Q

Why is VAT excluded?

A

Because different clients will incur different levels of VAT, and might not be applicable.

15
Q

How is contingency assessed?

A

The amount included should reflect the risks and unknowns specific to the project.
During early estimates when little information is available it is common to include a %
At the end of stage C it is usually 10%
This should reduce as more information becomes available and the unknowns decrease
At the end of Stage E it is usually 5% (2.5% design and 2.5% construction contingency)
It is common to have a higher % for refurbishment work due to the higher level of unknowns and therefore risks

23
Q

How do you take account of location, and why do you need to take account of location?

A

Through the application of location indices

Different market conditions in different locations

Different cost of materials, different wage rates etc – impact on tender levels

24
Q

What does BCIS stand for, and what is it?

A

Building Cost Information Service

Provides construction cost and price information through publications, online services and price books

25
Q

What is a cost plan?

A

Presents the estimated cost into a structural elemental or functional format.

It shows how the design team proposes to distribute the funds available on the elements of the proposed building.

26
Q

What is the purpose of a cost plan?

A

It is used by the cost consultant to control the development of the design.

It identifies the client’s agreed cost limit and how the money is to be allocated to the different parts of the building.

27
Q

What is the difference between a cost estimate and a cost plan?

A

Cost plan is a plan of costs for the works in preparation for turning into a cost report to check against.

Estimate is a forecast of construction cost

28
Q

What is buildability?

A

Harnessing the contractor’s expertise and knowledge during the design stage

29
Q

What are the advantages of buildability?

A

Better programming, sequencing and construction methods – a quicker construction time

Lower capital and life cycle costs

Improved quality in the finished building’s performance and maintenance characteristics

30
Q

What is a wall to floor ratio?

A

This shows the relationship between wall area and floor area

It is used to show the cost efficiency of the building

The lower the ratio the cheaper the building as there is less external wall area per m2 of floor area

31
Q

What is the most efficient shape?

A

A circle BUT this is not the most practical shape as it has a poor lettable floor area – difficult to fit out THEREFORE a square is the best

32
Q

What is the difference between cost and price?

A

Cost is the total of labour, plant, materials and management deployed for a specific activity

Price is the amount a purchaser / client will pay for an item or product – it is cost plus profit

33
Q

What information would you expect the design team to provide at stage D?

A

Detailed design information approaching that of tender documentation.

34
Q

How would you prepare an estimate for M&E works?

A

I would ask an M&E specialist surveyor to undertake the estimate.

For feasibility estimates the M&E amount would be included in the m2/functional unit rate

35
Q

What is GEA?

A

Gross External Area

This is the area of the building measured externally at each floor level

36
Q

What is GIA?

A

Gross Internal Area

This is the area of the building measured to the internal face of the perimeter wall at each floor level

Excludes external open sided balconies, fire escapes, canopies, external walls, fuel stores

37
Q

What is NIA?

A

Net Internal Area

This is the area of usable space measured to the internal face of the perimeter wall at each floor level

Excludes the above and internal structural walls and columns, spaces with headroom less than 1.5m, corridors and circulation space used in common, permanent lift lobbies, toilets, cleaners cupboards, plant rooms

38
Q

Where are all of these defined?

A

The Code of Measuring Practice, 6th Edition, published by the RICS

39
Q

What is the purpose of the Code of Measuring Practice?

A

Provides precise definitions to permit the accurate and consistent measurement of buildings

40
Q

What would you expect the percentage of NIA to GIA / GEA to be?

A

It depends on the type of project being undertaken (school, hospital, office etc…)

If it were an office build I would expect the NIA to GIA to be in the region of 70–85%, where 70% is not good and 85% is excellent.

41
Q

Where do you get cost information from?

A 
In house historic data
Benchmarks
BCIS
Building cost models
SPONS and other price books (Laxtons etc)
Sub contractors and suppliers
42
Q

What do you measure in accordance with?

A

NRM2 (was SMM7)

43
Q

What does NRM2 (SMM7) stand for?

A

New Rules of Measurement 2 – Detailed measurement for building works

(Standard Method of Measurement, Edition 7)

44
Q

What does it do?

A

NRM2 has been developed as a set of detailed measurement rules for the preparation of either bills of quantities or Schedules of Rates for either capital or maintenance projects. It does however deal with the quantification of non–measurable work items, contractor designed works and risks.

45
Q

How do you measure steel under SMM7 – and what other items would you measure in association?

A

Under SMM7 steel is measured in Tonnes.

Other items to measure in association with steelwork include framing erection, permanent formwork, cold rolled purlins and cladding rails, isolated structural member, filing hollow sections, surface preparation, surface treatment and localised protective coating. (G)

46
Q

How do you measure brickwork walls under SMM7 – and what other items would you measure in association?

A 
Under SMM7 brickwork walls are measured in m2.  Other items to measure in association with brickwork include:
Isolated piers,
Isolated casings,
Chimney stacks,
Projections,
Arches,
Brick reinforcement,
Sundry items,
Forming cavity,
Closing cavities
47
Q

When did NRM2 replace SMM7?

A

NRM2 was published in April 2012. It became operative on 1 January 2013 and replaced the Standard Method of Measurement, seventh edition (SMM7) on 1 July 2013. SMM7 should no longer be adopted after July 2013.

48
Q

What is NRM1?

A

NRM1 – Rules for order of cost estimating and elemental cost planning

Published in March 2009 and has been reasonably well received and adopted by the profession. It has since been amended and the second edition was launched by the RICS in 2012

49
Q

What is a Section 106 agreement?

A

They are also referred to as planning obligations
They are typically agreements between local authorities and developers negotiated in the context of granting planning consent

50
Q

What sort of things is the money spent on?

A

Affordable housing

New open space or environmental improvements

New roads and transport capacity

Health and education facilities

51
Q

What is construction to ‘shell and core’?

A

The basic structure, services and envelope of the building AND the fit out of landlord / common areas
E.g. reception, toilets, lifts, cores, base services are terminated at breakout points to floors, life safety services infrastructure

52
Q

What is a CAT A fit out?

A

Also known as a ‘developer’s fit out’
Provides the generic requirements to suit most developers
E.g. life safety elements and basic fittings – suspended ceiling tiles, raised floors, carpet, lighting, power distributed to floor plates

53
Q

What is a CAT B fit out?

A

Overlays the CAT A provision with bespoke elements particular to the needs of the building user to enable the tenant to occupy and use the space
E.g. partitions, power distributed to floor boxes, data cabling, artwork and branding, upgrading CAT A finishes and toilet finishes etc

54
Q

Where could you find the definitions for these?

A

British Council of Offices (BCO) fit out guide

55
Q

What is BWIC?

A

BWIC stands for Builders Work In Connection and is usually set as a percentage of the services cost.
Depending on the size of the job and complexity will determine the percentage of BWIC.
BWIC accounts for any drilling, fixing, cutting etc… that the builders do whilst undertaking the services.
BWIC can be measured in accordance with NRM2 when doing a BOQ’s.

56
