MATERIAL RECEIVING INSPECTION a)

U p o n a r r i v a l o f t h e m a t e r i a l a t f a b ri c a t i o n y a r d s , W a r e h o u s e S e c t i o n w i l l inform QA-QC Department and Project Control to recheck the raw material. Scope of the inspection shall include visual dimension, sharpness, thickness, heat no. or manufacturer no., etc.

b)

Identification marks of material grade shall be clearly marked on all pieces of material including those cut from stock or from the whole material itself. This

identification

marks

shall

r e m ai n

clearly

visible

at

all

times.

Recommended type of medium for identification marking shall be stamp, paint or crayons. Subcontractor shall propose to Contractor the method inspection. c)

Any non-conformance between Client document and material received by PT. ………………,

QA/QC

Department

will

inform

with

Quality

Assurance

Confirmation (QAC). d)

When

some

material

are

unacceptable,

QA/QC

Department

marked

Inspection result shall be reported in Material Receiving Report .

MATERIAL CONTROL a)

After material received inspection has been conducted and material been accepted, the Warehouse Section shall store the material and issue to the fabrication section upon instruction.

b)

The

material

received

by

Warehouse

Section

and

material

issue

for

fabrication shall be continuously reported to Project Control of status the Project’s materials. c)

The

excess

raw

material

from

the

fabrication

section

shall

clearly

be

identified and returned to the Warehouse Section for restore. d)

Stock material on warehouse shall be checked for visual and Dimension by quality control. Material should be store in secure place to preserve the accuracy and quality before process fabrication.

QUALITY CONTROL INSPECTION PROGRAMS FOR FABRICATION A l l f a b r i c a t e d p a r t s h a l l b e i ns p e c t e d t o t h e f o l l o w i n g i t e m s : 7.1. IDENTIFICATION MARKS a) Transfer of identification marks (include heat no.) shall be check prior to cutting. b) Material traceability report shall be made. 7.2. MARKING a) Giving the mark OK, if result of mark is correct. b) After giving mark OK, we can do the next process. 7.3. DIMENSION a)

Checking the “ MAL “ according on the place.

b)

MAL

made

the

duplicated

equipment

as

same

as

one

from

paper/plywood. c)

Identity that the MAL has been made and checked in accordance to drawing approval.

d)

Only approved MAL will be used for fabrication process (marking, cutting, bending, rolling, beveling)

e)

Progressive

dimensional

check

shall

be

conducted

at

stages

before, during and after the manufacturing process. f)

Dimensional

marking

shall

be

c h e ck e d

prior

to

cutting,

beveling,

bending, and rolling. After part or final assembling, all dimensional marks are to be reconfirmed for accuracy prior to further works such as reforming, etc. in which the dimensional inspection shall be conducted. g)

All measuring Tools to be used for Measuring and Inspections shall be calibrated by an Authorized Agency. The Calibration records shall be kept as a QA records.

h)

Check with measuring tools all dimensional of individual members/shop assemblies, within the specified tolerance.

i)

Inspection result shall be reported in the from of Dimension Inspection Report (Attachment – 2)
