Part B
1. The calculations of the labour for installation of the metal panels are based on the
length of the fence installed. The labor charges are done as per the perimeter of the
fence.
2. The labor components of the project will be priced at the same rate. The project had
tendered, and adjustments on the original documents may lead to slowing down the
progress of the work, which would lead to delays (Moore, 2016).
3. The project has deployed labour services from sub-contractor in which the sub-
contractor supplied both skilled and unskilled labor to towards the project. The main
contractor would be in charge of the subcontractor who is contracted to supply labor
(Stiglitz, 2011)
4. The manufacture of sandstone capping was done through precast hence the risk of
delay was experienced should the manufactured failed to deliver the supplies on time.
This means the project was to be halted as the supplies of the sandstones capping
were yet to be made. The risks can be covered by keeping the suppliers informed on
the urgency of the delivery and conducting close supervision of the supplies to ensure
they are done on time as per the specified time schedules (Towey, 2012).

Part C
1. The benefit of estimating the cost of a task by separately costing the materials, labour
and plant required.
The quality and quantity of the materials which are required can be full and accurately
determined before the commencement of the project (Baron, 2017).
The delays are reduced. By having accurate quantities of materials, labour, and
equipment which are needed for the project to be completed it is much easier to set
dates when the project will commence and when it is expected to be complete.
It is much easier to administer the project by using the estimations. This is because the
client and the contractors are aware of what is expected from them by using the
resources which are listed in the quotation (Willis, 2015).
The quality of the overall project improves. Once the contractor who has been tasked
to execute the project has the overall view of what e/she requires to carry out the
project. He/she will now focus on how to construct a high-quality project.
It improves the flexibility of the project. Once the amount of labour, materials, and
plant which will be required for the project has been estimated there is always room
for adjustments during the construction process in that way the flexibility of the
project is increased (Bhavikatti, 2017).
It makes it easier to control (cost) finance of the project. All the quantity of the
materials and equipment required for the project are pre-determined to ensure that
enough money is set aside to cater for them all.
To eliminate sub-used labour and equipment maintenance.

CERTIFICATE IV IN CONSTRUCTION
Once the project has been subcontracted each subcontractor know how to deal with
his/. Her own labour which and equipment which in turn reduces the sub-using
different labour at different phases of the project.
2. List the considerations that would affect your decision on whether to tender on a
project or not.
 The time available for the project to be carried out. The time available greatly
determines whether the client can execute the project alone or he/she has to tender.
 The budget of the project. Which will determine if there are sufficient resources
for the project to be executed. The budget which the different binders present
during the biding has a great impact whether the client will render the project or
not.
 Availability of materials labour and equipment for the project to be completed.
 The type of the project to be constructed. The type of the project determines the
input regarding the materials, labour, and finance. The small projects are usually
administered by the client without necessary tendering out. But in cases of
massive projects, the client can opt to involve other parties to improve the quality
of the project.
 The span/size of the project which is to be constructed (Brook, 2012).
3. Factors which determine the size of plant needed to complete the task.
 The type of the project.
The type of the project affects the price. This is because the size of the project greatly
influences the exaction being done. For instance, in the cases where the project is
massive and has to have basements, it, therefore, requires deep excavations unlike the

9
CERTIFICATE IV IN CONSTRUCTION
small projects which require just strip foundation, and there are no basements
(Cornuejols, 2014).
 The amount of waste soil that has to be moved.
Where there is a lot of waste soils that are to be moved heavy plant are required which
can be able to carry out the task without any challenge (Xpress-MP, 2010).
 The size and depth of the excavation.
The size and depth of the hole to be excavated greatly influences the type of
equipment and machinery which is required to carry out the task (Fatzinger, 2014).
 The type of soil to be excavated.
If the soil in your at the site has particular characteristics that complicate the
excavation process, then the sophisticated equipment will be required to do the
excavation.

