CONSTRUCTION SPECIFICATIONS

Teammates: Diego García, Rafael García, Yessica Martínez, Juan De Dios Mejía, Roberto Mendoza and Haziel Zamora

Construction Specifications Describe the required: Materials, Execution & Quality of performance Incorporate various standards, codes and other publications Provide guidance on the full requirements of the contract

Clear Concise Correct Complete

Methods of specifying Descriptive. Specifies properties of materials and methods of installation without using proprietary names.

Performance. Specifies the required results, the criteria by which the performance will be judged, and the method by which it can be verified.

Reference Standard. Specifies product or processes by established standards. Proprietary. Specifies actual brand names, model numbers, and other proprietary information.

Why Specs are important? -

Correct execution

-

Access to ample data is critical to making the right decisions when building.

-

They reduce risk.

-

Specifications are particularly important during the tender process for pricing.

Specifier Specifications may be produced in a variety of ways, depending on individual office practice and, depending on the type of work generally performed, the number of specifications produced and the size of the architect/engineer’s In all instances, someone by choice or assignment will assume the role of specifier and will be responsible for assembling the project specifications.

What´s the Construction Specifications Institute? ●

1948, USA

●

It´s a national association of almost 7,000 experts in building construction and the materials used therein. (CSI webpage, “About Us”)

●

Their objective is to upgrade “building information management” and “education of project teams”in order to improve facility performance. (CSI webpage, “Mission”)

Construction Standards - Guide Formats

CODES MasterFormat®: presents a master list of numbers and titles for divisions and sections, providing a uniform location for administrative, procedural, and product information for any type of construction project. SectionFormat™ and PageFormat™: set up standard formats for the presentation of requirements within a specification section and on each specification page. UniFormat™: It provides a standard for organizing information on construction systems, assemblies, and elements. The U.S. National CAD Standard for Architecture, Engineering and Construction (NCS): provides a standard for defining and locating information on the drawings, including the identification of standard symbols, abbreviations, and notations (CSI, 2011).

Figure 1: Hierarchy of the Formats (CSI, 2011, p.60)

MasterFormat Produced by Construction Specifications Industry (CSI) and Construction Specifications Canada (CSC) “Is a master list of numbers and titles classified by work results” (CMAA, 2014, p.20). First version published in 1963 and this counted with 16 divisions. In 2004 was published a new version with 50 division, is the current one.

MasterFormat Main uses

To organize project specifications, detailed cost information, and other information about requirements, products and activities, during the design and construction phase.(CMMA, 2016, P. 20).

Advantages

●

Improve communication among project groups and among owners, architects, contractors and suppliers.

●

Effective teamwork for all the parties to ensure the correct and timely completion of work. (CSI, n.d)

UniFormat It is a method of arranging construction information based on functional elements, or parts of a facility characterized by their functions, without regard to the materials and methods used to accomplish them.

These elements are often referred to as systems or assemblies (CMAA, 2014, p.20).

UniFormat MAIN USES As a format for estimators to present cost estimates during the schematic design phase

Preliminary project descriptions (PPD)

Performance specifications (CMAA, 2014, p.20) Figure 2: uniformat_calculation (Engineering Toolbox, 2010)

UniFormat HOW IT WORKS AND BENEFITS UniFormat breaks a facility into systems and assemblies that perform a predominating function, without defining the technical solutions to provide these functions. This allows the facility to be priced at the elemental level, allowing design alternatives to be better evaluated, and allows facility performance to be established at the system level as the project design is being refined (CMAA, 2014, p.20).

OmniClass “Standard for organizing all construction information. The concept for OmniClass™ is derived from internationally-accepted standards that have been developed by the International Organization for Standardization (ISO) and the International Construction Information Society (ICIS) subcommittees and workgroups from the early-1990s to the present.” (csiresource)

OmniClass ISO 12006-2: This standard provides a basic structure of information about construction that is grouped into three primary categories composing the process model: 1. 2. 3.

construction resources construction processes construction results.

These are then divided into fifteen suggested “Tables” for organizing construction information. The OmniClass™ Tables correspond to this arrangement of information: ● ● ●

Tables 11-22 to organize construction results Tables 23, 33, 34, and 35, and to a lesser extent 36 and 41, to organize construction resources, and Tables 31 and 32 to classify construction processes, including the phases of construction entity life cycles.
