Works Progress and Quality Management

Question 1

What case law do you know of that relates to interim works inspections?

Answer 1

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

Question 2

What are the terms in the JCT MW contract regarding quality of workmanship?

Answer 2

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”

Question 3

In what circumstances might a project require more frequent site visits? Give examples.

Answer 3

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
If the client demands it, ie. if it is a sensitive case (eg Sunnyhill Court!)

Question 4

Give me some examples of the quality standards you include in your specifications.

Answer 4

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

Question 5

How does the contract administrator’s role differ from the role of a clerk of works? Or Employer’s Agent?

Answer 5

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

Question 6

How is quality shown or described within the contract documentation?

Answer 6

Prescriptive, measurable characteristics (eg. Flat roof not to exceed 1:80 falls at any point).
Will specify materials, may reference manufacturer’s instructions or data sheets.
In accordance with NHBC standards for example. Or British Standards, Codes of Practice.
