Stage Zero: The project does not yet exist, but the forecast has already appeared

The Development Bureau maintains a "Construction Industry Tender Gazette", which includes "Advisory Study Forecasts and Engineering Tender Forecasts". This is the earliest public signal on the entire timeline: the government gives advance notice of what advisory studies it intends to launch and what engineering projects will be tendered in the coming period. At this stage there are no tender documents, no closing dates, and not even a contract number.

For advisory firms, the forecast is the most valuable page, because the upfront preparation for advisory work (forming a team, finding specialist sub-consultants, reserving manpower) often takes several months. For contractors, the forecast is used for reverse reasoning: if a project is now undergoing a feasibility study, the main works tender is usually one to three years away, which determines whether you need to upgrade your group on the approved list in the meantime.

OpenTender.hk marks such records as forecast stage and excludes them from the main dashboard, because they are not biddable opportunities. To view them, go directly to the Development Bureau's tender gazette page.

In practice there is a way to judge: pay attention to the wording of the project name in the forecast. Those written as "feasibility study" or "survey and design" mean the main works are still far off; those written as "detailed design" or "site investigation" usually mean the main works have entered the preliminary stage. The same place name appearing two or three times in forecasts with progressively narrower wording is a signal that the project is genuinely advancing, rather than a wishful line in a planning document.

A forecast is not an opportunity, it is a timetable. It tells you how much time you have left to prepare your qualifications.

Stage 1: Invitation to Submit Expression of Interest (EOI)

An Expression of Interest (EOI) invitation is an action by the government to gauge the market before formal tendering. The notice sets out the general scope of the project and invites interested companies to submit information. Submitting an EOI usually does not constitute a tender, nor does it guarantee that you will be invited to tender, but in advisory selection it is often a necessary condition for proceeding to the next round — the procuring unit may "invite advisory firms that have submitted an expression of interest and been preliminarily shortlisted to submit proposals".

In other words, for advisory firms, missing the EOI means missing the entire project, because subsequent invitations for proposals are sent only to companies on the list and will not be openly tendered again. This is one of the most important differences between advisory and engineering contracts.

On OpenTender.hk, the category field for such records is often written as Expression of Interest or Request for Information, and these are consolidated under the "Prequalification and Expression of Interest" category.

An EOI submission usually does not require pricing; the focus is on proving you have done similar work. The government will look at whether you have reference projects of comparable scale, whether the team has relevant qualifications, and whether you can deploy manpower within the project period. This means an EOI is in fact a document that can be prepared in advance: compile your company's similar projects over the past five years, the professional qualifications of key personnel, and specialist sub-consultant partners into a reusable draft, so that when an EOI comes up you only need to adjust it per project — far quicker than writing from scratch at short notice.

Another often overlooked detail is the contact person. EOI notices generally list the responsible officer's phone or email; clarifying scope questions before submission is entirely legal and encouraged, rather than waiting until you receive an invitation to submit a proposal.

Stage Two: Prequalification, determining who is eligible to receive the tender documents

Prequalification tendering is used for projects with particularly high technical requirements or particularly high risks. The government will publish a notice in the Gazette inviting companies to participate in prequalification; the list of successful applicants must be approved by the Permanent Secretary for Financial Services and the Treasury (Treasury) after considering the advice of the Central Tender Board, and thereafter only companies on the list will receive tender invitations.

The significance of this step is: the prequalification notice is public, but the subsequent tender invitations are not. If you do not participate in the prequalification stage, even if you later learn of the project, you will have no way to bid. Therefore, for large projects, the prequalification notice is the real tender closing date.

It is important to distinguish between prequalification and selective tendering. Selective tendering involves sending letters to companies on the approved list inviting them to tender; you will receive an invitation as long as you are in the relevant category and group on the list; moreover, for procurement governed by the WTO Government Procurement Agreement, companies not on the list will also be considered except in special circumstances. Prequalification, on the other hand, involves a separate round of assessment for a single project, and the list of successful applicants applies only to that project; it is a separate matter from your status on the approved list—being in Group C of the list does not mean automatic prequalification for a particular project.

