Direct Answer / Executive Summary:

In public tenders conducted across the Kingdom of Saudi Arabia, government entities standardly mandate the Two-Envelope Bidding System (أسلوب المظروفين: الفني والمالي) to ensure technical merit and commercial competitiveness are evaluated with absolute objectivity. Governed by the Government Tender and Procurement Law (GTPL / نظام المنافسات والمشتريات الحكومية - Royal Decree No. M/128) and Ministry of Finance (MOF) regulations:

The Strict Segregation Mandate (GTPL Article 28): Commercial bidders must submit two separate, digitally sealed envelopes through the Etimad Portal (etimad.sa): Envelope 1: The Technical Offer (المظروف الفني) and Envelope 2: The Financial Offer (المظروف المالي). Under statutory law, any mention of pricing, unit rates, cost summaries, or commercial numbers inside the Technical Envelope triggers immediate, irreversible disqualification*.

Two-Stage Committee Evaluation: Bids undergo sequential evaluation by two independent statutory bodies: (1) The Tender Opening Committee (لجنة فتح العروض) unseals only the Technical Envelopes, while the Financial Envelopes remain cryptographically locked and encrypted by Etimad's system; (2) The Tender Evaluation Committee (لجنة فحص العروض)* scores technical competence against the RFP matrix. Only bidders who achieve the minimum technical passing score (typically 70% to 80%) advance to have their Financial Envelopes decrypted and evaluated.

Financial Envelope Contents: The Financial Envelope must contain: (1) The fully priced Bill of Quantities (BoQ / جداول الكميات); (2) Commercial terms and payment schedules; (3) The electronic Initial Bank Bid Bond (1% to 2%) linked via the SAMA digital gateway (or an official Monsha'at SME exemption letter); and (4) The statutory Local Content Baseline Plan (LCGPA)*.

Pre-Deadline Modification Rights (GTPL Article 29):* Bidders maintain the sovereign right to amend, substitute, or withdraw their submitted bid at any time prior to the official bid submission deadline. Once the portal clock expires, all submissions are frozen permanently.

Statutory Legal Framework: Articles 27 to 31 of the GTPL

The Two-Envelope procurement method is codified under Chapter 4 of the Government Tender and Procurement Law to eliminate bias and protect the integrity of public expenditure:

Statutory Pillars of Two-Envelope Bidding under the GTPL

Mandatory protections enforced by MHRSD & Saudi Labor Law

1
Article 27 (Methods of Submission)Authorizes contracting government entities to select either the Single-Envelope system (for standardized, routine off-the-shelf procurements) or the Two-Envelope system (mandatory for complex engineering, infrastructure, IT, and specialized consulting competitions).
2
Article 28 (The Non-Disclosure Principle & Automatic Disqualification)Strictly prohibits bidders from disclosing their financial pricing, discount schedules, or total values within the Technical Envelope. Mandates the evaluation committee to reject non-compliant bids immediately.
3
Article 29 (Right to Modify & Withdraw)Guarantees the bidder's right to alter, replace, or retract their technical or financial proposals via Etimad prior to the expiration of the deadline.
4
Article 30 (Committee Segregation & Sequential Opening)Forbids the Tender Opening Committee from decrypting financial offers until technical evaluation scores are finalized and formally approved.

The sequential two-envelope journey operates through a synchronized digital pipeline:

Anatomy of the Two Envelopes: What Belongs Where?

To avoid technical disqualification or commercial omissions, corporate bidding teams must understand the strict statutory segregation between both submission envelopes:

The Fatal Disqualification Trap: Accidental Pricing Disclosures

The most common and heartbreaking reason for bid rejection in Saudi public tenders is accidental price leakage inside the Technical Envelope:

The Absolute Non-Disclosure Doctrine (GTPL Article 28)

Mandatory protections enforced by MHRSD & Saudi Labor Law

1
If any document, schedule, chart, footnote, or appendix within the Technical Envelope contains a specific monetary figure indicating the bidder's total price, unit rate, software fee, or financial discount, the Tender Opening Committee is LEGALLY BOUND to reject the bid immediately.Neither the committee, the contracting ministry, nor the Minister of Finance possesses discretionary legal authority to overlook this defect.

