Pre-construction activities.
OFE Construction will setup storage containers to store their material and put all required
equipments on site. First day on site, the contractor will require drawing of the site from the
Engineer and confirm the quantities. Pre-construction activities need to be carried out by the
Installation Contractor prior to the start of the main water channel installation. These activities
include finalising the water channel route, detailed design finalisation, mobilisation, notification of
entry to landowners, setting-up of water channel arear, establishing temporary works requirements,
setting-up, design of land drainage in agricultural areas and reinstatement works, construction of
temporary access roads and pre-environmental mitigation works, and agreeing with landowners any
special requirements prior to entry onto their properties.
Employees must wear the appropriate PPE at all times (A minimum of hard hat, hi-vis
vest/jacket and protective boots).
The site is already hoarded off; secure any areas with barricades if needed.
Conspicuous safety sign will be mounted with site rules, petroleum precautions and
details of protective equipment needed. Deep excavation signs should be displayed
where appropriate around the dig area.
The area of the excavation is to be cordoned off and clearly marked; no personnel are
to work within close proximity of the pit.
FIRST AID AND EMERGENCY
A first aid, fire point and emergency muster point will be arranged, with staff being
aware of existing equipment and procedures.
OFE Construction uses a Site Establishment Checklist before Starting Construction
It’s there to help we prepare the construction site.
Site Establishment Checklist
Site establishment includes things like:
Protection to floors and existing surfaces.
Safety signs and first aid equipment.
Designated areas for material deliveries and rubbish etc.
Site Establishment Checklist
1) NEIGHBOUR NOTIFICATION LETTERS
Inform wer neighbours of intended start date and site contact numbers.
Do this at least 2 weeks prior to starting on site.
2) FIRST AID EQUIPMENT

Ceiling Application
1. Use a tape measure to establish ceiling height; measure and mark the desired height in one corner
of the room.
2. Using a spirit level, water level or a laser level, transfer the height mark (as per previous step) to
all corners of the room.
3. Join the marks (as per previous step) using a chalk line.
4. Measure 38mm away from the wall for installation of first M-strip ceiling suspension bracket.
5. Mark at 400mm centres.
6. Install suspension brackets using 2 x Gyproc RhinoBoard Sharp Point Screws 35mm per suspension
bracket. Use the chalk line as a benchmark.
7. Measure and cut steel brandering to size and clip onto suspension brackets.
8. After installing the steel brandering, install ceiling insulation according to SANS 10400-XA for new
buildings.
9. Measure and cut RhinoBoard 6.4mm to size. Install the board and fasten using Gyproc RhinoBoard
Sharp Point Screws 25mm spaced at 150mm centres.
10. After installing the first board, measure and cut M-strip to size and install the next RhinoBoard.
Repeat this process until the entire ceiling is covered.
11. After boarding is complete, apply RhinoTape to all joints.
12. Apply Gyproc RhinoLite to all joints (pre-filling of joints) using a 150mm taping knife.
13. Apply RhinoLite to the entire surface using a 300mm steel trowel.
14. Leave the RhinoLite to set for a minimum of 40 minutes. Using a block brush lightly sprinkle
water onto the RhinoLite surface. Use a sponge rubber float, and float the entire surface.
15. Using a 300mm steel trowel, scrap off the dead plaster (fat).
Water Channel Construction
Activity 1.
The survey crew are the first personnel from the construction contractor’s workforce to
enter the site to commence the main construction activities. The setting out of the works should
be scheduled to commence at least 2 days prior to the remainder of the construction activity
group 1 activities. This work will be carried out with small four man crews using surveying
instruments. Setting-out pegs will be placed at all boundaries, changes in direction
and intermediate sightings on the proposed centre line and the extremities of the working
easement. Part of the setting-out crew’s duties is to identify any existing services that cross or are in
close proximity to the water channel and supervise the trial hole crew. The trial hole crew will hand
excavate to expose, identify and determine the exact location of all existing services. This data will
be recorded and transferred to the engineers for incorporation into the final water channel design.
Activity 2 – Remove Existing Water Channel
Step 1
Examine the area that is to be torn up. Put up construction works signs to inform the local
authorities. The size of the area will determine what tools are needed to do the job. If ripping out a
small section of water channel, we will need a pick-axe and a shovel.
Step 2
We will use shovels to load the removed water channels into wheel barrows and move away from
site to an approved area by local authorities. The area where new work needs to be carried out will
be cleaned and barricaded.
