Introduction

Successful and cost-effective construction relies on appropriate communication of a project design by the architect/engineer (A/E) to the contractor and other project participants. From project conception through design and construction to facility management, effective communication of the project requirements depends largely on having complete and coordinated construction documents.

The responsibilities of the participants comprising the design team are determined by the project delivery method used. In the design-bid-build, design-negotiate-build, construction management, and owner-build methods of project delivery, the A/E executes the design phases and delivers to the owner the documents according to the owner-A/E agreement. Design-build project delivery differs in that the A/E is employed by the design-builder, and the design-builder executes both the design and construction. The term A/E will be used to identify the design professional responsible for the project design and construction documents, regardless of the project delivery method used.

This practice guide is based primarily on the traditional design-bid-build delivery method and variations are indicated for other delivery methods.

The term contractor might also refer to a construction manager as contractor (CMc) or a design builder.

Many product decisions are made throughout the development of the contract documents. Product representatives can be a part of those decisions by providing technical assistance to the A/E, owner, or contractor in the early stages of a project and continuing the assistance through the development of the contract documents. Product representatives should be familiar with the overall concepts of drawings and specifications and understand the implications of contract modifications. Thorough knowledge of all aspects of the represented product is essential when assisting the A/E with the development of the documents used for construction. Product representatives should present themselves to the A/E as technical experts and resources on the proper use and incorporation of reference standards, specifications, testing and certification, and applicable codes. The ability to review documents and advise the A/E on a cost-effective method of installation, or a new product that would contribute to the project’s success, is a valuable service and can build credibility.

Construction documents define the rights of, responsibilities of, and relationships among the parties. Of these documents, the Agreement and the General Conditions of the Contract have been developed by professional associations such as the American Institute of Architects (AIA), the Engineers Joint Contract Documents Committee (EJCDC), and the Design-Build Institute of America (DBIA) into standard documents. Several different standard documents have been published by these organizations for the various project delivery methods and basis of payment customarily used for construction. The advantage of a standard document is that it provides familiarity through repeated use and also that this repeated use has resulted in clear and well-coordinated documents. This standardization has been extended to the project specifications and drawings as well.

The Construction Specifications Institute’s (CSI) and Construction Specifications Canada’s (CSC) 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.

Similarly, SectionFormatTM and PageFormatTM set up standard formats for the presentation of requirements within a specification section and on each specification page. UniFormatTM provides a standard for organizing information on construction systems, assemblies, and elements. The U.S. National CAD Standard for Architecture, Engineering, and Construction (NCS), including the Uniform Drawing System (UDS), provides a standard for defining and locating information on the drawings, including the identification of standard symbols, abbreviations, and notations. Through the use of such standardization, information can be placed properly in a predetermined location for each construction project, thereby making the task of using the documents much easier.

Specifications can be more easily coordinated with the drawings, specifications sections can be coordinated with each other, and A/E consultants can correctly integrate their work with less effort and error. It is not practical to include sufficient notes on construction drawings to describe in complete detail all of the product qualities and installation methods. Separate written descriptions, referred to as specifications, more effectively communicate this type of information.

The drawings and specifications are complementary. Proper methods of writing specifications or developing master guide specifications must be employed. The information must be clear to the user and presented in a concise manner, and it must also be technically correct and complete.

Specifying methods include descriptive, performance, reference standard, and proprietary. The A/E or specifier must understand the preparation of procurement documents and have an understanding of contract conditions including construction insurance, warranties, and bonds. The preparation of conventional specifications, as well as particular procedures such as specifying for the purchase of goods or for public agencies or the preparation of shortform specifications, requires an understanding of construction documents.

Construction documents are defined as the written and graphic documents prepared or assembled by the A/E for communicating the project design for construction and administering the construction contract. Construction documents are also used to obtain permits from the authority having jurisdiction (AHJ). Providing complete, coordinated, and easily readable construction documents that demonstrate code compliance can assist in problem-free AHJ reviews and inspections.

A standardized approach to the location of project subject matter for both written and graphic documents greatly simplifies the retrieval of information and reduces the possibility of conflicts, discrepancies, errors, and omissions. Written project requirements are organized in an orderly fashion, following the project manual concept. A properly assembled project manual with each document in its assigned location will facilitate checking and coordination. Likewise, a drawing set organized in a standard format with uniform location for information will be easier to coordinate with the project manual and itself.

Another important principle governing the production of construction documents is that each document, written or graphic, has a specific purpose and should be used for that purpose. Each requirement should be stated only once and in the correct location. Information in one document should not be repeated in other documents.