Frequent Real-World Pricing Leaks That Cause Rejection:

1Gantt Charts with Monthly Billing Curves: Project schedules that include a row showing "Projected Monthly Invoicing: SAR 450,000". (Even estimated operational cash flows reveal pricing!).
2Key Personnel CVs with Historical Day Rates: Resumes of senior project managers or consultants that state "Current Commercial Rate: SAR 3,500/Day".
3Software & Equipment Technical Datasheets: Manufacturer brochures attached as technical appendices that contain recommended retail prices (RRP) or list prices.
4Subcontractor Letters of Support: Technical commitment letters from subcontractors stating "We agree to supply concrete at SAR 240/m³".
5Accidental Upload of the Bid Bond in the Technical Tab: Uploading the SAMA bank guarantee receipt into the Technical Envelope tab. Because the guarantee represents exactly 1% to 2% of the financial offer, attaching the guarantee instantly reveals the total financial bid value, triggering immediate disqualification!

Step-by-Step Bid Submission Guide on Etimad Portal

Executing a flawless two-envelope submission requires navigating the Etimad portal's dedicated bidding interface:

└────────────────────────────────────────────────────────────────────────┘

Step 1: Accessing the Bidding Module

1Log into `etimad.sa` using Nafath Single Sign-On.
2Navigate to "Tenders & Competitions" ──► "Purchased Tenders (المنافسات المشتراة)".
3Locate the target competition and click "Prepare and Submit Bid (إعداد وتقديم العرض)".
4The system presents a two-tab dashboard: "Technical Offer (العرض الفني)" and "Financial Offer (العرض المالي)".

Step 2: Preparing Envelope 1 (The Technical Offer Tab)

1Upload Technical Proposal File: Upload your comprehensive technical proposal in secure, searchable PDF format (typically under 100 MB). Ensure files are not password-protected.
2Statutory Compliance Certificate Validation:

Etimad verifies your Commercial Registration, ZATCA Tax Certificate, GOSI Insurance, and Qiwa Saudization* via real-time API.

If bidding on construction or maintenance tenders, attach your MOMRAH Contractor Classification Certificate*.

3Upload Technical Appendices: Attach engineering drawings, execution timelines, quality assurance plans, and health and safety manuals.
4Local Content Technical Commitments: Upload the mandatory LCGPA local-content commitments (e.g., list of national materials to be procured from domestic factories on the Mandatory List).
5Quality Review: Conduct a final keyword search across all technical PDFs for currency symbols (SAR, SR, Riyal, $) to confirm zero financial disclosures.
6Click "Save Technical Envelope (حفظ المظروف الفني)".

Step 3: Preparing Envelope 2 (The Financial Offer Tab)

1Pricing the Bill of Quantities (BoQ):

Method A (Direct Portal Entry):* Enter unit rates directly into the interactive Etimad BoQ table. The portal automatically calculates line-item totals and applies 15% VAT.

Method B (Standardized Excel BoQ):* Download the official Etimad Excel BoQ template, input unit rates into designated yellow cells without altering sheet formatting, and re-upload the spreadsheet.

2Total Offer Value Reconciliation: Ensure the calculated total on Etimad matches your internal commercial model down to the halala.
3Linking the SAMA Digital Initial Bid Bond (1%–2%):

Navigate to the "Bank Guarantees"* section inside the Financial Offer tab.

Click "Link Digital Guarantee"*. The portal displays all active guarantees issued by your Saudi commercial bank matching this specific Etimad tender reference number.

* Select your digital guarantee. The system confirms that the guarantee amount satisfies the statutory percentage (1% to 2%).

If an SME: Select "Monsha'at SME Exemption"* and attach your official SME Classification Certificate and electronic commitment letter.

4Local Content Financial Baseline Form: Attach the signed and stamped LCGPA financial baseline declaration detailing historic domestic spending ratios.
5Click "Save Financial Envelope (حفظ المظروف المالي)".

Step 4: Digital Signing & Cryptographic Submission

1Review the Comprehensive Submission Summary Card.
2The authorized signatory clicks "Sign and Submit Bid (توقيع وتقديم العرض)".
3Authentication is finalized via a one-time passcode (OTP) routed through Nafath.
4Etimad applies a cryptographic hash and timestamp to both envelopes.
5The portal generates an official Electronic Bid Receipt (إشعار استلام العرض) containing:

* Unique Bid Submission Reference Number.

* Precise Gregorian and Hijri timestamp down to the second.

* Cryptographic verification checksum confirming file integrity.

