Supervision and control in the execution phase of the work

Monitoring and coordination for an efficient construction process

The realization of a building project does not end at the design phase: it is during the execution on site that the project takes concrete form and technical, architectural, and plant choices are consolidated. In this phase, characterized by high operational complexity, supervision and control play a fundamental role in ensuring that activities are conducted in accordance with the project documents, current regulations, and required quality standards.

An effective control system does not merely monitor compliance with requirements but is configured as a dynamic process of verification, coordination, and decision-making support. Supervision during the execution phase helps prevent errors, optimize resources, and ensure the safety, quality, and sustainability of the project throughout its entire lifecycle.

Objectives of supervision and control

Compliance with the project and regulations
- Ensure that works are executed according to approved executive documents.
- Verify compliance with building, technical, seismic, fire, and environmental regulations.
Quality control
- Monitor the correct installation of materials and systems.
- Validate the compliance of components with the specifications standards.
Time and cost management
- Compare work progress with the schedule.
- Identify deviations from the budget and adopt corrective actions.
Site safety
- Verify the application of safety measures provided by the Safety and Coordination Plan (PSC).
- Monitor collective and individual protection procedures and devices.
Prevention of variations
- Promptly intercept errors or interferences.
- Propose corrective solutions that minimize costs and delays.

Main activities of supervision and control

1. Document and contractual verification

Analysis of contract documents, technical specifications, and executive drawings.
Control of the conformity of supplies to contractual requirements.

2. On-site inspections

Periodic inspections on the progress status.
Tests and trials on materials (core samples, compression tests, non-destructive tests).
Verification of the correct installation of systems.

3. Management of non-conformities

Detection and recording of discrepancies from the project.
Activation of corrective procedures and tracking of actions taken.

4. Coordination of the workforce

Supervision of activities among different executing companies.
Planning of operations to minimize interferences and downtime.

5. Management of variations and unforeseen events

Technical and economic evaluation of necessary modifications.
Integration of new solutions into the overall project.

Tools supporting supervision

Building Information Modeling (BIM 4D and 5D): monitoring of work progress integrated with time and costs.
Project management software: tools for managing schedules and resources.
Digital checklists: for real-time recording of inspections and non-conformities.
Drones and laser scanners: quick and precise surveys to verify progress and quality of works.
IoT and monitoring sensors: systems for continuous monitoring of structural and environmental parameters during construction.

Benefits of supervision and control

Risk reduction
- Prevention of construction errors and defects that would compromise the functionality and safety of the work.
- Greater legal protection and reduction of disputes.
Economic efficiency
- Lower incidence of variations during construction.
- Accurate cost control and budget compliance.
Quality of the final product
- Works compliant with required standards and more durable over time.
- Better efficiency of systems and energy performance.
Worker safety
- Fewer accidents thanks to continuous monitoring of procedures.
- Creation of a more organized and controlled work environment.
Transparency and traceability
- Complete documentation of inspections and decisions made.
- Greater trust between the client, project management, and executing companies.

Supervision during the execution phase should not be understood as a static verification activity but as a dynamic process of site governance, integrating technical, managerial, and regulatory skills. The ability to adapt to unforeseen events, manage conflicts between disciplines, and ensure continuity of activities becomes a critical success factor.

Moreover, supervision does not end with the completion of the work: it also serves as a reference for testing, maintenance, and subsequent management, thanks to the traceability of the activities carried out and the materials used.

Supervision and control during the execution phase are central activities for the success of any construction project. They ensure consistency between design and realization, guarantee the quality and safety of the work, and contribute to optimizing time, costs, and resources.

Through advanced methodologies, digital tools, and an interdisciplinary approach, supervision is configured as a strategic element to transform a design idea into a concrete, efficient, and sustainable work.

Ultimately, a well-controlled execution phase represents not only a guarantee of quality but an investment in the lasting value of the building and the safety of those who will use it.
