Q

What is the difference between Licensed vs non licensed and notifiable

A
  • Licensed asbestos removal is work that needs to be conducted by an HSE-licensed contractor because the risk involved is deemed to be high
    -Non-licensed asbestos removal means that the contractors do not need to be HSE-licensed to carry out the work as it is classified as lower risk - e.g. removal of floor tiles, textured decorative coatings- they still require training
  • Notifiable non-licensed asbestos work is removal area was large or if the project involved working with asbestos cement that was in poor condition

Q

When a variation occurs how do you tackle it ?

A

So the contractor may raise a early warning or CE - if it requires a site visit i would undertake one to check what the contractor was claiming was correct. Contractor instructed to submit a quote - 3 weeks - contractor question - 2 weeks - the PM responds

Q

Why does NEC use CE instead ?

A

They do not treat compensation events as an allocation of blame, but rather an allocation of risk. Any risk that is not specifically identified as being attributed to the client is borne by the contractor.

Q

What is the difference between partial possession and sectional completion ?

A

Sectional Completion = different completion dates for different sections of the works allowing the client to take partial possession of the completed parts whilst construction continues - Multiple completion dates - each section must be clearly defined and the amount of retention released for that section must specified for each section. Follows the usual handover procedures. Some work in the section may remain outstanding such as completion of commissioning as built ect which will cross over sections

  • Half of the retention is released for that section.
  • The Rectification Period begins for that section,
  • The contractor’s responsibility for insuring the works (if applicable) ends for that section.
  • The contractor’s liability for liquidated damages ends for that section.
    The employer is now responsible for any damages to the works for that section.
  • Difficulties with logistics on site when different sections are in the possession of different parties.
  • The protection of completed sections from ongoing work.
  • The provision of appropriate insurance at all times for all sections.
  • The adoption of appropriate health and safety measures to deal with risks resulting from occupation of areas adjacent to, or only accessible through ongoing construction works.
  • The provision of appropriate security measures.

Partial Possession = the same as sectional but after the contract documents are drawn. The contractor is not obliged to allow partial possession (although PP cannot be unreasonably withheld) and may not wish to e.g. access routes are difficult to achieve, disrupt the works, incur additional costs - occupants may disrupt the works which could result in a claim for an extension of time and/or loss and expense

A

The Provision and Use of Work Equipment Regulations 1998 - states that work equipment should be inspected at regular intervals. There isnt any defined number. The inspection regime was eventually agreed through a dedicated workshop with a number of people; including H&S managers, Structural Engineers, client reps and contractor (at the time MITIE). That workshop enabled us to gain a general consent and develop a design risk assessment to satisfy all parties.

41
Q

What type of concrete was the floor ?

A

cast in situ - had to avoid formwark and reinforcement - h

42
Q

Whats the difference between pre cast and cast in situ concrete and whats the adv and dis of each ?

A

Precast concrete is a good choice for large structures, such as bridges and water quality systems. Precast concrete is manufactured in a factory then delivered to the construction site, where it’s assembled. This process makes it easier to transport large pieces of precast concrete, which saves time and money in the long run.

Precast concrete is also strong and durable because it doesn’t need to cure like other materials do, meaning you won’t have to wait months before putting your building up. Precast concrete can be used for many different projects due its high strength-to-weight ratio and resistance against fire or water damage

In-situ concrete is a process of casting concrete in position. It is used for foundations, walls and floors. In-situ concrete can also be used in areas where it is difficult to transport materials such as certain building sites or underground. - uses formwork

In-situ concrete has many benefits including:

The concrete dries evenly and quickly due to its shorter production time; this means less chance of cracking resulting in a stronger finished product
Substantial structural integrity because there is no chance of drying shrinkage cracking

43
Q

how did you know what type of concrete it is?

A

Could see the formwork/ could see the precast concrete planks formation?

44
Q

What are the potential issue with instructing the drawings know there will be a change

A

conflict, disputes over costs causing time delays

45
Q

How could you determine if a quote from a contractor is fair?

A

Refer to BCIS, Refer to Spoons, refer to original tender submission for similar elements

46
Q

Would the variation be allowed ?

A

Yes because it doesn’t change the nature of works

47
Q

When are variations not allowed ?

A

Change the fundamental nature of the works.
Omit work so that it can be carried out by another contractor.
Be instructed after practical completion.
Require the contractor to carry out work that was the subject of a prime cost sum.

48
Q

Can a contractor refuse to do a variation ?

A

there must be express terms in contracts which gives the power instruct variations. In the absence of such express terms the contractor may reject instructions for variations without any legal consequences then yes they can. But there was an express term in the contract
