What is the difference between a Commercial Pump Station and a Commercial Lift Station? If you have a permit for a pump station can you turn it into a lift station?

Chirag says:

I’m currently in 3rd year Civil Engineering and have decided to go for Structural Engineering.
Can you suggest me what college is good for Structural Engineer and here (anywhere around the world, Most preferable in India).

i want to know about the mix design for hydralic paver block using 6mm aggreate

Konsong says:

A simple curve have tangents AB and BC intersecting at a common point B. AB has an azimuth of 180 degree and BC has an azimuth of 230 degree. the stationing of the point of curvature at A is 10 + 140.26. the degree of the curve is 4 degree. Can you show me the figure of this problem?

what is meant by granular bedding material for laying pipes? other than sand which material is used as granular bedding.

Adarsh sharma says:

Which is better for house making blocks or bricks


I feel mild tremors in my flat (2nd floor) due to closing of the main door at immediate upper floor (reason-Children do door closing with force) . The building is new-two years’ old. I otherwise find the material used in the building is good.

It is 4.5 floors’ building with stilt parking.

Can tremors be dangerous?

R K. Banik says:

I have constructed rectangular room 12f×24f with 6 pillars 12f apart from each other. Pillars are of 8inch×8inch with 4 nos 12mm rods and horizontal beams 8inch×10inch with 2 nos 16 mm(lower) and 2 nos12 mm (upper) rods. No slab yet cast. But two upper beams showed crack in the middle.Is it possible to repair the crack and how?

Awais says:

1: What should be the column and beam size for G+2 25’X50′ house?
2: If columns & beams sizes are same on 2nd floor as on G.F then how can we hide the projection of columns & beams on 2nd floor because we try to raise 4″ walls, especially partition walls?
3: Can we use L shapes or T shaped columns in this house? and use 4″ thick at same brick size with is 4″ L shape column at corner to save space and avoid projection?
4: Can we use 4″x15″ columns on 2nd floor or what is the minimum size should be on 2nd floor?

Deric A Schmidt says:

I want to put a 40′ shipping container in an area that is existing dirt. I dug a hole to find sand stone 2 ft down. I want to know how far down I should remove the dirt and replace with gravel to support my 8’x40′ container weighing 15000#.

Richard says:

How to choose whether the beam is simply supported or fixed??

Richard says:

How to design secondary beam ( calculations)?

Devyani says:

I am designing a Girder and using Steel I beam columns. Should the flange side of the I beam column connected to the load bearing Girder beams? Or the Web side of the column?

Praful Parikh says:

I am helping a farmer making bore well for him , for collection of water I am building 20’x20’x10 ‘deep RCC tank on 6,,,6″x6″ RCC ,5’above the ground pillars, and base and 4 walls are 4″ thick RCC , is this structure is safe enough > or should I increase the thickness of walls and base ?
if possible please reply to my e mail ID or time permits please call me

Ayush says:

Sir ,
Can you give me study material for silber kuhi system,design of prefabricated elements?

Balaji D says:

Hi pls clarify my doubt.
Construction workers are using waste oil mixing with cement mortar while laying weathering tiles, is this a right way? If so what is the use of the same ?

charitha krishnammagari says:

i have a question about who designs the parameters like footing column
example :- 200*200 size of a column
who says this and how

Abhishek dubey says:

Can I build the 2 floor over existing structure with 200×200 mm size 8 columns and plot size is 13×30 sqft.

Divy Pratap Singh Sengar says:

Sir, I would like to ask that if both tension and compression force acts on beam and let us consider simply supported beam then below the neutral axis why cannot we use lower grade of concrete because at the bottom to withstand tension we are already providing steel as there is negligible compressive force at the bottom. It will make the structure more economical.
What u suggest??

AnkalaS says:

What is the best way of modeling, analysing and designing a double-decker flyover?

Yash Chamadia says:

Load Carrying Capacity of Column 9’x12′ with 6 steel bars of 12mm according to formula Pu =0.4 fck Ac + 0.67 fy Asc comes out to be 720KN, Taking safety factor of 1.5 its 480KN. Since 1KN is equal to 100 KG appx., therefore load carrying capacity of column coumes out to be 48,000kg. Is this calculation correct or am I missing something.
