Q

Building Safety Act 2022 recent updates

A
  • amendments to the Building Regulations, which will apply to all
    applications for building control consent from 1 October 2023.
  • Government has formed a new regulatory body within the Health and Safety Executive
    (HSE) called the Building Safety Regulator (BSR).
  • Approved Inspectors will need to become Registered Building Control Approvers (RBCA) which
    requires registration with the BSR.
    *Building control is to become a regulated profession, meaning that the job title ‘Building Inspector’ will
    be protected in law. They must have certain qualifications or experience and register with the BSR.
  • All RBIs will have their competence third party validated against the Building Inspector Competency
    Framework for the class of registration they are applying for.

Q
  1. Advantages timber frame?
A
  • Speed of installation:
  • A prefabricated timber frame can be erected on site faster than a comparable brick and block construction. This enables interior trades such as plastering and electrical wiring to begin work earlier in the build programme, as the interior will be exposed to weather for less time
  • Good delivery of an airtight envelope
  • Little waste
  • No additional finishes required
  • Quality:
  • Off site fabrication can allow higher quality to be achieved than in the less controlled conditions of a construction site.
  • Thermal performance:
  • Timber frame structures can typically achieve a better thermal performance than masonry structures. Their low thermal mass allows spaces enclosed by timber frames to heat up more quickly than masonry construction, however they will also tend to cool more quickly.
  • Sustainable as long as the balance of replacing trees used is maintained
  • Requires less CO2 to process and produce than steel

Q
  1. Disadvantages of CLT?
A
  • Can be costly
  • Requires accurately set out groundworks
  • Requires completed designs ahead of start on site, to allow for offsite manufacture
  • Requires external cladding or render to provide weatherproof envelope
  • Use limited to above damp-proof course or equivalent level
  • Considerable design coordination before work starts on site, as all openings for windows, doors and services should be factory-formed. Cutting on site is possible, although not desirable, due to lower-quality finished edges and a possible subsequent need for structural checks

Q
  1. Advantages of CLT frame?
A
  • Simple and fast onsite construction process
  • Suitable for non-visible as well as exposed finishes
  • Vapour-permeable wall construction
  • Robust finished wall will take sundry fixings
  • Need for robust upfront design may improve overall design and efficiency
  • Light weight reduces load on foundations so less need for materials with high embodied energy (eg concrete)
  • Greater load distribution can reduce thickness of transfer slabs
  • Good delivery of airtight envelope
  • Environmental / sustainability: Provided the timber is sustainably sourced, there are environmental advantages in the use of CLT. The embodied carbon of timber products is low relative to many other construction materials. As with all plant- based materials, carbon is stored during tree growth and continues to be stored through its use as a building material. At the end of its life, carbon is released
  • Construction on site doesn’t last more than a few days. It is a quick and dry process, with very little waste generation.
  • Greater quality control: Generally, panels made of CLT are assembled and cut in their production, already foreseeing the joints, openings, and drills specified in the design
  • Broadly dimensionally stable and shrinks less than standard solid timber construction.
  • Either through natural decomposition, returning other nutrients to the soil, or through the generation of heat/ energy by burning it as a fuel, either way providing a comparatively highly efficient end-of-life treatment.
  • Imperfections in the original timber, such as knots, can be removed in the factory to reduce variability and enhance structural performance. CLT differs from glulam in that it is formed into panels rather than beams, hence the layers of timber (lamellas) are bonded perpendicularly to one another, resulting in structural strength across two dimensions, and improving structural integrity and dimensional stability
  • It’s a sustainable material because it’s composed of wood, a renewable resource (usually from reforestation), and doesn’t require the burning of fossil fuels during its production.
  • Since it is a solid panel composed of a single material, the structure requires no cladding, which reduces the need for labour and materials for its final appearance.

Q
  1. How PV panels work
A

Solar photovoltaic (also known as solar PV) systems convert energy from the sun into electricity. Solar panels are made of a thin layer of semi-conducting material sandwiched between a sheet of glass and a polymer resin. When exposed to daylight, the semi-conducting material becomes ‘energised’ and this produces electricity.

The electricity goes through a inductor, converting it from Direct current to alternating current to make it usable electricity within the home, or it can be sold back to the national grid.

