Setting-out report: what it is and when it is signed

The official start of a construction project isn't marked by the arrival of the first excavator or the installation of the site hut. Legally, the clock starts ticking with the signing of a specific document. The setting-out report (acta de replanteo): what it is and when it is signed is one of the most frequent questions when taking on the management of a new project, especially given the contractual and liability implications it carries for the construction company.

In the building sector, this document is not a mere administrative formality. It is the act that formalises the handover of the site to the contractor and validates that what is designed in the execution plans matches the physical reality of the plot. If this step is done poorly, or signed without proper checks, the contractor may inherit project issues that will end up costing both time and money.

What exactly is the setting-out report?

The setting-out report is the contractual and technical document that records that the land is suitable for starting works according to the approved project. During this act, the project management team (architect and building surveyor) and the contractor verify on-site the availability of the land, its boundaries, and the feasibility of the planned foundations.

From a legal perspective, the report serves two main functions:

1. Transfer of possession: The developer hands over possession of the site to the contractor so they can execute the work.
2. Commencement of the execution period: The date of signing is usually what marks "day zero" for the calculation of contractual deadlines. If the contract states the work lasts 12 months, those months are generally counted from the day following this signature.

It is important not to confuse this document with "setting out work packages," which is the daily task of marking axes and levels during execution. The setting-out report is a unique and formal event.

When is the setting-out report signed?

The signature must take place once several prior milestones have been met. A setting-out report cannot be signed if there is no formalised construction contract, no granted building permit, and, above all, if the Health and Safety Plan has not been approved by the safety coordinator.

In private building projects, the usual timing is immediately after the contract is signed and before earthmoving begins. In public works, the law is much stricter and establishes that the Report of Verification of Setting-out must be signed within a maximum period of one month from the formalisation of the contract, unless the tender documents state otherwise.

If you are a site manager, you should never sign this document if you do not have full access to the plot or if you detect affected services (cables, pipes) that do not appear in the project and prevent works from starting immediately.

Differences between public and private works

While the concept is similar, the administrative rigour varies significantly.

In private works (LOE)

This is governed mainly by the Building Management Act (LOE). Here it is often called the "Report of Setting-out and Commencement of Works." It is a more flexible but equally binding document. If the contractor detects that the level points do not match the project topography, they must record this in the report through "reservations" or "provisos."

In public works (LCSP)

Here it is called the "Report of Verification of Setting-out." It is a formal act. If the result of the verification is favourable, the start of the works is authorised. If there are discrepancies that prevent the start, a negative report is drafted, and the execution period is suspended until the contracting authority resolves the issue.

Who must sign the document?

For the report to be valid and have legal effects before the administration and civil liability insurance, it must be signed by:

• The Developer: As the owner of the land and the party commissioning the work.
• The Project Management Team: Composed of the Project Director (Architect) and the Construction Manager (Building Surveyor or Technical Architect). They certify that the project is achievable on that specific land.
• The Contractor: Usually represented by the Site Manager or a company proxy. By signing, the contractor accepts that the land is available and that they are aware of the site conditions.

In some regions or depending on the type of work, the presence of the Health and Safety Coordinator may also be necessary, although their primary signature usually goes on the approval of the safety plan.

Critical aspects to review before signing

A common mistake in small and medium-sized construction companies is viewing the setting-out report as just another piece of paper for the site folder. However, before putting pen to paper, the contractor's technical team should verify the following points:

1. Site availability: Are all access points clear? Is there any illegal occupation or remains of a previous demolition not accounted for?
2. Utility points: Locate the water and electricity connections. If they are not where the project says, the contractor will face cost overruns in time and materials from day one.
3. Levels and boundaries: It is recommended that the contractor's surveyor performs a quick check of the plot vertices. If the plot is smaller than stated in the project, the building might not fit or might breach municipal setback requirements.
4. Condition of adjacent buildings: If there are party walls or attached buildings, the setting-out report is the time to mention if there are pre-existing cracks or pathologies that could be blamed on the work later.

Minimum content of the report

Although there is no single universal template, any professional setting-out report must contain:

• Place and date of the act.
• Identification of the project and the municipal license.
• Identification of the parties involved.
• Express declaration that the project management team has carried out the setting-out of the perimeter and main axes.
• Record of the existence of the approved Health and Safety Plan and the Site Diary (Instruction Book).
• Reference to the feasibility of the project on the ground.
• Observations or reservations (if any).
• Express authorisation for the commencement of works.

Digital management of site documentation

Keeping track of all these reports, along with contracts and scheduling, is often a chaos of shared folders and emails. Nowadays, many companies use specialised software to centralise this information.

There are very powerful market options. For example, Presto is a standard for budgets and bills of quantities, while Procore offers robust document management for large international projects. In a segment more focused on construction SMEs seeking simplicity and cost control, Constrack allows for the digitisation of all document management, ensuring that reports like the setting-out report are always accessible to the site manager and management from a mobile device, linking them directly to the project's bill of quantities.

Digitising this process avoids the typical problem of: "where did we keep the original setting-out report we signed eight months ago?" when a delay claim arises.

What happens if there are errors in the setting-out?

If, after signing the report without reservations, it is discovered that the ground has a different geological composition than the geotechnical study, or that the actual dimensions prevent the planned foundation from being executed, the contractor finds themselves in a weak position.

By signing the report, the contractor acknowledges that the project is "constructible." If there are serious undetected errors, this usually leads to a project modification. In public works, if the error forces a modification exceeding 10% of the budget, the process can become administratively complicated to the point of halting the work for months.

Therefore, if the site manager detects any anomaly, they must include a "reservation" in the report. A reservation is a note indicating that, although the land is received, it is recorded that a discrepancy exists which could affect the cost or the deadline.

The importance of the report for civil liability insurance

Insurers issuing Decennial Insurance (mandatory for housing in Spain) or the contractor's Civil Liability insurance usually request a copy of the setting-out report. For them, it is proof that the work began under the supervision of the project management team.

If an incident occurs during the foundation phase and there is no signed setting-out report, the insurer might try to evade liability by claiming that the work began irregularly or without the necessary technical validation.

Conclusion

The setting-out report: what it is and when it is signed is not just an administrative milestone, but the contractor's most important legal protection at the start of the works. It defines when you start being responsible for what happens on that plot and when your deadline to hand over the keys without penalties ends.

For a site manager, the day of setting-out is the time to be meticulous. It is not about creating obstacles, but about ensuring that the base upon which you are going to build — the land and the project — are consistent with each other.

Maintaining rigorous control of these signatures and all technical documentation is much simpler when you move away from paper and scattered spreadsheets. If you manage a construction company and want to have all your sites, budgets, and documents under control in one place, you can try tools designed specifically for the sector.
