Q
  1. Efflorescence

Brickwork

A

Efforescence -essentially- salt reacting with water and leaving white mars on the brick

  • could be damaged overtime? can lead to moisture problems causing structural damage to building materials. Can cause structural damage over time

White marks caused by hydroscopic salts in the brick work

It is formed when water reacts with the natural salts by way of chemical process, contacted within the construction material and mortar

The water dissolves the salts which re then carried out and deposited onto the surface by the natural evaporation that occurs when the air meets the surface of the wall

38
Q

Building Defects

A

When inspecting a building you should always be looking for defects –> Start at the roof and work down in a logical sequence.

Understand the purpose of SNAGGING a newly built property –> BONHILL WCS

An inherent defect is a defect in the design or material which has always been present

A latent defect is a fault to the property that could not have been discovered by a reasonably thorough inspection

Can check whether there are any warranties for the building from the contractor and professional team

39
Q

What occurs after a new building is completed?

A

You undertake a snagging process, whereby the property is inspected against the construction plans to check that it has been finished correctly and that the construction is of sufficient quality to ensure the building operates as desired and designed.

This process is carried out by a contractor under warranty. E.G. BONHILL

40
Q

What do you do if you identify any building defects during your inspection

4 steps:

A
  1. Take PHOTO of the defect –> Travelodge
  2. Try to establish the CAUSE of the damage whilst on site —-> The spalling brick which caused movement/internal damp
  3. INFORM CLIENT of your investigation –> Forwarded report onto client to review
  4. Recommend ADVICE from a building surveyor or in the case of movement, a structural engineer.

–> I recognised my limitations / limited knowledge so client instructed a building surveyor and consequently a

41
Q

Three common causes of defects

A
  1. Movement
  2. Water - sometimes leading to damp
  3. Defective / Non-performance / Deterioration of the building material (Common Building Defect)
42
Q

Movement

A

Thermal expansion / movement can cause cracks ! L3

Other cracks may be due to differential movement such as settlement cracks

Subsidence is the vertical downward movement of a building foundation caused by the loss of support of the site beneath the foundations.

Heave could be as a result of tree removal and moisture build up in soil - happens when the expansion of the ground beneath the building

Horizontal cracking in brickwork may indicate cavity wall tie failure in a brick wall

43
Q

Damp

A
  • WET ROT caused by damp and timer decay.
  • Signs include wet and soft timber, a high damp mater reading, visible fungal growth and a musty smell
  • DRY ROT is caused inside by fungal attack.
  • Signs include fungus, mushrooms, strong smell, plus cracking paint work. - It can destroy masonry and timber
  • Damp can be caused y leaking plumbing, AC unit and pipework
  • Condensations can be used y a lack of ventilation and heating. Signs include mould and streaming water on the inside

51
Q

RICS Guidance Note of Contamination the Environment and Sustainability 2010 – best practice for looking for contamination

A

This remind surveyors of their obligations to obey the law, typical signs of contamination,

Signs of contamination include - oil drums, oil, chemicals, subsidence

52
Q

Three typical phases of investigation for contamination:

A

(1) Review site history (desktop study) and site investigation and inspection

(2) Investigation to identify nature and extent of contamination - e.g. soil samples.

(3) Remediation report setting out remedial options with design requirements and monitoring standard

53
Q

Contamination continued

A

If you think the site has contamination, you should suggest a specialist report.

When doing a valuation of site with contamination
1. Don’t provide advice until specialist report is commissioned

 2. Caveat  advice with disclaimer highlighting this special assumption/issue 

 3. Deduct the remediation costs from the gross site value
54
Q

As a developer what can you apply for if you develop a contaminated site?

Land Remediation Relief – A form of tax relief that gives the company/developer up to 150% corporate tax relief.

to help remedy certain contamination or derelict sites or those effected y Japanese Knot weed

55
Q

What is a deleterious Material, and can you give me two examples of them?

A

A deleterious material is a material that is dangerous to health degrades with age causing structural problems to a building, such as:

  1. RAAC (Reinforced Autoclaved Aerated Concrete) is now classed as a deleterious material

2) High Alumina Cement (undergoes a crystalline rearrangement known as conversion, which results in a loss in strength),

(3) Woodwool Shuttering (generally used in the 1960s is mix of shredded timber and cement, caused inadequate compaction of concrete, meaning reinforced steel sometimes left exposed).

56
Q

What is a hazardous material and can you give an example of a “Hazardous Material”

A

A hazardous material is harmful to health

Materials include:
- Radon Gas,
- Asbestos,
- Lead piping/paint

Recommend a specialist report and make app assumptions in advice

Always check contents of an asbestos register
