Retrofitting & Strengthening

Strengthen Existing Structures. Improve Performance. Extend Service Life.

Pronomina Engineers provides retrofitting and structural strengthening solutions for existing buildings and infrastructure requiring repair, rehabilitation, improved load capacity, or performance upgrades. Our approach emphasizes engineering assessment, suitable strengthening methods, controlled execution, and quality verification in accordance with approved project requirements.

Depending on the project’s needs, the scope may include concrete and steel strengthening, column and beam jacketing, structural repairs, foundation strengthening, and other engineered interventions. Each solution must be selected following an appropriate technical assessment and approved design.

Retrofitting & Strengthening

CORE SERVICES

  • Review of available structural drawings and previous repair records
  • Visual inspection and documentation of observed defects
  • Identification of areas requiring further investigation or testing
  • Coordination with qualified structural engineers
  • Planning of remedial work based on approved recommendations

Strengthening of reinforced concrete columns through an engineered jacketing system where specified by the approved design. Depending on the assessment, this may involve additional reinforced concrete, steel jacketing, or another suitable strengthening solution.

Work may include surface preparation, reinforcement installation, formwork, concrete or grout placement, connection detailing, and inspection.

  • Reinforced concrete section enlargement
  • Steel plate or steel member strengthening
  • Fibre-reinforced polymer (FRP) systems
  • Approved supplementary support systems
  • Localized repair and strengthening of deficient areas

Strengthening of suitable steel members and connections through engineered modifications such as additional plates, stiffeners, supplementary members, or connection upgrades.

Work is planned around the existing member condition, connection accessibility, load-transfer requirements, and approved welding or bolting procedures. Temporary support and load restrictions may be necessary during intervention.

Application of fibre-reinforced polymer systems, such as carbon or glass fibre composites, where suitable for the existing substrate and approved strengthening design.

FRP systems may be considered for selected beams, columns, slabs, and other structural elements. Surface preparation, substrate strength, environmental conditions, anchorage details, and installation procedures are critical to system performance.

Engineered interventions for existing foundations where investigations identify settlement, changes in loading, inadequate bearing performance, or other foundation-related concerns.

Depending on site conditions and design requirements, possible solutions may include foundation enlargement, underpinning, supplementary piles, or other approved measures. Geotechnical investigation and structural coordination are essential before selecting a method.

Repair of deteriorated concrete and damaged reinforcement as part of an approved structural rehabilitation plan.

The work may include removal of unsound concrete, assessment and treatment of reinforcement, replacement or supplementation of reinforcement where designed, application of compatible repair materials, and protective treatments where specified.

Strengthening interventions intended to improve the seismic performance of existing structures where required by an engineering evaluation and approved design.

Depending on the structural system, potential measures may include column and beam strengthening, joint strengthening, addition of engineered bracing or structural walls, and improvements to selected connections or load paths.

Coordination of strengthening work for buildings undergoing changes in occupancy, equipment installation, additional floor loading, or other proposed changes that affect structural demand.

Any proposed increase in load or change in building use must be reviewed by the responsible structural engineer before construction begins.

Retrofitting Execution Process

Structural retrofitting may be required due to ageing, deterioration, changes in building use, increased loading demands, construction defects, seismic performance requirements, or damage caused by environmental and operational conditions.

Why Choose

Pronomina Engineers?

Engineering-Led Approach

Strengthening solutions should be based on documented site conditions, appropriate investigation, and an approved design rather than assumptions.

Method-Specific Execution

Work planning considers the selected strengthening system, substrate condition, installation requirements, and interaction with existing structural elements.

Quality-Focused Delivery

Defined inspection points and material verification support compliance with the approved method and project specifications.

Coordinated Site Management

Retrofitting activities are planned around access, building occupancy, temporary support, MEP systems, and other construction operations.

Safety-Conscious Planning

Structural interventions require careful work sequencing, controlled access, and appropriate precautions to protect workers, occupants, and adjoining property.
