For effective construction project management, it is essential to maintain an organized and transparent procurement process, particularly for provisional sum packages executed by subcontractors. To ensure project quality and minimize risks, the Main Contractor follows a structured six-stage procurement lifecycle. This lifecycle begins with the development of a comprehensive Procurement Packaging Plan and concludes with the Contract Award.

  The process is designed to identify the most qualified partners through comprehensive Pre-Qualification, Tendering, and Technical & Commercial Evaluation stages. By adhering to these standardized procedures, the Main Contractor ensures that every appointed subcontractor demonstrates strong financial stability, robust safety performance, and a proven commitment to excellence.
Effective coordination and close cooperation between the Main Contractor, the PMC, and the Employer are essential to the successful delivery of the following processes. 

The following stages primarily focus on packages to be executed by subcontractors under the main contractor. Items that will be self-performed under the PS scope will be discussed separately.

What is provisional Sum ?

A provisional sum is an allowance included in the contract price for work, services, or materials that are not fully defined at tender stage, so the exact cost cannot yet be fixed. In FIDIC practice, it is used for uncertain scope and is later valued based on the actual work instructed, usually with the contract’s agreed overhead and profit mark-up.In simple terms, it's like a placeholder amount, not a final price. It gives the Employer flexibility to proceed before every detail is known, while preserving a mechanism to adjust the Contract Price once the scope becomes clear.

Procurement Steps

Stage 1: Procurement Packaging Plan & Preparing the Bidder List

Phase Overview: The Main Contractor initiates the procurement lifecycle by defining the package scope and conducting a rigorous multi-layered screening process to ensure only highly qualified and compliant bidders reach the tendering stage.

  • Step 1: Procurement Packaging Plan (PPP) Development The Main Contractor develops a comprehensive PPP for the Employer’s review and approval. This plan defines the provisional sum packages, budgets, and procurement timelines. In conjunction, a "Long List" of potential bidders is identified through in-depth market research and the Employer’s recommended subcontractor list.
  • Step 2: Expression of Interest (EOI) & Market Engagement To ensure a competitive environment and verify bidder availability, a formal EOI is issued to the Long List. This document outlines the high-level scope, anticipated deliverables, and key milestones.
    • Action: Bidders must formally execute and stamp the EOI to confirm their interest and current resource capacity.
    • Filter: Only bidders who pass the EOI "interest and availability" check proceed to pre-qualification.
  • Step 3: Pre-Qualification Questionnaire (PQQ) Issuance Interested bidders are issued a formal PQQ to assess their capabilities across several critical pillars:
    • Legal & Eligibility: Valid business licenses (CR, Zakat, GOSI, etc.).
    • Financial Stability: Submission of audited financial reports for the latest three years to assess fiscal health.
    • Technical Experience: Track record of success on projects of similar scale and complexity.
    • Resources: Organizational charts, CVs of key staff, and equipment lists.
    • Quality & Sustainability: Evidence of Quality Management Systems and proficiency in Sustainability, Building Physics, and Environmental Permitting.
    • BIM & Safety: Assessment of BIM application in past projects and submission of comprehensive HSE policies and safety plans.
  • Step 4: Compliance Evaluation & Scoring System The Main Contractor performs a structured evaluation using a pre-approved scoring system and a Compliance Sheet.
    • Must-Have Criteria: Bidders must meet baseline requirements (e.g., specific insurance or grade of license). Failure to meet these results in immediate disqualification.
    • Scoring: Remaining bidders are scored based on the weighted criteria. This ensures the evaluation is objective and grounded in data.
  • Step 5: Final Shortlist & Employer Approval Based on the scoring summary, the Main Contractor identifies a minimum of few potential bidders to ensure at least three competitive quotations can be obtained. The final Shortlist of Bidders, supported by the PQQ Scoring Report and Compliance Sheet, is submitted to the Employer for formal approval.

Stage 2: Tender Preparation

Phase Overview: In this stage, the Main Contractor finalizes the "Tender Dossier." This ensures all technical, commercial, and interface requirements are explicitly defined before the package is issued to the shortlisted bidders.

