Case study Flashcards
Can you name other procurement routes?
Design and build
Management procurement
Why did your client not opt for traditional procurement competitive tendering?
Early contractor involvement required
Client required price surety
Competitive tendering would increase time requirements and client wanted work done ASAP
Are there time and cost implications using competitive tendering?
Yes design would need to be complete and the design and construction cannot overlap.
Competitive pricing can be an advantage however greater time is required.
How did you ensure the level of was pricing was satisfactory for negotiating the tender?
Once submitted the price was negotiated by the project qs.
What information does the project qs use for pricing “?
Bcisand in house rates
What is a pre construction agreement and why was this utilized?
This is allows the client to employ the contractor prior to the contract. It enables significantly more contractor collaboration for elements of the design.
What are the advantages of using a pcsa?
Construction risk decreases as the contractor uses their specific knowledge to improve build ability
Why was the intermediate contract chosen over minor works?
Allows collateral warranties Allows a pcsa Greater control procedures Allows sectional completion Allows partial possession
What other consultants were appointed on the contract?
Hoare lea Plymouth m&e consultants
T&g engineers
What were the services provided by the structural engineer?
Scaffold fixings, some were missing and the o and Marion did not have information on lateral loadings. They tested this.
They also provided ser services for the fire ducts and later the louvre screening and also the design for the new roof.
What formed the contract documentation for the project?
Jct intermediate contract with cdp with amends for jersey law
Bhp contract drawings
Bhp preliminaries
Hoare lea basement car park ventilation specification
Ac Mauger priced tender
What documents were provided to the contractor detailing the design?
Hoare lea basement car park ventilation specification for tendering to their sub contractor. This formed their cdp portion. Also bhp speciation
What is the governing health and safety legislation in jersey? What was the effect on the project?
Management in construction jersey 2016
Defines project as a major project Required a hspc Requires pcsi Requires healthy and safety file Hspc also approves construction phase plan and prepares a f9 notice
What was the flat roof finished with and what were the defects?
Sika single ply adhered to insulation
This was de bonded
Spoiled with no routine maintenance
Approximately 100 tears leading to water ingress
What is a Granite Rain Screen?
Cladding attached to primary structure
Forms ventilated system
LW4 was ventilated
What is Grade A Office Space
Offices in best locations
best building materials
Professionally Managed
What is traditional Procurement?
This is when the design and construction are separated
For LW4 explain the tendering process and the procurement option?
Explain why each were used
This was traditional procurement
Negotiated tender
The client wanted to ensure they retained full control of the works. The building was in use and they needed to ensure a PM and CA mitigated ‘heavy handed’ works on site.
Negotiated tender was chosen because of AC Mauger track record.
Traditional Method of procurement with negotiated tender? Explain how this worked?
The design and construction were separated for the benefit of client control. The PCSA allowed the contractor to be employed prior to the contract to enable full collaboration on design issues.
What is a disadvantage with using a traditional procurement with negotiated tendering?
No comepetition to comparison.
Why didn’t the client opt for 2 stage tendering?
AC Maugers track record with my client.
Why was design and building procurement route not suitable?
The contractor may not fully understand the requirements.
Sensitivities of a fully occupied Grade A Building
At what RIBA stage is a contractor
normally invited to tender in traditional procurement and why?
At RIBA Stage 4 (Technical Design). This is because traditional procurement requires all design to be complete prior tendering.
What are the advantages of traditional procurement?
Higher Quality of work as the client has more control
Easy to adopt
What are the advantages of negotiated tender?
Early contractor involvement
price can be returned faster
contractor involvement in the design
What is the disadvantage of the negotiated tender?
Lacks competition and comparative analysis although the Project Quantity Surveyor can help mitigate this disadvantage
Why a 2011 contract?
The PCSA was entered into prior 2016
Legal advice was sought by client in
house council who advised us to proceed under the current Jersey ammends.
Why have CDP?
This is to enable contractor to procurement and detail specialist design.
Explain how the CDP portion worked on LW4?
Hoare Lea plymouth the M&E consultant provided the client with a performance specification for the car park smoke extract fans
The contractor then had the responsibility to procure the works which they took responsibility for.
What works consisted for the CDP portion?
Car Park smoke extract ventilation fan
What other options were there for remediation to the roof and why was this not possible?
Patch repair however because of the extent and because the smoke extract fan required removal and reinstatement meant that it did not make economical sense to do this.
What was wrong with the plant detailing prior to the works at LW4 and how was it leading to water ingress?
The plant was on top of a big foot louvre system, however the foot pads did not spread load sufficiently and had penetrated through the single ply membrane.
Why was it not comprehensive?
The M&E consultant advised the car park ventilation system was not adequate
How did you find out the building was not compliant with the smoke extract?
During the pre acquisition stage a review of the O&Ms indicated some information was missing. This was followed up with Building Control who confirmed that there was no information on the smoke extract.
How did the M&E consultant find work out the basement ventilation was not compliant?
They ran a computational fluid dynamics analysis.
How did you comply with the Surveying Safely guidance note?
Conduct pre assessment of likely risks
Ensured lone working provisions were made
Ensured i had appropriate PPE
Ensured suitable protection was in place to protect from falls
What is the difference between sectional completion and partial possession?
Sectional completion defines practical completion of a section within the contract.
Partial possession allows the employer to use part of the works for intended use prior to completion.
Was there sectional completion at Liberation House?
yes, this was for the fire rated duct and the disabled WC areas on each floor.
