Pick Everard has developed a bespoke Single Stage Design and Build (SSDB) procurement processes, specifically to capture and incorporate the benefits of collaborative Two Stage Design and Build (2SDB) procurement. This enables us substantially to reduce the risks typically perceived or experienced by the market as embedded within a typical approach to SSDB procurement. Those risks, typically, are:
Poorly coordinated or incomplete RIBA Stage 3 tender designs. This can result, at delivery stage, in the contractor bearing additional design and, typically, construction costs as well as programme delays, whilst areas of poor coordination and fit are resolved.
To overcome this, we issue, at tender stage, fully coordinated Revit 3D models, which clearly demonstrate coordination and fit of all principal components. Possession of the Revit models, plus design calculations, demonstrates that structural and external cladding zones, stair and services cores, plant rooms and vertical and horizontal services distribution routes have been tested for coordination and fit. This substantially reduces the detailed design risks to be borne by the contractor.
Poorly presented Employer’s Requirements (ER) and Contractor’s Proposals (CP). These lead, typically, to equally unclear and heavily qualified CP, often leading to lengthy delivery stage disputes.
To overcome this, we have established a standard structure for both ER and CP, which follows a 2SDB procurement route. The ER section is presented in a clear, standard form and the required presentation, form and content of the CP are mandatory. The CP must be returned in a specific, hierarchic format:
A ‘Statement of Compliance’ Letter stating that the CP are fully compliant with the ER, save where any departures have been specifically identified within the Derogations Register. The Derogations Register is the only document where a Derogation or alternative offer can be lodged and accepted.
Clarifications must be noted on the Clarification Register and accepted / rejected as compliant. The Clarifications Register is the only document where a clarification can be lodged and accepted.
Risk is allocated between Employer and Contractor as set out within the Conditions of Contract, save where both parties have accepted any alternatives, as set out within the Risk Register. All construction delivery risks (asbestos, ground conditions, etc.) are deemed to be at the contractor’s risk unless specified otherwise within the risk register.
The Derogations, Clarifications and Risk Register become Contract Documents
We have had considerable success with this approach to SSDB tender action in a current market where many contractors have decided to avoid SSDB procurement completely. Adopting this approach, we have successfully procured £100m of schools within the last 12 months converting competitive SSDB tenders into successfully exchanged contracts.