  • 1. Step 1: The Tender Package Components The package is divided into key volumes to ensure a professional and organized submission:
    • Contractual & Legal Documents:
      • Conditions of Subcontract (General and Particular).
      • Subcontract Data (Project-specific parameters).
      • Form of Subcontract Agreement.
      • Non-Disclosure Agreement (NDA) – to be signed before document release.
      • Instruction to Tenderers (ITT).
    • Technical Documents:
      • Detailed Subcontract Specifications.
      • Tender Drawings and BIM Models.
      • Scope of Works (SOW) narrative.
    • Project Controls & Compliance (Schedules):
      • Interface & Responsibility: Interface Scope Delineation Matrix (MC – Subcontractor) and Attendance Matrix.
      • Commercial: Priced Bill of Quantities (BOQ), Dayworks Schedule, and Schedule of Payments.
      • Planning: Project Master Schedule and Milestone Dates.
      • Standards: HSE Policies, Environmental Sustainability requirements, and Quality Control procedures.
      • Logistics: Site Logistics Plan and List of Plant & Materials.
  • 2.Step 2: Interface & Risk Alignment
  • Before the package is authorized for release, the following internal checks are performed:
    • Gap Analysis: Review the Interface Matrix to ensure no "grey areas" exist between this package and other trades (e.g., ensuring power supply or scaffolding is assigned to a specific party).
    • Back-to-Back Check: Confirm that all obligations from the Main Contract are properly "flowed down" into the Subcontract documents.

      Stage 3: Procurement Stage

      • Step 1: Managing Clarifications & Site Visits
        • The Main Contractor addresses subcontractor inquiries using designated communication platforms. This includes conducting site visits or walkthroughs and hosting pre-bid meetings to resolve technical or commercial questions, ensuring all bidders have a clear understanding of the project conditions.
      • Step 2: Issuance of Addendums & Time Extensions (if needed)
        • Based on the clarification process and any changes in requirements, formal addendums are issued to all bidders to ensure the scope remains clear and consistent for all parties.
        • If bidders request more time to submit their proposals due to the complexity of the scope or late addendums.
      • Step 3: Submission of Technical Proposals
        • Bidders submit their technical offers directly to the appropriate delivery lead. The technical proposal must include:
        • Technical Form of Tender / Cover Letter: A formal letter agreeing to the tender conditions and acknowledging the receipt of all addenda, but with all prices left blank.
        • Tender Security / Bid Bond: A bank guarantee (usually a percentage of the estimated contract value) proving the contractor is serious and financially stable enough to bid.
        • Proposed Project Schedule (Baseline Program): A detailed timeline (often exported from Primavera P6 or MS Project) showing the critical path, milestones, and sequences of work.
        • Method Statements: Detailed, step-by-step descriptions of exactly how the contractor will execute complex or critical activities (e.g., deep excavations, heavy lifting, or concrete pouring).
        • Organization Chart & Key CVs: A chart showing the management structure for the site, accompanied by the resumes of the proposed Project Manager, Construction Manager, QA/QC Manager, and HSE Manager.
        • Plant and Equipment Schedule: A list of the heavy machinery (cranes, excavators, concrete pumps) the contractor owns or intends to lease for the project.
        • Proposed Subcontractors & Suppliers: A preliminary list of the specialized companies the main contractor intends to use for specific trades (like MEP, facade, or elevators).
        • HSE (Health, Safety, and Environment) Plan: A project-specific policy outlining how the contractor will prevent accidents and manage site safety.
        • QA/QC (Quality Assurance / Quality Control) Plan: A framework detailing how the contractor will inspect materials, manage testing, and ensure the work meets the IFT specifications.
      • Step 4: Submission of Commercial Proposals
        • Bidders submit their commercial offers directly to the appropriate delivery lead. The commercial proposal must include:
        • Commercial Form of Tender: The official cover letter stating the total, final Lump Sum or Estimated Tender Price. This is the legally binding number.
        • Priced Bill of Quantities (BOQ): The fully completed spreadsheet where the contractor has filled in their specific unit rates (labor, material, equipment, and markup) for every single item of work.
        • Schedule of Daywork Rates: A list of standard hourly rates for labor and equipment. This is used later during the construction phase to price minor Variation Orders or out-of-scope work that can't be measured by the BOQ.
        • Preliminary Cash Flow Forecast: A month-by-month projection showing how much the contractor expects to bill the client throughout the project lifecycle.
        • Priced Value Engineering (VE) or Alternative Offers: If the ITT allowed it, this is a separate section where the contractor offers a cheaper, alternative design or material, clearly showing the cost savings compared to the base bid.
      • Step 5: Opening of Commercial Bids
        • The Employer proceeds to open the bids from qualified participants. If the Main Contractor is not bidding themselves, their representative must be present to receive copies of the documentation to ensure transparency and coordination.

