Introduction
The Oran Park is a housing development project initiated in the south west of Sydney in the
Marcathur area in the newly created south wales Australia. Initially, the area was a home to one
Murigong where he used to rear his Merino sheep (Maddox, 2018). The Oran park development
project was initiated to replace the Oran raceway which stood the test of time and has been here
since 1962 to 2010 until it was replaced with this promising development plan . The Oran park has
been a beehive of activities from being the commercial area of the region housing the Oran park
podium which stores goods and services to be used by the members of the community. The park
also houses a housing scheme which is used by the members f the community to set up affordable
rental services in the region. The area has seen an improvement in population density. According to
the 2016 census, the area has a population of about 4765 residents(Willis, 2010). The region has a
mix of native Australians and a mix of some Spanish speaking communities who leave in harmony.
The area is under the jurisdiction of the Camden council and managed by the Camden mayor.
When our group visits the Park for a grand tour of the facilities, we realized that their swimming
pools were not to the standards of the Olympic, and there were hardly any swimming pools except
in the expensive hotels and motels of the park. With the growing population of the working class
around the park, we felt the people deserve a standard swimming pool to enhance recreation and
fitness that will intern enhance their productivity in their workplaces. The pool will also be a form
of enhancing fitness and physical therapy which is a preventive measure to thwart future illness,
swimming pool provides perhaps the best form of exercise for our body by enhancing metabolic
activities in the body. The pool will also serve as an entertainment spot for the people around the
park as it can be used to host swimming competitions from an Olympic perspective. The above
reasons prompted the group to come up with a report detailing how we are going to achieve the
construction of the Olympic size pool centralising our report from construction perspective, the
various ground works and earthwork needed, the tools we envision to use, the machinery that will
help us achieve the objectives, various safety measure and environmental concerns that we shall put

into consideration when making the plan. The excavation and the construction methods to be used,
the cost estimations among others. The report shall be vital for the final implementation of the
project(Oran Park Town Art and Craft Markets | Sydney, Australia - Official Travel &
Accommodation Website, 2018).
WHS (Work, Health, and Safety) Issues
The International Labour Organization (ILO) established the code of safety regulation in the
industrial establishments in 1949 whose aim was to set up good practice and standards that could be
followed global and install practices where one does not exist. Acquisition of tools and machinery
should ensure they conform to the ILO regulation so that their operations are safe. This shall be the
first issue we shall deal with when procuring the earthwork machinery we shall use. Most safety
concerns arise from non-coordination of most of the critical tasks in the construction sites, This has
caused a lot of injuries to some coworkers who are not in sync with each other on their
operations(Behm, 2005). The group shall divide the work according to specialty and assign the most
qualified individual in that field to lead the team. Thi shall reduce the risks associated with lack of
proper coordination among the coworkers when we shall be implementing the construction. Another
great risk associated with handling the machinery are the defects associated with some of the
machinery. This defects if not identified earlier and corrective measures taken to reduce the threat
materializing. The group has assigned the quality assurance team to ensure all the construction
equipment are standardized and that their defects are detected earlier and a corrective plan in place
to mitigate such risks. The construction site will be off-limits for minors as they may pose serious
risks if allowed near the machinery. The group shall use signposts signals to deter any minor from
accessing the swimming pool while under construction and even during its opera the management
of the pool shall take due diligence to deter minors from accessing the pool without the guidance of
an adult. This shall enhance the safety of the minors in the pool vicinity. Another critical safety
issue in the management of wastes from the construction site. Such wastes as used scrap metals and
other metallic substances if not properly disposed of can not only cause serious injuries to the

general public but also cause a serious environmental degradation since most of them are non-
biodegradable. The group shall implement a cycle a waste management policy derived from the
ILO standards to ensure the environment, safety, and health hazards are reduced to a minimum.
All these safety regulations shall regulations shall be in compliance with the government
construction act of 2006 which requires all the players in the construction industry must
adhere to the requirements of providing safe spaces during and after the completion of the
various groundbreaking projects(Dingsdag, Sheahan and Biggs, 2006).
Major earthwork machinery and handheld devices
The groundbreaking machinery we shall use in the proposed project is outlined as follows,
1) Excavators
Escavator shall be used to lift heavy machinery that the group shall be utilized to complete
the earthwork to be done. This is due to their long bucket arms like structure which they
use to lift long objects(Miyaoka and Yano, 1999).
2) Backhoe Loaders
This machinery which to many looks like a tractor but in reality has some difference with
the conventional tractors. The shovel embedded at the back and front shall be used to dig
the ground for constructing the swimming pool. Our choice for this machinery is its ability
to be used in physically restrained areas while still
3) Bulldozer
Bulldozers are perhaps the most known machinery in the market as it is known for its
heavy-duty ready made. This will be used to shift a large amount of dirt from the dugged
ground for laying the foundation of the swimming pool (Harold, 1941)
4) Skid Steer Loaders
This machinery is particularly best for small sites like the proposed swimming pool. It is
relatively very easy to use and being on the wheels it has quick turning range.

