Case study questions Flashcards
Can you talk me through the construction of Freshwater Court?
Fresh water court is of cavity brick construction with hollow beam concrete floors and a timber flat roof
How are you able to consider the age of the building?
I review old maps and photographs as well as the style of construction
What challenges did the location of the building have on your project?
As the building was situated in an exposed seafront location it was particularly prone to prevailing south westerly winds.
What caused failure of the roof?
In this case there was a strong south easterly wind during a storm. The UPVC trims and roof covering were stripped back.
How did you go about checking for potential conflict of interest?
I used our conflict of interest check form which ensure I had no vested interest in the building, I had no relationship with the client, leaseholders, managing agent or loss adjuster.
How did you go about preparing your specification?
What was the requirement to take samples?
Why was wood wool slabs a risk?
Wood wool slab is classed a deleterious material as voids can form around the reinforcement. HSE Health and safety in roof work (Fifth Edition) also class them as fragile decks especially when exposed to water penetration. If retained fixing of insulation can be problematic and replacement will require structural engineering design.
Why was the roof deck able to be retained?
The roof deck was found to be 18mm ply wood and was found to be dry in all areas where samples were taken.
Why was it not a requirement to meet current building regulations
Why would a high-performance buildup felt system have been appropriate?
How did you go about calculating insulation depth?
What implication with the new parapets heights had on planning?
What association warranty would you have achieved with option two?
Why was liquid applied system suitable?
What had caused does the bubbling?
What had caused the corroded fixings?
The fixings were a galvanised type which corrode over time exacerbated by the coastal location.
How was your budget cost prepared for the various options?
I used Bcis coatings and previous roofing projects
Why did you invite four contractors tender?
I invited 4 contractors to tender as the project was small and, needed a quick turn around and was coming upto a busy season. this worked well as one contractor failed to return meaning I had 3 valid tenders.
How did you go about calculating the contingency sum?
I used information from previously completed projects as well as using u value calculation
Under option one who would’ve taken the design risk?
The design risk could have been allocated to the employer or the contractor depending
What are the pitfalls of letter of intents?
Can you talk me through the principles of the JCT repair and maintenance contract?
Why did you rectification period would be beneficial to the client?
Why did you select JCT minor works compared to intermediate works?
The project was simple in nature with a contract sum of 43000 plus VAT.
How did you assess the contractors design?
What insurance did you need to ensure?
Can you talk me through one of the design details?
Can you talk me through a challenge that you experienced whilst the works on site?
Reflecting on the project can you taught me through other systems you may have explored?
Prior to tender I explored suprema and moy felt systems, I also investigated polyroof liquid applied system. Following the tender analysis I explored bailies and DANOSA systems.
What would you do differently next time?
How did you act ethically?
I could have recommended a complete roof replacement or repair given the unknown history of repairs which would have provided certainty over future repairs. This would have added significant cost to the project and as I was on a percentage fee, would have also increased my fee, however, this would not have been ethical. I could have also exaggerated the cost for repairs to the insurer to gain the client more funding.
What were your key achievements?
I completed the project to the satisfaction of the client and the stakeholders,