6Download and archive this receipt immediately. It is your sole statutory proof of timely bid delivery.

Modifying or Withdrawing Bids Before the Submission Deadline

Circumstances often arise where an estimating team discovers an arithmetic error, receives an improved vendor discount, or decides to retract an offer before the competition closes.

Under Article 29 of the GTPL, bidders possess complete statutory autonomy:

    F --> H["Portal cancels submission; initial bank guarantee unlinked; zero penalty!"]

1. Amending a Submitted Offer (تعديل العرض):

As long as the submission deadline has not passed, the vendor clicks "Amend Bid" on Etimad.
The system retracts the submitted package, reverting it to editable draft status.
The vendor can upload a revised technical proposal, adjust BoQ unit prices, or update the bank guarantee.
Crucial Rule: The revised bid must be formally re-submitted and re-signed via Nafath before the deadline clock expires. An open, unsubmitted amendment draft is treated as a total failure to submit!

2. Formally Withdrawing an Offer (سحب العرض):

If a company decides to abandon its bid prior to the deadline, it clicks "Withdraw Bid".
The submission is canceled instantly.
Zero Financial Penalty: The digital initial bank guarantee is immediately unlinked and released back to the vendor's commercial bank. The government entity has zero legal right to confiscate the bid bond for pre-deadline withdrawals.

The Evaluation Mechanics: Quality-Cost Based Selection (QCBS)

In modern Saudi public procurement, government entities rarely evaluate tenders on the basis of lowest financial price alone. High-value, complex projects are governed by the Quality-Cost Based Selection (QCBS) framework:

Statutory Blended Evaluation Formula

Mandatory protections enforced by MHRSD & Saudi Labor Law

1
Final Composite Score = [Technical Score Weight × Technical Points] + [Financial Score Weight × Financial Points] + [Local Content Score]
2
Typical Scoring Weights• Technical Proposal: 30% to 40% (Evaluation of methodology, team, and delivery track record). • Financial Offer: 40% to 50% (Competitiveness of pricing relative to peer bids). • Local Content (LCGPA): 10% to 20% (Baseline score and domestic supply commitments).

The Two-Stage Gating Threshold:

1The Technical Filter: The Tender Evaluation Committee scores technical proposals against predefined criteria. Bidders scoring below the threshold (typically < 70.0%) are declared Technically Non-Compliant.
2The Financial Opening: Only bidders meeting or exceeding the technical threshold have their Financial Envelopes decrypted.
3The Local Content Price Preference Adjustment: In supply tenders, a 10% price preference margin is applied to national products; certified SMEs receive up to an additional 10% preference margin against large corporate competitors.

Case Study 1: "SmartInfra KSA" — Disqualified by a Gantt Chart

Bidder Profile: Grade-2 electrical and smart-city infrastructure contractor bidding on an SAR 28,000,000 municipal surveillance tender.
The Error:

* SmartInfra prepared an exceptional 180-page technical proposal detailing cutting-edge fiber-optic transmission protocols.

* In Section 4.3 (Project Execution Schedule), the project manager included a detailed Microsoft Project Gantt chart.

Below the milestone bars, a financial tracking row was included: "Monthly Billing Estimate: Month 1 = SAR 600,000; Month 2 = SAR 1,200,000; Total Phase 1 Billing = SAR 8,400,000"*.

The Statutory Outcome:

* The Tender Opening Committee opened the Technical Envelope and immediately flagged Section 4.3.

Under Article 28 of the GTPL, the committee declared the bid disqualified due to commercial pricing leakage inside the technical proposal*.

* SmartInfra's Financial Envelope remained permanently locked. The contractor was disqualified, and the contract was awarded to a competitor bidding SAR 31,500,000.

The Result: CloudCore passed technical gating effortlessly, achieved the highest composite financial-technical score, and won the contract award.

