Study Notes
Specifications
- Part of the contract documents that describes the technical nature of materials, standards, and quality of execution of the work to be placed under contract.
- Types of specifications:
- Performance specification: stipulates how a particular component or system must perform without giving the means to achieve the results.
- Descriptive specification: stipulates the exact quantities and qualities of materials to be furnished and how they are to be assembled in a construction.
- Reference specification: refers to a standard specification to indicate the properties desired in a material or component and the methods of testing required to substantiate performance.
- Proprietary specification: stipulates the use of specific products, systems, or processes without provision for substitution.
Uniform System (MasterFormat)
- Developed by the Construction Specifications Institute (CSI) for coordinating specifications, filing of technical data and product literature, and construction cost accounting.
- Organized into 16 divisions based on an interrelationship of material, trade, or function:
- 1: General Requirements
- 2: Site Work
- 3: Concrete
- 4: Masonry
- 5: Metals
- 6: Wood and Plastics
- 7: Thermal and Moisture Protection
- 8: Doors and Windows
- 9: Finishes
- 10: Specialties
- 11: Equipment
- 12: Furnishings
- 13: Special Construction
- 14: Conveying Systems
- 15: Mechanical
- 16: Electrical
Three-Part Section Format
- Part 1: General
- Scope, description of systems, requirements of regulatory agencies, qualifications, submittals, mock-up production handling, environmental conditions, protection, operating instructions, extra stock, alternates, measurement and payment.
- Part 2: Products
- Details of the quality of items required for the project, including materials, mixes, equipment, fabrication, and source quality control.
- Part 3: Execution
- Describes the quality of items required for the project, including conditions of surfaces, preparation, installation, field of quality control, adjusting, patching, cleaning, and schedules.
Estimation and Calculation
- Formula for calculating volume: V = length x width x height
- Examples of calculation problems:
- Estimating the quantity of cement, sand, and gravel needed for a footing.
- Finding the volume of excavation and backfill for a column footing.
Architectural Material and Finishes
- Masonry works:
- CHB (thickness) - 4", 6", 8"
- CHB (dimension) - 20cm x 40cm
- 12.5 pieces of CHB per 1 square meter
- Floor and ceiling finishes:
- Flooring: commercial sizes of tiles (e.g. 12 x 12 inches, 16 x 16 inches, 18 x 18 inches, 24 x 24 inches)
- Ceiling: ceiling board sizes (e.g. 2400-3000 mm in length, 900-1200 mm in width)
