CDO was created in the year 1969 with a view to provide higher level of design inputs in multi-storeyed projects which could not be handled by the design units under Chief Engineers. As pressures on availability of land increased, CPWD could utilize the services of CDO for high rise built habitats and complex projects such as jetties and bridges. CDO has provided its services to over 350 projects in CPWD and 35 projects in last four years alone. Important projects designed by CDO are Parliament Library Complex, Parliament Annexe Building, National Gallery of Modern Art, National Museum, Supreme Court Extension, National Stadium, Afghan Parliament in Kabul, Lal Bahadur Shastri National Academy of Administration Mussoorie, Hall of States ITPO etc.
At present, Central Designs Organisation has the responsibility of structural design of complex structures (with structural cost over Rs. 25 Crores) incorporating state of art engineering practices and technology. It is also responsible for contributing to the consultation process of BIS for framing new Codes and handbooks and thus setting standards for the Construction Industry as a whole. CDO also offers its services in preparing several technical documents/reports such as Handbook on Seismic Retrofitting, Design Manuals, Fly ash utilization guidelines, and seismic assessment reports of critical government buildings. CDO also develops computer aided design and planning software such as Integrated Analysis & Design of Buildings (IADB).
Important projects being designed in CDO at present are Extension to Parliament Annexe Building, Indira Paryavaran Bhawan, New Campus for Supreme Court, NWAI Jetty at Kolkata and Guwahati, Underground Parking for Nirman Bhawan, and AG Office Building Lucknow.
CDO is headed by the Chief
Engineer (Designs) who is responsible for the overall administrative and technical
control of the unit. Four Superintending Engineers directly report to the C.E (Designs).
S.Es are the direction officers for control, coordination and execution of all tasks
related to modelling analysis, design, detailing and drafting of structural drawings.
Out of four Superintending Engineers, one is in-charge of Computer Cell CPWD responsible
for e-Governance in the department. Each SE has three Executive Engineer (Designs)
reporting to him, who is responsible for all modelling, design and drafting tasks
and preparing design proposals. Each EE is assisted by a small team of Asst Executive
Engineers/ Asst Engineers, Junior Engineers and Draughtsmen. CDO is manned by civil
engineers having experience in structural design.
All design and drafting
work in CDO is fully computerised. Design and analysis is done by using softwares
such as STAAD, eTABS, STRUDS, SAP, STAAD Foundation etc. Drafting work is done through
AUTOCAD using heavy duty full size HP drafter plotters. Computing is done through
high end Intel Core i7 – 2600 Processors.
A computer cell which was earlier created under aegis of CDO to usher era of e-Governance has now grown into a full fledged E- Governance unit.
