Clause 4 sets out various obligations which fall on the Contractor under the Contract and which cannot easily be classified elsewhere. The obligations under Clause 4 are of a wide range covering 24 different topics. Sub-Clause 4.1 sets out the Contractor’s general obligation to carry out his duties in accordance with the contract. Clause 4 of the FIDIC Red Book 1999 amalgamates various Contractor obligations under one provision. However this Clause 4 is not exclusive as there are also other Contractor obligations scattered throughout the Contract. Other significant general obligations which could equally have been included in Clause 4 (and which should be read in conjunction with this Clause 4) are as follows: • Sub-Clause 1.3 [Communications] • Sub-Clause 1.7 [Assignment] • Sub-Clause 1.8 [Care and Supply of Documents] • Sub-Clause 1.9 [Delayed Drawings or Instructions] • Sub-Clause 1.10 [Employer’s Use of Contractor’s Documents] • Sub-Clause 1.12 [Confidential Details] • Sub-Clause 1.13 [Compliance with Laws] • Clause 6 [Staff and Labour] • Clause 7 [Plant, Materials and Workmanship] • Sub-Clause 8.2 [Time for Completion] • Sub-Clause 8.3 [Programme]
