Guidelines For Drawing Project Precedence Network

The networks drawn using standard conventions are easily readable and acceptable. These rules for drawing networks depend upon the network technique employed.

Network Purpose

A project needs different types of networks like master network, summary network and contract control network, at various levels of control. The first step in drawing a network is to decide upon the type of network required and then draw separate networks incorporating relevant information for each level of control.

Initially, the draft of the network should be prepared in pencil, discussion at various levels. As far as possible, the level of activities within a network should be kept consistent.

Network Drawing Sheet Size

Each type of network should be drawn on convenient size sheet not exceeding A0 size (1189 mm X 841 mm). An A0 size drawing sheet is sufficient for as many as 200 activities. Networks should be split into various sub-networks linked by the interfacing activities or events (shown in boxes or circles) and should be drawn on smaller size (A3 or A4) paper.

Project Network Layout Stratification

Prior to the commencement of integration, the paper on which the project network diagram is to be drawn should be divided into various strata. Stratification means division of the network diagram in such a way that activities pertaining to the same department, contract, location or method of construction, can be grouped by drawing horizontal and/or vertical lines. Generally, the strata can be visualized from a prior knowledge of the scope of work in a project. These can also be easily deduced from the work-breakdown structure.
