The Construction Project Information Committee is an advisory group, comprising representatives of major UK construction industry institutions, which provides best practice guidance on the content, form and preparation of construction production information, and disseminates this throughout the industry.
CPIC started as the Building Project Information Committee (BPIC) established in February 1987 by the RIBA, RICS, ACE, CIBSE and ICE. BPIC succeeded the Co-ordinating Committee for Project Information (CCPI) which had been established to provide guidance on efficient preparation of project specifications and production drawings. [1]
Research has shown that many problems on site are caused by poor or missing production information.[ citation needed ] The evidence shows that improvements in the quality of production reduce the incidence of site quality problems and lead to significant savings in the cost of construction work. Modern CAD systems can contribute greatly to the quality and clarity of drawn production information and, if used in a collaborative way by the whole design team, will result in benefit for all the concerned: clients, designers and constructors. The Avanti approach had showed that the use of CPIC materials would improve the quality and reduce the costs of construction projects.
In recent years, CPIC has been a key player in the development of common industry approaches to building information modelling (BIM).
Effective communication of high quality production information between designers and constructors is essential for the satisfactory realisation of construction projects. This is addressed by the CPIC code of procedure, the essential reference on production information, which sets out principles and procedures based on the use of computers and offers a pragmatic approach in providing guidance to users of widely used 2D CAD systems. The guidance on specification is also based on the use of the dominant computer systems.
In a move that reinforces the close relationship between the drawings and specification, the code combines the original drawing and specification documents into a single guide. This has been extended to cover use of CAD and to take into account the use of schedules of work. It provides pragmatic guidance on use of drawings, specifications and schedules of work and the methods used to co-ordinate the information contained within. Key themes that appear in the code are standardisation, information re-use and information management.
The starting point for the guidance in the code is the creation of standards. From project inception, all parties should agree the methods and protocols of exchanging information. This includes not just CAD and specification, but also spreadsheets and word processing documents. Standardisation removes any barriers to exchange and improves the communication process. BS 1192 relies heavily on the guidance in this code.
Uniclass is a classification scheme for the construction industry, the full name of which is "Unified Classification for the Construction Industry". It is intended for organising library materials and for structuring product literature and project information. It incorporates Common Arrangement of Work Sections (CAWS) and Electronic Product Information Co-operation (EPIC), a new system for structuring product data and product literature.
Uniclass comprises 15 tables, each of which represents a different broad facet of construction information. Each table can be used as a "stand alone" table for the classification of a particular type of information, but, in addition, terms from different tables can be combined to classify complex subjects.
CAWS defines an efficient and generally acceptable arrangement for specifications and bills of quantities for building projects. It consists of a set of detailed work section definitions, all within a classification framework of Groups and Sub-groups. The CAWS classification down to the level of work section titles forms one of the 15 tables of the Uniclass classification scheme.
Different titles often mean different things in different industry documents and to different groups of people. CAWS provides the detailed definitions in order to reduce needless variations and conflicts between documents and even within the same document. In practice this means concentrating on the boundaries to ensure that gaps and overlaps between sections are eliminated.
CAWS includes about 360 work sections. They are derived from close observation of current practice, following the pattern of sub-contracting in the industry.
An architect is a person who plans, designs and oversees the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose. Etymologically, the term architect derives from the Latin architectus, which derives from the Greek, i.e., chief builder.
British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the national standards body (NSB) for the UK. The BSI Group produces British Standards under the authority of the charter, which lays down as one of the BSI's objectives to:
Set up standards of quality for goods and services, and prepare and promote the general adoption of British Standards and schedules in connection therewith and from time to time to revise, alter and amend such standards and schedules as experience and circumstances require.
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component. The drawings are linked together by a master drawing or assembly drawing which gives the drawing numbers of the subsequent detailed components, quantities required, construction materials and possibly 3D images that can be used to locate individual items. Although mostly consisting of pictographic representations, abbreviations and symbols are used for brevity and additional textual explanations may also be provided to convey the necessary information.
In industry, Product Lifecycle Management (PLM) is the process of managing the entire lifecycle of a product from its inception through the engineering, design and manufacture, as well as the service and disposal of manufactured products. PLM integrates people, data, processes and business systems and provides a product information backbone for companies and their extended enterprises.