Q
  1. What is CLT?
A

Cross Laminated Timber - a type of engineered wood product that is used as a sustainable and renewable building material

CLT is formed of kiln-dried spruce or pine boards which are stacked in layers on top of each other at 90° (three, five, seven or nine layers depending on structural requirements), coated with a layer of polyurethane adhesive and subjected to immense hydraulic pressure to create large, stiff, dimensionally stable panels.
These timber panels, which can measure up to 3.5m in width and 20m in length, depending on specification, can be used to create the complete superstructure of a building. CLT panels are precision cut by CNC machines (from 3D CAD drawings) and delivered to site to be installed

Q
  1. Tell me everything you know about Asbestos?
A
  • Asbestos is the term used for the fibrous forms of several naturally occurring minerals, which are found throughout the world.
  • Asbestos is considered a deleterious material
  • Asbestos materials in good condition are safe unless fibres become airborne, which happens when materials are damaged
  • 1960s 1980s and it was extensively used when building post-war New Towns.
  • The Health and Safety at Work Act was introduced in 1974 and this enabled the government to bring in subsequent legislation aimed specifically at asbestos, as the harmful effects on the body became better known.
  • 1999 all forms of asbestos were banned
    The Management of Health and Safety at Work Regulations 1999 - employers must carry out risk assessments to eliminate or reduce risks. In the context of our projects it would be a risk assessment, request for the asbestos register, and depending on the nature of work an R&D survey.
  • The Control of Asbestos Regulations 2012 impose regulations around managing and handling asbestos and implementation of asbestos management plans.

Q
  1. What types of roof insulation are there?
A
  • warm vs cold
  • Warm – A warm roof is where the insulation is attached to the floor decking and rafters. The entire roof is insulated which leads to a better performance, hence the name ‘Warm Roof’. Ceiling height to be considered, but more common with pitched roofs which feature a higher profile where this is less of an issue.
  • Cold – Insulation is placed below the roof rafters, less expensive but can result in heat loss and requires ventilation to avoid condensation

Q
  1. What types of piling are you aware of?
A
  • Bored - Bored piles remove spoil to form a hole for the pile which is poured in situ.
  • Sheet piling - Sheet piles are sections of sheet materials with interlocking edges that are driven into the ground to provide earth retention and excavation support
  • Secant piles – interlocking piles (male and female, often different diameters and hardness) are bored to provide a combination of foundations and basement walls. They go someway in providing a waterproof structure. Secant piles are often seen when a top down construction method is used.
  • Pre-cast piles – pre-cast piles are brought to site and hammered into the ground. Not often favoured due to the high noise levels associated with installation and the lack of flexibility in terms of depth required

  1. Party Wall Act 1996
A

Party Wall Act 1996
The Party Wall Act gives the owner of a property the legal right to undertake certain works that may otherwise be construed as trespass or nuisance. You must tell your neighbours if you want to carry out any building work near or on your shared property boundary, or ‘party wall’, in England and Wales. Party walls stand on the land of 2 or more owners and either:
* form part of a building
* don’t form part of a building, such as a garden wall (not wooden fences)
Walls on one owner’s land used by other owners (2 or more) to separate their buildings are also party walls. You must tell your neighbour if you want to:
* build on or at the boundary of your 2 properties
* work on an existing party wall or party structure
* dig below and near to the foundation level of their property

Q
  1. Ground source heat pump
A
  • A ground source heat pump system harnesses natural heat from underground.
  • Fluid is pressurised and passed through a system of open or closed loop pipes and absorbs the naturally occurring heat stored in the ground, the fluid is compressed and goes through a heat exchanger, which extracts the heat and transfers it to the heat pump. The heat is then transferred to the heating system
  • Advantages: sustainable technology, more economical than traditional heating methods, cuts costs
  • Limitations: Expensive installation, disruptive to install retrospectively, bulky & loud

  • Implementation is a requirement in non domestic buildings.
  • Must be regularly tested and maintained.
  • Required to operate fully automatically and give illumination of a sufficiently high level to enable all occupants to evacuate the premises safely.
  • To be provided in line with Local Authority requirements and Building Regulations, British Standards provides guidelines to work to
    o Emergency escape lighting – To illuminate the escape route.
    o Standby lighting– that part of an emergency lighting system provided to enable normal activities to continue substantially unchanged.
    o Escape route lighting – identifies the escape route and keeps it sufficiently lit.
    o Open area lighting – ensures that there is sufficient illumination to allow the occupants of a building to reach a place where an escape route can be identified.
63
Q
  1. Fire prevention – Detectors, active & passive protection

Fire doors with automatic closers, intumescent paint, smoke seals, fire stopping around vents, fire access lift, wet risers, dry risers.

