The work procedure is described as follows:

5.2.1 PREPARATION

Temporary yard such as stockpile and fabrication yard for building work shall be prepared

within the site after soil improvement. Location and plan shall be considered to avoid traffic

and congestions during mobilization of materials, machines and obstruction to construction

during the course of different activities in the site.

It is necessary to set up a fabrication yard in order to carry out the fabrication of

Reinforcing bars, form work, steel frames and so on. And also, those fabricated ,cast,

assembled products will be temporarily stocked at the Stock yard. The yards will be graded

flat at the designated area and with adequate drainage.

Joint survey with the Engineer’s representative shall be carried out to establish control

points and confirm the coordinates and elevation prior to the commencement of the

construction works.

After confirming the coordinates and elevations of all the building location, survey location

for piling and excavation shall be carried out each stage of the works.

5.2.2 EARTH WORK

5.2.2.1 Excavation work :

Excavation shall be done in a safe and sequential manner on the basis of the prepared plan

drawings and in accordance with the instructions by the Engineer.

The excavation method is either machine or manual cut, and care is to be taken not to

disturb the soil below the supporting ground. If deep trenching needs shoring, proper lateral

sheeting and struts shall be provided for safety.

During excavation, drainage ditch shall be provided and sloping down to sump pit to

prevent flooding within the work area in case rain occurs. Earth excavation with sloped roof

and surface drainage to avoid scouring off part of excavation pit.

Unsuitable material and waste matters shall be removed from site to the waste yard in

accordance with the specification requirements.

After excavation, the bottom surface of pit shall be compacted to not less than 95% of

maximum dry density by vibratory plate compactor and the slope shall be trimmed off to

avoid collapse of pit wall.

Pile Driving

a) Driving lower segment pile .

Crane will lift up the lower segment pile. After lifting , the pile shall be held along leader

of diesel hammer

The pile position shall be adjusted by moving the leader. The hammer with the cap is then

mounted on the pile top. Before starting driving, the verticality and position of the pile is

carefully checked by total station and theodolite and adjusted as required.

b) Driving upper segment pile .

When the lower segment had been driven the second segment will be positioned

concentric to the bottom segment held up and aligned vertically.

Prior to splicing area to be jointed must be free from rust, oil, water and other foreign

matter that would affect the quality of the welded joints. Splices will be by butt type joint

using arc welding. All welded joints will be inspected visually .

Page 9



Driving will be stopped when bearing capacity is already achieved, through the application

of Hiley’ s formula in calculating the bearing capacity. See PDA Test calculation .

If it is found that the bearing capacity is insufficient against design after the rebound

record, the pile will be extended and re-driven until the bearing capacity is attained.

In case the pile tip can not reach the design level due to unforeseen hard layer, these matter

will be reported to Engineer.

If piles can not be driven to the design level but has already attained the required bearing,

the driving shall be stopped to avoid buckling or cracking in accordance with Specification

and Engineer Instruction.

Pile head treatment shall be done after getting the Engineers’ Approval.

5.2.3.3 Pile Record

Before final setting of the piles, the rebound shall be recorded.

The pile driving is deemed completed after confirmation of the sufficient bearing capacity

against design. Bearing capacity for all piles will be calculated with formulas .

5.2.3.4 Test Pile - (Test pile position refer to figure on page 9, pile driving)

Before piling, Pile Dynamic Analysis will be conducted to confirm the pile capacities and to

decide the correction factor of Hiley’s formula. PDA test provides more information, about

Skin resistance distribution, Toe resistance, simulated static load-settlement relationship,

pile integrity, stresses in the pile during the blow.

The detail procedure shall be submitted in separate document.

5.2.3.5 Quality Control

a)Inspection of pile .

Pile material such as concrete , rebar and wire strands or tendons ( for pre – stress type )

shall be inspected on factory before fabrication and the finished product shall be inspected

before delivery.

The inspection report shall be received before arrival of piles on site.

Upon arrival on site, piles shall be inspected as to dimensions, quantity, and physical

condition and reported to the Engineer.

Page 11

Prior to the welding, the grooved face and its adjacent areas shall be completely free from

oil, paint, oxides , water and all other foreign materials.

When two lengths of pile are jointed, the end plates shall bear even in all areas, The

welding must be carried out according to the manufacture’s instruction and must be

checked before driving resumes.

During driving, the pile head will be protected by helmet of cast steel or mild steel fitted
