Order of cost estimating and elemental cost planning
6. SFCA and NRM The titles of these documents indicate their purpose:
The SFCA sets out how to analyse the cost of a project into elements.
The NRM sets out how to present and develop a cost plan as the design develops.
7. SFCA and NRM These two processes are the beginning and the end of the cycle of cost information that flows through a procurement process.
The starting point for an elemental order of cost estimate is cost analyses of previous projects.
The starting point for a cost analysis is the costing documents from a procurement process.
There is clearly a chicken and egg relationship.

9. Flow of cost information
10. SFCA and BCIS The SFCA, and indeed BCIS, were developed to facilitate the move from ‘costing a design, to designing to a cost’
For that you need elemental costs
An element is ‘A major physical part of a building that fulfils a specific function, or functions, irrespective of its design specification or construction.’
11. SFCA The SFCA defines the Elements and provides instructions for analysing the costs of a project into Elements and defines the ancillary project information needed to interpret it.
It defines the purpose of a cost analysis as ‘to provide data that allows comparisons to be made between the costs of achieving various building functions in a project with those of achieving equivalent functions in other projects. It is the analysis of a building in terms of its elements.’
12. SFCA The key point is that the content of the functional Elements as defined in the SFCA should not change with the design or specification.
13. Elemental cost analyses Why are elemental costs useful?
Because they can provide a basis for providing a client a robust estimate based on very little information at a level that helps define the assumption that you have made
And can be based on:

2000m2 offices
Canteen for 200 people
300m2 gallery space
Auditorium for 300 people
Two shops

16. NRM The NRM:
provides a structured basis for preparing ‘order of cost estimates’ and ‘elemental cost plans’ including all the costs and allowances forming part of the cost of the building to the client but which are not reflected in the measurable building work.
17. NRM Order of cost estimate:
The determination of possible cost of a building early in design stage in relation to the employer’s fundamental requirements. This takes place prior to preparation of full set of working drawings or bill of quantities and forms the initial build up to the cost planning process
18. NRM Elemental Cost Plan:
The critical breakdown of the cost limit for the building into cost targets for each element of the building. It provides a statement of how the design team proposes to distribute the available budget among the elements of the building, and a frame of reference from which to develop the design and maintain cost control.
19. SFCA and NRM So far so good.
The starting point for the NRM was the SFCA elemental definitions, which define the physical building.
The practical issues involved in pricing a design as it develops and in presenting the rules the NRM means that the presentation of the two documents are different. However some effort was made to ensure that the two structures are compatible
20. So what are the differences The differences are:
NRM covers the non-physical aspects of a project that the client may require as part of his overall budget for the project, while the SFCA relates to the physical construction and contractors charges.
Pragmatic changes to presentation and allocation
Different coding system.
21. NRM Guidance on pricing the non-physical aspects of a project that the client may require as part of his overall budget for the project eg:
Main contractors preliminaries
Contractors overheads and profit
Project/design team fees
Other development/project costs, eg insurance, planning fees, decanting and Section 106 agreement contributions
Risk allowances
Inflation
Value Added Tax
Other considerations eg Capital Allowances, Land remediation allowances and Grants
22. Presentation and allocation NRM also introduction some pragmatic changes to the familiar SFCA list of elements:
The purely presentational issues
Introduction of designed elements and sub-elements
Splitting Facilitating works and External works
Introducing non-element cost category for off-site constructed buildings
Practical pricing issue relating to procurement that moves the structure away from elements towards packages.
Editorial changes
23. presentational issue NRM presents the rules in a table with three levels
To reducing the white space in the tables some SFCA sub-elements are presented at level 2 rather than level 3
For example in the SFCA Substructure is an element but is also a group element. In NRM the sub-elements are presented at level 2 and further broken down at level 3.
24. Designed elements At level 3 the structure is expanded to incorporate design and specification eg:
25. External works External works split into:
Work to existing buildings
External works
Facilitating works
26. Off-site construction Complete buildings and building units
Prefabricated buildings – complete buildings
Prefabricated buildings – building units
27. Pricing and packages Practical pricing issue relating to procurement that moves the structure away from elements towards packages eg:
‘Façade retention’ is included with demolitions as it will be procured as part of the demolition package.
‘Work to existing buildings’ covers work all work to existing not just work to adjacent buildings.
Podium slabs forming roofs to basements are included in upper floors
Drainage under the building in substructure
Testing and commissioning of individual service installations separated from installations
28. Coding The SFCA has a numeric/alpha/numeric coding eg 2F1 External windows
The NRM structure uses a numeric/numeric/numeric coding eg
2.6.1 External windows
This will help to differentiate between the two.
29. The circle of cost information Project costs reported in the format of the NRM measurement rules can easily form the basis of the and SFCA elemental cost analysis.
Elemental cost analyses provides the initial costs to inform an elemental order of cost estimate before the design exists. This can be developed following the NRM guidance as the design develops and, where the resultant cost plan forms the basis of the contract sum analysis, it can be re-analysed into functional Elements.
