Knowing
Explain your understanding of Modern Methods of Construction (MMC)
Is a collective term for building methods that are designed to be more efficient and effective than the traditional ‘brick and block’ method of constructing buildings, including residential buildings such as houses and blocks of flat.
Give examples of MMC
- off-site construction - such as roof floors or walls.
- volumetric and panellised construction - such as complete panelled sections such as the roof made off site or whole parts including walls which are joined together on site
- timber frame and precast concrete construction.
What are the different stages of the RIBA Plan of Work 2020? And what is your role during the different stages?
7 STAGES
Stage 0 - Strategic Definition - Clients requirements
Stage 1 - Preparation and briefing - Feasibility studies project budget.
Stage 2 - Concept Design - Cost Plan end of this stage
Stage 3 - Spatial coordination - Cost plan
Stage 4 - Technical design - pretender cost plan
Stage 5 - Manufacturing and Construction - Contract phase responsibilities
Stage 6 - Handover - Final certificate
Stage 7 - In use to end of life - H&S file
What is your understanding of Building Regulations, Codes and other related legislation?
Building Regulations set standards for the design and construction of buildings to ensure the safety and health for people, including those with disabilities in or about those buildings and to help conserve fuel and power.
What are some of the changes made to Buildings Regulations for Higher Risk Buildings?
What is a higher risk building?
Who are the building safety regulators?
What are the different gateways?
who are the duty holders ?
Higher risk building is over 18m high, 7 storey or more, hospital or care home or schools - looks into the usage and escape route (only 1). Contains 2 residential units.
Gateway legislation forces people to develop complaint design for approval prior to construction commencing. Built in accordance with approved design. Accurate record of what is built.
Hard stop milestones to prevent work progressing until regulator is satisfied.
Gateway 3 - client can’t occupy until regulator has signed off.
BSR are appointed by HSE health and safety executive as a regulatory body to build to a standard which is the building safety act.
1 submission at planning stage
2 stage 3 & 4 design submission - works cannot commence until approval of gateway two
3 completion certificate application
Duty holders are client, principle designer, principle contractor, designers and contractors

What is a HBN and what’s its purpose?
Health Building Note - documents used in the health care sector which detail the minimum standards required for the design and construction of health care buildings.
What is a HTM and what is its purpose?
Health technical memorandum - documents used in the health care sector which details good practice requirements
What is strip foundations?
Shallow continuous excavation to support the perimeter and internal walls. Suitable for most subsoils and light structural design.
What are pad foundations?
Provide a base for reinforced concrete or steel columns, formed by making isolated excavation in shape of square or rectangle. Include reinforcement mesh and spread load to rock below.
What are the technical advantages and disadvantages of steel frames ?
Lightweight construction
Consistent
100% recyclable and inorganic - will not warp crack split crack or creep
highest strength to weight ratio
Do not expand or contract with temperature changes
Lighter than concrete frames - cheaper foundations.
Quick erection
Fluctuating costs - no cost certainty
Not as fire resistant or sound resistant
Requires fire protection to be retrospectively installed.
What are the technical advantages and disadvantages of concrete frames?
Subject to weather conditions
Labour intensive, more time consuming to install
Heavier require larger foundations
Slower construction
Sound resistant
Fire protection
Good sound an heat protection
What are retaining walls?
An earth retaining structure for whole or part of their heights. Support and retain soils laterally so they can be retained at different levels on the two sides.
Describe a cold flat roof construction
The void or slab below is insulated from heat loss from below and is therefore at a colder temperature than the room below during cold weather.
Roof covering
ply deck
void
insulation and roof joists
ceiling level
Describe a warm flat roof construction
Insluation placed on top of the roof deck. Ceiling or roof void is similar temperature as roof.
