ODFJELL WORKSHOP AT KEMAMAN SUPPLY BASE PHASE 2
Introduction
Odfjell Well Services Ltd is one of the oilfield service sector company in Malaysia.
They propose to build workshop at Kemaman Supply Base (KSB) Phase 2. Salendi Engineering

A. EXCAVATION
Excavation is one of the important part in construction. In this project, we used backhoe to
excavate the ground for concrete floor, electrical work (armoured cable), and cold water
plumbing.
1.0 CONCRETE
In this section, we will excavate the soil by following the standard specification of Jabatan
Kerja Raya (JKR) Malaysia. Excavate area will mark first as per drawing. The standard
thickness of concrete is 200mm. So the depth to excavate is 250mm. Picture 1 below show the
process of excavate at site.

1.1 Formwork
Formwork is temporary or permanent molds into which concrete or similar
materials are poured. After excavate work done, we will prepare the formwork. Usually,
the formwork use is wood. Picture 2 below show the example of formwork.

1.2 Install BRC Reinforcement
Reinforcement within concrete creates a composite material, with the concrete
providing strength against compressive stress while the reinforcement provides strength
against tensile stress.
In this case, we use BRC wire mesh as reinforcement rather than rebar because
there is less bending and sorting of the bars. This means less workers needed and save
space for storing and working the steel. The standard specification of BRC we will use
is A10 type with diameter of wire is 10mm. the BRC wire mesh will be arrange in the
concrete area. Picture 3 below show the example of BRC wire mesh.

1.3 Pouring Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded
together with a fluid cement (cement paste) that hardens (cures) over time. In this
project, we will use concrete grade 35 which is standard specification from Jabatan
Kerja Raya (JKR) Malaysia.
The concrete will be order from BABENA mix industries Sdn. Bhd. Concrete
then pour into BRC until reach the standard thickness around 200mm. Picture 5 below
show the pouring process of concrete.

1.4 Leveling
In civil engineering, concrete leveling is a procedure that attempts to correct an
uneven concrete surface by altering the foundation that the surface sits upon. We will
do the leveling process after pouring process.
Conclusion is this concrete with BRC reinforcement by following the Jabatan
Kerja Raya (JKR) Malaysia specification, the weight rating is 980 kg/m2 and the max
load concrete can support is 20 tonne.

2.0 WATER PLUMBING
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses
pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.
In this section, we need to excavate soil to place underground pipe from water supply to
wash bay section. This plumbing work we will do right before the BRC installation. The type
of pipe we propose is PVC. Picture 7 below show the process of plumbing work.
Picture 7: Plumbing work
3.0 UNDERGROUND CABLE
An underground cable is a cable that is buried below the ground. Also known as armoured
cable. For this workshop, we will use underground cable to connect from main distribution
board (DB) to wash bay distribution board (DB).
In this section, we need to excavate soil to lay underground cable from main distribution
board (DB) to wash bay distribution board (DB). This laying work we will do right before the
BRC installation. The types of cable we propose are 4C x 16mm PVC/SWA/PVC cable & 3C
x 25mm PVC/SWA/PVC cable. Picture 7 below show the process of cable laying work.

4.0 FENCING WORK
4.1 Dismantle
In this section, the fence pole and chain link will be dismantle. The chain link will be
replace by metal deck The beam will be repair. Picture 9 below show the process of
dismantle pole.

Picture 10: chain link fence dismantle process
4.2 Install metal deck
The last part is to install metal deck. The size of metal deck we will use is 20’ x 4’
Picture 11 below show the example of metal deck fence.

Summary
This proposal are summarized below.
1. Concrete type: Grade 35
2. Reinforcement material: BRC A10 with diameter wire 10mm
3. Concrete thickness: 200mm
4. Load support: up till 20 Tons
5. Weight rating: 980 kg/m2
6. Concrete use is approved concrete material from Malaysia Civil Engineering
7. The end product will be given 1 year warranty for any damage