Whether a project is simple or complex, the basic concepts for preparing, organizing, and coordinating construction documents are applicable. Construction documents include two major groups of documents: procurement documents and contract documents.

Preface

Introduction to the Practice Guide Series

Beginning with the publication of the first Manual of Practice (MOP) in 1967 continuing through the publication of its successor document, the Project Resource Manual (PRM), it has been the intent of the Construction Specifications Institute (CSI) that these publications embody accepted standards for the preparation of construction specifications and project manuals, and a detailed source of information on quality documentation for the life cycle of a facility.

Through these publications, CSI has sought to aid owners, designers, specifiers, contract administrators, contractors, construction product representatives, and facility managers in the performance of their jobs.

In 2008, CSI began an effort to update the knowledge formerly contained in the MOP and PRM to present it anew and ensure its continued relevance. As with the earlier collections of this knowledge, the intent is to provide an authoritative resource on the organization, preparation, use and interpretation of construction documents, encompassing the entire life cycle of a facility from conception through facility management.

To accomplish this update CSI established the Practice Guides Task Team. One of the task team charges was to organize the presentation of this information into modules to support areas of practice where CSI currently offers certificates and certifications, such as Project Delivery addressed by the Construction Documents Technology (CDT) certificate, Specifications, addressed by the Certified Construction Specifier (CCS) certification, Contract Administration addressed by the Certified Construction Contract Administrator (CCCA) certification, and Product Representation addressed by the Certified Construction Product Representative (CCPR) certification, as well as other areas of practice for which education and certification may be developed.

To keep current with changes in the industry, the Task Team also reviewed other CSI documents and standards, and updated references to them that appear in the Practice Guides. A similar effort was made to incorporate changes in contract documents produced by The American Institute of Architects (AIA) and the Engineers Joint Construction Documents Committee (EJCDC), and to introduce the new standard contract documents developed by the ConsensusDOCS Coalition.

The Task Team also recognized the growing impact of “green” or sustainable practices on the subject matter contained in the Practice Guides. Each Practice Guide now addresses the topic of sustainable practice to some degree while a more detailed examination of the topic is planned for a future Sustainable Practice Guide.

Two other topics that have had an impact on the Practice Guides are: Building Information Modeling (BIM) and Integrated Project Delivery (IPD). The growing impact of BIM on the practice of specification writing and its potential impact on quality documentation made a discussion of this topic imperative. Likewise IPD has grown in importance over the past several years and has had an impact on the way practitioners relate to the process of creating and interpreting construction documents.

The Practice Guide Series is not intended to be composed of static documents but to be a living set of guides with the capacity to change and be updated as the construction industry changes around them. The input of users of this Series will be critical to the future updating of the Series and the authors and reviewers welcome feedback from users.

Description of The CSI Construction Specifications Practice Guide

The CSI Construction Specifications Practice Guide describes the process needed to effectively communicate a project design from the architect/engineer to the contractor, as well as other participants involved in the process of project conception, design, construction, and operation. The successful communication of a project design depends on the creation of a complete and coordinated set of construction documents both graphical and written. The CSI Construction Specifications Practice Guide serves as a guidebook to the preparation, organization, and coordination of construction documents and focuses on the written description of a project and how that description relates to the other construction documents. The CSI Construction Specifications Practice Guide also describes the best practices for product selection and defines the roles and responsibilities of the various parties to the process. Whether the reader is a seasoned practitioner or just getting started in creating or using written construction documents, the CSI Construction Specifications Practice Guide provides the information needed to enable effective communication among the various parties involved in a construction project.

Practices

1.1 Project Manual Concept

The documents commonly referred to as the specifications normally contain much more than that name implies. The procurement requirements, contracting forms, and conditions of the contract are usually included, but they are not specifications. In most cases, these are prepared by, or in coordination with, the owner and the owner’s legal counsel and insurance adviser. This information, along with the specifications, is, in fact, a collection of certain written construction documents and project requirements whose contents and functions are best implied by the title “Project Manual.” The project manual concept provides an organizational format and standard location for all of the various construction documents involved. For efficient coordination, document and section titles and their sequence of use should be the same for each project. With different methods of construction procurement, some documents become unnecessary. For example, in the owner-build delivery method and with negotiated contracts, bidding requirements are not applicable. shows an example of the recommended order of information and documents in a project manual. Separate volumes of the project manual are necessary when the number of pages makes them impractical to bind together in a single volume. Addenda and modifications are difficult to add to the bound project manual and are often compiled in a separate volume. Separate volumes can also be used for multiple contract construction projects.
