Drawings and Plans play essential role in construction procedures. Without Drawings and Plans the construction works have neither an objective nor a stated quality of the desired outcome. Design procedures specify measurable standards of the construction like the energy efficiency, structural capacity, fire resistance rating, sound insulation and much more. Without Design procedures and the site inspection that follows, the achieved quality of the above standards is unspecified. Design procedures result in a series of Drawings that are required for the statutory approval of a building, such as:
• Architectural Drawings: These drawings define the size, type and aesthetics of the development.
• Structural Drawings: They ensure that the building conforms to anti seismic and structural regulations. It aims at finding out safe and economical specifications for the structure.
• Electromechanical Drawings: They specify the electromechanical installations of a building including Renewable Energy Systems (RES).
• Energy Efficiency Certificate: It is the “energy” document of the building, so to speak. It specifies, among other things, the type and thickness of the thermal insulation of the building as well as the performance and consumption of the electromechanical installations.
Depending on the scale and type of the development, more Drawings and Documents could be needed for Statutory Approval such as Environmental Impact Assessment, Traffic Impact Study and Geotechnical Investigation. Nevertheless, for proper construction and site inspection, the following Drawings and Documentation are useful:
Detail Drawings: These Drawings determine the exact construction solution for each structural element. Particular importance is given in specific problems like moisture and thermal insulation of the buildings as their incorrect application, especially in the junction of the structural elements can cause serious problems in the future. Most of the times Detail Drawings are accompanied by Technical Specifications.
Technical Specifications: A written document where the quality and type of materials that are to be used in construction works, are defined. This document specifies in detail the quality and type of materials that are to be used. It complements the Detail Drawings as it mentions crucial information that is not present on the Drawings. Detail Drawings and Technical Specifications are part of the Tender Documents, alongside the Construction Contract.
Quantity surveying: It aims at preparing the Bill of Quantities, where construction works are listed with a detailed description, their corresponding quantities and of course the price. The Bill of Quantities is another important document that is often used alongside other Tender Documents.
Other Drawings that could be requested by the owner for purposes of quality and comfort are Bioclimatic Design and Landscaping.
