APE SISMICO supports bridge owners, consultants and contractors with site assessment, repair planning and rehabilitation execution. Our service scope covers bearings, expansion joints and concrete components, together with architectural expansion joint work.
We begin with the condition of the structure and the project requirements. Inspection findings, relevant testing and access constraints help define the proposed intervention and the information needed for a detailed project report.
Establish the condition of the structure and the basis for a proposed intervention.
Repair and replacement activities for components and structural areas identified through assessment.
Assessment and execution support for building expansion joint systems.
Effective rehabilitation starts with understanding how the structure is performing and where deterioration has occurred. Our service activities cover bridge components and concrete repair, with the proposed intervention developed around the site conditions.
Condition-led interventions to support the continued service of existing infrastructure.
Maintenance planning begins with identifying deterioration, understanding its cause and selecting the appropriate intervention. Bearings, joints and surrounding concrete are considered together when defining the work.
Addressing defects at an appropriate stage can help limit the extent of later repairs. Inspection findings provide a basis for prioritising work and planning resources.
Documented condition assessments help bridge owners and engineers identify defects, consider operational constraints and determine the required response.
A planned approach to component maintenance and rehabilitation helps manage deterioration throughout the service life of the structure.
The photographs illustrate existing deterioration and stages of repair. The repair method, materials and sequence are defined for the individual structure.
Visible deterioration includes spalling, cavities and delamination in the beam. Assessment of damaged concrete and previous repairs informs the rehabilitation scope.
The illustrated work includes removal of damaged concrete, cleaning and attention to reinforcement before rebuilding the affected section.
This stage illustrates rebuilding damaged areas and filling cavities using the materials specified for the rehabilitation work.
Formwork is arranged around the affected beam area as part of the repair sequence.
The photograph records the repaired beam following the illustrated rehabilitation stages.
Replacement work addresses the joint assembly and its connection to the existing deck. Site dimensions and surrounding concrete conditions are part of the technical review.
The illustrated sequence includes removal of the damaged joint, installation of the replacement assembly and reinstatement of the surrounding deck interface.
Bearing replacement is coordinated with the support arrangement, lifting requirements and rehabilitation of the bearing seat. The photographs show stages of the recorded work.
The existing bearing and support area are documented before the replacement work.
The photograph illustrates the lifting stage undertaken to provide access to the bearing position.
The replacement bearing is installed with repair of the adjoining bearing seat as shown in the project photographs.
Grouting ports are positioned for treatment of the repair area within the rehabilitation sequence.
The illustrated work records grouting using the equipment selected for the repair operation.