The Construction Specifications Institute (CSI) is a United States national association of more than 8,000 construction industry professionals who are experts in building construction and the materials used therein. The institute is dedicated to improving the communication of construction information through a diversified membership base of allied professionals involved in the creation and management of the built environment, continuous development and transformation of standards and formats, education and certification of professionals to improve project delivery processes, and creation of practice tools to assist users throughout the facility life-cycle. The work of CSI is currently focused in three areas being standards and publications, construction industry professional certifications, and continuing education for construction professionals.
MasterFormat is a standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. and Canada. Sometimes referred to as the "Dewey Decimal System" of building construction, MasterFormat is a product of the Construction Specifications Institute (CSI) and Construction Specifications Canada (CSC). It provides a master list of Divisions, and Section numbers with associated titles within each Division, to organize information about a facility’s construction requirements and associated activities.
CAD Standards are a set of guidelines for the way Computer-aided drafting (CAD), or (CADD) Computer Aided Design and Drawing, drawings should appear, to improve productivity and interchange of CAD documents between different offices and CAD programs, especially in architecture and engineering.
ISO 13567 is an international computer-aided design (CAD) layer standard.
Uniclass 2015 is a unified classification system for all sectors of the UK construction industry. It contains consistent tables classifying items of all scales, from entire systems such as a railway to individual product items such as anchor plates, flue liners or LED lamps.
A steel detailer is a person who produces detailed drawings for steel fabricators and steel erectors. The detailer prepares detailed plans, drawings and other documents for the manufacture and erection of steel members used in the construction of buildings, bridges, industrial plans, and nonbuilding structures.
Submittals in construction management are shop drawings, material data, samples, and product data. Submittals are required primarily for the architect and engineer to verify that the correct products will be installed on the project.
A shop drawing is a drawing or set of drawings produced by the contractor, supplier, manufacturer, subcontractor, consultants, or fabricator. Shop drawings are typically required for prefabricated components. Examples of these include: elevators, structural steel, trusses, pre-cast concrete, windows, appliances, cabinets, air handling units, and millwork. Also critical are the installation and coordination shop drawings of the MEP trades such as sheet metal ductwork, piping, plumbing, fire protection, and electrical. Shop drawings are produced by contractors and suppliers under their contract with the owner. The shop drawing is the manufacturer’s or the contractor’s drawn version of information shown in the construction documents. The shop drawing normally shows more detail than the construction documents. It is drawn to explain the fabrication and/or installation of the items to the manufacturer’s production crew or contractor's installation crews. The style of the shop drawing is usually very different from that of the architect’s drawing. The shop drawing’s primary emphasis is on the particular product or installation and excludes notation concerning other products and installations, unless integration with the subject product is necessary.
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard.
Common Arrangement of Work Sections (CAWS), first published in 1987, is a construction industry working convention in the UK. It was designed to promote standardisation of, and detailed coordination between, bills of quantities and specifications. It is part of an industry-wide initiative to produce coordinated projects information. CAWS has been used for the arrangement of the National Building Specification, the National Engineering Specification and the Standard Method of Building Works.
Avanti was established by the UK Department of Trade and Industry in 2002 to formulate an approach to collaborative working in order to enable construction project partners to work together effectively. The project was promoted by the Department of Trade and Industry with the support of most of the largest UK firms in the construction industry. Avanti also involved the International Alliance for Interoperability (IAI), Loughborough University and Co-Construct, a network of five construction research and information organizations.
A drafter is an engineering technician who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc. Drafters use computer software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings. Drafters operate as the supporting developers and sketch engineering designs and drawings from preliminary design concepts.
An architectural drawing or architect's drawing is a technical drawing of a building that falls within the definition of architecture. Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building contractor to construct it based on design intent, as a record of the design and planned development, or to make a record of a building that already exists.
Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation around the building. It is a powerful tool that helps analyze complex systems. These drawings are often a set of detailed drawings used for construction projects; it is a requirement for all HVAC work. They are based on the floor and reflected ceiling plans of the architect. After the mechanical drawings are complete, they become part of the construction drawings, which is then used to apply for a building permit. They are also used to determine the price of the project.
NBS is a UK-based business providing construction specification information used by architects, engineers and other building professionals to describe the materials, standards and workmanship of a construction project. It was launched in 1973 and its information is now used by over 5000 offices.
