What you'll be tested on

The skills behind Specifications and MasterFormat questions.

Examitect drills each of these areas. The list below maps to the question categories you'll see inside.

  • Understand specification writing principles (clarity, coordination, accuracy)
  • Apply MasterFormat organization (Divisions 00 to 49)
  • Use the National Master Specification (NMS) as a starting point
  • Write performance, prescriptive, and proprietary specifications appropriately
  • Coordinate specifications with drawings and consultant documents
  • Apply SectionFormat and PageFormat conventions

Why this topic matters. Specification questions test whether you can write requirements a contractor can price and execute. Examiners reward candidates who pick the right specification method (performance, prescriptive, proprietary) for each situation.

Study Notes on Specifications and MasterFormat

Specifications basics

Specifications are the written half of the construction documents. They describe quality, materials, products, installation, and acceptance. A good spec is clear (unambiguous), coordinated (matches the drawings), and accurate (technically correct). The CSI three-part section format (General, Products, Execution) is the Canadian standard.

What specifications cover

MasterFormat organizes specifications into 50 divisions: 00 (procurement, contracting), 01 (general requirements), 02 to 19 (existing conditions, concrete, masonry, metals, wood and plastics, thermal and moisture protection, openings, finishes, specialties), 20 to 29 (services), 30 to 49 (site work, other). The NMS provides Canadian-specific section text.

Numbers worth memorizing

MasterFormat has 50 divisions. Three-part SectionFormat: Part 1 General (administrative and quality requirements), Part 2 Products (materials and equipment), Part 3 Execution (installation, acceptance). PageFormat: three levels of paragraphs (article, paragraph, sub-paragraph) numbered .01, A, 1, a, 1).

Common ExAC traps

Watch for distractors that use proprietary specifications (e.g., manufacturer X model Y) where performance or prescriptive would be more appropriate. Public sector projects typically prohibit proprietary specs. Make sure or-equal language is added where required. Don't specify means or methods unless safety is involved.

FAQ

Specifications and MasterFormat questions.

National Master Specification, maintained by the federal government and updated regularly. It provides Canadian-specific text for most MasterFormat sections. Architects edit NMS text for project-specific use.

Prescriptive describes materials and methods. Performance describes the required outcome. Proprietary names a specific product. Performance gives the contractor flexibility; prescriptive gives the architect control.

Division 01 (General Requirements) covers procedures that apply to all sections: submittals, meetings, payment procedures, quality control, project closeout. Don't put generic requirements in technical sections.

8 to 12 hours. Reading the NMS table of contents is the fastest way to internalize MasterFormat.
