Some useful tips to read civil engineering drawings efficiently

This construction video tutorial sifts through the process for evaluating engineering drawing easily.

In this video, some crucial topics like grid lines in civil engineering, problems found in the drawing, are explained briefly.

A civil drawing contains a series of various types of site drawings. It is a type of technical drawing that provides information on utility, grading and drainage, site improvements, and landscaping plans as well as other site details. The objective of these drawings is to provide a clear conception of all things in a construction site to a civil engineer. In these drawings the site layout plan and floor plans are set up.

Civil drafters arrange the drawings, topographical and relief maps which are applied in leading construction or civil engineering projects like highways, bridges, pipelines, flood control projects, and water and sewage systems.

In the drawing, there are Grid Lines specified with dimensions n. The grid lines facilitate references to be created on the basis of the position/location of different constituents in the project. The Main Contractor will then employ a license surveyor to organize the grid lines on site.

In the video, a sample drawing is considered. There are 8 columns in this drawing with the dimension 29.5” x 19.5”. Here the header lines will demonstrate the center line of the column.
