Construction HSE Coordinator: When It Is Mandatory, 2025 Amendment, and Cost

When you manage a construction project as an investor, developer, or municipality, your main focus is on deadlines, budget, and subcontractors. Safety often remains in the background until an inspection by the labor inspectorate occurs or an accident happens on site. A construction HSE coordinator, however, is not a bureaucratic formality. It is the person who holds the safety system together when multiple companies are present on one site, each with their own working methods.

This text summarizes when a construction HSE coordinator is mandatory, what changed with the 2025 amendment, what the HSE plan entails, and what factors determine the cost.

If you are dealing with a broader safety setup on the construction site—responsibilities of the client and contractors, documentation before site handover, and typical inspection findings—a separate overview follows: Construction HSE: obligations, HSE plan, and inspection preparation.

When Is a Construction HSE Coordinator Mandatory

The obligation arises under Section 14 of Act No. 309/2006 Coll. when employees of more than one contractor will be working on the site. The client (investor) is then obliged to appoint in writing one or more coordinators, considering the type, size, and complexity of the construction. The coordinator is appointed for both phases: during construction preparation (from the processing of project documentation) and during realization (from the handover of the site to the first contractor until the completed construction is handed over).

It does not matter whether it is a large development project or a renovation of a municipal office. Two or more contractors on one site mean a coordinator is mandatory.

The most common misconception is that all coordination obligations are triggered simultaneously by a single number. In reality, these are three different things, each with its own condition—and when they are confused, something is either done unnecessarily, or conversely, is missing:

The notification of work commencement is sent by the client to the regional labor inspectorate no later than 8 days before the site handover. The HSE plan is developed by the coordinator.

The decisive factor is the actual number of contractors and their employees on the site—including subcontractors. The employees of a subcontractor are employees of another contractor, so if they work on the site alongside the general contractor’s people, the condition of multiple contractors is met—even when the subcontracts are managed by a single general contractor. Therefore, it is not who organizationally manages whom, but how many contractors are actually present on the site.

When a coordinator is not appointed. The law has exceptions. A coordinator is not appointed for work the builder carries out for themselves on a self-help basis, for constructions not requiring a project permit under the Building Act, and for listed technical infrastructure networks (low-voltage electrical power, gas up to 4 bar, electronic communications). However, borderline cases should be assessed individually, not by guesswork.

What Changed with Amendment No. 318/2025 Coll.

The Act on Ensuring Further Conditions of HSE was amended by Act No. 318/2025 Coll. with phased effectiveness from the end of 2025 (the last part from 1 January 2026). The amendment strengthened the role of the coordinator on the construction site. The law now explicitly states that the coordinator, throughout their appointment, coordinates cooperation between contractors (including those who alternate on the site), their mutual awareness of the current progress of work and adopted measures, and continuously briefs them on the plan and its updates. The amendment also binds the coordinator to confidentiality. Contractors, in turn, have an explicit duty to implement the measures set by the coordinator and to require their implementation by others as well.

The coordinator now has the authority and obligation to order a cessation of work if there is an imminent threat to life or health; they inform the site manager immediately about the cessation. The HSE plan itself no longer requires the signatures of individual contractors.

In practice, this means one thing: the coordinator’s role is no longer just a “paper” role. The labor inspectorate monitors whether the coordinator is actually coordinating and whether contractors are implementing their measures.

Preparation and Realization: Two Phases, Occasionally Two People

Coordination does not only happen with the first shovel. The law recognizes two phases, which can be covered by one person, but also by two different specialists—and each has a different scope of work.

In the preparation phase, the coordinator steps in before work begins. They develop or arrange for a construction site HSE plan, coordinate the schedules of individual contractors regarding safety risks, assess the project documentation from a safety perspective, and alert the client to areas requiring measures. The outputs are the HSE plan and the safety requirements the coordinator sets for each contractor.

In the realization phase, the coordinator works throughout the duration of the work on site. They check compliance with the HSE plan, monitor the concurrence of activities of different companies, convene inspection days, and propose measures where risks intersect. However, they do not replace the competent persons of individual contractors—each company remains responsible for its own employees. The coordinator exclusively deals with issues arising from the co-action of multiple entities in one place.

A special and unpleasant case is deploying a coordinator only during ongoing construction—typically after an inspectorate inspection or an accident. While coordination is formally supplemented this way, the coordinator takes over a space in progress with limited knowledge of what happened on the site before their arrival, and the client has already been operating outside the legal framework. Retroactive provision is usually more expensive and documentation is more complicated than timely appointment.

What the Coordinator Addresses—and What Remains with the Contractors

The boundary of the coordinator’s role is the source of most disputes on site. The coordinator is not a superior to the site manager, nor an inspector who would take over safety for individual companies. They monitor points of collision: where crane movement meets people, where temporary electrical installations run, how openings, edges, and escape routes are secured, and how interdependent activities that interfere with each other are sequenced.

