How Government Tender Evaluation Works

You have submitted your bid, the box has been sealed and the opening is over. What happens next? For many bidders, the weeks between bid opening and award notice are a black box. Understanding how tender evaluation Sri Lanka procuring entities carry out actually works helps you prepare bids that survive every stage, interpret the outcome, and know your options if you disagree with a decision.

This guide walks through the evaluation process for goods and works under the general framework of the National Procurement Commission (NPC) Procurement Guidelines, including who evaluates, the stages a bid passes through, how prices are compared, and how awards and complaints are handled. Consultancy selection follows a different, quality-based process, which is touched on briefly.

Procedures are revised from time to time and can differ by procuring entity, contract size and funding source. Always verify requirements in each tender's bidding documents.

The Principles Behind Evaluation

Public procurement in Sri Lanka rests on principles such as transparency, fairness, equal opportunity, competition, economy and accountability. In evaluation these translate into a simple but strict rule: bids must be evaluated only against the criteria stated in the bidding document. Evaluators cannot introduce new requirements after bids are opened, and bidders cannot change the substance of their bids to make them acceptable.

This is why the bidding document, including the bid data sheet and any addenda, is the most important reference for both sides.

Who Evaluates Bids?

Technical Evaluation Committee (TEC)

A TEC is appointed for the procurement. It usually includes officers with technical knowledge of the subject, and sometimes independent experts. The TEC examines bids in detail and prepares an evaluation report with its recommendation.

Procurement Committee

The TEC's recommendation is submitted to the procurement committee at the level appropriate for the contract's value. This committee reviews the report, can ask questions or seek clarifications, and makes the award decision, or recommends it to a higher authority where required.

Integrity Requirements

Committee members are generally required to declare any conflict of interest and keep evaluation information confidential until the award is announced. Bidders must not try to influence evaluators; doing so can lead to rejection and other consequences.

The Stages of Tender Evaluation

The following stages are typical for goods and works procurements using competitive bidding.

Stage 1: Bid Opening

Before evaluation begins, bids are opened publicly. The bid opening record notes bidder names, bid prices, discounts, alternative bids where allowed, and whether bid security was provided. Bids received after the deadline are not opened. The opening record is important because evaluators work from what was read out and recorded.

Stage 2: Preliminary Examination

The TEC first checks each bid for basic completeness and eligibility, for example:

• Is the bid signed by an authorised person?
• Is the bid security present, in the correct form, amount and validity?
• Is the bidder eligible, for example not debarred and of eligible nationality where restricted?
• Are required documents and forms included?
• Is the bid validity period as required?

Bids failing a critical requirement at this stage may be rejected without further evaluation.

Stage 3: Determination of Responsiveness

The TEC then determines whether each bid is substantially responsive, meaning it conforms to all key terms, conditions and specifications without material deviation, reservation or omission. A material deviation is one that would:

• Affect the scope, quality or performance of the contract in a substantial way.
• Limit the buyer's rights or the bidder's obligations under the contract in a substantial way.
• Unfairly affect the competitive position of other bidders if corrected.

Minor, non-material deviations may be accepted, and in some cases the committee can request clarification or correction of non-material omissions under the rules in the bidding document. Bidders cannot use clarification to change their price or the substance of the bid.

Stage 4: Technical Evaluation

For bids that are responsive, the TEC evaluates technical compliance in detail, such as:

• Specifications of offered goods against requirements.
• Samples or catalogues where requested.
• Methodology, work programme and equipment for works.
• Key personnel qualifications.
• Delivery schedules and after-sales service.

Most goods and works evaluations are pass/fail on technical compliance, rather than scored. Scoring is more typical for consultancy and certain complex procurements.

Stage 5: Correction of Arithmetic Errors

The bidding document sets rules for correcting arithmetic errors, for example which figure prevails if unit price and total do not match. The corrected price becomes binding. If a bidder does not accept the correction, the bid may be rejected and the bid security could be at risk, depending on the document.

Stage 6: Price Evaluation and Comparison

The TEC compares responsive bids using the evaluated bid price. Depending on the document, adjustments may include:

• Discounts offered unconditionally.
• Conversion of currencies to a single currency, for international bids.
• Application of a domestic preference margin, where permitted.
• Pricing of minor omissions using rules stated in the document.
• Other stated factors, such as delivery schedule or operating costs, where the document says they will be considered.

Bids are then ranked from lowest to highest evaluated price.

Stage 7: Post-Qualification

The bidder with the lowest evaluated substantially responsive bid is checked against the qualification criteria, such as:

• Financial capacity, including turnover and access to credit.
• Experience in similar contracts.
• Personnel and equipment.
• Litigation history, where relevant.
• CIDA grading for works.

If the bidder passes, the TEC recommends award. If it fails, the next-ranked bid is assessed in the same way.

Stage 8: Abnormally Low Bids

Where a bid seems abnormally low relative to the estimate or other bids, the committee may ask the bidder to explain how it can perform at that price. If the explanation is not satisfactory, the bid may be rejected or additional security required, according to the bidding document and guidelines.

