Introduction:-

B.G.Shirke Construction Technology Private limited (BGSCTPL), formerly known as B.G.Shirke

& Company, was established in 1944 by its founder chairman, Mr. B.G.Shirke. It is a multi-

disciplinary civil, mechanical and electrical engineering consortium with seven international

technology tie-up and over 12000 workforces.

It is vibrant, dynamic and integral part of modern India, significantly contributing industrial,

economic, social progress.B.G.Shirke also pioneered and patented the “3S System” in India. 3S

System means – Strength, Safety, and Speed.

Strength: - Trained & Skilled employees, fully automated plant is their strength.

Safety: - For all the students they gave safety helmets.

Speed: - for each & every activity there are machines, so whole work get boost up. Hence

they achieve speed in production, transportation and construction.

The company has so far executed more than 2, 00,000 dwelling units using 3S System both in

India & Overseas.

We were reached on site at 11’O clock. The Site details explained by Er. Shrikhande sir – GM

Project and further we had proceeded for visit with Project Manager Vaidya Sir other team

members.

Site Observations:-

The visited site has proposed G+11 floors plan. The construction is in progress, the footing

construction is almost done up to plinth level. The building consists of around 1,00,000+ columns,

2,00,000+ beams, 54,000+ plinth beams, 18,000+ slabs. This entire units are precast units; all are

casted in factory as per specification under control system.

They have to construct around 180+ mass housing scheme, some of them are G+11 and some are

G+14. All building are resting on hard black basalt, about 90% building foundation are rest on

directly on basalt and only 10% on pile foundation.

Factory shed

The whole precast plant is fully automated plant all work is done by heavy machineries minimum

amount of labour are there. For each and every activity machines are used. i.e. For cutting of bars,

for stirrups, for welding etc. For lifting of reinforcement and precast member there are heavy

girders.

The factory consists of batching plant, storage plant. They cast all the units separately i.e. there

are separate place for slab, beams, columns etc. The whole unit is made sequentially by fully

automated machines and it takes around 40min to 45 min to complete one cycle.

We had seen the casting process during the slab casting is in progress, the placing of

reinforcement, its cover, its spacing, amount of concrete poured, its compaction etc. M30 grade of

concrete is used for the entire unit with vary slumps as follow.

The visit was concluded with vote of thanks by Prof. A.G.Tanawade. The site visit was very

informative and the students got the feel and knowledge about the different processes required to

Manufacture precast elements for construction purposes.
