Precast Construction Technology - Technology
Project Name : Design & Construction of G+3 Storeyed Multi Level Car Parking Block with Precast Technology for SBI DATA Centre at Gachibowli, Hyderabad., Opp: Hyderabad Central University (HCU), Gachibowli, Hyderabad.
1. The campus is functional campus. In and around all the buildings are occupied and in use. In particular the DATA Center for SBI which is working adjoining to Car Parking is to be free from external dust. 2. There was no free space available to stack material and machinery for making green concrete at site. 3. The pollution levels can be controlled / minimized at site. 4. Minimum / optimum usage of water at site. 5. Since the elements are manufacture / cast under control condition, the quantity of concrete is better. 6. Before erection the elements are subjected to physical testing.

Precast Construction Technology
Description
The proposed building is designed and constructed as cast-in-situ up to foundation and precast / pre-stressed in super structure involving columns, beams, hollow core slabs, ramp, staircases, external / internal walls and lift core walls and other precast elements as per design requirements.
Major Gains
1. The pollution levels can be controlled / minimized at site.
2. Minimum / optimum usage of water at site.
3. Since the elements are manufacture / cast under control condition, the quantity of concrete is better.
4. The campus is functional campus. In and around all the buildings are occupied and in use. In particular the DATA Center for SBI which is working adjoining to Car Parking is to be free from external dust.
5. There was no free space available to stack material and machinery for making green concrete at site.
Implementation Strategy

|---|---|---|---|---|---|---|---|
| 1 | The fabricating yard is located at approximately 30 kms from the construction site. Total 10 Nos. precast / pre-stressed elements and 1 No. bed hollow core slab of 150m / 180 sqm. were casted at casting yard per day. The precast / pre-stressed beam curing was done with steam curing for 3 days and curing of other members were done by manual curing method for 10 days at factory. The members / elements transported after getting 75% of 28 days strength i.e., the member could be transported after three days with steam curing and 10 days with normal water curing. The quality of the precast / pre-stressed members as per structural drawing were ensured by deploying one engineer at fabricating yard. Due to restricted space available at site, the various precast elements were transported from fabrication yard in the trailers during the night time and the same were erected in day time on next day. All though, the time assigned for the work was 6 months however, due to revision of the Architectural and Structural design and changes offered by the client, the work could completed in 12 months.
