Unfinished Construction Site: The Contractor Walked Off the Job

The workers stop coming back. Calls go unanswered. The project, started weeks or months ago, sits frozen halfway through: openings left unclosed, utilities unconnected, flooring waiting for finishing work. This is one of the most stressful situations a client can face, both technically and financially, because the house or flat is often left uninhabitable or exposed to the elements.

The pain: a stalled site, a home left exposed

Site abandonment is unfortunately a situation we encounter regularly in expert assessments around Antibes and more broadly across the Provence-Alpes-Côte d’Azur region. It doesn’t necessarily involve a dishonest contractor: cash-flow trouble, disputes with the client over extra work, poor organisation, or genuine disappearance can all be the cause. What stays constant is the urgency: structural work left open to the weather, a partially removed roof, or a dangerous electrical installation left unfinished all expose the property to rapid deterioration and, at times, safety risks.

The client is left facing several urgent issues at once: protecting the building from further damage, working out what is still owed – or not – to the defaulting contractor, and arranging for another firm to take over the site without paying twice for the same work.

Why this happens

Legally, abandoning a site is a serious breach of the contractor’s obligations, who is required to carry out the work through to completion in line with the contract (Article 1103 of the French Civil Code). In practice, several factors often trigger this situation: a dispute over extra work not included in the original quote, with the contractor halting the site until that work is paid separately; the contractor’s cash flow being strained by other ongoing jobs that absorb the available workforce; or an initial underestimate of the project’s complexity that discourages the contractor from continuing at a loss.

It’s worth noting that clients themselves sometimes suspend payments mid-project in reaction to defects or delays they’ve observed. This can be legitimate, but it must be done carefully: an unjustified payment suspension can be reclassified as a breach by the client, giving the contractor grounds to justify stopping work.

What can be done

The first priority is to secure the building if needed, particularly where structural work is exposed to the weather: tarping, temporary enclosure, and making the electrics safe. If this emergency work is invoiced by another company, it must be documented precisely, as its cost can later be claimed back from the defaulting contractor.

Next, a formal notice should be sent to the contractor requiring them to resume the work, by registered letter with acknowledgement of receipt, setting a reasonable deadline for doing so. If there is no response or no actual resumption of work, this formal notice allows the contract to be terminated at the contractor’s fault, under Article 1224 of the French Civil Code on termination for non-performance. This formal termination is essential before bringing in a new contractor – otherwise the client risks double billing or later disputes over how responsibility is shared.

Regarding sums already paid to the defaulting contractor relative to actual progress on site, it is strongly recommended to have a precise assessment of the work completed drawn up before any new contractor takes over. This assessment establishes whether sums have been overpaid relative to the work actually carried out – a common practice being to invoice a higher percentage of completion than is real – which entitles the client to reimbursement. Conversely, it also confirms what remains owed, protecting the client from a later legitimate claim by the contractor.

How the expert helps

In this type of situation, our work involves drawing up a dated, joint assessment of the site’s actual progress at the point it was abandoned: which items from the quote were actually completed, to what extent, at what quality level, and what remains to be done. This assessment, cross-checked against the original plans and quote, allows us to precisely quantify the gap between sums paid and the real value of work carried out.

We also assess the condition of work in progress to detect any defects that appeared before the site was even abandoned, preventing them from being mistakenly attributed later to the new contractor taking over. This report is a key negotiating document with the defaulting contractor, a solid basis for potential court proceedings, and a reference document for drawing up a new, coherent quote for resuming work, without duplication or omission. With fifteen years of experience in public works and project management, we know how to assess a site mid-construction – a different skill from assessing a finished building.

Frequently asked questions

Can I bring in another contractor straight away?
It’s recommended to formally terminate the contract with the defaulting contractor before any new firm takes over, to avoid disputes over how responsibility and payments are shared.

How do I know if I’ve overpaid relative to actual progress?
A joint technical assessment allows a precise comparison between the sums paid and the real value of the work carried out under the original quote.

Can the contractor still claim a balance despite abandoning the site?
If the work carried out exceeds the sums already paid, a claim remains theoretically possible – which is why a precise assessment is essential to establish the facts objectively.

Should I wait before securing an abandoned site?
No, securing the building (against weather, electrical risks) is an urgent matter that should be dealt with immediately, regardless of ongoing contractual steps.
