The document discusses quality control procedures for construction projects. It outlines that designers, manufacturers, and contractors must ensure minimum quality standards are met. Quality inspectors should inspect all construction processes according to the contractor's method statements and contract documents. The document also discusses ISO standards, quality assurance programs, and sources of technical information for quality control procedures in architecture, engineering, site management, and inspection.

12. QUALITY CONTROL
In practice Building Control Officers (BCOs)and
inspectors are prepared to provide some advice
where they can and if they visit.
Large Private Developments –Sites where
main contractor is client
These sites are often those being developed by a
large private house builder.
The house builder/developer will often have a
project manager and site manager.
Larger sites-assistant site managers who have
responsibility for quality control. 12/15/2020SNJV432@GMAIL.COM 12

13. QUALITY CONTROL
•BCOs and inspectors from the Local
Authorities are prepared to provide some
advice where they can and if they visit.
• However, it is not their role.
• Often, the emphasis, on sites of this nature,
is on getting the work done as quickly as
possible to the minimum standard required
to satisfy the warranty provider and possibly
the BCO.
• This emphasis has developed as a result of
commercial pressures on time and finance
and the lack of skilled tradesmen. 12/15/2020SNJV432@GMAIL.COM 13

14. QUALITY CONTROL
Large Private Developments
(where main contractor is not
client)
1. The project manager/site manager for

16. QUALITY CONTROL
Under Design & Build contracts:
• Most of the responsibility for quality
control of design, specification and
construction rests with the main
contractor.
• Under many forms of Design & Build
contract the client is able to check build
quality through the use of:
1. their own Clerk ofWorks
2. third-party inspection service providers.
