Stage 4 > Technical Design: Supplementary Material: 4/SM2
4/SM2: Technical Design drawings
Coordinated Project Information
Many problems and delays on site are due to inaccurate or incomplete
information, and it is essential that the tender drawings, specifications, etc., and
any subsequent Technical Design produced, is complete and fully coordinated.
The use of Coordinated Project Information (CPI) is recommended for all projects
regardless of procurement method. The Construction Project Information
Committee (CPIC), a body made up of representatives of the RIBA, RICS, ICE,
CIBSE and the Construction Confederation, has been responsible for providing
best practice guidance on the content, form and preparation of construction
Technical Design and making sure this best practice is disseminated throughout
the UK construction industry. The CPIC publication Production Information: A
Code of Procedure for the Construction Industry provides best practice advice for
this aspect of the procurement process – it can be found on the CPIC website:
www.cpic.org.uk.
The importance of non-adversarial team working has long been recognised.
Current IT technology facilitates such tools as the single project model, which
rely on an integrated team structure and so good information is essential in
maintaining a non-adversarial environment and a successful project.
Structure of drawings
P/SM1 sets out how Technical Design drawings should comprise location
drawings, component drawings and dimensioned diagrams in accordance with
SMM.
Drawings from the structural engineer and the building services engineer
should be structured in a compatible manner despite the fact that, in their
cases, information is likely to come from a number of sources, including specialist
subcontractors and suppliers.
Purpose of drawings
Drawings at this stage are produced for three main reasons:
• because they must accompany a bill of quantities or other tendering
documentation and generally as stipulated by SMM
• because they will later become contract documents
• because they may need to be developed or issued as other ‘necessary
information’ under the building contract to the main contractor when work
on site commences.
