Works Progress And Quality Management Flashcards
What case law do you know of that relates to interim works inspections?
Ian McGlinn v Waltham Contractors
6 principles of inspection came out of this case
Main one is inspections should be tailored to the program, not just weekly for example
What are the terms in the JCT MW contract regarding quality of workmanship?
Section 2: Carrying out the works
- “Contractor to carry out work in proper and workmanlike manner”
- quality of materials/workmanship are a matter for the CA’s approval, and his “reasonable satisfaction”
In what circumstances might a project require more frequent site visits? Give examples.
A particularly sensitive part of the works, eg:
- Fire compartmentation and fire stopping prior to the enclosure of ceilings
- Inspection of roof underlay before final covering goes on
- Inspection of balcony falls before decking goes down
- In between coats of paint to ensure all is painted on
Give me some examples of the quality standards you include in your specifications.
Lead Sheet Association Manual
British Standards Codes of Practice (masonry, waterproofing, joinery, slating, glazing, rendering)
NHBC Design and Construction of Dwellings
Check its done as per manufacturers instructions
How does the contract administrator’s role differ from the role of a clerk of works? Or Employer’s Agent?
CA = impartial. Administering the contract. Does inspect workmanship, but more focussed on adherence with specification.
Employer’s Agent = D&B contract only, aligned with the client, acts in their interests, but still impartial.
Clerk of Works = site-based, inspects works and reports on workmanship, but does not administer contract

Why did you instruct repointing of the lime mortar at Sylvan Avenue?
Sylvan Avenue– The pointing has failed, and the porous brickwork had become badly spalled due to several reasons including constant saturation, plant growth and previous repointing in a strong cementitious mortar. The incorrect type of mortar on this wall has not allowed the bricks to release moisture through normal evaporation causing the brick surface to crumble when freezing occurs. The vegetation has also taken root on the surface of the wall reducing moisture evaporation. Prognosis: Total saturation and eventual collapse. Remove all vegetation effecting the wall and either reface or remove and replace effected brickwork. Then rake out all mortar joints to a firm depth and repoint in a Lime based mortar to allow the wall to ‘breathe’ more efficiently.
Sylvan Avenue: How do you know the wrong mortar mix is being used?
: Look carefully at the mortar mix to see if it is the correct strength. Suspicion can be raised by the colour of the mortar. A very grey bland and smooth face suggests too much cement. A sandy yellow martar where the colour omes off in the fingers and the face is gritty and can be eased of with a fingernail will suggest a sandy mix. A pale yellow white putty colored mix of granules which can be rubbed away with by the finger suggests a lime mortar mix.
