Every construction project comprises multiple services. These range from structures to networks of ducts and pipes. And a successful project integrates them without overlapping or clashes. Spool drawings are a guide to these piping systems to ensure clash-free installation. These are used for plumbing, HVAC, and MEP fabrications.

Let’s understand these drawings and how they benefit the typical AEC workflow.

Decoding Spool Drawings and Their Purpose/ What are Spool Drawings?

Spool drawings exhibit every minute detail of prefabricated components used for a piping system. It displays information ranging from material specifications to dimensions for a particular segment of a piping system.

What is the Purpose of Spool Drawing?

1. Convey Sizes and Dimensions

These comprise accurate length, diameter, thickness, sizes, and types of fittings and valves.

1. Showcase the Routing and Layout of Pipes

It gives a clear layout, mentioning the location of fittings, valves, and other components.

1. Specify the Materials

These drawings give clear information on the type and grade of material used.

1. Illustrate Welding and Joining Details

Information regarding the joinery and welding of a pipe spool is conveyed through these drawings.

1. Mark the Types of Hangers and Supports

These illustrate the location and type of hangers and supports used in the piping system.

Critical Role of Spool Drawings in AEC Projects

These help seamlessly translate the details from BIM to physical construction. Here are the significant purposes catered to by these drawings:
