Railways and Tramway

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, 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.
