1. GENERAL

For the inspection and examination of all works including the works of the Subcontractors to ensure compliance with the specifications and drawings as to the materials, workmanship, construction and efficiency of performance, a complete QUALITY ASSSURANCE / QUALITY CONTROL system will be implemented with the team throughout the whole period of the contract.

 The system will allow the team to control all aspects of the implementation of the contract, such as:

 2. SHOP DRAWING PREPARATION AND MATERIALS SELECTION

A.  Monitoring of Documents.

 Our technical Department will monitor and coordinate all the detailed design stages of the Project. This applies to shop drawing preparation, materials, and equipment submittals and/or any special process submittals.

This monitoring will be carried out by the way of computerized listings, such as:

These lists will be updated on a weekly basis and issued to all parties (the Client and the Subcontractors) at regular intervals after having been check.

The computer list will indicate the identification number of the document, the revision index (if any), the originator of the document, the dates of submittal/approval and the status of the approval.

 

The status of the approval of the Client will be one of the following:

  1.   Approval as submitted.

  2.  Approval except as noted on drawings, resubmission not required.

  3.  Approval except as noted on drawings, resubmission is required.

  4.  Disapproved.

 

B. Preparation of Shop Drawings

The Design Section and Coordination Engineers of Technical Department will monitor and supervise the quality of the production of shop drawings so that:

The Design Section and Coordination Engineers of Technical Department will review the shop drawings as submitted by the Subcontractors and will issue, if required, to the originator the list of the comments using a "Technical Document Checking" (TDC) form.

Shop drawings will only be submitted to Client for approval once the above checking has been carried out. In addition, a stamp will be affixed to the drawings.

C. Interface Control

Interface control will be one of the main concerns of the Design Section and Coordination Engineers of Technical Department.

Interface between architectural/structural and electrical/mechanical items, as well as between the construction items and the equipment, will be identified in a "Room Schedule" indicating all items contained in a room.

Regular interface meetings will be organized with the Procurement Department and the Subcontractors/suppliers involved.

All interface information will be transmitted to Client for information and, where necessary, for further evaluation, review and/or approval.

3. CONTROL OF CONSTRUCTION OPERATIONS

The quality controls to be implemented during the construction and erection activities are of three different kinds:

 A. On-going Visual Inspection

Workmanship, materials, work process and finishing will be continuously controlled by the Site Engineers in line with pre-established checklists which includes:

              Preliminary Inspection   – before actual start of works.

                Follow-up Inspection     - during the course of works.

                Completion Inspection  - where the piece of work is completed.

Submit checklist forms, each checklist after being checked by Main Contractor Engineers, should be submitted to Consultant for his checking and approval.

The remarks and result of those inspection will be recorded in checklists, which include items on geometrical dimensions and levels of workmanship, compliance with approved drawings and with approved materials submittals.

As sample of inspection checklist for structural works is attached.

Those checklist will be dispatched to the Site Quality Control Engineer immediately after inspection for information and corrective actions, if required.

All the checklists will be filed in a booklet so that they can be reviewed at any time.

 

B. Covering Procedures

 Covering Procedures include covering inspections, concrete pouring inspection and setting-out inspection.

 

1. Covering Inspection:

The Inspection will be requested by the Site Engineer for any Construction activities, which will permanently cover other pieces of works.

 Those activities are as follows (not limited to):

As form (refer to attached sample from) will be issued by the site staff and signed by Quality Control Engineer and Client for release of further works.

 2. Concrete Pouring Inspection:

 Before each pouring, a Concrete Pouring Inspection form/slip will be issued to Client. Each item of the checklist should be filled and signed by the Inspector, Site Engineer and the Quality Control Engineer.

Sample of form is given. 

Pouring will not be allowed without the approval of the client's site representative.

 In case of precast panel or structural elements, special concrete pouring inspections forms will be prepared.

 3. Setting-out Inspection:

 Before starting the construction of the foundation of a building, a combined survey will be conducted by both Survey Team and Client's Surveyor. During this inspection, layout and levels are checked against approved drawings.

An inspection Form will be issued and signed by both survey team representatives.

 C. Laboratory and In-Site Tests 

  1. Laboratory and in-situ test will be performed according to specified standard and procedure  mentioned in the contract specification from which specifies the number of tests and code of standards required.

  2. Sample list of laboratory and in-situ test in attached for control purposes.

  3. Detailed list of laboratory and in-situ test will be prepared according to the requirements of contract specifications. These listing indicate the type of test and frequency required, to be strictly followed by the Quality Control Engineer.

 

4. PERFORMANCE CONTROL

A. The Steps of Performance Quality Control

  1. Materials / Equipment Arrival at Site – all type of material and equipment with a copy of shipping documents will be presented on the same day for checking against contract requirements and for may any damage in handing.

  2. before installing an individual piece of item , it shall be checked and inspected first against specified manufacturer’s technical data and with the corresponding contract technical specification.

  3. once this procedure have been done , the result will be submitted to the client for his approval and go signal to proceed with the final installation .

 

B. Testing Individual items

 

Once installed, each individual piece of equipment will be tested in accordance with contract specifications.

 

The following kinds of test will be carried out;

•  Visual Testing (inspection)

 The aim is to verify if the equipment is visually in order ; no apparent damage , installation is sound ,all external parts are fastened to the machines, interface with other equipment are in order , identification label is complete and visible…

 

A checklist for each type of equipment will report this visual testing . manufacturer test certificates, where available will be attached with the inspection request to client site engineer.

 • Equipment Testing

 Each piece of equipment that can be isolated will be tested against its individual performance requirements.

 This includes; motor, air handling units, cooling plants, fans,……

 A testing procedure and a form to summarize the results of the tests will be prepared for each equipment and sent for client's approval

 • Construction Test;
