Engineering systems drawings

The development of plans for utility networks is carried out on the basis of working drawings of the general plan, roads and railways or topographic plans.

The following designations are applied to the plans of engineering systems:

• already constructed and designed buildings and utilities that affect the construction and installation of networks;
• coordinates of engineering systems and their binding to the coordinates of structures;
• diameters of the designed pipeline systems;
• wells, chambers, storm water inlets, crossings under road and railway tracks.

Trunk system plans may contain picket numbers (PK) with reference to network sections. At the customer's request, it is possible instead of plans by engineer. systems execution of individual fragments. In this case, the names of the plans are indicated without abbreviations.

Sketch drawings of non-standard products

The execution of sketch drawings developed for elements of engineering structures that are not mass-produced is regulated by GOCT 21.114. Separate sketch drawings are created for each element with non-standard parameters. It is allowed to create group drawings for components of a structure that have common design features. Sketch drawings are assigned independent designations, which include the name of the set of RF (working drawings) in accordance with GOST 21.101, code H and the serial number of the sketch drawing.
