Licensed works:

Most high-risk work with asbestos - e.g. Asbestos insulation board (AIB), pipe lagging, loose fibres.

Where exposure is high intensity or non-sporadic

Where the risk assessment cannot clearly demonstrate that the control limit will not be exceeded i.e., 0.1 asbestos fibers per cubic centimeter of air (0.1 f/cm3) (averaged over a four-hour period)

Non-Licensed works:

Low risk work - e.g. Removal and encapsulation of textured coating and cement products

Where espouse is low intensity or sporadic

50
Q

A

Client - appoints PD & PC, ensures they carry out their duties, provides welfare facilities on site, allocates sufficient time and resources

50
Q

What is the difference between an old and modern cavity?

A

Old cavity - 1920s, just two skins on brickwork only. 255mm total thickness. Not insulated.

New cavity - 1960s, brick and blockwork skins. 300mm total thickness. Fully or partially insulated on site.

50
Q

What type of construction projects does this legislation apply to?

A

Applies to any construction project no matter size or type - e.g. new build, demolition, refurb.

51
Q

What are frost attacks?

A

It occurs when the ground freezes causing the soil and cracks to expand then when the weather is warmer it thaws out shrinking it again.

When the process is repeated multiple times, it can lead to larger cracks, this can occur in the walls and foundations of a building.

51
Q

What is thermal bridging?

A

It occurs when there is a connection between the outer and inner skin that is more thermally conductive than the rest of the building envelope.

Leads to internal surface being a different temperature and condensation may form which can lead to mould growth.

52
Q

What is damp?

A

Rising damp occurs when a damp-proof course is not installed properly.

It appears on inner/external walls as tide lines due to the groundwater rising through the porous surface of brickwork.

Penetrating damp can be identified by patches of damp/mould. It is caused by water ingress from problems such as degraded mortar, poorly installed windows, missing roof tiles.

52
Q

What is lintel failure?

A

When they fail it can cause cracking and if left un-repaired could cause structural failure.

Steel lintels can corrode meaning it expands causing cracking.

Lintels can crack due to movement in walls or foundations.

Timber lintels are at risk from rot and damp which would affect the structural integrity of timber.

52
Q

What causes wall tie failure?

A

Rusting of wall ties causing expansion within the mortar and causing cracking within the brickwork, failure to bed the ties properly within mortar joints, insufficient amounts of walls ties or incorrect spacing can cause the external skin of the cavity wall to bow or collapse.

53
Q

What are the remedial works?

A

Installation of remedial wall ties, followed by the removal or isolation of the existing wall ties, is the quickest and most cost-effective solution to wall tie replacement.

Remedial wall ties - Mechanical Expansion, Resin / Grouted, Helical Dry fix.

54
Q

Why might non traditional construction be used over traditional construction

A

Non-traditional construction methods have been opted for over traditional methods due to their cost effectiveness and efficiency due to precast building elements. They incorporate standardisation and repetition of construction.

54
Q

What is the difference between traditional & non-traditional construction methods?

A

Traditional construction uses a linear approach, and the majority of the work is completed on site - also commonly uses masonry or stonework in construction.

Non-traditional construction does not necessarily use a linear approach and a lot of the building elements can be pre-cast or made in factories. Doesn’t tend to use bricks or stonework and will be mostly concrete.

54
Q

What is Rat-Trad construction?

A

Rationalised traditional construction, which is a combination of both traditional and non-traditional construction methods - e.g. Crosswall.

54
Q

Rationalised traditional construction, which is a combination of both traditional and non-traditional construction methods - e.g. Crosswall.

A

The person who has ownership or control of the premises - For PCC it is the director of HNB which is James Hill.

54
Q

What questions would you ask the responsible person?

A

General information - the premises (brief construction details), occupants (ASB, hoarders, disabled), any fire loss experience for the block, any outstanding recommendations/works from previous FRAs.

55
Q

How do you assess the overall risk of fire within a block of flats?

A

Carry out an FRA using the PAS 79 form - looking at fire hazards, their elimination and control.

Inspection of passive fire protection such as doors, compartment walls and fire stopping.

Assessment of adequate signage and fire safety notices to allow safe egress.

Housekeeping in terms of maintaining a clear access route of at least 800mm as per approved document and ensuring no fire loading in or near the block.

Inspecting the communal wall linings to ensure there is no pealing or flaking of paint and ideally this system is class 0.

Travel distances are reasonable and tolerable, safe, and adequate.

No mobility scooters are stored within the communal areas.

Security of the block in terms of boundaries and block entrance door (risk of arson).

Identifying any plastic cable trunking or unsupported trunking in the communal areas.

Inspection of communal roof space in regard to loft hatch integrity and compartment fire walls.

Although outside of the RFSO, property inspection to ensure adequate flat entrance door (self closes), protected internal hallway and compartment fire walls in the roof space.

If there is hoarding in any properties, this could make it harder for residents to escape and firefighters to enter.

Dangerous Substances e.g. oxygen in flats.

