    • To distribute the drawings to the engineers who are supposed to perform to work with the drawings.
    • To run a blue print machine and copy machine to make sure that all the latest revision drawings and specifications to be distributed to the engineers or supervisors promptly in sufficient quantities to enable them o perform the work
  • Upon distribution of new issues of drawings, all previous will be removed from the active files and stamped “VOID”
  • The drawings and specifications receiving log sheet will be in-corporate in order that the every issue of the drawing and specification can be logged in.

Drawing and specification change notices will be logged in the D.C.N and S.C.N log sheet

The above mentioned revisions and/ or notices will also be remarked on the drawing distribution sheet to assure that every information essential for the engineer to perform the work in accordance of the contract drawings and specification is distributes to the Engineer.

Drawing Submittal

All the shop drawings and as-built drawings shall be prepared by ASC to be submitted to the Consulting Engineer for review and approval and will be controlled as follows:

Drawing Control:

Progress status will be reported to the project manager regularly by the periodically updated drawing control.

Drawings done by the Auto Cad operator will be checked by the concerned Engineer and the designed Engineer will do the final check prior to issuing them.

Drawing Submittal:

Drawings checked and approved by the Design Engineer will then be transmitted to the consultant with the corresponding submittal form.

Periodic Auditing by the Chief Inspection Engineer:

On the last date of each month, the project Manager will check whether only the latest construction drawing, specification are incorporated in to the work and also whether the Drawing and/ or specification change notice is rightly distributed to all whom it may concern. The auditing will be executed by the Quality Control Engineer with the information listed on the Drawing Control sheet and drawing distribution sheet

PROCUREMENT AND MANUFACTURING CONTROL

Overall description of the control over the procurement and manufacturing activities is described by head office procedures.

Control Manufacturing

Inspection:

Inspection will be carried out at the vendor’s shop or at manufacture’s factory to accomplish the following

  • To assure that the materials or the equipment is manufactured in the same design, dimensions and quality as specified approved by the engineer
  • To minimize the delays and loss prevention on the job site

Inspector assigned by the Project Manager will perform the inspection of the materials and equipment on fabrication at the factory or on the way of transportation according to the specification or the standards prepared by the Project Field Engineer.

The inspector will report the result of inspection and if necessary a joint inspection with the Engineer will be performed.

Final inspection will be performed by the inspector and expeditor prior to complete packing and assure the all the materials and components are properly consolidated without nay defect or default

Expeditor:
  • The stock and raw materials delivery schedule
  • The capacity and the condition of the work shop and factory
  • Manpower status assigned to the way of recovery
  • Review the fabrication process and delivery schedule
  • Elements of delay and the way of recovery
  • Assistance to the vendor in cooperation with the site
  • Estimation of productivity per day

On the materials or the equipment are manufactured, the expeditors at the port of origin and arrival will prepare the expediting report and send information to the Procurement Manager for forecasting and shipment tracking.

Receiving Control

Ware house man upon arrival of the material at the site will:

  • Check the shipment against the packing list, freight bill of lading, condition, identification, and conformance with the technical requirement.
