Engineering Contract Conditions.
The standard conditions emerged after the Second World War in the United Kingdom. Prior to this, there are divergent forms of contract used by various public and private bodies. The Engineers Institute General Conditions date from 1980. They largely restate the UK ICE conditions of contract. These may been replaced in the UK by the NEC’s new engineering contract forms which later emerged.
The following are the principal headings in the EI General Conditions
- Definition and interpretation
- engineers representative
- assigning and subletting
- contract documents,
- general obligations,
- workmanship materials,
- time and delay,
- liquidated damages,
- completion certification,
- maintenance and defects
- alterations and additions,
- property in plant and materials,
- provisional and prime costs sums
- nominated subcontracts,
- certificate of payments,
- remedies and powers
- work laws,
- settlement of disputes,
- special conditions.
The tender total is the total of the priced bill of quantities as of the date of acceptance. The contract price is the sum to be ascertained and paid under the contract in respect of the works. The default position is that the works are to be valued on a measurement basis.

The engineer may direct the contractor to give reasonable facilities for other contractors employed by the employer and persons authorised, undertaking contract work or otherwise persons at or near the site. The contractor must leave the site and permanent works in a clean and workmanlike manner on completion.
The contracts require compliance with industry wage standards, at a minimum. The engineer may require plant and labour returns from the contractor or any subcontractor
The contract provides for the quality of materials and workmanship to be provided and the contractor’s obligations in relation to samples and testing. The cost of tests are to be borne by the contractor if the test fails but to be borne by the employer otherwise.

The engineer may order variations in the works. They must be necessary for the completion of the works. This will have implications in terms of time and cost.

- further drawings and instructions,
- suspension of the works,
- issues with possession of the site
- issues with program revision,
- certain delays.

FIDIC civil conditions of contract have gone through o a number of editions. Part one is a general condition. Part two is the conditions specific to the contract. The contracts terms are broadly similar to the ICE engineering contracts.
The ICE contract and the FIDIC conditions of contract are measurement contracts with a bill of quantities included. In the case of a lump sum, target sum or cost-reimbursement contracts, the forms are modified in the circumstances. Modifications are reflected in the special condition.
The FIDIC form of agreement incorporates a letter of acceptance, the tender, conditions of contract, specification the drawing and the bill of quantities.
