Design And Spec Flashcards
What are preambles?
certain specification for how the job is to be done.
Explanation of document/process
an explanation of a document, commonly found in contracts, specficiations 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, the background of the document, the objectives of the project etc.
What is a performance Spec?
An open spec with brief requirements
What is an output spec?
List of client requirements, can be a design and build
What is novation?
Where the contractor takes an architect from the client and appoints them.
What is a collateral Warranty?
Gives recourse for parties not involved in the main contract but may be affected. i.e a third party.
What is a latent defect?
A fault that couldn’t have been discovered with a thorough survey at the time
What is an Extension of Time?
Allowance in the contract for a contract completion date to be adjusted if there was a delay that was not the contractors fault.
What is a Relevant Event?
An event that causes a delay to the completion date, which is either caused by the client or is a neutral event not caused by either party.
Name some examples of a Relevant Event?
Variations
Exceptionally Adverse Weather
Civil Commotion or terrorism
Failure to provide information
Delay on the part of a nominated sub-contractor
Statutory undertakers work
Delay in giving contractor possession of the site
Force Majeure
Loss of specified peril, such as flood.
The supple of materials and goods by the client.
National Strikes
Changes in statutory requirements.
Delays in receiving permissions that the contractor has reasonable steps to avoid.
What is a provisional sum?
An allowance for a specific element of works that is not yet defined in enough detail for tenderer s to accurately price.
Which RIBA stages are pre-contract?
0-4
When do post contract stages start?
After the contract has been signed not at PC.
What are the RIBA stages of Work?
0 - Strategic Definition 1 - Preparation and Brief 2 - Concept Design 3 - Developed Design 4 - Technical Design 5 - Manufacturing and Construction 6 - Handover and Completion 7 - Use
Tell me about H&S regs and how they impact on design?
refer to CDM & Surveying safely guidance
What does intuitive mean?
User friendly
What is a designers risk assessment and how do you do it?
used to manage risks during the build phrase
Identify risk and put things in place to manage/reduce
Measured by likelihood/impact
Why are reputable manufacturers & contractors useful when designing
Early Involvement - guarantees and warranties
Buildability
Better understanding of risk management
Aware of conflics of interest
Can you name any manufacturers/products you use?
IKO, Bauder, Sika etc
When have you given advise on sustainability issues on a project?
SIP on Caistor BREEAM EPC Any others? Part L
What is the definition of embodied energy?
How much energy is used to make a product
What is a specification and how do you product one?
Pre-sambles, prelims and shcedule of works
PCIP
Drawings
It’s something the contractors work to to build something
What does NBS Stand for?
National Building Specification
What trade associations can help with design and spec?
TRADA NHBC LEAD SHEET ASSOCIATION Blue Book Mastic Asphalt Council Concrete Society Concrete Repair Association Concrete Block Association IEE (Electrical) FENSA BREEAM NIC/EIC Metal cladding and roofing association
Whats the difference between a prescriptive and performance specification?
Performance spec is a set of standards where the contractor then recommends a product/does the prescriptive spec
Prescriptive spec is what we do. Detailed specification with products.
What is the current edition of the Design and Specification GN?
1st Edition
2013
What does the design and spec GN cover?
− Roles of the lead consultant − Management − Common Considerations (compliance, sustainability, safety) − Design Process Management (documents, NBS, standardisation) − Design Process (RIBA stages) − Detailed Design − Specification preparation − Legislative compliance − Construction stage − Commissioning / occupation
What are the RIBA stages of Work?
0 - Strategic Definition 1 - Preparation and Briefing 2 - Concept Design 3 - Spatial Coordination 4 - Technical Design 5 - Manufacturing and Construction 6 - Handover 7 - Use
What changes to the RIBA stages of work were implemented in 2020?
Addition of sustainability project strategy
Improved guidance relating to the planning process, procurement and information requirements at each stage.
- addition of detailed stage descriptions.
What are Preliminaries?
◼ Provides a description of the project that allows a contractor to assess costs which,
whilst they do not form part of any package of works, are required by the method and
circumstances of the works
◼ Purpose is to describe the works as a whole and to specify general conditions and
requirements for their execution.
◼ They include the following;
− The site (description, access, parking)
− The works
− Contract conditions (rectification, payments, insurance, collateral warranties)
− Management of the works (working hours, etc)
− Security, health and safety
− Site setup and welfare
What are Specifications?
◼ Describes the material and workmanship required for the project
◼ They do not include cost, quantities or drawn information, so need to
be read alongside other information such as;
− Bill of Quantities
− Schedules
− Drawings
◼ Specifications vary dependant on the project;
− Performance Specifications: Gives suppliers more scope to innovate and
adapt cost effective solutions
− Prescriptive Specification: Full design, client certainty on end product
− Proprietary Specification: Single type of product
What is NBS?
◼ National Building Specification (NBS)
− Owned by RIBA
− Latest edition is NBS Chorus (Cloud based)
− Describes materials, standards and workmanship for construction projects
− Also contains preliminaries documents
− UK industry Standard
− It is used as it provides all the latest legislation and British standards
relevant to the works
What are Preambles?
◼ Explanation of a document to help with interpretation ◼ Do not form part of the cost ◼ Might include; − Description of parties to the contract − Description of competence − Background − Summary of negotiations − Tendering Procedure − Objectives
What is a schedule of work?
◼ Are without quantities instructional lists. Simply lists the work required
◼ Should allow the contractor to identify significant work and materials that will be
required
◼ Where a schedule includes a description of the work required, this is a ‘specified’
schedule of work.
◼ Quality should be provided by reference to the specification
◼ Location and size should be provided on drawings
Name some statutory regulations influencing design?
− British Standards (BS )000() (Codes of Practice)
+ BS 8012: Protection of below ground structures against
water from the ground
+ BS 9999: Fire safety in the design, management and use of
buildings
− ISO (international Organization for Standardisation)
− Building Regulations
− British Board of Agrement (certification scheme to confirm
products comply with British standards)
− BRE (BRE Digest and BREEAM)
− CDM 2015
− Health & Safety
− Planning / Listed Buildings / Conservation
What is BIM?
Building Information Management
◼ Describes the process of creating and managing digital information about a
built asset
◼ BIM Levels;
− Level 0: Unmanaged CAD
− Level 1: Managed CAD in 2D or 3D
− Level 2: Managed 3D environment with data attached but created
in separate discipline models
− Level 3: Single online project model with construction
sequencing, cost and life cycle management information
