Introduction to Specifications Writing

Introduction to Specifications Writing

• Construction specifications are detailed documents defining materials, standards, and workmanship for projects.
• MasterFormat, created by CSI, organizes specifications into 16 divisions based on major construction trades.
• In 1963, MasterFormat was initially created.
• In 1978, it was expanded to include section numbers and titles.
• In 2004, it was further developed to 50 divisions to cover a wider range of construction elements, including computer networks, telecommunications, facilities management.
• Updated regularly to adapt to industry changes like BIM (Building Information Modeling) for improved construction efficiency.

Types of Specifications

• Prescriptive: Details exact materials, products, and installation methods.
  • Example: Using 3000 PSI concrete for footings.
• Performance: Focuses on desired performance outcomes.
  • Example: Maintaining an indoor temperature of 22°C.
• Proprietary: Specifies particular products or manufacturers.
  • Example: Using Davies Paint for interior walls.
• Reference Standard: Refers to established standards or codes (e.g., ASTM, ISO).
  • Example: Using ASTM A36 standards for structural steel.

Specification Writing Styles

• MasterFormat: Widely used system for organizing specifications into divisions and sections.
  • Example: Roofing systems fall under Division 07 (Thermal and Moisture Protection).
• Performance-Based: Focuses on outcomes and performance criteria.
  • Example: Roofing system withstanding wind speeds of 150 km/h.
• Uniformat: Organizes information based on systems or assemblies.
  • Example: House breakdown into substructure, foundation shell, exterior walls, etc.
• Descriptive: Detailed descriptions of materials and workmanship without brand names.
  • Example: Using 2-inch mineral wool insulation with a minimum R-value of 4.0 per inch.

CSI MasterFormat 16 Divisions

• Originally consisted of 16 divisions (e.g., electrical, masonry, finishes).
• Example: Division 09 includes drywall, painting, and ceiling tiles.

CSI MasterFormat 50 Divisions

• Broken into 50 divisions, each relating to a specific aspect of construction (e.g., finishes, metal, HVAC, electrical, concrete).
• Divisions 15-20 are reserved for future development.

Application of Specifications Writing

• Construction Documentation: Detailed instructions on materials, finishes, and standards.
• Bidding and Procurement: Guiding contractors and suppliers in preparing bids, ensuring fair competition.
• Contract Administration: Legally binding contracts, resolving disputes.
• Quality Control: Setting standards for materials and workmanship to ensure project quality.
• Sustainability: Details eco-friendly materials and systems, like LEED certifications.
• Government and Private Projects: Compliance with relevant standards (e.g., DPWH, National Building Code).
• Legal and Safety Compliance: Aligning projects with safety regulations.
• Dispute Resolution: Helps identify material requirements, liabilities, and responsibilities.

MasterFormat Structure

• Division (Level 1): Highest level, encompassing 50 divisions.
• Section (Level 2): Within each division, covering specific work aspects. Example: "Division 05 Metal" with sections for structural metal framing, metal joists, etc.
• Subsection (Level 3): Further segments of sections, providing detailed work specifics. Example: "Structural Steel Framing" within "Structural Metal Framing."

Example Specification Number Format

• Example format uses three parts: Division, Section, and Subsection.
  • Example: 06 41 93 (Division 06, Section 41, Subsection 93, for Cabinet and Drawer Hardware).

CSI MasterFormat 3 Part Format

• Part 1 (General): Administrative and procedural requirements (e.g., submittals, quality assurance, warranties).
• Part 2 (Products): Detailed descriptions of materials, products, and mixes.
• Part 3 (Execution): Methods for site preparation, installation, erection, and quality control.

MasterFormat Uses in Construction

• Estimating: Accurate project cost predictions.
• Bidding Management: Ensuring all components are included in bids and easier comparison.
• Procurement: Identifying needed materials and communicating requirements to suppliers.
• Budget Management: Organizing cost codes, matching estimates to actual expenses, and simplifying data transfer.
• Construction Management: Organizing work schedules, coordinating tasks, optimizing resources for efficient processes.
• Facilities Management: Structuring maintenance manuals to improve access to information for upkeep and replacement of components.

This quiz covers the fundamentals of construction specifications writing, including the structure and history of MasterFormat. You'll learn about different types of specifications, including prescriptive, performance, and proprietary specifications, and how they define project requirements. Test your knowledge on key concepts and terminology essential for construction management.