64
Q
  1. Can you explain to me a ventilation system used on one of your projects?
A

Mechanical ventilation heat recovery (MVHR) will be provided, which allows the recovery of a significant amount of thermal energy which is fundamental to ensuring a low space heating energy demand.

All air handling units will include heat recovery and supply air will be tempered by an electric heating coil. Air will be distributed via galvanised steel ductwork and distributed by ceiling mounted diffusers.

Attenuators will be provided on duct branches to minimise noise breakout from rehearsal/practice spaces and prevent crosstalk between rooms. This is in line with the recommendation with the acoustic report.

Natural ventilation via window openings is recommended for the office spaces and the foyer, to create cross ventilation within the building and allow purge ventilation for mitigation of overheating

65
Q
  1. Explain the Heating and cooling strategy on one of your projects
A

Operational temperature is critical to prolong the life expectancy and operational output in the rehearsal spaces and storage areas, refrigerant based Variable Refrigerant Volume (VRV) systems were designed within these spaces to provide heating and cooling via wall mounted units. Consideration was also given to strict noise criteria that must be met in applying this choice of ventilation.
For the areas where there is no upper limit operational temperature, Air Source Heat Pumps (ASHPs) will provide low temperature hot water (LTHW) for heating.

Q

Value management vs value engineering?

A

The output from a VM study is a report outlining different approaches to the relationship between project objectives and business needs, or to strategic, projectrelated problems such as which site to select for a new development or which procurement route to use. The output from a VE study on the other hand is a summary of different approaches to achieving the required functionality for a particular material, component or system, the comparative costs of each of the approaches assessed, and a recommended approach that provides the best value for the project

87
Q

What is value management?

A

value management is a process to explore how value could be provided for a project at a strategic level by helping to develop the right project brief. Used effectively, it can reduce design and construction time by giving the team a clearer focus on the client’s priority requirements.

88
Q

What foundations were opted for at SJM for the CLT frame?

A

Heave requirements need to be considered and so foundation depths need be provided the risk of heave.
A foundation raft has been shown as we believe that that will be the most efficient foundation solution when considered holistically.
Advantages of this foundation solution are:
* Avoids the use of precast and avoids the implications on cost and programme that we are seeing other projects experience at this current time. This will also help to ease site logistics.
* No large precast sections to be craned and the concrete volume can be minimised including the depths of excavations. The ground below the raft slab needs engineering generally to only half the depth than a traditional pad and strip foundation system.
* Once the concrete is poured the foundation is completed and provides a flat and level surface for the contractor to work from when erecting the superstructure.
* Avoids introduction of additional precast trade and additional wet trades as no ‘sleeper’ walls required to provide bearings to the precast elements.

89
Q

What is the difference between British standards and Building regulations?

A
  • Building regulations are law and must be complied with
  • British standards are optional but is good practice to adhere to and implement

93
Q

Tell me of a time you have checked a design for compliance?

A

When developing the RIBA 2/3 design and considering the office layout and having it as a passage to the music library, in a DTM I suggested surrounding the layout we were proposing to make it more aligned with project brief my understanding from the bands of the function and desired flow of the building.

94
Q

Tell me of a time you have suggested an alternate method of construction?

A

Whilst suggesting alternate design methods is not within my remit of specialism as a PM, I have on the SJM site facilitated the process and meetings for suggesting use of CLT to DIO to ensure it was approved from the client, and due to being a new material obtaining approval from a CTM perspective.