Escape lighting - adequate and present, regular testing in place.

External inspection of the construction materials and any claddings.

55
Q

What is their role?

A

They are responsible for appointing a competent person to assist in undertaking FRAs of their property.

55
Q

What is the importance of compartmentation within blocks of flats in the PCC housing stock?

A

PCC operates a stay put policy meaning residents should stay within their flats in the event where there is a fire in another flat within the block - this means compartmentation is essential between flats to ensure the fire cannot spread easily.

56
Q

What are some common actions required to minimise the risk of fire in blocks of flats in the PCC housing stock?

A

Fire stopping to service penetrations, property entrance door replacement, class 0 paint linings, emergency lighting installation, removal of combustible waste/items.

56
Q

How are FRA actions prioritised?

A

Based on risk.

1 - Actioned immediately as a day-to-day repair/bulk waste. (Fire stopping, waste removal).

2 - Within 12 months will generally be planned maintenance or small repair quotation. (Emergency Lighting, Door Replacement, Metal Ties for Trunking).

3 - Would improve fire safety of the block but not immediately essential.

56
Q

What type of FRAs do we carry out and under what legislation?

A

Type 1 non-destructive survey using a PAS 79 form - under the regulatory reform (fire safety) order 2005.

56
Q

How are planned maintenance schemes prioritised for larger fire safety works?

A

Works are prioritised in terms of the level of risk within the block - e.g. High-rise block of flats such as Ladywood house requiring full property entrance door replacement will be high priority and carried out much faster than full door replacement to a 3-storey block of flats.

57
Q

What is the scope of PCC FRAs under the regulatory reform (fire safety) order 2005?

A

The common parts & property entrance doors but no further - does not cover internally to individual flats.

57
Q

What are the principles of work and how have you used them in the repairs team?

A

Customer sets nominal value - I arranged a convenient appointment for customer for a RTB survey, turn up as agreed and complete all survey requirements the first time - no need for a revisit.

Work flows 100% clean - I ensured work handed onto the next step of the workflow is perfect (no delay due to errors) - My RTB plans were accurate and no errors therefore the RTB officers did not have to send back my work for amendments and can continue with the process quickly.

Single piece flow - Picking up a piece of work take it to completion without picking up another item from the flow - I completed an FRA from desk study, site visit survey, and write up sending out relevant actions all in one day with complete focus on the task with no interruptions.

58

60
Q

What are three types of damp

A

Rising
Penetrating
Condensation

60
Q

What issues can repointing old brickwork in cement mortar cause?

A

Older lime mortar needs to breathe as it is porous, to let water out. If concrete mortar is applied over top it traps moisture and it will try to escape through brick which will then spall the bricks as they are saturated (freeze-thaw)
Also concrete can be too strong compared to flexible lime mortar and wont let the building move a normal amount causing extra cracking in brick or foundations

61
Q

What is a cavity tray?

A

Cavity trays are a DPC that is used to direct any moisture within a cavity out of weep vents. They are often used on top of windows, doors or any openings. It is like an internal gutter for the cavity allowing moisture to escape and not sit on the internal leaf.

61
Q

What is cold bridging?

A

This is where there is a gap in the insulation, which often causes condensation on the colder areas.
It could either be from debris in a cavity, or often where elements of buildings meet e.g. floors to walls, walls to ceilings/roofs

62
Q

What are two types of rot

A

Dry rot is a wood destroying fungus that grows in timber with excess water around 20% moisture levels, it can spread all throughout the building, and is identified by a damp smell, fine strands of spore dust and wool like fungus.

Wet rot is similar, but is in timber with higher moisture levels around 30-60%, wet rot cannot spread all through the building and is localised to where the excessive water is. It can be identified by dark, spongy timber with a damp musty smell.

63
Q

What do you mean by 3ft 6in module?

A

Module is adopting a regulated dimensions for the building, repeated sections called
modules. BSIF house, 3ft6inch module, floors are 7ft, stanchions/beams/joist laid
3ft6inch.

63
Q

What is a common defect to a solid concrete floor

A

Hardcore under the concrete slab can have settlement (if not correctly compacted) which may result in movement meaning the concrete could crack, or the hardcore could expand/swell in moist conditions which again could crack the concrete.
Steel reinforcements corroding, expanding and cracking the concrete
Sulfate attack, sulfates in the hardcore could react with the concrete and create crystals which expand and crack the concrete

63
Q

BISF common defects

A
  • Corrosion of steel frame - stanchions (vertical columns that provide structure with
    support)
  • Corrosion of rag bolts that hold stanchions is common, cracking on in situ concrete
  • Corrosion of sheeting rails, hold cladding in place, causes bolt to protrude outwards
  • Corrosion between top two cladding sheets on gable wall, weathering strip that is in
    place to stop weathering entering through the joint also failure and can corrode.