Removing Roof Trusses
Step 1: Remove the Existing Roof
The first step when removing a wood roof truss is to disassemble the existing roof that is causing a
load upon the truss. This can easily be accomplished by using a hammer and a crowbar. When taking
the roofing materials off be sure to extend the path of demolishing to each existing truss on each
side of the damaged one. This allows the load bearing truss to be relieved of all pressure, allowing
we to safely take it out.
Step 2: Remove the Wood Roof Truss
The second step is to remove the wood truss. Use the reciprocating saw to cut through the metal
brackets and lower the truss down to the ground. If the truss is large, we may need to rent a crane
to safely get the damaged material out of the way.
Painting
Step 1 - Protecting Landscaping
Before begining any work we’ll need to protect the landscape around the building. The cleaning and
painting process involves some harsh chemicals that can be detrimental to the health of some plants
and trees. Cover with plastic any brush or plants close to the parts of the building we will be planning
on painting. Using plastic will also help catch loose paint chips as we remove them, making clean up
a little easier.
Step 2 - Give the Surface a Good Cleaning
Paint adheres best when applied to a clean surface. Dirt, grime, mildew, and any other source of
debris can cause the paint job to appear uneven. The best way to properly clean a surface for
painting is to use a pressure washer with detergent. However, pressure washers can damage wood
and other surfaces if not used properly, so make sure we set the washer on an appropriate setting.
For parts of the building that are not flaking or extra dirty, a garden hose and brush will do just fine.
A common cleaner that many experts recommend is Trisodium phosphate (TSP) because it's easy to
use and safe for the environment. If wer exterior is stucco, then a thorough brushing with water is
normally all that is needed to clean the surface.
Step 3 - Remove Loose Paint
After the surface has been cleared of any dirt and debris, we will want to make sure any loose paint
is scraped away. Use a wire brush to take away any paint that is readily flaking or coming off the
building. Keep in mind that we don't need to remove all the paint down to the original wood.
Step 4 - Fill in Surface Imperfections
After all the old loose paint is gone, thoroughly examine the building for any cracks, nail head
depressions, and imperfections. Whether the surface is stucco or wood, the idea is to create as
smooth a surface as possible for the paint to appear uniform.
Step 5 - Give the Surface a Light Sanding
Now that the surface has been cleaned and any cracks or other imperfections are sealed up, it's time
to sand. A light sanding will knock down any high points in the siding and help ensure a uniform
surface. Again, the idea is to come away with the smoothest surface possible, so the amount of time
spent sanding will depend largely on the amount of putty and filler we used to clean up those
imperfections in the siding.
Step 6 - Apply a Coat of Primer
After all the surfaces that need painting are sanded down, the next step before we start painting is
to prime. A good coat of primer will ensure the first coat of paint adheres evenly throughout the
exterior surface. We will need to check the specifications provided in the BOQ with local paint
experts to help we decide which primer is best for the surface we're working with. After we have
applied a coat of primer, we're ready to paint.
Installation of New Water Channels.
Activity 1
Where the water channels is to be laid on an existing subgrade that is too low, the subgrade and
subbase shall be constructed in accordance with the requirements of SANS 1200 DM and SANS 1200
ME, respectively, and shall conform to the tolerance requirements.
We will check the levels of the earthworks conform to the specifications and drawings and where
necessary gets the contractor to take remedial action. Depressions shall be filled with material that
has the physical properties specified for subbase material in SANS 1200 ME, and the material shall
be compacted to 98% of modified AASHTO maximum density
PLACE PEGS TO MAINTAIN REQUIRED LEVEL
Activity 2 - EDGE RESTRAINTS
Edge restraints consisting of channels will be constructed before any units are laid. The function of
the edge restraint is to retain the sand bedding and to ensure that units at the edge of the water
channel do not creep outwards or rotate under load with consequent opening of joints and loss of
interlock.
Activity 3 – Putting Timber to align the water channel
We will put a length of timber the required distance from the paved surface (in this case, slightly
wider than the guttering used to mould the channel). Then hammer in wooden pegs at intervals and
nail them to the timber. The channel should run at right-angles to the fall of the paving. Use a one
metre-long straightedge and a 12.5mm shim to set a fall of 1 in 80 along the drainage channel.
Activity 4
Next, we will place precasted concrete water channel to the specified level in between the pegs and
timbers.
Activity 5
Press the guttering into the wet concrete to leave a clear imprint. After this, remove the guttering
and smooth any ridges in the concrete. Use a spirit level to make sure the fall is set at the correct
angle.
Site De-establishment
On completion of the project, the site will be cleaned, site will be handed back to the
client and the following will be removed from site:
Plant
Storage offices
Excess material
Jojo Tank (Water supply)
