Seismic Retrofitting Of Hospital Building, Kolkata

Problem:

  • 30-years-old RCC hospital building badly affected because of corrosion
  • Building was not qualifying for current seismic code requirement
  • Being important public service building, it was decided to upgrade as per the current seismic code
  • Retrofitting works has to be carried out while hospital is functional

Solution:

  • Exhaustive corrosion repair works were carried out by grouting MCI
  • Polymer modified mortar and micro concrete were used to rebuild damaged section
  • Seismic retrofitting work was carried out by conventional RCC jacketing and FRP wrapping
  • Work is carried out ward by ward by maintaining proper safety and hygiene standard
  • Work was carried out without relocating the patience from hospital

“Sanrachana’s staff was very careful while working inside the hospital. They took utmost care to ensure proper safety and hygiene in the hospital premises while retrofitting” – Matron of Gynecologist ward ESI Hospital, Kolkata

Overview

Ruby Hall Clinic, Pune

Problem:

  • Several locations on the roof slab had to be cut and demolished for medical equipment.
  • This affected the structural behavior of the structural members and slab was sagging.

Solution:

  • Situation was studied and analysis was carried out to device a feasible retrofitting plan
  • Since main reinforcements were cut, compensational tension reinforcement was needed
  • Carbon fiber laminates were applied across the slab width for the same and solved

Overview

Jaslok Hospital, South Mumbai

Problem:

  • 50-year-old RCC structure, needed corrosion repair and strengthening to support new storeys.
  • Strengthening of the foundation and columns was required
  • Hospital needs to be fully functional, thus works can be progressed only on limited area at a time.

Solution:

  • Excavation was conducted after separating the basement into zones
  • Work site was demarcated from interiors by dust-isolating hard plyboard partitions with doors
  • Exposed and new bars were given anti-corrosion treatment and protective coating.
  • Micro-concrete jacketing for the footing, columns and beams
  • Carbon fiber wrapping for beams and columns
  • Migratory bipolar corrosion inhibitor and glass fiber strengthening applied to slabs

Overview

Silchar Medical College Hospital (SMCH)

Problem:

  • The structure was visibly distressed due to ageing
  • Corrosion damage such as spalling and cracking was visible in columns, beams and slabs
  • Rooms in the top floor had leakage and dampness in ceiling, creating threat to sterile environment

Solution:

  • After removal of loose concrete, MCI was applied to protect internal steel.
  • Rust removal and anticorrosion treatment was performed
  • Additional steel was added wherever required
  • Lost sectional area was made up by jacketing in columns and beams
  • Fiber wrapping with SRM G Wrap was done on columns, beams and slabs
  • Terrace level waterproofing coat and screed concrete was applied after removing previous layer and screed
  • External plastering was conducted after touchups and repairs
  • Weather resisting anti-carbonating acrylic based UP protector coat was applied and completed

Overview

STRENGTHENING CANCER THERAPY CENTRE

Problem:

In this prestigious new facility, new storeys were to be built for increasing the capacity.

Diagnosis:

All structural members were found to be in good condition. As per analysis, only columns need to be strengthened. Phase 1 columns could be jacketed whereas Phase 2 columns could not increase in size.

Solution:

  • In phase 1, free-flow micro-concrete jacketing was done after anchoring shear keys and main bars.
  • In phase 2, grooves were made on column, high strength steel plates were anchored on them.
  • Later, surface was levelled with grinding and putty.
  • Carbon fiber wrapping for confinement and strength.
