Cost Plan Stage 3 Level Flashcards
RIBA stage?
Formal cost plan RIBA Stage
1 2: Concept Design
2 3: Spatial Coordination
3 4: Technical Design
NRM 1, pg 54:
There are several formal cost planning stages, aligned with RIBA Stages 2, 3 and 4, and contractor engagement and OGC Gateways 3A and 3B for a building project. The client should approve the cost plan on completion of each RIBA Stage before authorising commencement of the next Stage.
Formal cost plan 1 is prepared once the scope of work is fully defined and key criteria specified, but no detailed design has commenced.
Formal cost plan 1 will provide the frame of reference for formal cost plan 2.
Likewise, formal cost plan 2 will provide the frame of reference for formal cost plan 3.
Neither formal cost plans 2 nor 3 involve the preparation of a completely new elemental cost plan: they are progressions of the previous formal cost plans developed through the cost checking of cost significant components and cost targets as more design information and information about the site becomes available.
Information required/expected?
The information base of the building project continues to expand during the RIBA Stages 2, 3, 4 and OGC Gateways 3A, 3B and 3C as more project and design team, main contractor and
specialist subcontractor engagement and client interaction take place.
A list of the key information to enable preparation of formal cost plans is included in Appendix C.
pg 50:
Outcome: All design information required to manufacture and construct the building, or built asset, completed.
Stage 4 involves the preparation of all information required to manufacture and construct
a building or built asset. The core documents at the start of Stage 4 are the responsibility
matrix, the information requirements and the Stage 4 design programme, which will be heavily
influenced by the procurement strategy.
Tasks: The quantity surveyor/cost manager is to:
1 Update formal cost plan 2 iteratively – to a level of detail defined by the procurement
strategy (establishing formal cost plan 3). Formal cost plan 3 becomes a pre-tender cost
estimate (where the procurement strategy does not require either a full bills of quantities or
pricing schedules).
2 Identify risk allowances and uncertain areas where either provisional sums, prime cost sums
or prime cost prices are required.

Measurement format expected? (eg GIFA, M2, Functional Unit)
This third formal cost plan stage is based on technical designs, specifications and detailed
information for construction. Formal cost plan 3 is a progression of formal cost plan 2.
It is developed by cost checking of cost-significant cost targets for elements as more
detailed design information is made available from the design team.
– Cost plan 3 will provide the frame of reference for appraising tenders.
– The key information from the client and other project and design team members to
enable preparation of formal cost plan 3 is set out in Appendix C.
– The cost checks should be carried out against each pre-established cost target.
– Quantities for building works should be determined in accordance with Part 4 (group elements 1
to 8).

NRM 1: ORDER OF COST ESTIMATING AND COST PLANNING FOR CAPITAL BUILDING WORKS
– Where insufficient design information is available to quantify building works in accordance
with the rules of measurement for elemental cost planning, then the quantity measured
should be the GIFA.

pg 72,
The tabulated measurement rules are based on four principal levels. Levels 1 to 3 in the rules
are headings under which actual work items (i.e. group element, element and sub-element) are
allocated. Level 4 is the rules of measurement for components.
