Introduction
When construction is taking place, there are several stages the construction goes through for an effective
product being constructed to come out well. When a stage is skipped, losses can be incurred in terms of
time wastages to recover the left part, and waste of material, especially if demolition is involved. For the
various stages of construction, there must be a proper planning done by either the project manager, or the
architect, or even any stake holder of the project. The report herein, will show the stages from the time the
site is set up, or from the design stage of the project and design methods, through to planning the project,
where there shall be a presentation of calculations of the long the project shall take, determining the
program so that an overall programme for the whole project can be established.
The site needs to be prepared to take care of safety measures for protecting the persons who will work on
the site, those visiting the site and the environment where the construction will occur. The site
management needs to make sure that there’s a proper coordination to those who are supposed to deliver
tools, personnel and materials that shall be used on site. This stage of site set up should be done carefully
and not rushed, the construction manager needs to make the crucial decisions (Turnbull, 2017). Other
activities involved in site setup includes
Traffic management, ensuring the vehicles are not posing any danger to people,
Protection, which ensures that the people visiting the site are protected from hazards, protection also
could mean restricting entrance to site,
Storage facilities and dealing with wastes, the materials brought to site should be stored well because
others like cement are damaged when exposed in moisture.
Welfare, this involves meeting the local authorities and legal requirements, others are like providing
washrooms/toilets, safe water for drinking, changing rooms etc.
Administrative measures, which ensures that the site is approved to have met safety standards and the
standard operational procedures, like the paperwork etc (Health and Safety Executive, 2019).
A good site setup is necessary because it displays the professionalism in the parties involved to the public,
and the client. When the site is properly setup, issues to do with time management and organization are
tackled easily.
It is important to know what a method statement is in construction, since this paper widely uses methods
statements in analysing the work. A method statement as widely used in construction, which others refer
to it as a safe system work, is a document prepared to display or present the details involved in a project
and how they are to be completed (Murphy, 2016). Method statement include the hazards that are going to
be encountered and how to overcome them by explaining or listing a step by step methods of doing jobs
safely. There are control measures that are being introduced that guarantees safety of persons who might
be affected by the tasks or work being carried out. These details, in some construction works, must be
presented during tender period for evaluation of a company’s operation module and if a company is able
to undertake the job at hand (Designing Buildings Wiki, 2018). This paper shall look at design, tabulated,
and descriptive method statements.

The site mobilization is yet to begin at this
stage, there's signing of contracts and agreeing
on terms
2 2 2
Possession of the site/site hand-
over. General clearance of the site,
like removal of surface, materials
like stumps of trees, shrubs, extra
grass, removing the trees on site
location, rocks being carted away,
and just general unwanted materials
removal
1 day
This period needs to be taken seriously since
those foreign materials at the construction site
could be dangerous and could affect not only the
tempo of construction bu quality of construction
as well
3 3 3
Hoarding and general site
security. This involves the
construction of hoarding to
barricade the site and protect it from
foreign unwanted persons. Also
hoarding helps in the security,
people might come and steal the
materials or the tools that are used.
Employing a security personnel and
building them a house
1 day
This period could take a longer time than
expected since, it depends on the site soil
structure. Also the supply of materials might
take longer. It might require prior planning

Installation of site buildings. These
are building that shall be used
during the contract administration
period, they include: Store (where
materials and tools shall be stored),
site office(where official site matters
shall be handled, also this will be a
place for conducting meetings),
temporary toilets (these shall be
carried and just installed on site),
and a section set aside for
construction materials like sand and
ballast to be poured or kept.
5 days
Another back-up time shall be left for this time,
since things like toilets being brought to site
depends on when they will be delivered. The
cranes that shall be used as well
5 5 5
Levelling of the ground to pave
ways for people and vehicles so that
when materials are delivered on site,
there shall be minimal (if any)
accidents.
1 day This also could take longer, maybe two days,
since it depends on the weather condition
6 6 6
Supply of Electricity and water to
the site. There shall be massive use
of electricity and water on site.
Especially water, shall be used to
mix the concrete for construction of
the sub and super structure of the
building. Electricity on the other
hand, shall be used for glazing,
grinding and welding of metal
works, light and power at the office
etc.
1 day
This should work well within schedule, since
the electricity is taken from an existing building
and not supplied by the authority

Calculations
Volume of work = 125.7m
Unit price = £16.74 each but the height and the width are @ 1.5m by 2.5m high
125.7m/1.2m=105 units used for hoarding shall be required
We shall determine the units required by the unit price, which is
105 X 16.74 = £1757.7 including VAT
Excavation volume calculation for the base of welfare
These data are obtained from (Excavation quantities and bulking factors., 2003)

15CONSTRUCTION METHODS AND TECHNOLOGY
Since the ground there has clay soil, the bulking factor is 1.4
24 X 3.4m X 0.5 = 40.8m3
40.8 X 1.4 = 57.12m3
