Stage 1 > Preparation and Brief: Supplementary Material: 1/SM2
• ‘builder’s work’ drawings are for the architect to arrange, making sure
that requirements for holes, shafts, access, insulation, etc. are properly
coordinated and integrated into the design
• ‘coordination drawings’, where commissioned, should show detailed layouts
and their relationship to plant rooms, spaces, structure, etc.
• ‘installation drawings’ (or ‘shop drawings’) are produced by the subcontractors
or suppliers, and may be expected to show only general lines of pipework,
fabrication and equipment installation details for comment by the engineering
services consultant prior to fabrication or installation.
It is normally the architect’s responsibility to coordinate and integrate the work
of consultants and specialists into the overall design. To this end, architects will
need to inspect drawings submitted by specialists (refer to Stage 5). However,
contract documents should clearly place the responsibility for coordination of
work being carried out on site with the main contractor.
Sub-consultants
If the architect is to appoint sub-consultants directly, great care must be taken
to check their competence and resources with respect to health and safety
regulations and their PI insurance provisions. The RIBA Sub-consultant Agreement
2010 (2012 revision) should be used wherever possible.
Information manager
Refer to 1.5.5.2.
Consultant team roles and responsibilities
It is good practice to table the Design Responsibilities Matrix at the earliest
opportunity. This identifies all the main project activities and specifies which
consultant will have prime responsibility for which activity. It can also identify
whether there are any secondary roles. Its prime objective is to clearly set out
who is doing what, which may then lead to any gaps or overlaps in services being
identified. This matrix needs to be shared with the client and agreed and signed
off by the whole team.
Cost consultant
The cost consultant can assist the architect in assessing economic site use and
advising on procurement methods. They can analyse Cost Information from
other similar projects, local levels of building costs and cost trends, etc., and can
judge whether the client’s budget is realistic and compatible with other stated
requirements.