98
Q
  1. differences Pre-fabricated foundations vs in-situ?
A
  • Quality - The factory-controlled environment allows for greater quality control during the manufacturing process.
  • Programme – Since the foundation elements are manufactured off-site, construction time on-site can be significantly reduced. The prefabricated elements can be quickly installed, saving time and improving project efficiency. However, there are limitations on programme efficiencies If there are long lead in times or missed factory slots.
  • Cost – minimal difference. Prefabricated foundations can be cost-effective due to reduced labor and on-site construction time. The off-site manufacturing process allows for better cost control and planning, but can sometimes only have minimal cost differences.
  • Reduced Site Disruption - Prefabricated foundations require less on-site construction activities, resulting in reduced noise, dust, and disruption to the surrounding area.
  • Customisation - In situ foundations can be customized to suit specific project requirements. The flexibility in design allows for the creation of complex foundation shapes and sizes which can be amended during construction.
99
Q
  1. Why the RIBA 2020 PoW was updated?

Q
  1. Building Safety Act
A

Building Safety Act 2022 (BSA) represents the most significant regulatory reform to the UK’s built environment industry since the Building Act 1984. The Building Safety Act 2022 was created to address safety issues brought to light by the Grenfell disaster. The Act places duties on landlords of residential buildings considered higher-risk to remediate building defects and ensure safety standards are met. The Act creates three new bodies to provide oversight: the Building Safety Regulator, the National Regulator of Construction Products, and the New Homes Ombudsman. Many of the detailed provisions in the Act will be implemented over the next two years through a programme of secondary legislation.

101
Q
  1. Building Safety Act and does it affect my project?

103
Q
  1. How does construction of a pre-fabricated building differ to a more traditional build?
A
  • Assembly Process: Pre-fabricated buildings are constructed off-site in a factory or manufacturing facility, whereas traditional buildings are built on-site.
  • Speed of Construction: Pre-fabricated buildings generally have shorter construction timelines compared to traditional builds. Since the building components are manufactured in advance, on-site assembly can be completed relatively quickly.
  • Precision and Quality Control: Pre-fabricated building components are manufactured using precise measurements and quality control processes in a controlled factory environment. This can result in greater accuracy, consistency, and quality compared to on-site construction, where human errors or environmental factors may have a greater impact.
  • Flexibility and Customization: While pre-fabricated buildings often offer a range of standard designs and configurations, customization options may be limited compared to traditional construction.
  • Transportation and Logistics: Pre-fabricated building components need to be transported from the factory to the construction site. This requires careful planning and coordination.
  • Site Requirements and Foundations: Pre-fabricated buildings may have specific requirements for the foundation or site preparation. The foundation needs to be properly designed and prepared to accommodate the load and installation of the pre-fabricated components. In traditional construction, the foundation can be tailored to the specific needs of the building during the on-site construction process.

There are three other types of asbestos fibre which have had limited use and are found occasionally in various products. These are actinolite, anthophyllite and tremolite.
Colour should never be used to identify asbestos, as it’s usually mixed with other materials.

Q

where is asbestos typically found

A

*sprayed coatings
*pipe insulation
*Asbestos Insulating Board (AIB) used for ceiling, door and window panels
*floor tiles
*asbestos cement products
*textured coatings (such as Artex).

125
Q

A brief history of asbestos.

A

As early as 4000 BC there was evidence of the use of asbestos as lamp wicks. The name asbestos is derived from the Greek meaning indestructible or inextinguishable.
Over 6 million tonnes of asbestos (mainly chrysotile) have been imported into the UK since 1900. It was used in a wide variety of industries and many different types of properties including schools, hospitals, offices, and factories.
The peak period was the 1960s 1980s and it was extensively used when building post-war New Towns.

The Health and Safety at Work Act was introduced in 1974 and this enabled the government to bring in subsequent legislation aimed specifically at asbestos, as the harmful effects on the body became better known.
Crocidolite and amosite asbestos were banned in 1985, with the use of chrysotile allowed to continue as it was seen as less harmful.
Chrysotile asbestos was finally banned in 1999.

Q

Health issues associated with asbestos

A

Mesothelioma
* This is a cancer which affects the mesothelium, the protective lining that covers many of the internal organs of the body.
* It typically takes 30 to 40 years to develop.
* Is almost always fatal and is particularly linked to crocidolite and amosite asbestos.
* It can develop after a relatively low exposure

Asbestos-related lung cancer
* Asbestos-related lung cancer is the same as lung cancer caused by smoking and other diseases.
* The combination of smoking and asbestos exposure is especially harmful. The disease can take 10 to 30 years to develop from a first exposure.

