Construction supervision

Construction supervision and technical verification

Construction supervision follows the works on behalf of the client: it seeks to ensure the design, the contract and good building practice are followed, that deadlines hold, and it helps analyse the changes, setbacks and decisions the works bring. Technical site monitoring, execution verification, reporting and document management in building works, refurbishment and technical (MEP) installations, up to provisional acceptance, with scope defined for each project and periodic site visits at the frequency set out in the proposal.

What we do

Full technical supervision

We cover the entire construction cycle, from first-fix infrastructure to provisional acceptance.

Building works and refurbishment

Refurbishment, waterproofing, insulation, roofs and terraces: we check each layer before it is covered. We monitor the construction and demolition waste prevention and management plan (PPGRCD), where required, and waste handling on site.

Technical installations (MEP)

HVAC, domestic hot water, electrical, telecommunications and fire safety, from first-fix to installation.

Compliance verification

We check that materials, equipment and execution methods comply with the design and the specifications.

Quality control

We verify execution quality at every stage, from substrate to final finishes.

Change management

We review contractors' change proposals and give a technical opinion to the Owner, who decides, assessing the technical, regulatory and financial impact. We also give a technical opinion on additional works and on errors and omissions.

Schedule control

We check and validate the contractor's work plan, time schedule and financial schedule, and monitor progress of the works against the schedule, identifying deviations and proposing corrective action.

Tests and inspections

We require, oversee and validate all tests set out in the specifications and applicable regulations, such as watertightness tests.

Document management

Material approval sheets, photographic records, measurement reports, test sheets, as-built drawings and the organisation and validation of the technical file of the works.

Meetings and reports

We chair site meetings, with minutes, and send the Owner a monthly progress report.

Measurements and final account

We validate measurement reports with an opinion from the Supervision team. Payment is approved by the Owner. We support the closing of the final contract account.

Site safety coordination

Associated service, when contracted, under Decree-Law 273/2003: review of the safety and health plan and scheduled visits.

Our process

Present at every critical stage

Supervision begins before construction starts — and ends with the complete documentation handed over to the client.

01

Supervision planning

We review the design and specifications, and define the critical inspection points and acceptance criteria for each type of work, and monitor the handover of the site to the contractor.

02

Substrate and first-fix

We check the substrate, falls and waterproofing, as well as drilled openings, blockouts, cable routes and embedded pipework before ceilings and walls are closed — the most critical stage.

03

Execution and installation

We check the execution of insulation, roof and terrace layers, check that the equipment received complies with the design and validate the installation of HVAC units, panels, racks and fire alarm control panels.

04

Testing and commissioning

We oversee all tests: tightness of roofs and terraces, pressure, electrical measurements, fire-detection testing and cabling certification.

05

Provisional acceptance

We prepare punch lists, follow up on defect resolution and validate provisional acceptance with all technical documentation compiled.

06

Warranty period and final acceptance, on request

The warranty period and final acceptance are included only at the client's express request.

FAQ

Frequently asked questions about construction supervision

What does construction supervision do?

It follows the works on behalf of the client: site visits, checking execution against the design and specifications, quality control of materials and works, checking measurements before each payment, following tests and reporting regularly to the client.

Is construction supervision mandatory?

For works that need a licence or prior notification at the municipality, the file includes the statement of responsibility of a construction supervision director, a technician qualified under Law no. 31/2009. For other works, supervision is the client's choice to follow quality, deadlines and costs.

How much does construction supervision cost?

It depends on the size and type of building, the scope required and the level of detail. We prepare the proposal after receiving the documents (design, expected schedule and required scope), to make sure what we propose fits what you need.

What is the difference between supervision and site management?

Site management belongs to the contractor and organises who builds. Supervision works for the client and checks whether what is built follows the design, the contract and good practice. That is why supervision is hired by the client, separately from the contractor.

Do you supervise small works, such as a home renovation?

Yes. We follow home renovations, office and retail buildings. On small works, supervision can focus on the critical moments: before walls and ceilings are closed, during installation tests and at handover.

Where do you work?

Across Portugal. Afazeres Curiosos is headquartered in Mafra.
