Roads and Highways
Wide experience in feasibility studies and detailed design in the field of roads, highways and railways (high speed train, metro and light rail).
Feasibility studies: analysis of the technical, functional, environmental, social and economic viability of the works, as well as the previous design of the selected solution.
Detailed design: final design of the solution previously selected.
These works include the specialties of: geology, geotechnics and earth works; climatology, hydrology and drainage; design of tunnels and viaduct; compulsory purchase and replacement of affected services; temporary and permanent signposting; environmental impact assessment; planning; technical prescriptions; budget.
Wide experience in site supervision in the field of roads, highways and railways (high speed train, metro and light rail).
Tasks before the execution of the works
- Design study and analysis.
- Analysis of the contractor’s technical proposal and the contract.
- Analysis of the quality assurance plan and establishing the control supervision plan.
Tasks during the execution of the works
- Checking the soil, materials and equipment.
- Control of the execution of the works and contrast tests.
- Financial control of the project and the work schedule.
- Monthly project reports and non-conformities.
- Management of affected services and compulsory purchases.
- Control of items to be justified and design modifications.
Tasks for the acceptance and payment of the works
Project documentation management
- Monthly and one-off reports.
- Correspondence and minutes of meetings.
- Final project report and as-built drawings and plans.
Since 1992 OFITECO is able to provide technical assistance in quality control in the following fields:
- Tests of soils, bituminous surfacing and other materials in road.
- Tests on binders, aggregates, water, concrete, grout, precast elements and self-compacting concrete.
- Signage and traffic control equipment.
- Geotechnical surveying tests.
- Weld monitoring tests in steel.
- Tests of engineering and masonry structures.
- In-service tests.
Fieldwork
OFITECO has equipment and qualified personnel to monitor:
- Earthmoving and road surfaces. Taking of samples, compaction monitoring (in-situ density and plate bearing).
- Concrete structures. Monitoring fresh concrete, non-destructive tests (ultrasounds, scelerometer, crosshole tests in piles), extraction of cores.
- Steel structures. Weld monitoring (ultrasounds, magnetic particles and liquid penetrants).
- Signage. Monitoring horizontal and vertical signage (back reflection, chrome coordinates, etc.).
- Instrumentation. Installation and reading of inclinometers and settlement lines.
Monitoring, assistance and audit of:
- Quarries.
- Concrete plants.
- Precast plants.
- Plants for producing asphalt mixes.
These operations concern the maintenance engineering and the structures management areas of, both roads and railways.
- Analysis and diagnostic, remedy implementation and follow-up are the main stages of the following specific tasks:
- Routine, main and special inspections.
- Instrumentation.
- Loading tests for approval or assessment of the carrying capacity, and tests with research purposes.
- Structures repair, reinforcement and adaptation projects.
- Maintenance planning and permanent monitoring.
