Design and spec Flashcards

1
Q

Tell me about your preperation of the design and specification of a building project from outline proposals to compeltion of the design and specficiation process.

A

I have recently been involved with the specification design and delivery of a cyclical redeocration project. The outline proposal was developed from a detail condition survey of the scheme, which reommendations were then included within a report. A significant item was to replace the timber walkway balustrades. However, due to budget constraints and leaseholder S20, the client requested their repair rather than replacement. I completed a detailed survey of all balustrades and quantified the different repairs required. I then specified the type of materials, treated softwood, fixings and decoration requirments.

Q

Talk me through your experience of the specification process, including detailed knowledge of the main methods of specification.

A

I have been involved with different projects through the entire design and specification process. The process can be intitated at RIBA Stages 0 and continues at 5. For example, in my case study intital design requirements were determined at the strip out stage where a descrptive specifcation of elements meeting building regulations were discussed. For example the requirement of fire compartmentation to the hall and acoustic requirements to the party wall. I would then develop a performance specification that could be issued to the contractor outlining exact materials, methods and standards to be completed. During the project I was completed a prescriptive specifiction of the fire curtain for the contractor to implement that would meet the requirements of buildng regulations part B.

Q

How have you dealt with the design and specifiction process, and its relevance and importance to the procurement and execution of the contract selected for the building works?

A

I have been involved with projects that have been procured through different contracts. I have developed specifications for fire door sets that are descriptive so that the works can procured through a JCT MW with contractors design to allow for the specialsied contractor to procure materails that met performance requirements.

Q

How have you managed the design process to incorporate design works by other in the specification?

A

With reference to Hillcrest, the project involved elements of asbestos removal and replacement of meters and electrical services. At my appointment, I informed the client that specialist consultants should be appointed to design the areas around these elements. I appointed an M&E and Asbestos consultant from our internal approved consultant list. I communicated with them and met them onsite to ensure that the objectives/brief was understood. A plan of work and M&E spec was developed that I included within my overall specification.

Q

Hillcrest Fire Remedial WorksHow did you deal with the ventilation and what guidance a part from the building regulations did you follow?

A

To address the ventilation within the riser we introduced an intumescent grill at the top of the riser and at the bottom of the riser. We then allowed for the floor slab to core drilled to allow for natural ventilation. I referred to BS 6891 table 6 which outlined a requirement for the grills to be 0.05m2.

Q

Hillcrest Fire Remedial WorksDid you check the duct where the pipework went into individual flats or other areas?

A

The view of the gas services were obstructed by the asbestos insulation board within the cupboard. As I was unable to prescribe firestopping works to be priced exactly, I included a schedule of rates within the specification for a range of firestopping works for the contractor to price. I also included within the specification an item for the CA to inspect all areas once asbestos had been removed and new services had been installed.

Q

What is the difference between a performance and a prescription specification?

A

Performance specifcation - also known as openPrescriptive specification - also known as closedPerformance provides more freedom to contractor to achieve the desired end goal, therefore potentailly finding best value for money. Typically used on straight forward projects.Prescriptive specification sets out exactly what will be expected from the contractor at the end of the project. This enables the client to be sure of what they will get for their investement. Often used in projects where specialist systems are requried.

54
Q

Explain the key difference between Prescriptive and Performance specifications.

A

Performance Specifications address the operational requirements of an installation. The focus is on the project outcome, indicating how the final project must be able to function. Prescriptive Specifications contain detailed descriptions of what specific materials must be used as well as the installation instructions.

55

80
Q

Hillcrest Fire RemedialsWhat advice did you give your client regarding the procurement route?

A

I advised the client that due to the nature of the works being high risk, we should maintain as much design control as possible. I therefore recommended that we procure the contract traditionally.

81
Q

HIllcrest Fire RemedialsWhat did you understand about the design of works requried when you attended site?

A

The FRA identified that the riser door sets needed to be repalced with FD30 units. From attending sites I understood that the asbestos board was fit into the door frame and would need to be removed in order for the door sets to be replaced. Furthermore, I identified that the electrical meters were fixed directly to the amosite and to allow for the board to be removed there could be a requirement for the meters to also be replaced.

82
Q

Hillcrest Fire RemedialsWhat did you comunicate with and manage the specialist to produce?

A

I appointed specialist M&E and asbestos subconsltants from our approved subconsultant list.I communicated the objectives of the project and outlined the works. With the M&E specialist I advised them that we would need to produce a specifiaction for the replacement of the meters, all replacement services and it should also include provision for deailing with statutory undertakers.For the asbestos specialist, I explained that we would need a plan of work for removing to determine how the asbestos would be removed safely without contaminating the rest of the property.

