the Steel Sector, the Company'versified successfully in a wideange of Infrastructure Sectors

through the length and breadthof the country to attain sustain-ability. Today, HSCL is an ISO9001-2008Company and its capa-bilities cover almost every field ofconstruction activities.As a CPSUunder the administra-tive control of Ministry of Steel,

HSCL has always felt the neces-sity and responsibility to increasethe usage of Steel in the country.Apart from executing industrialstructures with extensive use ofsteel sections, the company en-deavors to take up implementa-tion of steel intensive buildingstructures for promoting steelusage.The main considerations behindsteel intensive buildings are:

• Greater stability and seismicresistance.

• Higher space availability.• Lesser construction time.

Some of the major steelintensive projectsundertaken by HSCLare as below1. Ministry of Youth Affairs &

Sports, Govt. of India has anambitious scheme of puttingup small Indoor Sports Hallsat block level across the coun-try under RGKA to promotesporting activities in remoteareas. HSCL has designedsuch Indoor Sports Halls ofan area of around 4000 sq.ft.each using pre-engineeredsteel frames and roof truss.The roof sheeting is by way

of coloured coated steel sheet.Due to the large number ofunits to be made nation-wide,a total steel consumption ofabout 10,000tons is envisagedin the project.

2. HSCL's design of the"Anganwadi Centres" in thestate of Odisha has attractedthe attention of the State Govt.because of its low cost, attrac-tive design and ease of con-struction. The child friendlystructures are designed withpre-fabricated steel and othermaterials to achieve a fast re-sponse. The project has beeninitiated by the Women andChild Development Deptt.,Govt. of Odisha in the Districtof Puri & Khurda. Later on,the model will be extended allover the State.

3. HSCL has signed an Agree-ment with Commissioner,Berhampur Municipal Corp-oration (BeMC), Berha-mpur, Govt. of Odisha forConstruction of 596 newDwelling Units (DU) andup-gradation of 459 DUsin 26 slum cluster Ph-VIfor Berhampur MunicipalCorporation under RajivAwasYojnaat Berhampur which in-volves 1520MT of Steel.

4. HSCL in collaboration withINSDAG in Eastern India hasdesigned and implementedthe uniquely designed build-ing with a frame-work ofstructural steel. Around 562MT of steel has been used inthe modern building of 5 (five)storey which has been success-fully handed over to INSDAGfor making their new officeat Kolkata. This building isshowcased for upcominghousing infrastructures in theseismic zones including theNorth Eastern States.

5. HSCL has successfully com-pleted the work of HandloomMarketing Complex atJanpath, New Delhi which isunique in nature with SteelFramed Structure consuming1410 MT of Structural Steel.

6. HSCL has executed an or-der from the Govt. of WestBengal for making a chain offood godowns designed out ofstructural steel. 15 nos. of suchGodowns have already beenhanded over to the Govt. ofWest Bengal and the same de-sign will be replicated throughrepeat orders.

7. HSCL's design of pre-engi-neered buildings/hutmentswith light steel frame struc-ture and roofing has beensubmitted to the State Govt. ofMeghalaya for their economi-cally weaker sections. Onceimplemented, the project willprovide Affordable Housesto the needy throughout thestate, even in remote locations.

8. HSCL has also designed twoStadiums in the South GaroHills of Meghalaya State us-ing a large quantity of steelfabricated structure for con-struction in the highly seismic

'Housing for All Mission' by 2022.This will also involve consider-able use of steel.

Based on credential and expo-sure in Steel and a wide rangeof Infrastructure Sectors es-pecially in implementation ofResidential and Non-ResidentialBuilding Infrastructures, dur-ing the recent review meetingby Hon'ble Secretary, Ministry ofSteel, Govt. of India, HSCL wasgiven mandate to take up theresponsibility of offering quickand economical solution to the"Housing for all Mission", otherareas beyond Housing like SportsInfrastructure, Infrastructure inSeismic zones and developmentof hilly terrains of North EasternStates etc., keeping in view thepurpose of increasing Steel Usagein the Country.For presenting an ApproachPaper with different options andtechnologies on Steel IntensiveMass Housing, a Workshop wasorganized by HSCLon 26.08.2016in Kolkata with a number of lead-ing exponents in the related fieldof Prefabricated/Precast Housingin the Country.

The offered technological optionshave been taken forward with high

zone. The project is currentlyunder the approval of Govt. ofIndia, Ministry of DONER forfunding.

9. HSCL has started execut-ing the project of ShillongInternational Centre forPerforming Arts & Culture(SICPAC) at Shillong,Meghalaya consisting of 3Auditoriums where a sig-nificant steel structures inthe form of roofing & sup-port frames of steel are beingutilized.

All the projects highlightedabove are promoting the use ofsignificant quantity of steel ascompared to the traditional RCCframe structures consisting ofabout 40% steel components.The up coming NIPER projects at3 places, Gandhinagar, Raibareliand Hajipur and ManipurUniversity will also consume aconsiderable quantity of steel.

Based on the concept of steel in-tensive cluster and low cost hous-ing, HSCLhas sent Expression ofInterest for taking up Housingprojects for slum rehabilitationand affordable housing for ful-filling Government's vision of

level officials in the rank of ChiefSecretary, Govt. of Chhattisgarh,along with Secretary, Ministry ofSteel, during a meeting held on14.09.2016,at Raipur in which aPresentation was also given onPre-fabricated/ Precast technolo-gy.A separate Presentation on thesubject was made before Hon'bleChief Minister of Chhattisgarhon the same day which was wellappreciated by him and the Statecan start venturing into the use ofthese available technologies.The matter of enhancement ofSteel Usage in various Sectorshas also been discussed in de-tail, during the recent meeting ofthe Consultative Committee ofMinistry of Steel on 05.10.2016,at Bhopal, in presence of Hon'bleSteel Minister, Minister of State,Secretary, MoS, Joint Secretary,MoS and other dignitaries.Some salient features of the of-fered technologies are listedbelow:

Simultaneously, HSCL has takeninitiative in exploring options forsubstitution of RCC structures bySteel structures for Road Bridges.Feasibility Reports for rehabili-tation 5 such bridges in the statehave been submitted to Govt. ofChattishgarh. Implementation ofthe proposed schemes is likely tobe taken up in phases. Besidesthis, effort is on to explore thepossibilities of using Steel struc-tures for Rural roads also un-der PMGSY in place of RCCstructures.As a Central PSU under Ministryof Steel, HSCL takes it as one ofits prime responsibilities to bea part of the Ministry's initia-tive for increasing steel usage inthe Country. • •
