Construction specifications - vital for suppliers, purchasers, and users of materials, products, or services in engineering, manufacturing, and business

A specification (often abbreviated as spec) can be termed as a type of a technical standard to be referenced by a contract or procurement document. It contains the necessary details concerning the specific requirements to be persuaded by a material, product, or service.

The specifications are considered very important for suppliers, purchasers, and users of materials, products, or services in engineering, manufacturing, and business as these specifications cover up a extensive collection of general issues like definitions, bidding requirements, legal responsibilities, claims & payments; with details on specific items with respect to all construction project.
CSI (Construction Specifications Institute) is a renowned association that provides the standardization of construction language related with building specifications. CSI offers prearranged instructions for composing specification in their Project Resource Manual.
CSI published MasterFormat, an indexing system for categorizing construction data as well as construction specifications. It consists of 50 Divisions, to be applied for integrating facility life cycle and maintenance information into the building knowledge base.
Almost the entire CSI approved sections contain performance and safety obligations produced by agencies like the American Society for Testing and Materials (ASTM), Occupational Safety and Health Administration (OSHA), and several other federal and professional organizations.

CSI also publish GreenFormat, an online database that includes sustainable product attributes. Manufacturers associated with the construction industry will be able to register product information based on 5 categories in a widespread online questionnaire. All kinds of product information referenced by MasterFormat divisions and titles will be available to designers, specifiers, and building constructors.

Given below the detailed lists of construction specifications :-

General Requirements - Division 01
This specification will include particular administrative and procedural requisites that belong to all of the Technical Specification sections. The General Requirements consist of specifics relevant directly to a particular project and written independently for each project. These will develop the expansive administrative and procedural conditions inscripted in the General and Supplementary Conditions documents. These will be applicable to the work of ALL Technical Specification sections. This document also sum ups the scope of work, exercise of the site, owner occupancy of building throughout construction, Phased construction activities, numerous prime contract requisites and eliminations and additions to be connected with the Plans. The General Requirements narrate the Contractor's administrative, procedural and other activities which should be submitted by the Contractor. In General Requirements section the following categories will be available.

01010 Summary
01020 Allowances
01030 Alternates
01040 Coordination
01060 Regulatory Requirements
01080 Identification Systems
01090 References

01025 Measurement and Payment
01035 Modification Procedures
01050 Field Engineering
01100 Special Project Procedures
01200 Project Meetings
01300 Submittals such as Construction Schedule, Logs
01400 Quality Control
01600 Material and Equipment
01650 Facility Startup/Commissioning
01700 Contract Closeout
01800 Maintenance

Temporary Activities
01500 Temporary Facilities

The Contractor’s Responsibility is to comprise these items in Overhead.
Technical Specifications
Divisions 02 - 16 is known as the Technical Specifications. These construction specifications consist of the written description of the specific requirements regarding with a specific product or system. The specification provisions characterize and set up the quality level processes, standards of work and material standards. Each subsection will describe the scope, technical requirements, performance requirements, material suppliers, and quality requirements. The Construction Specifications Institute (CSI) has build up the following standard MasterFormat numbering system that includes the following

Technical Specification Divisions.
CSI Technical Specification Division Numbers

Division 2 - Site Work
Division 3 - Concrete
Division 4 - Masonry
Division 5 - Metals
Division 6 - Wood and Plastics
Division 7 - Thermal and Moisture Protection
Division 8 - Doors and Windows
Division 9 - Finishes
Division 10 - Specialties
Division 11 - Equipment
Division 12 - Furnishings
Division 13 - Special Constriction
Division 14 - Conveying Systems
Division 15 - Mechanical
Division 16 - Electrical

The Construction Specification Institute (CSI) dissects each Division into Section Numbers by means of three digits and a Standard Format. The following demonstrates a portion of the section numbers for Division 02.

SECTION 02200 Earthwork
SECTION 02210 Grading
SECTION 02220 Excavating, Backfilling and Compacting
SECTION 02300 Tunneling
The CSI Technical Specification Part Numbers are included in each Specification Section
inside a Division. Each Specification Section have three PARTS in the following order.


A. Subsoil and Topsoil materials

A. Section 02050 - Demolition
B. Section 02100 - Site Preparation
C. Section 02140 - Dewatering

A. ANSI/ASTM C136 - Method for Sieve Analysis of Aggregates.
B. ASTM D2487 - Classification of Soils for Engineering Purposes.

A. Submit Cofferdam Design Drawings with engineer’s seal.
B. Submit 10 pound sample of each type of soil in an air-tight container to test lab.

A. Store and protect materials under




The Contractor has to find out whether there are any unexpected or nonstandard characteristics that may affect the cost. Supply a copy to subcontractors and suppliers if requesting price quotations.