5. Why do engineering drawings take precedence over architectural drawings when
estimating and constructing a project?
The engineering drawings tend to be consistent in that the ideas are logically
presented, unlike the architectural drawings. Consistent methods allow several
estimators to complete various parts of the quantity survey, or be continued later by
another estimator (Hagan, 2011).
The uniformity of the engineering drawings enable the cost estimator to come up with
a system of estimating forms and procedures that exactly meet the requirements of the
project, and that is understood and accessible by other parties who are involved in the
project. The architectural drawing lacks that aspect of uniformity which makes it very
difficult in estimating the cost of the project (Rubenstein, 2016).
The engineering drawings, unlike the architectural drawings, allow an engineer to be
involved in coming up with a structure that will aid in researching and developing
alternative methods that will result in cost optimization.
The engineering drawings can be used for the verification process of the bill of
quantities which have been generated/ the architectural drawings cannot be used for
this purpose (III, 2014).
The engineering drawings in most cases are detailed and straightforward to
understand the speciation which is presented, unlike the architectural drawings which
in most cases presents ideas on how the spaces will be used without giving the clear
specifications which will be used.
6. Reasons for sub-contracting pr5ojkects to other parties during the construction
process.
 To improve flexibility

11
CERTIFICATE IV IN CONSTRUCTION
The flexibility of a company can be defined as the ability of the company to adopt to
the changes in the market. By subcontracting any given project the regarding the
labour and the finance (Inmon, 2014).
 To Increase Productivity
By subcontracting very specialized teams are involved in the project. The
subcontractors tend to start presenting larger productivity than when the main
company was to be involved alone (James F. Kurose, 2015).
 Improves the Product’s Quality
By involving specialized people in all the phases of the project, there are very high
chances that the overall project on completion will be of high quality unlike when
only one company was to be involved in the execution (Tütüncü, 2015).
 To eliminate sub-used labour and equipment maintenance.
Once the project has been subcontracted each subcontractor know how to deal with
his/. Her own labour which and equipment which in turn reduces the sub-using
different labour at different phases of the project (James, 2014).
 To ease the control of finances
Subcontracts are very fixed contracts. During the process of subcontracting all the
teams are required to present their bill of quantities to determine which of the
subcontractors can provide the services at the lower price at the same time the agreed
amount of money are never changed. The cost of supervision is also lowered by
subcontracting (Lippman, 2015).
 To reduce delays.
During the process of subcontracting all, he involved parties agree on the duration
which the contract should run. All the teams involve a lot of labour to ensure that the

12
CERTIFICATE IV IN CONSTRUCTION
task which they are assigned is done within the agreed deadlines. To avoid the
penalties which are well stated in the contract law (Turton, 2013).
7. Issues of obtaining quotations from specialist trades or companies with whom you
have no previous association and no direct knowledge of.
The specialist or the company is likely to increase unusual additions in the quantities
of materials. The unusual additions will result to the execution of the project being
very expensive. The quotations which are obtained can not be able to fully and
accurately represent the quantities of materials and work to be carried out (Lovell,
2015).
The obtained quotation cannot be able to be used properly for the administration of
the project because the contents of this quotation are not accurate. The quotation
cannot also be used to estimate the cost of the similar project in future. Also, the
specialist or the new company can take advantage to exploit and exaggerate the
charges which they usually charge to their clients.
8. On-costs associated with directly employed labour.
 Pension contributions
 Payroll tax.
 Commissions
 Piece rate wages.
 Direct labour salaries
9. Conditions of a contract which may produce a cost on the project and are included in
the bill of quantities (Moore, 2016).
 Penalties
 Price variations clauses
 Payment conditions

13
CERTIFICATE IV IN CONSTRUCTION
 Contract change conditions
 Validity considerations
10. How to calculate the labour cost to complete a task when you do not know the time
involved to carry out the work.
In the cases where one is not aware of the time which has been allocated for the project, it
is much better to look at the similar projects which have been done. The high level of
repeatability of different aspects of the project can allow one to estimate (Packer, 2016).
The project is divided into different aspects of work the cost per unit of he completed
project should be compared to the unit of work which you divided. The multiply the cost
per unit by the total number of units.
