Types of design and construction documents for heavy civil projects such as engineering design documents, bid documents, construction documents are discussed.
Generally, engineering design documents are divided into two major types including documents for not construction and documents for construction .
It involves all designs for instance conceptual design which is produced prior to the final design of the undertaking. often, documents for not building are considered as studies.
Design reports, design drawings, data reports, and engineering cost estimates are all products of the study phase of the framework. These design documents are used to assess technical and cost feasibility of different alternatives and options to obtain project purpose and objectives.
Finally, the detailing offered in these documents is less than those offered in the final design. on the other hand, it should offer sufficient detailing to illustrate concept and constructability of the framework in addition to offer a reliable construction cost evaluation.
Documents for construction are produced at the final design stage. Examples of these documents include construction drawings and technical specifications, design reports, engineer’s cost estimates, and bid schedule.
Number of these documents is produced for the owner whereas others are used by contractor, construction manager, and inspector for bidding and Construction.
Bid documents are prepared so as to offer necessary information to bidders during bidding period. It contains administrative, contractual, and technical requirements. Added to that, bid documents clarify tasks and responsibility of the owner, contractor, and the engineer. Table 1 offers various types of bid document along with their descriptions.
Table-1: Types of bid documents along with their descriptions
These documents are utilized for building the project after the bid is awarded. Construction documents of heavy civil projects are usually composed of agreement, general conditions, supplemental conditions, payment schedule, construction drawings, and technical specifications.
All construction documents are assumed to be a legal document that is why their contents shall be rigorously conformed so as to prevent disputes, ambiguity, and conflicts.
in addition, construction drawings, technical specifications, and pricing schedule are prepared by the engineer whereas other documents are furnished by the owner.