Top 7 Compliance Hazards in Two-Envelope Bidding

Avoid these frequent mistakes that jeopardize multimillion-riyal tenders:

Critical Pitfalls in Two-Envelope Submissions

Mandatory protections enforced by MHRSD & Saudi Labor Law

1
Pricing Disclosures in Technical SchedulesIncluding cash-flow projections, equipment cost tags, or personnel day-rates anywhere inside technical proposals.
2
Linking the Bank Guarantee in the Wrong TabAttaching the bank guarantee within the Technical Envelope tab instead of the Financial Envelope tab.
3
Excel BoQ Formatting CorruptionModifying column headers, deleting rows, or breaking formulas in the standardized Etimad Excel BoQ file. Altered BoQs are rejected by Etimad's automated importer.
4
Uploading Corrupted or Password-Protected PDFsSubmitting encrypted files that cannot be opened by the committee. The committee will not request passwords; unreadable files are treated as missing submissions.
5
Miscalculating VAT in Financial TotalsSubmitting a financial price that omits the statutory 15% VAT calculation when the tender booklet mandates gross pricing.
6
Last-Minute Submission Network BottlenecksAttempting to upload multi-hundred-megabyte files in the final 30 minutes before the portal deadline. Network timeouts can prevent timely cryptographic sealing.
7
Omitting LCGPA Local Content DocumentationFailing to attach the official Local Content Baseline Form inside the Financial Envelope, forfeiting critical price preference margins.

Executive Two-Envelope Submission Pre-Flight Checklist

Ensure your bidding team verifies every element before applying the final Nafath signature:

[ ] Technical Offer Stripped of All Pricing: Run automated text searches for SAR, SR, Riyal, and numeric totals across all technical files to guarantee absolute non-disclosure.
[ ] Unpriced BoQ Verified: Ensure the technical offer includes an unpriced BoQ confirming scope coverage without unit rates.
[ ] Statutory Compliance Certificates Active: Confirm that CR, Chamber, ZATCA, GOSI, Qiwa, and MOMRAH classification certificates are valid and synced.
[ ] BoQ Excel Sheet Validated: Confirm that all unit rates are populated, arithmetic sums reconcile, and cell formatting matches the original Etimad template.
[ ] SAMA Digital Bid Bond Linked in Financial Tab: Verify that the 1% to 2% digital guarantee reference appears correctly inside the Financial Offer tab.
[ ] Local Content (LCGPA) Annexes Attached: Include the completed Local Content Baseline Plan and SME declarations.
[ ] Submission Deadline Confirmed: Ensure the entire package is finalized and submitted at least 4 to 6 hours before the official portal deadline.
[ ] Electronic Bid Receipt Downloaded: Download and store the timestamped Etimad Bid Submission Receipt containing the cryptographic hash.

Frequently Asked Questions (FAQ)

What happens if I accidentally include pricing inside the Technical Envelope on Etimad?

Under Article 28 of the Government Tender and Procurement Law (GTPL), including any financial pricing, unit rates, cost summaries, or fee disclosures inside the Technical Envelope results in immediate and irreversible disqualification. The Tender Opening Committee is legally bound to reject the bid without opening the Financial Envelope.

Where should the initial bank bid bond be uploaded on Etimad?

The initial bank guarantee (1% to 2%) must be linked exclusively within the Financial Envelope tab (*المظروف المالي*). Uploading or referencing the bank guarantee inside the Technical Envelope is strictly prohibited, as the guarantee amount directly reveals the total financial bid value, triggering statutory disqualification.

Can a bidder modify their technical or financial bid after submitting it on Etimad?

Yes, provided the submission deadline has not passed. Under GTPL Article 29, a bidder has the statutory right to amend, replace, or withdraw their offer at any time prior to the official bid closing deadline. Once the portal deadline expires, all bids are cryptographically frozen and cannot be altered.

How does the Tender Opening Committee handle the two envelopes on Etimad?

Upon the arrival of the bid opening deadline, the Tender Opening Committee unseals only the Technical Envelopes. The Financial Envelopes remain cryptographically locked and encrypted by the Etimad platform. Only after the Tender Evaluation Committee completes technical scoring and approves qualified bidders are the Financial Envelopes decrypted and opened.

What is the passing score for technical evaluation in government tenders?

The minimum technical passing threshold is defined by the contracting government entity in the official Tender Booklet (كراسة الشروط والمواصفات). It is standardly set between 70.0% and 80.0% (70 to 80 points out of 100). Bidders scoring below this threshold are eliminated from the competition, and their Financial Envelopes are never opened.

Does the lowest financial price always win a Two-Envelope competition?

No. While financial competitiveness is critical, awards in Two-Envelope competitions are governed by either: (1) The lowest financial offer among technically qualified bidders (subject to LCGPA national price preferences); or (2) A Quality-Cost Based Selection (QCBS) formula that blends technical score (30%–40%), financial score (40%–50%), and local content score (10%–20%).
