Q

What is the purpose of a designers risk register?

A

used by the lead consultant to identify early all risks within the project, assess them and communicate to all relevant parties. Hazards to be designed out in design stage, if not mitigated. examples - Red - lack of pre-con information, fragile roof lights , dust production. Amber =internal manholes in circulation areas, changes in floor levels causing trip, heavy elements. Green = adequate access, half board sizes, edge production.

Q

What is the RIBA Plan of Works

A

A - Industry standard for the different phases of a project. Used to identify payment and personal requirements

0 - strategic definition - Business case &brief
1 - preparation and brief - Project execution plan
2 - concept design - outline design &specs
3- spatial coordination - engineering info, change control
4- technical design - finalise designs
5- construction
6-handover - rectify defects
7 - in use - FM

29
Q

What is Project execution plan _ what is included ?

A

sets out strategy for managing a project

  • who does what and how
  • polices procedures and priorities
30
Q

What stages are there in BS 7000-4 Guide to managing design in construction?

A
  1. Conception, 2. Feasibility, 3. Realisation, 4. Operation, 5. Termination.
31
Q

What is a specification ?

A

Describes materials and workmanship. No info on costs, qauntities or drawings. Require ready alongside BoQ, schedules, drawings .

32
Q

What specification software have you used and why?

A

NBS Chorus, owned by RIBA. Cloud based specification software. Latest legislation and BS’s/includes workmanship clauses.

33
Q

What is a schedule of work ?

A

Without quantities, list the works require, quality mentioned with reference to the spec - JCT

34
Q

what is a specified schedule of works ?

A

Includes a description of the works

35
Q

What is the difference be a schedule of works and AS?

A

SoW = JCT can be paid as % per activity completed

AS = NEC each activity has to be 100 % complete for it paid

36
Q

What is a provisional quantity ?

A

Detailed by the new rules of measurement 2nd edition 2012 = a quantity that cannot be accurately determined (i.e. an estimate of the quantity)

37
Q

What is a Schedule of Rates and when shall they be used ?

A

List of rates per unit for works e.g. £1 pm2. Used when the nature of works is unknown and quantises can not be accurately determined or on frameworks.

37
Q

What is a Bill of Quantise?

A

Prepared by QS, Project specific measured quantises for work items from drawings and specs. Typically used on large projects or new builds .

38
Q

What can affect design?

A

Approved documents, technical constraints e.g. site size, BSs, CDM 2015, planning, Conservation areas, listed buildings, TPOs.

38
Q

What are some aspects the lead consultant should help the client with that fall outside design?

A

specific grants, public legislation, third party rights.

39
Q

What are third party rights

A

They provide for a duty of care to be extended by one of the contracting parties to a third party who is not party to the original contract. An example would be where an architect of a new office development owes a duty of care to an occupier of the development in so far as any subsequent defects which may arise.

  • alternative to collartal warrieties
  • The Contracts (Rights of Third Parties) Act 1999
  • need to be identified in the contract
40
Q

What are third party accreditations and what are their benefits?

A

They let customers know your product will reliably perform its job. BRE, UKAS, BBA

41
Q

What is the Considerate Constructors Scheme?

A

Organisation founded to raise standards in the construction industry for contractors, sites, suppliers and professionals. Care about appearance, community, environment, H&S

42
Q

Why as lead consultant is it important to communicate with the engineers?

A

Ensure compliance with the client brief, clear lines of communications though me, designs may conflict - Lux values. Collaboration even if there are no BIM requirements

43
Q

What is the difference between prov sums & prime costs ?

A

Prov - QS estimation of costs not designed in enough detail to directly price e.g. kitchen units types

prime cost - In general terms, the ‘prime cost’ is the sum of the direct cost of materials and labour associated with a production process. It is the direct cost of the inputs to a process that are necessary to create the output.- exclude profit and overheads -

44
Q

What are defined and undefined provisional costs?

A

Undefined = so little defined taht the contractor can not make an allowance for time for them - may be entitled to EoT e.g. ground conditions beneath existing unknown until demolition

Defined = defined in suffient etail the contractor is expected to allow time for tjem - e.g. fitted kitchen x.non of units, just not decided which exact units

45
Q

How do you plan project?

A

I use the RIBA Plan of works to determine the project requirements at each stage and to help put a fee proposal together

46
Q

Sustainability advice for materials?

A

low VOC materials

47
Q

When is stepped and ramped access required ?

A

BS8300 requires a change in level greater than 300 mm to have steps & ramp/less than 300 mm = just have a ramp.

some ambient people find steps easier than ramps. App Doc M requires - reasonable provisions for people to gain access and use buildings & facilities / more beneficial to have both.

48
Q

How did your designs comply with the relevant documentation for accessibility ?

A

Widths of corridors, accessible WC, widths of doors, accessible entrances.

49
Q

What are the required corridor widths?

A

Minimum- 1200mm - BS8300 would be used for obstructions

50
Q

How did you ensure durability for your designs?

A

consulted test certificates and product data sheets. Ensure client was happy with costs of durability. Getting samples to confirm tear resistant, look at thickness

51
Q

What were the specific details of the steps ?

A
52
Q

What was included within the designers risk register ?

A

Working at heights, excavations, asbestos, solvents, access to RWGs, Dust, Manual handling

53
Q

what documents did you use to help with your design ?

A
54
Q

What is the difference between the defined costs and the schedule of cost components?

A

Defined costs outline what the contractor can recover costs for - works on the project minus retention, and overheads ect.. r.

The SoCC is a ‘filing cabinet’ of defined costs. A document that outlines what a contractor will be paid for and how the calculation is made

55
Q

What cab defined costs be used for ?

A

Assessing CE’s

56
Q

What did the contractor price off ?

A

Outline designs, brief, est project value, client requirements

57
Q

In the NEC3 ECC Option E contract, what are direct & shared costs?

A

Direct - costs clearly for that specific project, e.g. labour, materials, plant, sub-con.
Shared - costs that might be spread across other projects, e.g. admin, owned plant.

58
Q

How did the contractor provide a quote for the works?

A

Fee % + prelims, completed on outline design.

59
Q

What was the fee % and what are typical fee %s?

A

3-10% dependant on project value.

60
