KEMENA INDUSTRIES SDN BHD

REINFORCED CONCRETE SQUARE PILE

Product Specification

Certified to ISO 9001:2008 Cert No. AR3901

COMPANY PROFILE

KEMENA INDUSTRIES SDN BHD (KISB) was incorporated on

17 March 1987. It was jointly formed by IJM Corporation Bhd

(IJM) and Bintulu Development Authority (BDA). IJM is one of

the Malaysia’s leading conglomerates and is listed on the

main market of Bursa Malaysia Securities Berhad, whereas

BDA is the local government authority.

Since its inception in 1987, KISB had started to manufacture

varies sizes and lengths of R.C. Square Pile. Over the years,

KISB has expanded its business activities and improved its

qualities of production to meet customers’ expectation. The

production operations are carried out and supervised by

experienced staff. KISB’s quality control system was awarded

the prestigious ISO 9001:2008 for the manufacturing of

precast concrete products and ready mixed concrete.

INTRODUCTION

The aim of pile design is to provide a footing which will safely

support the superstructure over its design life. The footing

shall be durable, and of adequate strength and the footing

performance shall be compatible with the superstructure so

that it remains serviceable and can perform its intended

function.

Piles are considered of displacement type and they shall be

designed for both structural and geotechnical strength

requirements. Once the piles are driven to their final position,

the stresses caused by foundation loading are likely to be

much lower than those caused by handling and driving.

The reinforcement requirements are predominantly catered

for handing during manufacture, storage, transport and on

site as appropriate.

SPECIFICATION AND DESIGN

Piles shall be designed to BS 8110 or CP 116 and to MS 1314.

APPLICATION

Civil Engineering and building structures on land or

immediate inshore locations intended for use as permanent

structures.

MANUFACTURE

Steel moulds are used to manufacture the piles in a factory-

controlled environment. After the concrete has been placed,

vibrated by internal vibrators and cured to sufficient strength,

the products are demoulded and the production cycle is

repeated.

CONCRETE MATERIAL

AGGREGATE

Coarse aggregates and fine aggregates shall comply with MS

29.

ADMIXTURES

Admixtures when used shall comply with MS 922. Calcium

choride or admixture based on calcium choride shall not be

used.

CEMENT

Cement shall comply with MS 522.

CONCRETE

The concrete grade shall be 45 N/mm2.

REINFORCEMENT

Reinforcing steel shall comply with MS 146 for main

longitudinal bar and MS 144 for the lateral links.

JOINTS

In lengthening of piles, the mild steel and plates are butt

(blunt point), jointed centrally and axially and subjected to

field full penetration butt welding.

LIFTING AND STORAGE ARRANGEMENTS

Pile shall be lifted at the designated lifting points provided

along the pile. All units shall be stored on an unyielding

ground and stacked with timber.

SURFACE FINISH

Small blemishes caused by entrapped air or water may be

expected but the surface shall be free from voids, honey

combing or other large blemishes.

QUALITY ASSURANCE

Quality Assurance in the manufacture of the products is

provided by established MS ISO 9001 Quality Management

System.

Note:

1. The axial load capacity represents the structural capacity of the pile. Soil condition must be considered when determining

the safe working load of the pile for a particular site. However, the actual working capacity shall not exceed the

recommended axial load capacity.

FORMULA FOR AXIAL LOAD

The axial working load (Safe Working Load) of the pile is calculated in accordance with BS 8004, BS 8110 and CP 116.

According to BS 8110-1:1997, Clause 3.8.1.1,

Recommended axial working load = 0.25 × fcu × Ac

fcu = Characteristic cube strength of concrete at 28 days = 45 N/mm2

Ac = Area of concrete