• Prequalification notices are published in the Gazette, on the internet, and sometimes additionally in local newspapers and foreign industry magazines
• The list of successful applicants must be approved by the Central Tender Board's advice and the Permanent Secretary for the Treasury
• Subsequent tender invitations are issued only to successful applicants and are no longer public
• See the category field on OpenTender.hk for Prequalification or Invitation for Prequalification

Stage Three: Tender notices, and the three monetary thresholds that determine the tendering method

The Stores and Procurement Regulations provide that procurement exceeding specified thresholds shall generally be subject to open tender. The three thresholds are: goods or general services exceeding $1.35 million, consultancy services exceeding $3 million, and construction and engineering services exceeding $7 million. Contracts below these amounts may use simpler procedures and may not appear in the Gazette.

This explains a common question: why some government works appear never to have been openly tendered. Below the thresholds, notices may appear only on departmental websites, or may be handled simply by quotation. The Financial Services and the Treasury Bureau's tender notice page lists departmental tender pages by department and procurement nature, and is the only near-complete official index.

Also note procurement covered by the WTO Government Procurement Agreement. For government departments, the threshold for construction services is 5,000,000 SDR, and for goods and specified services is 130,000 SDR; for non-government public bodies (including the Airport Authority, Hospital Authority and Housing Authority), the threshold for goods and services is higher at 400,000 SDR. For procurement covered by the Agreement, the tender period is usually at least 40 days, considerably longer than the general minimum of three weeks.

Stage 4: Tender Closing, a moment more unforgiving than imagined

Tenders must be placed in the specified tender box before the closing date and time stated in the tender notice. Late submissions or those placed in the wrong box will not be considered and will be returned to the tenderer. The envelope must state the tender reference, subject, and closing date and time, but must not bear any mark identifying the tenderer, and must be addressed to the Chairman of the relevant Tender Board.

The three tender boxes are currently located at: Government Secretariat Tender Box (Public Entrance Lobby, G/F, East Wing, Central Government Offices, 2 Tim Mei Avenue, Tamar, for the Central Tender Board), Government Logistics Department Tender Box (G/F, North Point Government Offices, 333 Java Road, North Point), and Works Tender Box (Room 503, 5/F, Low Block, Queensway Government Offices, 66 Queensway). The vast majority of works contracts go into the third one.

There are clear arrangements for severe weather, and the provisions are more precise than commonly understood: if at any time between 9:00 am and 12:00 noon on the closing date, public access to the specified tender box is obstructed, the Government will announce an extension of the closing date and time until further notice; after access is restored, the extended closing date and time will be announced as soon as possible via the Government Information Services press release webpage. In other words, the key is the condition of the access during those three hours, not the whole day; and you must check the press release for the new extended time yourself, do not assume a one-day postponement.

Placing in the wrong tender box and late submission have the same consequence: not considered.

Stage 5: Tender Opening and Evaluation, a phase you cannot see at all

After the closing, the designated tender opening team will open the tenders immediately; only valid tenders will be opened and certified, and the certified originals will be sent to the procuring department for evaluation. The procuring department is responsible for checking compliance with the terms and specifications of the tender documents, and usually recommends the lowest-priced tender that fully complies; if there are other pre-determined evaluation criteria besides price, the most preferable one according to those criteria will be recommended.

This phase is completely blank in public information. Between the closing and the award announcement, OpenTender.hk can only mark the record as closed and cannot show the evaluation progress. The larger the works scale, the longer the blank period, and several months is not uncommon.

A quiet period does not mean there is nothing to do. During evaluation, the procuring department may seek clarification on unclear points in the tender, and engineering contracts must follow the guidelines on clarifying tenders and correcting errors set out in the relevant Development Bureau technical circulars. So keeping communication channels open after tender closing has practical value—if the person handling the project goes on leave and no one takes over responding to clarification requests, that is an avoidable loss.

Another thing that happens during the quiet period is extending the tender validity period. The Civil Engineering and Development Department's Project Management Handbook lists "seeking tenderers' consent to extend the tender validity period" as one of the standard procedures during the tender period; if evaluation drags on, the procuring department will come back to ask whether you agree to an extension. For contracts using a marking scheme, evaluation will also involve a separate evaluation panel specifically assessing the technical part, so it naturally takes longer.

At the same time, note that "closed" does not mean "lost". The Government may re-tender depending on circumstances, for example if all tenders exceed the budget or fail to meet requirements. The Development Bureau has in the past re-tendered conservation and revitalisation projects, and stated that the requirements for re-tendering are the same in all respects as for the first tender. Watch for the same reference number or the same project name appearing again—that is a signal of a second chance.