Summary of Evaluation Stages

| Stage | Key question | Typical outcome if failed | |---|---|---| | Bid opening | Was the bid received on time? | Late bid not opened | | Preliminary examination | Is the bid complete, signed and secured? | Bid may be rejected | | Responsiveness | Does it conform without material deviation? | Bid rejected as non-responsive | | Technical evaluation | Does it meet specifications and scope? | Bid rejected | | Arithmetic correction | Are calculations correct? | Price corrected; rejection if not accepted | | Price comparison | Which bid has the lowest evaluated price? | Bid ranked accordingly | | Post-qualification | Can the bidder perform the contract? | Next bidder considered |

Example: A Hypothetical Evaluation

This is a hypothetical example with round numbers for illustration only.

A district hospital procures laboratory equipment. Six bids are opened, ranging from Rs. 30 million to Rs. 45 million.

• Bid A (Rs. 30 million) is rejected at preliminary examination because the bank guarantee validity is shorter than required.
• Bid B (Rs. 32 million) offers equipment that fails a key technical specification, so it is non- responsive.
• Bid C (Rs. 34 million) has an arithmetic error; after correction its price becomes Rs. 34.5 million, which the bidder accepts.
• Bids D, E and F are responsive but higher priced.

Bid C is the lowest evaluated substantially responsive bid. Post-qualification confirms that Bidder C has the required experience and financial capacity, so the TEC recommends award to Bidder C.

The lesson: two lower bids were lost not because of price, but because of a guarantee date and a specification.

Award, Notification and Appeals

After the procurement committee approves the recommendation, the procuring entity notifies the successful bidder. Under the current framework, unsuccessful bidders are typically informed of the outcome and may be given a period to seek a review or lodge an appeal under the applicable procedures. The details, including time limits and the body that handles appeals, are set in the guidelines, regulations and bidding document, so check them promptly if you plan to challenge a decision.

The successful bidder then submits a performance security, and the contract is signed. Bid securities of unsuccessful bidders are returned according to the document's terms.

Requesting a Debriefing

Even if you do not appeal, it is worth asking the procuring entity, politely and in writing, for feedback on why your bid was not successful, where their procedures allow. This can help you improve future bids.

How Consultancy Evaluation Differs

For consultancy services, evaluation is usually based on a technical score covering experience, methodology and key experts, sometimes combined with a financial score. Technical proposals are opened and scored first, and only qualifying firms' financial proposals are opened. Negotiations may follow with the top-ranked firm.

How to Make Your Bid Evaluation-Proof

• Read the evaluation criteria section first, then build your bid around it.
• Use the checklist approach for preliminary examination items: signatures, bid security, validity, forms.
• Avoid deviations. If you must deviate, understand whether the bidding document allows it and how it will be evaluated.
• Double-check arithmetic in every price schedule.
• Provide evidence for qualification exactly as specified, including formats and periods.
• Respond quickly to clarification requests from the committee, without changing your price or the substance of your bid.
• Keep records of your submission, including copies and proof of delivery.

Key Takeaways

• Tender evaluation in Sri Lanka follows the criteria stated in the bidding document and nothing else.
• Bids pass through opening, preliminary examination, responsiveness, technical evaluation, arithmetic correction, price comparison and post-qualification.
• The contract goes to the lowest evaluated substantially responsive bid from a qualified bidder.
• Many bids fail on documents, not price.
• Unsuccessful bidders may have review or appeal rights within set time limits.

Pre-Submission Evaluation Checklist

• Bid signed by authorised person, with proof of authority
• Bid security correct in form, amount, issuer and validity
• Bid validity period matches the requirement
• All forms completed without alteration
• Specifications met line by line
• Arithmetic checked in all schedules
• Qualification evidence attached as specified
• Addenda acknowledged

Frequently Asked Questions

How long does tender evaluation take?

It varies with the size and complexity of the procurement and the approval levels involved. Bids remain valid for the stated bid validity period, and entities aim to complete evaluation within that time.

Can the committee contact me during evaluation?

Yes, the committee may request clarifications in writing. You should respond as asked, but you cannot change your price or the substance of your bid.

Why was my lowest bid rejected?

Common reasons include missing or incorrect bid security, lack of authorised signature, material deviations from specifications, failure to meet qualification criteria, or not accepting arithmetic corrections.

Is technical evaluation scored for goods and works?

Usually it is pass/fail. Scoring is more typical for consultancy and some complex procurements, as stated in the bidding document.

Can I see the evaluation report?

Evaluation reports are generally confidential during the process. After award, bidders may receive information about the outcome. Ask the procuring entity about what can be shared under current rules.

What can I do if I disagree with the decision?

The procurement framework provides review or appeal mechanisms with strict time limits. Check the bidding document and current regulations promptly and follow the stated procedure.

Conclusion

Tender evaluation is a structured, rule-bound process. Every stage asks a specific question, and a bid must answer each one correctly to win. By understanding these stages and building your bid around the evaluation criteria, you can stop losing contracts to avoidable errors and compete on what matters: price, quality and capability. Because procedures change, confirm the details with each procuring entity and bidding document.
