Q

What does RICS Information Paper on Japanese Knotweed and Residential Property March 2022 outline?

A

Purpose - Address both the findings and provide best practice guidance on the recent research about a more hollistic assessment of Japanese Knotweed. To ensure RICS members provide the best advice to users of valuation and condition reports.

Decision tree - Based on risk level to help valuers determine the app management approach needed for JK

Process - The new process still delivers a straightforward and objective catergorisation of JF infestations. To provide clarity that is essential for lenders and will continue to ensure confidence and trust among the wider stakeholder

Q

What are the four common forms of foundation?

A

Choice depends on ground conditions and building loading’s

  1. Trench or strip footings - resi dwellings for walls and closely spaced columns
  2. Raft - slab foundation over the whole site to spread the load for lightweight structures such as for made up/remediated land and sandy soil conditions
  3. Piled - long and slender reinforced concrete cylinders (piles) in the ground to deeper strata when less good load-bearng ground conditions - high loads
  4. Pad - Slab foundation system under individual system under individual or groups of columns so that the column load is spread evenly

Q

What is horizontal crack and shrinkage cracking?

A

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

S - Shrinking cracking often occurs in new plasterwork during the drying out process

Q

Efflorescence

A

White marks causes by hydroscopic salts in the brick work

Formed when water reacts with natural salts by way of a chemical process contained within the construction material and mortar

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