Subsidence is due to external factors where as settlement is a design flaw.

Sulphate Attack at Withernsea
How was that concluded what happened in the end?
Following an on-site inspection I advised my client to remove the floor slab and sub-base.
Sulphate Attack at Withernsea
What was your diagnosis?
Visual assumption indicated towards sulphate attack to the concrete floor slab. The slab was at a point in which immediate replacement was required.
Sulphate Attack at Withernsea
Are there any other further investigations you could be doing before going from a visual analysis to breaking out the slab?
You could undertake a test. ???
Construction Technology
How do you calculate the u-value?
First you work out the R-value of each material by doing the following:
You workout the resistance of a material by dividing the thickness by the thermal conductivity.
The U-value is then worked out by adding up all the total R-value and dividing by 1.
Construction Technology
What checks might you do for a flat roof build-up?
U-value
Interstitial condensation
Construction Technology
Did you think the lightweight walls are relevant to a raft foundation?
Construction Technology
What is the primary reason you might use a raft foundation?
Contract Administration
What is the differences between NEC and JCT?
NEC:
Project Manager
Programme always need to be up-to-date
Early Warnings for both PM and Contractor
Contract Administration
You recommended a tender evaluation of 90/10 split. How did you evaluate the quality element?
I evaluated the contractor on his employment skills plan, method statement and programme.
Contract Administration
How did you work out the tender evaluation scoring?
There’s an equation that you follow i.e:
very good programme you may give them a 9 or 10. Very poor you may give them a 2 or 3.
Contract Administration
Are there any rules outside of the contract that are applicable to payments within construction projects?
The ‘Housing Grants, Construction & Regeneration Act 1996’ also known as the ‘Construction Act’
Contract Administration
How does the Housing Grants, Construction & Regeneration Act 1996 affect you in terms of payments?
If the work is expected to be longer than 45 days, interim payments must be made under the act.
Under the NEC (21 day cycle)
- Contractor submits their application for payment
- Over next 7 days, PM assess the application
- PM has 5 days as stated in the act to submit their interim payment certificate to the contractor (Notified sum and final date for payment)
- 9 days Final date for payment. Final date before a contract can envoke section 112 of the HGCR Act (right to suspend performance due to non-payment)
If the employer/PM fails to provide an interim payment certificate within 5 days of the due date, the contractor application for payment becomes known as a ‘default payment notice’ under the HGCR Act
Assessment Period - 7 days
Prescribed Period - 14 days
Contract Administration
What is a Payless notice?
If a client intends to pay less than the sum assessed or provided in a valuation then there is a statutory requirement under the HGCR Act 1996 that any party intending to pay less, has to present a pay less notice.
Contract Administration
You have a job on-site and an interim payment lands on your desk the day you’re due to go on holiday. What is the primary risk under this legislation?
Default payment notice.
Design and Specification
Can you tell me the difference between a performance specification & prescriptive specification?
Design and Specification- Prescriptive/Performance
What are the pros and cons; when might you use one over the over?
Design and Specification
At Hallgate Primary School, you said you did a disabled WC; did you get involved in the drainage?
Yes - drainage was already in place.
Design and Specification
Do you get involved in ramps; what is the building regulations requirement for external ramps?
Domestic - its Approved Document M Volume 1
Non-Domestic - Its Approved Document M Volume 2
Design and Specification
You said you were involved in specifying some internal work to a corridor; what did you do?
To get to one of the classroom you have to pass through another classroom.
The school wanted to introduce a corridor but no impede on the existing classrooms.
