Q

Why would you use cost planning?

A

Cost planning advises a property owner how much a proposed project will cost and when the expected expenses will occur, this is critical info to obtain project financing and whether a project is viable

Q

What are the 3 ways to obtain a cost/m² rate for a new building?

A
  1. Comparable project - comparing to one already complete within your organisation.

Q

What is triangulation?

A

The process of using 2 or more methods in a study to check the results. This can be used to price a project using three different methods to get a good average for costs.

Q

What are the issues using GIFA to get a cost per square meter?

A

GIFA - does not allow for variables of shape, height & quality of a building and these will have a major influence on the QS choice of rate.

Q

What are Accuracy & Consistancy

A
  1. Accuracy implies a closeness of the estimate to the actual value.
  2. Consistency is the measure of how often the accuracy can be relied on.

Q

What 7 tabs should be included in an Elemental Estimate?

A
  1. Ancillary Info - Project & Building details
  2. Elemental Summary - Sub-Totals of Sections
  3. Estimate - Details on pricing
  4. Key Dimensions - External Perimeter, CL, Ceiling heights, GIFA, Roof Area
  5. Opening & Room Schedule - Windows, Doors & Rooms
  6. Assumptions, Exclusions & RFI - Assumptions made to price & Further info required.
  7. Rates - Log of rates used
18
Q

What are two common indices associated with the cost study of buildings

A
  1. Construction Cost Index
  2. Tender Price Index
19
Q

What are common applications for indices?

A
  1. Estimating/Cost Planning
  2. Forecasting
  3. Price Variation Clauses or Fluctuation Clauses
20
Q

What are indices used for?

A

Either for updating historic cost data or for predicting future trends in costs & prices

21
Q

What stages of a project could VE occur?

A
  1. Project Brief Development
  2. During Design
  3. During Construction
22
Q

What are the 3 elements of Value Management?

A
  1. Value Planning - Carried out early in life of project.
  2. Value Engineering - during the detailed design or construction stage.
  3. Value Analysis - Carried out when building is complete.
23
Q

Why would you consider whole life costs in design proposals

A

In most buildings occupancy costs will be more than initial costs.

24
Q

Who usually issues variations to the design?

A

Architect, Engineers, client QS

25
Q

If there is a large omission from a contract what is a contractor entitled to claim for

A

Loss of Profit can be claimed

26
Q

What is the 1st place to take rates from Variations?

A

BOQ

27
Q

What is included in the whole life costs of a building?

A
  1. The initial capital costs, (Land, building)
  2. The operating costs (Utility bills,
  3. Maintenance costs for the buildings lifespan
28
Q

What should a developer consider when deciding on costs of a building?

A
  1. How long until the development becomes profitable
  2. How to finance the project - i.e. investors, bank loan
  3. What rates will be applicable - Water charges, council rates
  4. Cost of the land - and value it will be worth after the building lifespan is over.
  5. Maintenance & security costs
    Future Dismantling & Demolition may be required.
29
Q

What should be considered if a project does not appear viable to develop?

A
  1. Could it be done at a different location
  2. Reducing size of building
  3. Value engineering to reduce the costs of the build
  4. Reduce building costs by making it a passive build, = higher initial costs but reduction in running costs.
30
Q

What equipment costs should be thought about in building life span costs?

A

Cost of running equipment esb/gas etc. but also life span of equipment could be 5 years. In a building expected to last 20 year the equipment will have to be changed 4 times.

31
Q

What is NPV?

A

Net present value, referring to the difference between the value of cash now and the future value of the same cash amount. It is used to determine if projected financial gains for a project will outweigh the present day investment.

32
Q

What is meant by basket of items on (for example) Student Accommodation?

A
  1. The cost of land purchase at todays prices
  2. How much rent to charge
  3. Will there be rent increases
  4. How many students will need to occupy the building to turn a profit?
  5. Maintenance & Upkeep
33
Q

Which is better for Cost data a) Tender Price Data or b) Final Account data?

A

Answer a) Tender Price Data because it is not subject to post contract influences such as variations etc. and is easier data to collect.

34
Q

Why do builders & surveyors need ready access to cost information?

A
  1. Preliminary Estimates.
  2. Estimating/Cost Planning during design.
  3. Contract Estimating
  4. Costing Variations
  5. Settling contractors claims