      Stage 4: Evaluation & Approval

      The Main Contractor is responsible for preparing the technical evaluation for Employer approval, unless the Main Contractor or its affiliates are bidding, in which case the PMC conducts the evaluation. Subsequently, the PMC reviews the commercial evaluation. Bidders receive a Post Tender Clarification (PTC) and submit their Best and Final Offer (BAFO) via sealed bids. Key components of this stage include:
      Evaluation: A comprehensive assessment of technical (30%) and commercial (70%) bid aspects with relevant stakeholders.

      • PTC: Arrange meetings for PTC
      • BAFO: Subcontractors will submit their best and final price inside closed sealed Bid.
      • LAFO: Subcontractors will submit their last and final price inside closed sealed Bid.
      • LAFO evaluation: Main Contractor will make a final commercial evaluation based on LAFO closed Bid outcomes then it will be approved by the Employer.

      Stage 5: Final Recommendation & Award Instruction

      The Main Contractor is responsible for submitting a Works Package Proposal for the Employer's approval. In accordance with the milestones established in the PS Procurement Tracker, the Employer's Representative shall notify the Contractor of the decision to either:

      • Accept the proposal, authorizing the Contractor to immediately execute the Works Package Contract with the approved candidate, who will then be recognized as a Subcontractor.
      • Reject the proposal, providing specific justifications for the refusal. In this instance, the Representative will define a timeframe for the Contractor to submit a corrected Works Package Proposal that addresses the identified issues for subsequent review and final determination.

      Stage 6: Contract Award

      Upon the release of the Engineer Instruction (EI) along with the IFC Package, the Main Contractor will immediately initiate the contracting phase to prevent any delays in resource mobilization or the commencement of work. This stage represents a vital transition, moving the project from planning and approvals into the execution phase.
      Till finalizing the contract signing procedures, and to facilitate an immediate start for subcontractors, a Letter of Award (LoA) may be issued when necessary.

      • Formal Notification to the Selected Bidder: Upon issuance of the EI, the Main Contractor will officially advise the successful subcontractor of their selection. This communication will outline essential contract parameters, including the work scope, project schedules, and any necessary compliance conditions.
      • Performance Bond: The successful bidder to provide a guarantee (usually 10%) upon contract award.
      • Finalizing the Contract: Within the designated 30-day window, the Main Contractor will complete all legal documentation. This phase ensures that all provisions are explicitly defined and mutually accepted. Both parties will execute the agreement via wet signature, confirming that all prerequisites are met and the subcontractor is prepared for resource mobilization.
      • Advance Payment Guarantee: If the subcontractor requires an up-front payment for mobilization or materials, the process for securing this with a bank guarantee is missing.
      • Site Kickoff Preparation: In parallel, the Main Contractor and subcontractor will coordinate an on-site kickoff meeting. This vital session aligns the Main Contractor, the subcontractor, and relevant stakeholders to finalize logistical arrangements, conduct a comprehensive scope review, establish performance expectations, and resolve any pending concerns prior to commencement.
      • Continuous Communication and Coordination: The Main Contractor will sustain proactive dialogue with the subcontractor and project personnel throughout this transition. Any emerging risks or potential delays will be managed immediately to protect the project's established timeline.

      Main Contractor guarantees a seamless transition to the execution phase by undertaking these actions immediately following the issuance of the EI, thereby reducing downtime and laying the groundwork for effective project delivery. This strategic methodology assists in maintaining the project schedule and budget, while confirming that every stakeholder is prepared to commence operations at the earliest opportunity.
