  1. Introduction to FIDIC - Drawings -

  2. Definitions • FIDIC Red Book defines the Drawings as: • 1.1.1.6 – “Drawings” means the drawings of the Works, as included in the Contract, and any additional and modified drawings issued by (or on behalf of) the Employer in accordance with the Contract • Under FIDIC Conditions of Contract, Drawings are well down the order of precedence of the various documents constituting the Contract. • The Drawings are the lifeblood of the key data, describing: • A ‘Picture’ of the Works • The Scope of the Works • Inter-relationship of the various sections of work forming the whole • Dimensional requirements and fit

  3. Drawings • The Tenderers will rely at a great extent on the Drawings for their understanding of the Project and their strategy to price and programme the Works • A Drawing Manual is essential to govern consistent production and standards • Each Implementing Agency will have its own standard as will specialist Consultants • Care is needed to ensure a mutual standard between various organisations • Major schemes may require both unique design drawings and standard (typical) detail drawings • Presentation and detail accuracy • Made easier through Computer Aided Drafting (CAD)

  4. Key Factors for Drawings Production • Design information for the sole purpose of the intended use of the drawing, do not use the same drawing for different purposes • Maximise efficiency through a policy of minimum detailing without compromising quality and integrity • Drawings must be clear, accurate and concise and contain no ambiguities • The numbers of drawings must be kept to a logical minimum, and avoid duplication • Group common elements on detail sheets with extensive use of cross referencing

  5. Key Factors for Drawings Production • Drawings should have limited and efficient data, notes should only be for clarification and not repeat data • All units shown on drawings shall follow the “Système Internationale“ (SI) convention and all linear dimensions shall be in millimetres (mm). • A North Point to be correctly orientated • Alignment drawings. • Graphic scale bars must be provided on all scale drawings

  6. Classifications for Drawings • Sketches • Cover Drawings • General Arrangements • Plans and Profiles • Diagrams and Schematics • Directive Drawings • Detail Drawings • Assembly/ Component/ Parts Drawings • Schedules/ Tables • Typical Details • Standard Drawings • Reinforce Concrete Detail Drawings • Method Statement Drawings

  7. “Design Freeze” Phase • During project preparation, there are studied different alternative that are may generate other ones • At a certain moment the need of the project to advance to a next stage will require these studies to be stopped and carry on with a preferred one – “design freeze” • Revisions made after ‘design freeze’ may lead to expensive variations. • Variations will be used only when really necessary for the successful completion of the project

  8. Drawings - FIDIC Clauses • Clause 1.8 – Care and Supply of Documents: “The Specification and Drawings shall be in the custody and care of the Employer”. • Clause 1.9 – Delayed Drawings or Instructions: “The Contractor shall give notice to the Engineer whenever the Works are likely to be delayed or disrupted if any necessary drawing or instruction is not issued to the Contractor within a particular time, which shall be reasonable. The notice shall include details of the necessary drawings or instruction, details of why and by when it should be issued, and details of the nature and amount of the delay or disruption likely to be suffered if it is late. If the Contractor suffers delay and/or incurs Cost as a failure of the Engineer to issued the notified drawing or within a time which is reasonable and is specified in the notice with supporting details, the Contractor shall give a further notice to the Engineer and shall be entitled subject Sub – Clause 20.1 [Contractor’s Claims] to: • an extension of time for any such delay, if completion is or will be delayed, under Sub – Clause 8.4 [Extension of Time for Completion], and • payment of any such Cost plus reasonable profit, which shall be included in the Contract Price. After receiving this further notice, the Engineer shall proceed in accordance with Sub – Clause 3.5 [Determinations] to agree or determine these matters. However, if and to the extent that the Engineer’s failure was caused by any error or delay by the Contractor, including an error in, or delay in the submission of, any of the Contractor’s Documents, the Contractor shall not be entitled to such extension of time, Cost or profit.
