Summary of Experience

A
  • Home Report of flat in Hardgate - damp staining was recorded to ceiling around chimney breasts. Plaster was beginning to loosen and fall. Used a protometer to measure moisture levels. Followed trail outside and inspected roof, especially areas adjacent chimney breast. Skews were in bad condition. Concluded that water was likely to be entering via damaged skews and into flat.
  • Home Report of flat in Fraser Street - Inspected bathroom cupboard and noticed deterioated flooring adjacent hot water cylinder. Flooring was lighter in colour and displayed high moisture meter readings. Flooring was brittle. Concluded flooring was likely to be affected by wet rot caused by the cylinder leaking.
  • Home Report on cottage in Drumlithie - Scattering of small holes were noted to timbers within roofspace. Concluded that it was wood boring insect infestation.
119
Q

What are your level 3 examples?

A
  • Home Report of flat on Skene Street - Rot was noted to doorframe in communal hallway. Door drame suffered cuboidal cracking and was dry and crumbly to touch. When inspecting other side of door fruiting bodies were noted. Concluded rot was most likely dry rot and informed client. Advised client that dry rot is a serious defect that can result in costly repairs and restricted lending/saleability issuses. Advised client to instruct timber specialist to establish extent of outbreak and prepare schedule of remedial works required.
  • Home Report on flat on Great Western Place - Obvious structural movement was recorded internally in the form of off level flooring. Externally there was areas of stepped cracking. Previous remedial works had been carried out in the past to secure the toilet stack to the main building. The rear had been repointed at some point and the pointing had opened up again. Informed client that structural movement was evident and was unable to confirm whether or not it was long standing. Informed the client that structural movement is potentially a serious defect if its ongoing and it can lead to restricted lending and saleability. Advised client to instruct a structural engineer to investigate the nature of the movement and prepare a scope of works if required.

Q

You are level 3 Building Pathology and Property Inspection. Can you provide experience and examples of work you’ve carried out to level 3 in these competencies

A
181
Q

Can you discuss the 3 different types of cracking that can occur as a result of structural movement?

A
  1. Tensile - Occurs when materials are pulled apart from each other
  2. Compressive - Occurs when materials are compressed togther
  3. Shear - Occurs when perpindicular force is applied
182
Q

Can you talk me through the various signs of structural movement

A
  • Cracking
  • Misalignment - sloping sills, lintels, masonry coursing and floors
  • Windows and doors don’t open/close property and fractured service pipes
  • Environmental clues such as sloping ground, damage to other properties in the locality
183
Q

Can you discuss the considerations that are given to cracking when establishing the nature of structural movement?

A
  • Type of crack - is it tensile, compressive or shear
  • Width of crack and whether it tapers along its length
  • Where the cracks are disturbed around the building
  • Whether the cracks extend through the width of the wall and appear internally
184
Q

Can you discuss the various evidence of foundation failure?

A
  • Cracks affect internal and external faces of walls in close proximity - especially true in cavity walls as foundation movement is one of the few processes that can cause cracking in both leaves of a cavity
  • Damage extends down below DPC and into ground - when support benath foundations is removed or weakend the building will virtually break and rotate around the focus of movement
  • Cracks are normally tapered, wider at one end than the other - as the building normally rotates cracks tend to be wider at one end
  • Cracks are usually wider and more frequent, closer to the point of movement
  • Cracks are normally diagonal
  • Floors and walls tilt and openings distort, causing them to bind in their frame
  • Cracks tend to travel through openings - openings attrack cracks as they find them easier to travel around weak points
185
Q

What is normally the cause of diagonal cracking?

A

Foundation failure

186
Q

What normally causes horizontal cracking?

A
  • Cavity wall tie failure
  • Sulphate attack
187
Q

What normally causes vertical movement?

A
  • Thermal movement
  • Moisture movement
188
Q

What is deemed as recent movement?

A

Occuring in the last 5 years

189
Q

How can you establish if movement is recent?

A
  • Enquire as to when the property was last decorated
  • Recent cracks will look fresh with crisp, sharp edges
  • Old cracks will appear erroded, worn and dirty
  • Damage on elevations facing prevailing winds will age quicker
  • Older interal cracks may have emulsion or paint inside
  • Look for evidence of repairs that have opened up again
190
Q

Talk me through your five step plan for investigating structural movement

A
  1. Spot triggers
  2. Investigate triggers and establish extent of damage
  3. Classify damage - does it cause aeshetic, serviablilty or stability
  4. Establish the likely cause and whether the damage will get worse
  5. Decide whether the movement requires further investigation
191
Q

Discuss repointing in regards to structural movement

A
  • Repointing is the most basic level of repair for structural movement once the defect has been resolved
  • Difficulty lies