excavations and method of construction
The swimming pool groundbreaking requires a special type of excavation know the earth
excavation whose details and operations is detailed hereinafter.
Earth Excavation Methodology
This method of excavation starts with the survey of the soil to be excavated, how the
machines shall access the site, the environment around the swimming pool. The process we
shall follow is as outlined below,

Excavation and Construction Process
The excavation will be preceded by ensuring the area of the park where the pool is to be constructed
is properly cleared of any vegetation and trees. This will be followed by a thorough landscaping of
the area. On the day of the actual excavation, the machines shall be transported to the site. The
bulldozer shall be used to to remove the upper top soil quickly. This activity usually lead to heaps of
topsoil. This shall be collected by the bulldozer in a pile so as to be tied again on top of the back fill.
Some of this dirt shall be used fill the spaces around the walls of the pool.
The vinyl method of excavation adopted for this pool will ensure the digging is in two parts, the
first step will involve over digging the one side unto approximately 24-30 inches larger than the to
be completed size of the pool. The walls shall be 42 inches long, so literally their will be 42 holes
which are 2 feet wider than but of the same shape as the to be finished pool.
The second phase phase will be to dig the deeper end of the pool. The outline of the vinyl is
outlined by a maker and be used as a guide for the operator of the bulldozer. This part nature of the
deep end will require a little digging around the corners to ensure they are firm.
Installation of the wall
Wall installation is a critical part of the pool construction, since it enhances the structural integrity
of the pool. Once the overseeing the various ares where the wall will be tied to, the panels of the
wall will be connected to each other using bolts and some kicker legs. Once the assembling is done,
we will use a transit to ensure the pool is leveled on all its corner sand that the bolts are tightened.
Once the the tightening is done, the concrete will be dumped along the pool edges. Our team shall
level I through the base of the pool to a depth of 10inches fill the areas which were overdue.
Installation of Floor
Based on the the nature of the soil, elevation of the site and the budgetary constraints, we settled to
use a poured concrete floor, which shall be done on the same day as the day we shall lay foundation.

We shall pour the concrete on a 6*8 inch pad which shall be placed on the deep bottom of the floor
and we shall use the verniculite for the shallow ends of the pool. All the three types of liner floor
material which shall be made of vinyl shall be spread up to a depth of 1-3 inches in thickness. This
shall be a one day operation.
Plumbing and Electrical
Plumbing step in the pool construction is vital to ensure smooth inlet and outlet of water into and
out of the pool respectively. We shall dig a trench from where the pumping system is based and the
filter all the way to the pool. We shall then connect PVC pipes which will be laid in the dug
trenches and connect using glue. The pipes shall connect to the pool via the main drain system in
the deep end floor. The other end of the pipes shall have valves to control the flow of water in and
out of the pool.
The electrician shall using the dug trenches to lay their conduits before the earth workers back fill .
The electrical current shall majorly be used to power the underground lighting subsystem. The
lights niches shall be placed strategically on the wall mainly in the deep end
Back fill your Pool Walls
The surface soil or material dirt is settled up against the walls of the pool, and compress every foot
of depth. Then, it should be watered very generously, to help the dirt settle down even more. On top
of the soil is ordinarily placed 3-4 inches of blue stone gravel, in the areas where you will plan to
have a pool platform installed. (WORK PROCEDURE - EXCAVATION, 2018).
temporary or permanent retaining structures and services associated with the earthworks
The excavation process shall incorporate some temporary structures that shall enable us to
undertake the excavation process, this includes,

The temporary fence around the proposed swimming pool working area thing is particularly
important to keep would-be intruders at bay from the working space. This is a security concern for
us. In addition, it will help us reduce vandalism of the various equipment and machinery we
proposed to use
Ladder and Temporary Stairway, The ladder and temporary stairway shall be used by our
workers to enhance movement to and from the dug swimming poll. This reduces the risk of falling
over into the dip which could cause death, the ladder used here are temporary.
Estimation of quantities and possible costs of earthwork and other calculations
Several calculations and estimation methods have been used in the proposed earthwork of the pool,
they are explained below
Measuring Earthwork Volume: We have used the depth area method to estimate the earthwork
volume, the algorithm is illustrated below;
V =T ∗ A ∗ (1 27 )
Where
V=Volume in cubic yards
A=Surficial slope area
T=Thickness of strata. (Slattery, Slattery and Peterson, 2011)
The above method measure the volume by multiplying the surface area of the site and the thickness of
the earthwork
Circular Pipe, Rock Foundation
This is a measure of the quantity that the earth foundation requires plus the foundation's backfill below
the pipe. The algorithm is defined below;
W =2W + B −2 A /12 (Houlsby, 1990)