What the coordinator is not responsible for are revisions and inspections of technical equipment belonging to individual contractors. Responsibility for site switchboards and temporary electrical installations lies with whoever brought them to the construction, for scaffolding with its supplier, and for machinery with its operator. The revision of a site switchboard is thus the obligation of the specific company, not the coordinator—they only ensure that risks from this equipment do not affect others; how such a switchboard revision is conducted is described in a separate article.

The Difference Between the HSE Plan and Coordination

These two terms are often confused, but they are two separate things that build on one another.

The construction site HSE plan is a document. It is drafted by the coordinator before work begins. It contains specific rules for the given construction: initial training, accident reporting procedures, fire safety measures, rules for storing chemical substances, definition of hazardous work, and inspection schedules. It must be available to all contractors.

HSE coordination is the actual performance of activities during construction. The coordinator visits the site, checks compliance with the plan, convenes coordination meetings, highlights risks, and communicates with foremen and site managers.

Simply put: the plan is a document, coordination is on-the-ground presence. Both are necessary.

Documentation: Site Log and Coordinator Outputs

The coordinator keeps written documentation of their activities, and it should be available directly on the construction site. The most practical approach is to record findings in the site diary—this eliminates the risk of the document getting lost, and all parties have immediate access to it. An entry only makes sense when it contains the date, a description of the identified deficiency, a proposed measure, and a deadline for correction; formal or missing entries are evaluated by the inspectorate as a failure to fulfill the duty.

In addition to the diary, the coordinator’s outputs typically include:

• The construction site HSE plan, including all updates,
• Records from inspection days and coordination meetings,
• A summary of risks and measures arising from the co-action of multiple contractors,
• Proof of information transfer between the outgoing and incoming contractor.

All these documents should be physically available on site. The argument that they are “at the company’s headquarters” does not hold up during an accident investigation—both the inspectorate and the police check their availability directly on site. Moreover, the HSE plan is not a one-off document: in case of a significant change in the scope or work schedule (new contractor, technology change, deadline extension), the coordinator updates it; otherwise, it becomes an outdated—and practically missing—basis during an inspection.

How to Recognize a Good Coordinator

The law requires the coordinator to be professionally competent. Prerequisites are set out in Section 10 of Act No. 309/2006 Coll.: at least secondary education with a final examination, appropriate professional experience, and a successfully passed exam of professional competence, which must be periodically renewed. But this is just a ticket—a certificate says nothing about the coordinator’s quality. In practice, you can recognize a good one by several specific signs:

• During the initial inspection, they look mainly at points of collision. They watch where the crane meets pedestrian movement, where temporary installations run, how openings and edges are secured. A general walk through the site without focusing on specific risks is a sign of a formalist.
• Inspection records have a deadline and a responsible person. Not “tidiness needs to be improved,” but “Contractor A will clear rubble from the escape route on the 1st floor by Friday, the site manager is responsible.” An entry without an addressee and a deadline is just a statement.
• The HSE plan is not a copied template. It contains specific risks of the given construction—work at height during roof structure assembly, interference with existing utility networks, concurrence with the warehouse operation of an adjacent hall. A document without a single mention of the specific characteristics of the construction is a signal of poor quality.
• Communicates actively, not just via email. They know the schedule well enough to point out a future collision before it happens and deal with matters operationally with the site managers.

What to Provide for Quick Pricing of an HSE Coordinator

When you request an HSE coordinator for a construction project, the fastest pricing comes when it’s clear how much risk and how much work the coordination actually entails. Without basic documents, only an indicative range can be given, which can vary by tens of percent:

• Scale of the construction – floor plan, number of floors, enclosed volume, length of a linear construction.
• Expected construction duration – in months, ideally a schedule.
• Number of contractors – how many companies will be working on site simultaneously.
• Nature of the construction – new build, renovation during operation, demolition, work at height, work with cranes.
• Frequency of inspections – daily presence, or 2–3 visits per week.
• Whether you already have an HSE plan – if not, it needs to be accounted for separately.

If you are unsure whether the coordinator obligation has already arisen, send us at least a basic description of the construction, the number of contractors, and the expected realization date. We will tell you whether you need to address the coordinator, the HSE plan, the notification of work commencement, or just supplementing documentation before an inspection.

Schedule: When to Secure a Coordinator

The most common mistake made by clients is not that they forget about the coordinator—but that they address them too late. A quality HSE plan requires studying the project, physically inspecting the site, and communicating with contractors, and this cannot be accomplished in a few days. A reasonable timeline looks like this:

1. During the project documentation phase. Involving the coordinator early in the preparation phase means their comments on realization risks are incorporated into the project—preventing costly changes during construction.
2. During contractor selection. The coordinator can assess the safety documentation of bidders; a company that cannot provide its own HSE system is a risk to the smooth progress of the construction.
3. Sufficiently in advance of site handover. At this point, the coordinator should be appointed and have the complete construction documentation available; the HSE plan should be finished before work begins on site.

