Why a tensile structure in Port Blair
Port Blair is the capital of the Andaman & Nicobar Islands and the base for almost all activity there — tourism (Cellular Jail, Corbyn's Cove, the jetties for Havelock and Neil), government and administration, the port, and institutional buildings. The tensile-structure demand is waterfront, tourism and public-realm: shaded viewpoints, jetty and queue cover, plaza and event pavilions.
Ekra Decor's documented Port Blair project is a set of conical tensile canopies — about 121 m² — over a paved waterfront area, completed in 15 days.
Port Blair is the most logistically demanding site Ekra Decor serves: everything ships to the islands, so members are cut, drilled and match-marked at the mainland workshop and the on-site work is bolt-together assembly and tensioning by the in-house team. For the full technical background, see the tensile structure guide.
How the local climate shapes the design
An island in the Bay of Bengal is the most demanding environment there is — salt, rain, cyclone wind and Zone V seismic all apply. This is general climate information for the area; the wind, rain and snow values used in a structural design come from the site survey and the applicable codes, not from a page like this.
Intense, unrelenting salt exposure
An island site is the most aggressive corrosion environment there is. Every steel element is hot-dip galvanised and coated, and all exposed cables, plates and fittings are stainless steel.
Very high maritime rainfall
The Andamans receive a long, heavy monsoon from both the south-west and north-east — well over 3,000 mm a year. Drainage is sized generously with a designed overflow route.
Cyclone & storm-wind exposure
The islands lie in the Bay of Bengal cyclone belt. Wind uplift is taken to the severe coastal design figure under IS 875 Part 3, and the anchorage detailed accordingly.
Highest seismic category — Zone V
The Andaman & Nicobar Islands sit in Zone V. The frame and its foundations are detailed for the most severe seismic category.
Warm, humid maritime climate
Warm and humid year round with little seasonal swing; ventilation and a light membrane matter more than thermal movement.
Logistics are part of the design
Everything ships to the islands. Members are cut, drilled and match-marked at the mainland workshop so the on-site work is bolt-together assembly and tensioning.
Tensile structures that make sense in Port Blair
Waterfront, tourism and public-realm, matching the island's activity.
Waterfront & jetty canopies
Shaded viewpoints, queue and waiting cover at the jetties, and promenade pavilions — as built for the Port Blair waterfront. Custom fabric structures →
Conical & feature pavilions
Single- and multi-peak cones over plazas, event spaces and tourism sites. Conical tensile structures →
Government & institutional canopies
Entrance, assembly-area and walkway cover for administrative and institutional buildings. Walkway tensile structures →
Resort & hospitality structures
Beach and poolside shades and dining-area cover engineered for the island climate. Gazebo tensile structures →
Market & public-space cover
Membrane roofs over markets, bus stands and public gathering areas. Tensile roofing structures →
Car & two-wheeler parking
Shade over visitor parking at tourism sites, with a full marine steel specification. Car parking tensile shades →
Membrane choice for the local climate
On an island, corrosion is the entire conversation — every fitting is stainless, every steel element galvanised and coated.
PVDF-lacquered PVC
The PVDF top-coat resists salt-laden humidity and UV and stays cleaner in coastal air. PVDF fabric →
PTFE-coated glass
Chemically inert and near self-cleaning — the best-in-class choice for a permanent coastal structure or a fire class. PTFE fabric →
PVC-coated polyester
Only for a short-life or sheltered structure; a plain PVC lacquer chalks faster in salt air. PVC fabric →
On the coast the steel specification matters as much as the fabric: hot-dip galvanising plus paint or duplex coating, and stainless cables and fittings where exposed. Full comparison on the membrane materials page. On an island this specification is mandatory, not optional.
Engineering for local conditions
Points that come up on a Port Blair project. No structural values are quoted here.
- Site survey & soil investigation — island soil varies; foundations are sized from the site's own soil investigation to IS 456, and detailed for Zone V seismic action.
- Wind — wind uplift is taken to the severe coastal, cyclone design figure under IS 875 Part 3, and the anchorage detailed for it.
- Drainage — steep falls, oversized gutters and a designed overflow route for one of the highest rainfall totals in the country — well over 3,000 mm a year.
- Full island corrosion package — hot-dip galvanising plus paint or duplex coating on the steel, and stainless steel for every exposed cable, plate, pin and fitting. Nothing bare is left in the salt air.
- Seismic Zone V detailing — the Andaman & Nicobar Islands sit in the most severe seismic category; the frame and foundations are detailed for it.
- Match-marked, bolt-together fabrication — everything is made and trial-fitted on the mainland and shipped, so the island work is quick assembly with minimal site tools.
- Corrosion protection — the steel is hot-dip galvanised; the coating class is set by the local air.
- Thermal movement — the seasonal temperature swing is designed into the connections so the membrane never slackens.
- Off-site fabrication — steel and membrane are cut and made at the workshop and shipped, so the on-site work is assembly and tensioning.

How Ekra Decor covers Port Blair
For Port Blair, Ekra Decor's service area is the city and the accessible parts of the Andaman & Nicobar Islands. Everything is fabricated and trial-fitted at the Delhi NCR workshop and shipped; the same in-house team travels to site for assembly and tensioning.
No local office, factory, warehouse or team. Ekra Decor works across India from a single Delhi NCR design, fabrication and installation base — the same in-house team surveys, engineers, fabricates and installs every project, Port Blair included.
One in-house team, concept to maintenance
Practising since 1998

Genuine membranes
Traceable architectural fabric from established manufacturers — Serge Ferrari, Mehler, Heytex — with test certificates supplied.
What drives the cost of a tensile structure in Port Blair
The same factors apply everywhere; the mix changes with the project and the site.
There is no meaningful fixed rate per square foot — two structures of the same area can differ by a wide margin. Distance and site access affect the logistics line, but there is no flat “Port Blair premium”. Send your requirement for a design direction and an itemised quote; the tensile structure cost guide sets out every factor.
Tensile structures in Port Blair FAQ
Questions specific to tensile structure projects in Port Blair and the Andaman Islands.
Yes. Ekra Decor built a set of conical tensile canopies over a paved waterfront area at Port Blair, completed in 15 days on site. Everything was fabricated and trial-fitted at the Delhi NCR workshop and shipped to the islands; the in-house team travelled to site for assembly.
Yes — the waterfront canopies shown above. It is the company's documented Andaman project; its Diu pavilions are comparable marine-specification coastal work.
No — there is no local office or team. Everything is delivered from the Delhi NCR base; the islands are the company's most logistically demanding site.
With a full marine package, which on an island is mandatory: the steel is hot-dip galvanised and painted or duplex-coated, and every exposed cable, plate, pin and fitting is stainless steel. Nothing bare is left in the salt air.
Yes — the wind uplift is taken to the severe coastal, cyclone design figure under IS 875 Part 3, and the anchorage and foundations detailed for it, alongside Seismic Zone V action.
Every member is cut, drilled and match-marked at the mainland workshop and trial-fitted before shipping, so the on-site work is bolt-together assembly and tensioning with minimal site tools. The Port Blair canopies went up in 15 days.
There is no fixed rate per square foot. Cost depends on the area, span, form and site conditions; the full marine specification and the shipping logistics both add to the total for an island project. Send your requirement for an itemised quote.
