Soil Investigation Taken up in three phases: The initial soil investigation was taken up by Mines, Minerals & Geology Department led by Shri B.N.Sharma, Principal Director followed by Experts from Jadavpur University. As advised, the Mines, Minerals & Geology Department approached the GIS for Geophysical studies and the same carried out by GSI team.
Based on the Geological findings, the structure (foundation) has been designed as per the Codal Practice as enshrined for ‘Seismic Forces’ has been incorporated with the Design Experts from Japan, engaged by the consultant.
Considering the area constraint, this Secretariat Building has been proposed in two Blocks of A & B. Block ‘A’ within the existing site. Block ‘B’ – at Press & Printing Building site. The concept drawing details and the area plan, as approved shall be presented along with drawing design details and model displayed here shortly. As conceived by HCM, the Building Design adopted is a unique reflection of the local identity, featuring local architecture.
The cost of comprehensive project works out to Rs. 277.34 crore, in two phases. Phase I for Rs.224.10 crore and Phase II for Rs.53.24 crore.
Keeping in view the funding under PM’s Relief Package, Part I has further been sub divided into Part A & B.
The Phase I Part A includes both the block A & B along with elevated exit route from the basement floors of Block A, to connect with the Circular road.
The total built up floor area of Block A is 11514 sqm (1,24,000.00 sft) and built up floor area of Block B is 8486 sqm (91,000 sft).
Within the sanctioned cost of Rs.193.00 crore, these two blocks along with Elevated Exit road shall be completed.
The remaining activities viz Tower Block, Sub-Station, Pump House, widening of existing road and New Road Construction to connect the complex with Sonam Tshering Marg (near Assembly House Namnang) can be taken up at a later date as per the availability of fund. In order to complete all the required facilities of the Secretariat Complex, further fund requirement is to the tune of Rs. 84.24 crore.
Block A – It has two basement parking floors, the rest six floors shall be for office use (2B + G + 5). All the important offices like HCM’s Office, Cabinet Ministers’ Offices, Home Department, Planning & Development, DoP, Finance, State Planning Commission, etc. shall be accommodated in this block.
Block B ( at Sikkim Press Building) – It has ( B+ G+ 5) two parking floors and five floors for office space. In the design of the structure the Geo-Technical and Geo- Physical parameters have been taken into account for making an earthquake resilient structure. All technical aspects required for making the structure earthquake resistant even for higher magnitude of earthquake has been taken into account.
As per the recommendations of design experts and findings of GSI, the foundation type proposed is Pile Foundation with raft over it. The average depth of the pile foundation is 15m (50ft) from the basement floor ( - 2 floor) which is about 8m below the ground level of old Secretariat building.
The building confirms to the requirement of BIS/NBC (National Building Code) norms.
It conforms to Green Building concept, Local architectural touch is given to make the building unique and beautiful.
The Secretariat building shall have state of art facilities. All the Government Departments’ Heads shall be housed within the complex.
The earthwork excavation for creation of two basement parking floors (7.5 m-9mtr depth) was completed in October 2012. Now, excavation for Pile foundation is in progress.
For establishment of NIC Offfice Building and State Bank of Sikkim works are being taken up and shall be shifted immediately after its completion.
The work is awarded to M/S Archtech Consultants Pvt. Ltd. (ACPL) Kolkota on Turnkey Basis for Consultancy, Design, Drawing and Execution. The building Block A Phase I ( Part A) in all probability has been targeted to be completed in all respects by October end 2014, and ready for accommodation within the month of November 2014.
Block ‘B’ would take time to complete since the site is yet to be made available for various unavoidable reasons especially the complete shifting of Press & Printing establishment to the Sikkim Jewels Building, Tadong.
