NEC4: Engineering and Construction Subcontract
The NEC4: Engineering and Construction Subcontract (ECS) is for appointing works subcontractors where the main works contractor has been engaged under an NEC4 Engineering and Construction Contract (ECC).
Containing the same definitions and procedures as an ECC contract, the ECS provides back-to-back protection for the main contractor and consistency of approach throughout the supply chain. It can include any level of design.
The document includes five main payment Options: A (priced subcontract with activity schedule), B (priced subcontract with bill of quantities), C (target subcontract with activity schedule), D (target subcontract with bill of quantities) and E (cost reimbursable subcontract). A different Option from the main contract can be used in each subcontract.
In addition to the main Options, the document contains everything you need to prepare, tender and manage an NEC4 ECS subcontract, including all secondary options and forms for the relevant cost schedules and contract data.
The NEC4 ECS is part of the NEC4 suite of collaborative, flexible and clearly written contracts for built environment procurement. The suite has a global track record for delivering all kinds and sizes of building and infrastructure projects on time, on budget and to the highest environmental and quality standards.
As with all NEC4 contracts, the parties to an ECS are required to act in a ‘spirit of mutual trust and co-operation’ and give early warnings of anything that could affect time, cost or quality so it can be mitigated without delay. Change is dealt with by a fast and fair compensation event process which, together with a continually updated and agreed programme, ensures there are no surprises at completion.