83
Q

Hillcrest Fire RemedialsWhat were the challenges that you faced specifying this project?

A

The main challenge was in realtion to removing the meters and asbestos.In order to remove/replace the meters power would need to be shut off, the asbestos would then need to be removed in order to install the new meters. The asbestos management would require a pressurised unit to be set up in the hallway to prevent contaminination, which would prevent escape of the residents. The only way that the works could be acheived safely was to decant the residents.

Q

What are the pros and cons of a pitched roof?

A

Providing the roof is constructed correctly and the tiles laid correctly, the life of the tiles should last a minimum of 50-60 years providing it is maintained. Pitched roofs can be constructed from pre-fabricated trusses which reduce the time required for construction and do not require an as skilled precise workforce. The pitched roof would allow for storage space for the landlord or tenants.The negatives were that it required scaffolding to be raised higher which increases the cost, the roof would be harder to maintain as it would require a cherry picker or mobile access tower to do safely, the load of the roof can cause roof spread if not adequately restrained.

101
Q

What are the pros and cons of a flat roof?

A

They can be laid down relatively quickly and made weatherproof depending on the material finish chosen. They are easier to maintain and access. If done correctly, the roof finish can last well over 20 years and can come with a guarantee. They are relatively easy to install and safer to do so. The negatives are that although maintenance is easier, it will require it more often particularly with clearing the rain water outlets to prevent blockages and water leakages. If there is a leak, it can be difficult to pinpoint. They are susceptible to heat damage.

102
Q

What did you do to be compliant with equality act?

A

The equality act builds on Part M. It requires employers to make reasonable adjustments to not discriminate against minorities or those with disabilities and regard must be given to any specific needs of likely building users. I informed my client that in order to comply with Part M, we would need to make adjustments to the extension but in order to allow her son to be fully independent in the future, other alterations could be made such as strengthening the ceiling to allow for hoists, widening all the ground floor doors, creating a ramp up to the front door. These changes were not unreasonable given the circumstances. The equality act although not applicable to private residences justified the need to widen all the doors and create level access throughout the house including making the staircase slightly more narrow to allow for wheelchair access through the hallway.

103
Q

What would you look at for disabled access?

A
  • Who is using the building? * What are their needs? * Is there enough width to get a wheelchair through, are there any steps that need to be avoided, how do we deal with fire safety? * Will there be any changes to their needs in the future?
104
Q

What is a provisional sum ?

A

A provisional sum relates to works that cannot be designed / specified at the outset.

105
Q

What is a defined provisional sum ?

A

Defined provisional sums are those where specific works have not been fully designed, however, there is enough information available for the contractor to make a proper allowance in their price and programmed.

106
Q

What is a undefined provisional sum ?

A

Undefined provisional sums are not accounted for in the contractor’s price and programmed. This means that the client is taking the risk for the works and the contractor may be entitled to an extension of time and additional payments.

107
Q

What is approved doc M ?

A

111
Q

What is a bill of quantities ?

A

Document prepared by the QS/cost consultant and provides project specific measured quantities of items of work identified in specifications and drawings. Advantage is that all contractors pricing same quantities which allow for a fair and accurate tender evaluation - this assists with any variations, interim payments and schedule of rates. Usually used on larger projects.

112
Q

  • Preliminaries * Preamble,* Specification* Materials* Workmanship* SOW* Drawings* Photos
113
Q

What is a Preamble?

A

A preamble is an explanation of a document, commonly found in contracts, specifications and bills of quantities. It can help with the interpretation of the document. A preamble might include:• A description of the parties to the contract.• A description of the competence (or lack of it) of the parties to the contract. This can be taken to set a general standard for the quality of goods or services expected, or the level of support required.• The background to the document.• A summary of the negotiations.• Tendering procedures.• The objectives of the project.• Other related documents or previous contracts and their relationship to the current document.• It should only include important information and should avoid including or repeating rights or obligations which should be set out in the main body of the document.

124
Q

Explain the key difference between Prescriptive and Performance specifications.

A

Performance Specifications address the operational requirements of an installation. The focus is on the project outcome, indicating how the final project must be able to function. Prescriptive Specifications contain detailed descriptions of what specific materials must be used as well as the installation instructions.

125
Q

Explain the advantages of a prescriptive specification.

A

Prescriptive specifications give the client much more certainty about the end product when making investment decisions (such as when they appoint the contractor), and place a greater burden on the designer to ensure proper installation rather than the contractor.

126
Q

Why might you recommend the use of a performance specification?

A

The performance of the works are specified, the contractor reserves the option of design. Performance specification gives the contractor and suppliers more scope to innovate and adopt cost effective methods of work, potentially offering better value for money.

127
Q

What kinds of specification software are you aware of?
