How to read a spec section: Part 1, Part 2 and Part 3

Most spec sections have three parts. Part 1 General covers the rules. Part 2 Products covers what you supply. Part 3 Execution covers how you install it.

Part 1: General

Part 1 sets the administrative rules for the section. It does not list products, but it does carry cost.

  • Summary. What the section includes and which sections relate to it.
  • Submittals. Product data, shop drawings, samples and certificates you must send.
  • Quality assurance. Installer experience, manufacturer qualifications and mockups.
  • Delivery, storage and handling.
  • Warranty. The length and the terms.

Part 2: Products

Part 2 names what you supply. Read the manufacturers paragraph first. It tells you which makers are acceptable and whether substitutions are allowed. Then read each product paragraph. Write down the model, size, material, finish and accessories for each item.

Look for the phrase basis of design. It means one product set the standard. Other products must match it. Look also for options that the architect selected. A product line can come in three finishes, and the spec picks one.

Part 3: Execution

Part 3 covers the work on site. It lists how to examine the area, prepare it, install the product and clean up. It can also require field testing, adjustment and owner training. These items take labor. An estimate that prices only Part 2 will come in low.

A reading order that works

  1. Read the Part 1 summary and the related sections.
  2. Read all of Part 2 and list each item with its model or type.
  3. Read Part 3 and list each task that takes labor or equipment.
  4. Go back to Part 1 for submittals, mockups, warranty and extra materials.
  5. Mark each line that is unclear and ask about it before the question deadline.

Words to watch

Furnish means supply the item. Install means put it in place. Provide usually means both. Check the definitions in Division 01, because the contract can define these words itself.
