Structural Audit and Retrofitting Design


Structural Audit and Retrofitting Design

Structural Audit is an engineering assessment of existing buildings to monitor their structural health. Audits are carried out for various reasons:

When Visual Deterioration such as Cracks & Corrosion are seen

Assessment for Seismic Preparedness
  • Old structures not designed for earthquake forces
  • Loss in Seismic Capacity due to deterioration

Assessment due to increase in loading
  • Addition of floors in a building
  • Addition of rooftop telecom towers/water tanks
  • Increase in crane capacity for industrial plants
  • Addition of equipment / manufacturing lines in industrial plants

Assessment due to change in use (for e.g. from industrial to commercial)

Assessment due to change in owner - for making pre-purchase decision

Periodic Health Monitoring
  • Visual Assessment
  • Non-Destructive Testing
  • Identify members where repairs / retrofitting is required
  • Decide repair/retrofitting methodologies
  • Prepare Bill of Quantities & Budgetary Cost Estimates
  • As-Built Drawing Preparation
  • Structural Drawing Preparation using Rebar Mapping
  • Visual Assessment
  • Non-Destructive Testing
  • 3D modeling & software analysis of structure
  • Check strength of each structural member (beams, columns, slabs etc)
  • Identify members where retrofitting is required
  • Design Retrofitting Solutions
  • Prepare Bill of Quantities & Budgetary Cost Estimates
  • Preparing Bid Documents including Technical Specifications
  • Invite bids from reputed repair contractors
  • Negotiations with Contractors
  • Quality Control at Site
  • Safety Management
  • Keeping Costs within control
  • Checking and Approving Contractor’s Running Bills
  • Prepare snag list for rectification by contractor
  • Reconcile and approve final bills of contractor
  • Obtain all warranty certificates and hand over to client