Asbestosis
* This is a serious scarring of the lung that normally occurs after heavy exposure over many years.
* The disease can take 15 to 60 years to develop. In severe cases it can be fatal.

Pleural diseases
* The lining of the lung (pleura) thickens and swells causing shortness of breath and discomfort in the chest.
* Caused after heavy exposure.

127
Q

Regulation associated with asbestos

A

o The Health and Safety at Work etc Act 1974

o The Management of Health and Safety at Work Regulations 1999

o The Control of Asbestos Regulations 2012

128
Q

The Management of Health and Safety at Work Regulations 1999

A

The main requirement of the Management of Health and Safety at Work Regulations is that employers must carry out risk assessments to eliminate or reduce risks.

129
Q

The Control of Asbestos Regulations 2012

A

These regulations deal specifically with asbestos and the main requirements are as follows.
*Employees responsible for building maintenance have a duty to manage the asbestos in them.
*If existing asbestos-containing materials are in good condition and are not likely to be damaged, they may be left in place, and their condition monitored to ensure they are not disturbed.
*If you want to do any building or maintenance work in buildings that might contain asbestos you need to identify where it is and its type and condition. Assess the risks, and manage and control these risks.
*In the majority of cases work with asbestos needs to be done by a licensed contractor.
*The control limit for asbestos is 0.1 asbestos fibres per cubic centimeter of air (0.1 f/cm3). Work activities involving asbestos must be reduced to as far below the control limit as possible.

130
Q

Duty to manage asbestos

A

The duty to manage asbestos is contained within Regulation 4 of the Control of Asbestos Regulations 2012. It requires the person responsible (the dutyholder) to:
*take reasonable steps to find out if there are any asbestos-containing materials (ACMs) in a premises, and if so, where it is and the condition it is in
*make, and keep up to date, a record of the location and condition of the asbestos-containing materials
*prepare a plan of how these materials will be managed
*periodically review the plan and ensure it is kept up to date
*provide information on the location and condition of the materials to anyone who is liable to work on them or disturb them.

131
Q

types of asbestos surveys

A

There are two types of survey for ACM:
*asbestos management surveys
*refurbishment/demolition surveys.

132
Q

The asbestos risk register

A

The asbestos risk register is key to managing any asbestos items found, or presumed to be, in your buildings.

The risk register needs to be updated regularly (at least once per year) and should contain the following:
*current information on the presence and condition of asbestos items
*information when any asbestos items are removed
*any new asbestos items found when new areas are surveyed.

133
Q

Partial possession vs Early use

A

Partial possession - Agreed post contract and enables PC / contractual obligations are passed to the contractor.

Early use - Client is allowed access, but does not impose the contractual changes / PC

134
Q

Modular construction

A

Modular construction is a way of building structures with prefabricated units or modules that are assembled on site.

135
Q

Modular construction advantages

A

Faster construction
Lower building costs
Requires fewer workers
Reduces waste
Causes less disruption around the building site
Greater worker safety
Improved productivity
Increased schedule certainty

136
Q

Modular construction disadvantages

A

issues with transport and storage - Can cause issues such as shown with Legal & general mould issue

Limitation in size of modules based on transportation

Not suitable for all locations - ie irregular shaped plot

changes post factory are difficult

137
Q

CTM considerations

A

CTM measures are implemented to reduce the vulnerability to threat.

Threat level will influence measures in place.

On my projects it includes, blast proof windows, if a new build consideration to stand off distances ie BZN had to be 30 M due to facility type and location, Combermere 1.5M, access control into building and or barracks, use of CCTV.

138
Q

CDM - what is it

A

Construction Design management regulations 2015

139
Q

CDM regulator

A

HSE

140
Q

Design development vs design change

A

Design development is a progressive stage that focuses on refining and evolving the design concept from the initial concept to a more detailed and resolved design solution. Design change, on the other hand, involves making modifications or adjustments to the design after it has been developed and approved, typically in response to unforeseen circumstances or evolving project needs.
