Q

What are the three Gateways?

A

he Building Safety Regulator need assurance and evidence that building safety issues have been properly considered at key stages of a project.

Gateway 1 focuses on obtaining planning permission by demonstrating the proposed design meets necessary safety requirements.

Gateway 2 involves rigorous inspections during construction to verify adherence to approved plans.

Gateway 3 ensures the building is fit for occupation

Q

What are the key differences between steel frame, concrete frame, and timber frame construction in terms of cost and programme?

A

Cost - steel frames are cost effective for medium spans, concrete is expensive, timber is cheapest for houses. Steel prices can be volatile.

Programme - Steel/timber can be fabricated of site and quick erection on site. Concrete is a lot slower.

Q

When does each frame system make most sense?

A

Steel - Offices, industrial buildings and long spans.

Concrete - Multi storey residential, car parks, hospitals - building needs high acoustic and thermal separation.

Timber - Housing, sites with limited budgets or for aesthetics

Q

How do different foundation types (strip, pad, raft, piled) influence cost and programme?

A

Strip - Generally most cost effective, and fast in ideal conditions.

Pad - cost is low to moderate and quick to install.

Raft - Higher costs due to large amount of concrete, often faster than deep foundations.

Piles - usually the most expensive and slower due to the complexity of install.

Q

What factors influence the selection of structural systems for industrial buildings compared to residential buildings?

A

Industrial focuses on functionality, large spans, fast construction, heavier loads.

Residential focuses on comfort and privacy, spans are smaller and sub dived, lighter loads, speed of construction not as important.

88
What is Concrete?
Cement + Aggregate + Water - C10 is low strength - C60 is high strength. Concrete is strong in compression but week in tension so its reinforced with steel bars to increase the tensile strength.
89
Post Tension v Pre tension concrete?
Pre tension is a method of increasing the tensile strength and is mainly carried out in the production of precast concrete (offsite) Post tension is a method of increasing the tensile strength and is mainly carried out on site with in-situ concrete (on site)
90
What is a foundation?
Function is to sustain the loads of a building in order to provide stability.
91
When would you use each type of foundation?
Strip - Low rise domestic building's, usually under load bearing walls. Pad - heavy concentrated loads, columns usually sit on top of a pad Raft - poor soils, used to spread load, where individual column loads are too heavy in poor soils. Piled - low bearing capacity of subsoil, requirement to transmit load to low level in ground. Large buildings, high rise buildings
92
Soil types
As clay expands and shrinks - deeper foundations are required such as piles to extend below soil movement zone.
93
Can you explain a takeoff for foundations?
* Remove topsoil * Excavate to reduced level * Disposal of material * Earthwork support * Formwork * Reinforcement * Concrete * Finish to concrete * Backfill and compact
94
What is radon and what is a radon barrier?
Radon is a radioactive gas produced by decay of uranium in soil, rock and water. Radon barrier is like a DPM, installed in foundations/slab to prevent harmful radon gas entering the building.
95
What are deleterious materials?
Deleterious materials are substances used on construction that pose health, safety and environmental risks. Examples are Asbestos, silica dust, lead
96
What is sick building syndrome?
Set of non-specific symptoms—such as headaches, fatigue, and eye, nose, or throat irritation—that occupants experience, which appear linked to time spent in a specific building. This could be caused by lighting, noise, mold, ventilation, etc
97
What defects would you find on a roof?
Ponding water (Flat roof) Sagging roofline Damaged, missing tiles Water leaks, condensation Damaged or corroded flashings
98
How would you connect two concrete slabs?
Dowelling with rebar - drill holes into existing slab, insert rebar and wire together before pouring new concrete. For large slaps or areas with high movement use fireboard filler to create expansion joint
99
What types of concrete slab finishes are the?
Trowel/Float finish - a smooth flat finish used for interior floors. Polished concrete - high gloss or matte finish achieve by grinding and polishing Exposed aggregate Epoxy coating - A durable, resinous coating often used in garages and industrial settings for protection.
100
What is a cold bridge?
A cold bridge, or thermal bridge, is a part of a building that conducts higher levels of heat than materials surrounding it. This will likely cause an insulation break-through or ‘weak spot’. In simple terms when warm structure meets a colder one.
101
What is a BRUKL Report?
Purpose: Ensures compliance with Part L of the Building Regulations regarding energy conservation, carbon emissions, and building fabric performance. Process: Conducted at both the "as designed" stage (pre-construction) and "as built" stage (post-construction). Requirements: A passing report is essential to secure an On-Construction Energy Performance Certificate (EPC).