Stage 6: Tender Board approval—the amount determines who has authority to approve

Tender evaluation recommendations must be submitted to the relevant Tender Board for approval, and each Board comprises not fewer than three members. The tier is determined by amount: the Central Tender Board (chaired by the Permanent Secretary for Financial Services and the Treasury) approves goods and general services exceeding $60 million, and construction services exceeding $200 million; the Public Works Tender Board (chaired by the Deputy Director of Architectural Services) approves public works and related contracts not exceeding $200 million; the Government Logistics Department Tender Board approves amounts not exceeding $60 million; and departmental tender boards approve amounts not exceeding $10 million, but excluding construction and engineering services.

The practical implication for tenderers is the time expectation. A $500 million public works contract must go to the Central Tender Board, and the process is longer than for an $80 million contract handled by the Public Works Tender Board. Any decision to reject a tender must be made by the relevant Tender Board; the procuring department has no authority to reject it on its own.

Stage 7: Award announcement, and what you are entitled to know after losing

Upon approval, the procuring unit will notify the successful tenderer to sign the contract, and will inform unsuccessful tenderers of the tender results and the reasons for their loss. For all contracts awarded in the preceding month, the names of successful tenderers and contract amounts will be published on the internet in the following month—this is the source of information for the contractor directory and award records.

On payment terms, all sums due should generally be settled within 30 calendar days after acknowledgement of receipt of deliverables. Procurement projects launched by the Government on or after 1 June 2025 will adopt electronic payment in full; physical cheques will no longer be provided. Suppliers may receive payment by bank transfer, or through Faster Payment System (FPS) by providing a Hong Kong Identity Card number or an FPS identifier. Projects launched before 1 June 2025 are not affected.

The unsuccessful bidder's "explanation of the reasons for losing" is worth using seriously. It is the only low-cost opportunity to know at which stage you lost: price, technical score, or incomplete qualification documents. Receiving the same type of reason across several contracts usually points to a correctable systemic issue, not luck.

For subcontractors and material suppliers, the award notice is the most useful page on this timeline. The winning bidder's name plus the project name tells you which company will start work in which district over the next year or two, and what type of subcontracting and materials will be needed. This is the point when the contact window is widest—the project team has just been formed and procurement has not yet been locked in.

Turn the timeline into a table you'll actually look at

After understanding the process, the practical question is how to avoid opening a dozen departmental webpages every day. A feasible approach is to divide work by stage, not by department: daily, check only the tender closing countdown (as that is the only page with time pressure); weekly, review the award records (to find subcontracting and supply opportunities); monthly, review the forecasts and EOIs (to handle qualifications and teaming).

The reason for this division is that the decay rates of the three types of information are completely different. Once the tender closing date passes, it becomes permanently invalid; the value of award records can last for several weeks, because the engineering team needs time to be established; the value of forecasts can last for more than a year. Using the same frequency to look at data with three different decay rates will inevitably lead to failure on the most urgent type.

A common mistake is treating the approved list group as a fixed condition. Group A cap HK$150 million, Group B cap HK$400 million, Group C above HK$400 million—if you can only see Group A-scale works for a long time, the point of reading forecasts is to decide whether to prepare for upgrading to Group B works in the next two years, and upgrading requires accumulating suitable project records, which cannot begin only after a tender notice is received.

• Daily: Tender closing countdown (maximum time pressure, invalid upon expiry)
• Weekly: Award records (subcontracting and supply contact windows, value maintained for several weeks)
• Monthly: Forecast and EOI (qualification and teaming, value maintained for over one year)
• Quarterly: Review whether the approved list categories match the project scale you want to bid for

If you feel the process is unfair

Suppliers, contractors or consultancy firms who consider themselves unfairly treated may lodge a complaint with the procuring unit or the approving tender committee / consultancy selection committee. The procuring unit should give a substantive reply within ten working days; if unable to do so, an initial reply must first be given.

Complaints involving breaches of the WTO Government Procurement Agreement and the three free trade agreements with New Zealand, Chile and Australia are handled by the Independent Bid Complaint Adjudication Body established on 30 December 1998, with its secretariat at the Trade and Industry Department. If corruption is suspected, a complaint should be made directly to the ICAC.
