Calicut as Our Base
Calicut (officially Kozhikode) is one of Kerala's major cities and a significant commercial and educational hub on the Malabar Coast. Our office at Landmark Meritus Commercial Building, Thiruvannur, Calicut places us at the centre of one of South India's most active construction markets. Kerala's Gulf diaspora — one of India's largest — has historically driven residential construction investment in the state, while infrastructure expansion and commercial development continue to grow the non-residential construction sector.
Kerala's Construction Landscape
Kerala presents several structural engineering challenges unique to the region: laterite soil conditions prevalent in the midlands requiring careful foundation assessment, coastal zone construction with marine exposure durability requirements, hilly terrain in the Eastern districts requiring slope stability analysis for foundations and retaining structures, and high seismicity risk in certain parts of the state that demands appropriate lateral force design. Calicut itself sits in a coastal zone with direct exposure to the Arabian Sea monsoon — wind loading from monsoon conditions must be properly accounted for in structural design, using IS 875 Part 3 wind load provisions calibrated to Kerala's wind zones.
Applicable Codes for Kerala
Structural design in Kerala follows the National Building Code of India 2016 (NBC 2016) and Bureau of Indian Standards codes. For structural steel, IS 800:2007 (General Construction in Steel) is the primary standard. For reinforced concrete, IS 456:2000 applies. Seismic design follows IS 1893:2016 — Kerala is classified in Seismic Zone III, requiring consideration of seismic lateral forces, ductile detailing of reinforced concrete frames per IS 13920, and foundation depth requirements for adequate anchorage against seismic uplift. Foundation design follows IS 2911 for pile foundations and IS 1904 for shallow foundations, with soil investigation per IS 1892.
International Experience from a Kerala Base
What distinguishes Sixteens Consultancy Services from other Kerala-based structural consultancies is our international project record — 14 countries across 4 continents, with demonstrated proficiency in ASCE-7, AISC-360, ACI-318, IBC, SBC, NBC 2020, JIS, and Eurocode. This international fluency directly benefits Kerala clients: we understand structural best practices from the most demanding international markets and apply that knowledge to Kerala projects. A steel structure designed with the rigour we apply to a Saudi tower is a better-engineered structure than one designed to the minimum local requirement.
Based in Calicut, experienced internationally. Sixteens is the Kerala structural consultancy that has designed steel towers in Dammam, observation towers in Japan, and waterslide supports in Florida — and applies that depth of experience to every local project.
