Q

Why would you involve the project team in reviewing O&M’s? Which members of the project team would you involve?

A

I would involve all key members of the project team.

The project team can review the information included within the O&M’s and ensure this is accurate and aligned with the what is built on site and what was specified within their design.

Q

Why is important that the O&M’s are reflective of the works completed?

A

Accuracy is important as the O&M’s will likely be used to inform future works / maintenance within the building. Inaccuracy could cause additional cost / health and safety risks.

Q

Did this new roof terrace require planning approval and why?

A

The roof terrace did require planning approval as its formation required major works to the external envelope of the building. The terrace was also in very close proximity to the St Paul’s view lines. This was as advised by my planning consultant.

25
How many contractors did you tender to and how did you ensure they were adequate to complete a complex job of this nature?
I tendered to four main contractors. I ensured they were adequate to undertake the works by assessing case studies from similar projects they had undertaken. My QS reviewed their accounts to ensure they were of adequate size. I had also worked with all four previously on projects of a similar nature.
26
How did you ask the contractors to provide these proposals within the tender?
Within the tender documentation.
27
Why did the building need to be waterproofed if a whole building refurbishment was being undertaken?
Water ingress could have caused significant damage to the floor slabs, steels or electrical services still within the building. Further H&S considerations for the contractor also.

The small retaining wall was constructed across necessary areas of the floor to prevent water ingress across the building.
29
What is bunding?
A small retaining wall that is constructed to retain water within a designated area.

Adequate bunding and a waterproofing treatment to the slab were applied to ensure that no damage was created by the water.
31
How did the water drain? Was their a slop to the existing drainage stacks?
Some additional wholes in the slab were created to assist the flow to the drainage stacks. There was adequate drainage points to prevent water sitting on the slab.
32
How did you ensure the existing stacks were sized adequately to allow all rainwater to flow away?
This was assessed by my services engineer to ensure that the stacks were adequately sized.
33
How did you appoint the main contractor for 95 QVS?
Under an amended JCT 2016 Design and Build Contract.
34
Which members of the project team were involved in this review of the proposed temporary waterproofing solution?
Architect, services engineer, structural engineer, planning consultant.
35
How did visiting sites where installed ensure its suitability? Was this the only checks you undertook prior to approving this approach?
It allowed us to view the waterproofing installed on other sites and functioning accordingly. We also spoke with those on site to understand what the product was like to work with and the protection it provided. We also held a meeting with the sub-contractor allowing them to present the document to our team from a technical perspective.
