A technical assessment by the Department of Civil Engineering at IIT Madras has identified serious structural and waterproofing deficiencies in Goa's iconic Kala Academy building, raising concerns over the condition of the recently renovated cultural landmark.

The findings are part of a report submitted to the Goa government following a site inspection conducted by experts from the National Centre for Safety of Heritage Structures at IIT Madras. The visit was undertaken through the Charles Correa Foundation (CCF) at the request of competent authorities.

Kala Academy, a premier cultural institution established in 1970 and designed by celebrated architect Charles Correa, underwent extensive renovation in recent years. However, the restoration project had already drawn criticism over alleged defects and concerns regarding preservation of the heritage structure.

According to the report, the inspection revealed chronic water ingress, cracks in structural components and a complete failure of the terrace waterproofing system.

One of the most significant observations was in the auditorium area, where a sump tank located beneath the wooden flooring was found to be fitted with a pump that regularly flushes out water during high tide, indicating persistent seepage problems.

The report noted that electrical wiring and junction boxes in the sump area showed signs of moisture exposure. It attributed the problem primarily to inadequate waterproofing and high groundwater pressure.

"Electrical and mechanical systems in this zone are at risk; therefore, water stagnation in this area should be strictly prevented through effective drainage and waterproofing measures," the report stated.

The IIT Madras team also flagged concerns over poor indoor air quality in the auditorium, likely caused by prolonged moisture exposure and possible mould growth.

Structural cracks were observed in beams and columns near the stage and catwalk access areas, while the terrace displayed extensive waterproofing failures.

Inspectors found that drain pipes were not directly connected to floor traps, resulting in uncontrolled water flow and stagnation across roof surfaces. The China mosaic flooring on the terrace exhibited widespread map-cracking, increasing the risk of seepage, particularly around service entry points and parapet walls.

"The waterproofing system is no longer functional," the report said, warning that continued seepage could further damage the structural slab and the spaces below.

In the open-air theatre section, engineers observed water stagnation and inadequate drainage around seating areas. Staircases leading to the stage showed signs of deterioration and possible settlement, with reverse slopes detected on most of the steps.

The report recommended a comprehensive intervention involving redesign of the terrace drainage system, correction of drainage deficiencies, restoration of waterproofing systems, elimination of water stagnation, rectification of reverse slopes in staircases and measures to prevent water ingress into service and storage areas.

The findings have renewed concerns over the quality of renovation work carried out at one of Goa's most important cultural institutions and are expected to prompt further action by the state government.
