NRM, IPMS, and Cost Planning Flashcards
What is the full title of NRM 1?
NRM 1, Order of cost estimating and cost planning for capital building works
What is the full title of NRM 2?
NRM 2, Detailed measurement for building works
What is the full title of NRM 3?
NRM 3, Order of cost estimating and cost planning for building maintenance works
What edition is NRM 3?
1st edition
What edition is NRM 2?
1st edition
What edition is NRM 1?
3rd edition
What is the difference between NRM 1, NRM 2, and NRM 3?
You would use NRM 1 for estimating and cost planning during the early stages of construction projects, while the NRM 2 is used for pricing, tendering, and formal measurement during the construction phase.
What is the elemental method of estimating
Breaking down a project into key components/elements and assigning costs to each, providing a detailed cost breakdown/estimate.
List the group elements used to develop an order of cost estimate as per NRM 1
0 - Facilitating works
1 - Sub-structure
2 - Super-structure
3 - Internal finishes
4 - Fittings, furnishings and equipment
5 - Services
6 - Pre-fabricated buildings and building units
7 - Work to existing buildings
8 - External works
9 - Main contractor’s preliminaries
10 - Main contractor’s overheads and profits
What does IPMS stand for?
International Property Measurement Standards
What are the key differences between how NIA is calculated under NRM and IPMS?
IPMs includes areas that NRM doesn’t, such as lift lobbies, window reveals (internal dominant face), piers, and columns
Define Internal Dominant Face
The inside finished surface comprising more than 50% of the floor to ceiling height for each IDF wall section
Do clients tend to prefer NRM or IPMS?
Client’s tend to prefer NRM as IPMS includes for unusable areas such as lift lobbies, as far as the client’s viability studies are concerned.
Why does the RICS recommend the use of IPMS?
Because it’s standardised
What is the structure of a cost plan?
Cover, Contents, Executive Summary, Elemental Breakdown, Area Schedule, Assumptions and Exclusions, Drawing Register
What are some typical assumptions you might make in a cost plan?
- Clarify the base date that the cost plan is based on
- Assume the area schedule can be relied on or drawings to scale
What are some typical exclusion you might make in a cost plan?
- VAT
- Professional, Planning and Building Control fees
- Archaeology and unexploded ordinance
Why do you exclude VAT?
Because the amount of VAT each client pays on each project differs.
What sources of cost data are there?
BCIS, SPONS, Benchmarking, Market Testing
What does TPI stand for?
Tender Price Index
When would you use TPI?
- Cost Forecasting,
- Assessing Inflation Impact
- Historical Cost Analysis
What does BCI stand for?
Building Cost Index
What is the BCI?
A statistical measure used to track changes in construction costs over time, reflecting variations in labour, materials, and indirect costs across different regions and economic conditions.
How do you apply the TPI?
You divide the current TPI over the base or historical TPI and then multiply that by the bas or historical TPI
Define TPI
A statistical measure that specifically tracks changes in tender prices submitted by contractors for construction projects over time.
What is the purpose of an Order of Cost Estimate?
To establish if a proposed project is affordable and to establish a realistic cost limit for the project.
What information is required to produce an Order of Cost Estimate?
- Site location
- Floor area / functional area
- Sustainability requirements
- Quality requirements
- Enabling works requirements
- Restraints
- Site conditions
- MEP requirements
- Indicative programme
What information is required from the architect to produce an Order of Cost Estimate?
- Schedule of areas
- Floor plans / elevations
- Advice on likely planning constraints
What information is required from the M&E Engineer to produce an Order of Cost Estimate?
- Design intent
- Advice on adequacy of utility service connections
What information is required from the structural engineer to produce an Order of Cost Estimate?
- Advice on probable ground conditions
- Indicative design intent
What are the main constituents of an Order of Cost Estimate?
- Facilitating works
- Building Works
- Main Contractor’s Preliminaries
- Project/Design Fees
- Other development costs
Risk allowances (design development, construction, employer change, employer other) - Tender inflation estimate
- construction inflation
Define facilitating works
Specialist works that need to be completed before any building works can commence
What are the three methods used to measure building works for an Order of Cost Estimate?
- Floor Area Method
- Functional Unit Method
- Elemental Method
What is the Floor Area Method? (Order of Cost Estimating)
GIA is multiplied by an approximate cost/m2
What is the Functional Unit Method? (Order of Cost Estimating)
A method whereby the cost per functional unit is multiplied by the number of functional units.
When might you use the Functional Unit Method?
When calculating the cost of constructing a hospital by calculating the cost per bed, allowing for comparison between different hospital projects of varying sizes
