the Authorised User’s behalf or can offer support, as and when required, including document templates. The process can be managed through Procurement portal, EU Supply/Mercell or directly by the authorised user through their choice of portal.  

Whichever option you choose, you may wish to understand which of our trusted suppliers have the capacity to deliver your project, through an Expression of Interest (EOI). Our team will gather your project information into an EOI template which will be issued to all suppliers. Their responses are then collated and presented to you in a summary document to help inform decision making moving forward.
