Pre-construction services agreement PCSA
- Contribute to the design process itself.
- Advise on buildability, sequencing, and construction risk.
- Advise on the packaging of the works (and the risks of interfaces between packages).
- Advise on the selection of specialist contractors.
- Help develop the cost plan and construction programme.
- Help develop the method of construction.
- Obtain prices for work packages from sub-contractors or suppliers on a open book basis.
- Prepare a site layout plan for the construction stage showing temporary facilities.
- Draft the preliminaries for specialist and trade contractor bid documents.
- Assist with any planning application on matters concerning the build phase, such as; waste disposal proposals, construction traffic movements, tree preservation protection, etc.
The PCSA will define the services that are required of the contractor during the pre-construction phase and is generally similar to a consultancy agreement. It should make clear whether the contractor is undertaking design work, whether they will have any design liability, and what will happen to this liability if they are not appointed for the second stage. It should also set out the method of payment, and any provisions for deferred payment.
The contractor appointed under the PCSA will not necessarily be appointed for the second-stage construction contract. However, the client inevitably loses leverage in the second-stage of the tender process, as the contractor becomes embedded in the team and potential competitors lose interest once they find out that another contractor has been awarded the first-stage tender.
However, a longer period of familiarity with the project creates better relationships as well as a reduction in learning curves and programme performance, and so, whilst tender prices for two-stage contracts may initially be higher than single-stage tenders, which are subject to full competition, the final account tends to include fewer variations and fewer claims. Competition can be introduced into the second stage by an open-book approach to the tendering of sub-contracts.
It is important that the client ensures they have some means of securing an alternative bid if second-stage negotiations fail, albeit this is likely to result in delays and difficulties regarding design liability.
PCSAs are often used on design and build projects to obtain early input from the contractor. They can also be used to obtain pre-construction services by specialists, appointed either by the contractor, or by the client (for example on a construction management contract) or on Private Finance Initiative (PFI) or Public Private Partnership (PPP) projects to obtain contractor input to a consortium bidding for a project.
