• reports on other statutory consultations
• existing Health and Safety Files, client’s health and safety policy documents
• functional nature of the building(s) (e.g. kind and number of units) and
accommodation requirements
• schematic layout of the building (or more developed design as appropriate)
• specific requirements as to forms of construction, materials, services,
finishes, equipment, etc.
• specification information, probably including performance specifications
• room data sheets
• equipment and fitting schedules
• details of special programming requirements (e.g. phased completion)
• contract data or special requirements (e.g. named subcontractors, ‘as-built’
information)
• requirements concerning contractor’s design liability, insurance cover,
design team, requirement to use employer’s designers, etc.
• clear statement of the extent of information and detail to be included in the
Contractor’s Proposals
• content and form of the contract sum analysis
• if JCT DB11 is to be used, information related to supplementary provisions.
It is generally accepted that too specific an approach to design and constructional
matters, or the specifying of proprietary systems and materials, may reduce the
contractor’s design liability in the event of a failure.
Contractor’s Proposals
These will be in direct response to the Employer’s Requirements. Architects
acting as consultants to a contractor client will first need to check the information
provided to establish whether it is adequate. While contracts like the JCT DB11
absolve the contractor of any liability of the adequacy of the design or other
information in the Employer’s Requirements, this is subject to the requirement
that any inadequacy found is brought to the notice of the employer immediately.
Therefore a query list is often necessary to obtain clarification on matters of
conflict or omission.
Submissions sometimes take the form of an A3 brochure and typically include
the following:
• design drawings (e.g. site layout, floor plans, elevations, principal sections,
some detailed drawings, landscaping)
• structural details (e.g. foundation and structure general arrangement
drawings)
• mechanical services (e.g. layouts of ducts, pipe runs, schematic indications
for all systems)
