The nominated subcontractors Assessment 2022

Assessment task 1
Number 1.1
It is from the nominated subcontractors that the selection of the subcontractor takes place. They are
privy to such document because of pricing, usually they are given when the document is blank.
Secondly, the material schedule contains the specifications of the materials to be supplied or the
nature of work to be done. Lastly, the material schedules tells the nature of work to a sub-
contractor, this prepares them for the potential task ahead and if the sub-contractor wants to leave,
this usually is the time.
Number 1.2
The supplier usually gives the quotation of the materials required for the contract administration.
From these materials, the engineer or construction business forms the rates to include the labour
(which is usually a percentage about 30% of the material cost) (Gachihi, 2013). The reason for
this is it gives a very easy way of quantifying the quantity of work to be done from the materials to
be supplied. Therefore, a bill of quantities of material schedule is generated from the quote of the
supplied materials.
Number 1.3
The changes of the drawings are usually made from the client preferences, or because of
assumptions that were made about the site when the drawings were being done. So that when the
developer or the architect goes to site, they experience the difference of how the site is. Another
aspect that brings changes is the cost, there are things that the developer might deem to be raising
the cost of construction, and therefore would want them removed or their formation changed. These
changes are usually done during the site meetings where the whole team is gathered together and
presented with the changes, this meeting includes the works supervisor. If they don’t come to the
meeting, then at email is sent to the architect and the work supervisor and whoever the client deem
relevant is copied in that email.
Number 1.4
A call forward document or sheet is a document that shows all the orders that are being made on
site. It shows what and when the client ordered a given item, and what and when the supply was
made to the site. Call forward also shows why the material ordered was made, for instance the
client may order toilet for site use, it shows the date it was ordered, the date the toilet was delivered,
the name of the supplier and the instruction to the supplier or the contractor. This is an easy way
tracking the product supplied, the validity or quality, and the person who supplied.
Number 1.5
The final project cost gives the ultimate cost of the project since the project is now implemented
and handed over. There are changes that takes place during construction that are unforeseen, these
changes attract variation cost which is usually paid to the contractor. This cost helps the client
knows the ultimate cost, and it from here that they can calculate their profit margin, or if it was a
house for sale, the sale price of the houses.
Number 1.6

The size of the timber, the nature of the timber and type of wood that the timber is coming from.
Timber is usually rated per linear meter (LM) in the BQ.
Number 1.7
The detailed analysis is made on a final sheet. To track the payments and be able to know the
ultimate cost of the project, this shows a cashflow which is finally presented to the client to
evaluate their profit margins
Number 1.8
The sure way of securing site documents is building a temporary site office and in it build a shelve
or a cabinet for these documents to be stored in. The files can be categorised alphabetically and in
an order of priority. The developer can buy a scanner, so that these documents are scanned and
saved in a computer.
Number 1.9
The construction site needs to be secured and, in the specification, the style of security needs to be
spelt out clearly. There’s a need to have a wall built and a solid gate built, for security since where
surfers are many this already attracts a population, and when this happens, then the site is at risk of
being vandalism or theft.
Number 1.10
1. Claims
2. Variation
3. Visitor’s book
4. Call forward sheets
5. Material delivery book
6. Project site meeting minutes book
7. Site instructions book
8. Progress report
Task 3
Number 3.1
1. Bills of quantities
2. Contract documents
3. Project work program
4. Drawings
Number 3.2
This is done to reduce the expenses and increase the profit margin
Number 3.3
To establish the critical path, and to deliver the project in the appropriate time
Number 3.4

The operational energy, the building might be built with the best standards, but the use of the
building, like vibrations and other use of the building that are physical in nature, might lower or
maintains the expected life cycle.
Number 3.5
To guide you in future when you want to get involved in another project.
Number 3.6
Defects liability period is the period that begins after the project has been completed where the
contractor can carry out any repairs for free in case there is damage before ultimately handing over
the project to the client.
Number 3.7
Contract amendments document
Number 3.8
The person carrying out estimates can allow for contingency sum; this covers anything that might
be added even as a result of conditions imposed by the approval body
Number 3.9
Nominated sub-contractor and a supplier are the sub-contractors or suppliers that are still being
vetted on the basis of competitive pricing
Number 3.10
Slump test is carried out to determine the workability of concrete and to establish uniformity during
construction.
Number 3.11
The mixed concrete is poured in a mould, and the height recorded at the time, then immediately the
mould is taken off. The resultant concrete (which will not have the same form as previously in the
mould) will have its height measured and compared to that of the mould.
Number 3.12
Timber should be stored in a store, and made to lie horizontally on a platform for it not to get any
moisture. The place should be dry
Number 3.13
Take the money from the contingency sum or cancel the order and organize for a fresh quote if the
timber is not yet delivered.
Number 3.14
Lightweight construction is a construction involving a small scaled building like a small residential
house and heavy weight is for a big building a multi-storey building with big columns and beams,

these buildings have a high thermal mass. Their performances and the embodied energy
performances have a direct proportionality.
Number 3.15
1. Price/cost
2. Quality
3. Distance from the site to the material
4. Form of the material
Number 3.16
Liquidated damages are the compensation given to the injured party for any infringement that might
have been caused unknowingly. In terms of working that has since been stopped due to client’s
directive, might be costed as a liquidated cost.
Number 3.17
1. Going over the design and revising properly
2. Consulting widely
3. Evaluating properly the BoQ
4. Vetting the suppliers before engaging them, as some liquidated damages are brought by the
delay from the supplier’s team
Number 3.18
Cost of variance is derived from the estimated cost of the project and the actual cost.