Approaching a coordinator a week before the first company starts and expecting an HSE plan “immediately” is therefore a recipe for a formal document that protects no one. For proper preparation, it is reasonable to think in terms of weeks rather than days.

Risks of a Late Solution and Inspection by the Inspectorate

The most common mistake: the investor starts addressing the coordinator only when the first subcontractors are already working on site. This brings specific risks:

• Fine from the labor inspectorate. Compliance with obligations regarding coordination is checked by the State Labor Inspection Office through regional inspectorates. For offenses related to occupational safety, Act No. 251/2005 Coll. allows for significant fines to be imposed; the specific amount depends on severity and consequences, and the upper limits of penalties changed with amendments from 1 January 2026, so it is appropriate to refer to the current version of the law. Both the client for failing to secure a coordinator and the coordinator themselves for failing to fulfill their duties can be penalized.
• Stoppage of work. An inspector can order the cessation of work until a remedy is made. Every day of downtime costs money.
• Unclear responsibility in case of an accident. Without a coordinator and a plan, it is harder to prove who was responsible for what. Insurance payouts can be reduced according to agreed policy conditions if a breach of duty is proven.
• Chaos in documentation. Each subcontractor keeps their own HSE agenda; without coordination, an unintelligible mess arises that will not hold up under inspection.

Inspectors have the right under Act No. 251/2005 Coll. to enter the construction site during working hours without prior notification and check whether a coordinator has been appointed, whether the HSE plan exists, and whether it is being followed. How such an inspection proceeds and what it focuses on is detailed in the article Labor Inspectorate Inspection.

It is worthwhile to address the coordinator ideally in the design phase for the building permit, and at the latest before the site is handed over to the first contractor. Timely appointment usually costs less than additional catch-up on the plan, missing records, and corrective measures when the construction is already underway.

When the Coordinator Is Not Mandatory—and Yet It Is Worthwhile

Even when the obligation does not arise, a coordinator can be worthwhile. A typical case is the renovation of a production or storage hall during operation: the concurrence of construction with normal operations creates risks that exceed the scope of individual site managers. An external coordinator covers them across operations and contractors—and as an outsider, they are not perceived as someone who “checks from the employer’s position.”

Similarly, when several small suppliers work without a general contractor—when the investor separately contracts an electrician, floor layer, and painter for one renovation. None of them is responsible for the others, and the coordination role would otherwise have to be performed by the client themselves.

How Much a Construction HSE Coordinator Costs

The price of an HSE coordinator always depends on the specific parameters of the construction. There is a difference between a short renovation with a few visits and a long construction where dozens of subcontractors alternate and hazardous work regularly occurs. The costs are borne by the client; they can only be transferred to the contractor through a contractual arrangement, and the primary responsibility still remains with the client. Take the following data as indicative.

Construction site HSE plan – a one-off document. Indicatively from CZK 8,000 for smaller constructions to CZK 30,000 and more for extensive or high-risk projects.

Coordination performance – a repeated activity during construction. Most often charged as:

• hourly rate per visit (indicatively CZK 500–900/hour),
• monthly flat rate according to inspection frequency (e.g., 2× per week indicatively CZK 8,000–15,000/month),
• a lump sum for the entire construction period for smaller constructions with a clear schedule.

The price is increased by daily presence, a high number of subcontractors, work at height and with cranes, renovations during operation, and a fast schedule. For large and risky constructions, the coordinator is practically on site full-time, and the monthly cost corresponds to that—the decisive factor is not only the number of contractors but the nature and risk level of the work.

For a reasonable business offer, it is important to set the coordination to match the actual operation of the construction. For smaller projects, an HSE plan and regular inspections at key stages may suffice. For more complex constructions, a fixed regime of inspections, coordination records, and a clear connection to the site manager or the investor’s technical supervisor makes sense.

Frequently Asked Questions

Do I need a coordinator even when building a family house on a self-help basis? No. If you build as the builder on a self-help basis and employees of no more than one contractor are working for you, the obligation does not arise (the law explicitly exempts this situation). However, once you involve several companies simultaneously, the obligation is triggered.

Who pays for the coordinator? The client (investor). Costs can be contractually transferred to the general contractor, but the responsibility for appointing the coordinator remains with the client.

Can the coordinator also be the site manager? The law does not directly prohibit it, but we do not recommend it in practice. The site manager is pressured by deadlines and production, while the coordinator must guard safety. Combining roles reduces the effectiveness of control.

What if I don’t appoint a coordinator and an inspection comes? The labor inspectorate can impose a fine and, moreover, order the cessation of work; the amount of the penalty is assessed according to the severity and consequences under the current wording of the Labor Inspection Act. After the 318/2025 amendment, the inspectorate also monitors whether the coordinator is actually coordinating.

Is an HSE plan sufficient without a coordinator? No. The plan must be put into practice by someone and its compliance must be checked. Without a coordinator, it is just a document in the site cabin. The inspectorate checks not only the existence of the plan but also its fulfillment.
