The National Tax Headquarters in New Delhi, India. © CSA Partners Ltd.
The National Tax Headquarters building will consolidate the Government of India’s Central Board of Direct Taxes (CBDT) and the Central Board of Excise and Customs (CBEC) departments into one energy-efficient facility. The complex will house offices for the Finance Minister, the Minister of State and Department of Revenue and will provide spaces for various other offices and support facilities.
The building was designed to be accessible to the public, and to blend with its context. It features glass-enclosed indoor plazas that allow natural light to the interior spaces while providing a visual connection to the landscape. Symbolic of the density of the surrounding trees, the building is organized in an inverted hierarchy with the more populated offices located towards the top of the structure while smaller office pods and public plazas are below.
Thornton Tomasetti is providing structural design services for the nine-story, 450,000-square-foot steel superstructure. Working with the architects, the engineers helped design a system that allows the entire building to rest on nine, reinforced concrete service cores from which a set of trusses that span the cores are hung top-down to support the lower floors. The basement will be built using conventional reinforced cement concrete, while the entire superstructure will be predominantly made of steel.