64
Q

Briefly explain the construction of non-traditional construction type (BISF & Another)

A
  • Steel frame cheap / easy alternative to building houses post WW2
  • Foundations - Strip -> 9-inch wall -> in situ concrete (4inch ,9inch over brick)
  • 3ft6inch module design, stanchions rise to eave level space at 3ft6inch intervals
  • Front/rear elevation, 7ft gap to house windows
  • Stanchions supported by steel supports and ceilings joists, which are spaced at
    3ft6inch interval (eaves wall), supported by floor beams, spaced at 3ft6inch intervals
    and rafter ties (gable wall)
  • Corners of BISF house had diagonal support, where gable/eave wall met.
  • Timber noggins where notched at each end and slotted between the floor beams
    and ceiling joists, to provide fittings for floorboards, and plasterboard.
  • Roof - truss design of steel RS angle, 3 trusses laid which were joined via steel
    purlins. Corrugated cement asbestos roof panels where used attached to purlins.
  • External wall - cavity wall - ground floor was cement render applied to metal mesh,
    which was attached to steel frame. First floor - galvanised cladding - fixed to
    sheeting rails.
  • Internal linings - timber frame secured to steel frame - plasterboard fixed - Glass
    fibre quilt between timber/steel frame.
  • Party wall - cavity breezeblocks
  • Partitions wall - timber frame with plasterboard.
65
Q

2) What is in-situ concrete?

A

Concrete that is laid on site, it is poured into shutters, mould, where it is left to set

66
Q

What do you mean by RS angle in shape?

A

L-shaped metal beam

66
Q

What is a stanchion?

A

Vertical posts/beams that are used for support structure

66
Q

What are rafter ties?

A

Rafter ties are used when ceiling joists do not provide restraint for the rafters, the
rafters ties are used to support the rafters to provide them with restraint, triangle.

67
Q

What are rag bolts & barbs?

A

Rag bolts - a bolt with barbs that is used to attach objects to concrete. Barbs keep it
tight once it has been driven in, hinders withdrawal.

67
Q

What do you mean by RS channel in shape?

A

U-shape

68
Q

What way to first-floor beams face?

A

The first-floor beams run parallel to gable wall, every 3ft 6in

68
Q

What way do ceiling joists run?

A

They run parallel to eaves wall, which is why rafter ties are necessary as the joist do
not provide restraint in the roof.

69
Q

How are the RS joist floor beams supported?

A

They are supported by the stanchions, and also supported mid span by 5x3.5 inch RS
joist spine beam, the joist spine beam is supported by 7ft post made from 2 2in RS
angles welder together to make a tube.

69
Q

Briefly explain the construction of roof in BISF house?

A

Truss roof, 3 or 4 trusses are laid joined together via purlins. The ceilings joist is laid
parallel to the eaves wall supported by the stanchions. Rafter ties are used to give
the truss rafters restraint. Corrugated asbestos cement roofing is attached to
purlins.

69
Q

What are timber noggins, and what do you mean by notched?

A

Strut that provides rigidity between frameworks.
End of timber noggin is shaped so it can fit/slide into joist/beam

70
Q

Briefly explain the external wall of a BISF house?

A

Cavity wall - ground floor - metal mesh attached to steel frame; cement render
applied to mesh. First floor - galvanised cladding attached to sheeting rails.

70
Q

How would you deal with room in roof?

A

Permanent staircase is fitted
Common wall is less than 1.8m for over 50% of walls then it counts (exclude
gable/party)

70
Q

hat were the internal linings of a BISF house?

A

Timber frame is attached to steel frame, plasterboard is attached to timber frame.
Partition walls are timer frame with plasterboard.

70
Q

What is a glass fibre quilt?

A

Type of insulation, made from recycled glass fragments and sand.

70
Q

Difference between party and partition wall?

A
  • Party wall - shared/dividing wall by 2 adjoining buildings that is shared by occupants
    of each residence/business.
  • Partition wall - solid/framework/stud walls - nonloadbearing, that separate spaces
    within buildings - only support themselves.
71
Q

What is cement slurry?

A

Slurry - solids in liquid - mixture of cement, water and additives - when it applied to
sets and solidifies

72
Q

Retrofitting to design? Refurbishment

A
  • Most common type - replace cladding at first floor level
  • Changing the windows to increase light and attractive ness
  • Update insulation (1inch glass fibre quilt) - solution I read external insulation in form
    90mm thick graphite expanded insulation boards - finished with a render
72
Q

What is the Housing Defect Act 1984?

A
  • Legislation that applies to defective properties that were built by local authorities
    and allow owners of these properties to allow for a grant under the scheme.
  • BISF does not come under the act
72
Q

What is a cold and warm roof

A

i. Cold - insulation is placed above the ceiling between the joists, vapour later
laid under insulation and adequate ventilation for void above to stop
moisture condensing on timbers which could cause rot
ii. Warm - insulation is laid above the joists on the deck, either above
(inverted) or below (sandwich)waterproof membrane, this keeps the void
the same temperature of the building so little chance of condensation, no
chance for timbers to rot due to condensing. Vapour layer still laid to
minimise moisture movement.

73
Q

When did EPC become required?

A

October 2008

73
Q
