CASE STUDY FOR TOC Project Detail- 55,000 TPA Fe-Cr Plant Start Date- Apr’13 Finish Date- Mar’15 Location- Gopalpur, Odisha Introduction Ferro-chrome plant has an installed capacity of 55,000 tonne per annum (TPA). The plant was commissioned in Mar’15 and inaugurated in November 30, 2016, It is a unique environment-friendly plant with state-of-the-art pollution control equipment and technology such as the ETP (Effluent Treatment Plant) and STP (Sewage Treatment Plant). It has 100% water harvesting facility that caters to most of the water needs of the plant. It has an indigenously built semi-closed hybrid furnace, which is first of its kind in India and components procured from all over the world to maintain high standards of quality and safety. Also, it is the first plant in India to use briquetting method of Chrome ore fines agglomeration.

Use of Metal Deck Sheet in place of staging & shuttering to support concrete slab in furnace building Completing a project on time and on budget with the best quality is most important thing. Delivering a project within the time frame will helps us to build the trust. Trust, will open a new door for business growth. Business growth and revenue is the main focus for any organization or any business owner. As a business owner, when we decide to take on a new business project, our instincts may tell us that managing it will be fairly straightforward. However, the ability to successfully manage projects is a valuable skill that takes a great deal of knowledge and experience. In past, We came across a project where time frame and local labour was constraint for us, being a high value project public had an eye on the day to day development of the project. In furnace building, the area of one floor was 1600sqm consisting of 5 floor with area of 8000sqm and approximate time frame to complete the work was 6-7month with approximate engagement of 120 manpower/day for the conventional method. Since, In conventional formwork for concrete slabs, we use separate formwork (staging & shuttering material) to support the reinforcement & concrete during casting. This is a time consuming job as fixing of formwork has to be done manually & takes more time (6-7month) and manpower (120mm/day). Metal deck sheet for concrete slab To reduce the construction time & manpower, use of metal deck sheet is recommended due to following reasons:1) 2) 3) 4)

These sheets are used as a working platform to support the reinforcement & concrete. These can be easily installed and fitted. No separate formwork required for slab casting. Reduces construction time, which is approx. 70 days in our case. 5) Safer to work as manual fixing of staging & shuttering may lead to accident. Recommendation We used the metal deck sheet and saved of approx. 70 days in construction time in furnace building with less nos of manpower engagement. By commissioning the plant 70 days in advance we had achieved the Fe-Cr production of approx. following value:-

a) b) c) d)

Considering initial production (MT/day) Rate of Fe-Cr (Rs/MT) Cost of one day production (axb) No. of days saved by casting furnace floors 70 days advance using Metal deck sheet (days) e) Expected Benefits to be earned by advancing commissioning by 70 days (cxd)

: 100 : 1 lakh : 100 lakhs : 70 :7000 lakhs

Considerations for our recommendation TSL got benefitted by advancing completion of Furnace platforms provided other enablers/drivers of the project like 220 KV power at MRSS, soft water plant, Briquetting plant, MRSS, electrical buildings & other structures will get ready as per schedule before cold trial. Hence, advancing the furnace floors by using metal deck sheet was one of the factors to save the project time. The activities which were falling on critical for when it comes to use of deck sheet was a) Redesigning of furnace building floors considering metal deck sheet that took 20 days after clearance from TSL. b) Procurement of Structural Steel material & metal. c) Contractor is engaging optimum skilled civil manpower for the platform work.
