Projects Team and senior management are committed to providing a project that meets EMPLOYER’s objectives as well as our own principal objectives. We take pride in our work and are confident these will be accomplished. The principle objectives that the C.A.T. management expects to be met are as follows: − Meet all critical milestones and complete the Project on schedule

(4)

Q06024-IDCP-PLN-GT-001-REV A - 4 - − Maintain project costs within budget − Meet technical performance objectives − Obtain total satisfaction from EMPLOYER The proposed Project Chart (see Appendix 1) has been developed to achieve the above mentioned expectations. The successful management of the project requires good communications between the engineering team and construction team, comprehensive management information systems and a competent, well‐directed project team.

Directly upon award, a qualified management and supervisory Project Team was appointed to prepare a detailed study of the project requirements as far as engineering, materials, equipment and labor force required (see Appendix 2, Contractor Organization Chart). This group of dedicated project personnel began identifying the priorities to be completed in the early stages of the project and planned for the initial “kick‐off” meeting that was held in QC offices. This initial meeting was important in establishing a strong team relationship with the QC, DAR & SCI. After award of the contract, the management personnel from areas began mobilizing to fulfill the staffing needed for the project .This staff started with SCI verifying the available design. Based on the concept design, procurement of the LLI Long lead items (see list in Appendix 3) started as per the procurement procedures. The project key mile stones (see Appendix 4) were to be confirmed as per the suppliers & project progress. SCI started with the concept design, aiming to submit the same to QC & DAR for clearance and to go ahead with the detailed design.

Q06024-IDCP-PLN-GT-001-REV A - 6 - The requisition of LLI is critical and will be developed on a rush basis, immediately after contract award and approval of concept design. Owning to the critical milestones requirements, it is essential that acceleration “premiums” for specific equipment and materials to be developed and reflected C.A.T.’s flow procurement activities, as shown above, include the following polices: ‐ A well‐screened project vendor list with a preference for QC recommended vendors will be prepared , reflecting C.A.T. recent procurement experience; due consideration is given not only to technical capabilities , commercial competitiveness and offered guarantee conditions, but also to delivery performance. ‐ Purchase order placement will be based on quotation development except where source or lead time constraints dictate otherwise. ‐ Fast‐ tracking procedures are established to facilitate early procurement of long lead time items; closely‐knit inter facing among QC, DAR, C.A.T. and SCI is expected and will be implemented. ‐ Rigorous expediting and frequent tracking of materials status will be performed in the realization that any delay from the Construction Required Dates (CRD) of materials arrival on the site will endanger meeting of the contractual project completion date. ‐ An efficient field materials control system will be established and through indoctrination on warehousing operation will be carried out. LLI procurement will be done as per our C.A.T. standard procurement procedure, in order to comply with the employer specified policies. 3rd_{Party Validation (if required) for LLI procedure} will be performed as and when required. As part of procurement activity C.A.T. & SCI will carry out a technical evaluation for each item starting with technical clarification and finalizing with a Technical Evaluation Report C.A.T. & SCI will carry out also a review of vendors drawings / documentation as part of the above mentioned procurement activity.

The technical bid evaluation will be undertaken by each engineering discipline. The technical bid evaluation is used to summarize the technical aspects of bids received for a specific requisition, in order that the bids may be compared and evaluated. Proposals (bids) are forwarded to the SCI Engineers and CAT Construction Managers for evaluation.

A thorough review of technical data will be made to determine whether bids conform to the specified technical requirements. Any deviations or inadequate information is identified at that time. In addition, C.A.T & SCI coordinate any other reviews applicable to the particular evaluation (construction impacts, technical specialist review, etc.) and incorporate the results of these reviews on the technical bid evaluation.

The technical bid evaluation is then reviewed and approved by the Project Manager. At this point, C.A.T. area procurement department shall evaluate the bids based on project requirements and

commercial issues. Compliance with project requirements will be imposed on the vendor for all aspects of his equipment.

Once a bid is determined to be technically acceptable and commercially optimal, C.A.T. will send its recommendation to DAR for approval. C.A.T. will award purchase orders only upon obtaining QC/DAR approvals.

Upon receiving Company’s vendor approvals, C.A.T. will issue purchase orders to the selected vendors. All purchase orders are monitored. Suppliers will submit monthly progress reports to track the equipment status. Similarly, the shop drawings/production and delivery schedule report will depict, in details, the status of vendor drawings, data, factory acceptance tests and inspections, other relevant documents as requested.

All LLI will be received on site. All LLI will be checked upon receipt for quality, quantity, conformance with specifications, damage and tag or identification number, and entered on stock cards.

A receipt report and, if applicable, an overage, shortage or damage report will be prepared. Issue will be made on a materials requisition form signed by a signatory from a limited list of persons authorized by the project manager. The project procurement officer will oversee all locally supplied material. Receiving, warehousing, reporting and materiel issued for construction activities shall follow C.A.T. QA/QC procedures. Imported items will be received by purchase order number/tag number if appropriate, and checked for quantity and evidence of any shipment damage. Contractor will establish a construction warehouse system, which include covered and open storage to control the material until it is needed for construction. The Construction Manager will be responsible for issuing material transfer authorizations to release materials to the various Construction Superintendents.

The Procurement Officer will be responsible for providing marking and tagging instructions on all purchase orders. This effort will provide means in the identification of all materials received and establish traceability as required.

As project LLI are received, a report of materials received will be transmitted to update the records and generate reports for construction management and QC use. Material inventories will be adjusted as contractor issues materials and equipment for construction through standard material transfer document.

The procurement team will interface with the quality control function to ensure that materials and equipment are acquired without disrupting the design and construction schedules. Given the high coordination demands of this function, the Project Procurement Officer will serve as a key facilitator between the various elements of timely procurement. He will track the progress of materials and

(8)

equipment through delivery to the work site, providing a centralized point of information for all project management.

The project quality and project controls functions will supplement the procurement effort in support roles. Inherently linked by their common goals of vendor quality and schedule impact, these two functions will closely interface with Procurement throughout the life of the project.

The quality control function monitors the procurement function with each of its supporting positions. Working to ensure quality from both its subcontractors and vendors, this function assumes the role of quality assurance for its vendors and quality control for the entire project through continued analysis of our efforts as well as our vendors and subcontractors.

Where discrepancies are observed, non‐conformance reports will be prepared and submitted. Provision has been made for FAT tested and witnessed by QC and C.A.T.

The QA/QC Manager will verify the technical viability of potential vendors and subcontractors. Through a documented process and inspection, this coordinator will research the above criteria as well as the quality systems of potential suppliers.

The project Planning Engineer will predominantly assist in the scheduling and document control activities. Working with the Expediter on the area Procurement Department, the project Planning Engineer will develop procurement schedules, linking the relationship between procurement of specific equipment and materials with critical design and construction activities.

The Document Controller will maintain the officials vendor data control register, updating and tracking all vendor data processed for review/approval. The Document Controller will coordinate vendor communications, receiving and returning marked‐up and/or approved drawings or other vendor data. This data will include, but is not limited to, design calculations, parts lists, special tools, spare parts recommended by the vendor and various sub‐vendor documents.

Vendor data submissions will include drawings, spare parts data packages, operating and maintenance manuals/instructions, procedures, and other pertinent data needed to support the equipment or material being purchased.

On arrival of products to storage area, the storekeeper with the help of relative department (Mechanical, Electrical, etc) or his designate shall start unloading, checking against the purchase order or the loading note and labeling each item with its correct description, tally sheet number, stock number, drawing number, and store it in its proper place as advised by the specifications.
