Hi, guys....I'm going for a house construction. So, wanted to ask the contruction professionals about some information regarding the foundation type..as per my information a foundation (also called a groundsill) is a structure that transfers loads to the earth.

Foundations are designed to have an adequate load capacity with limited settlement by a geotechnical engineer, and the foundation itself is designed structurally by a structural engineer.

If the foundation is strong then it can withstand severe shocks & other problems...but if the foundation is weak or loose then we may land up into serious trouble.

So, what foundation is best for residential construction...

Let the Structural Engineer decide

idea posted by Khalil Qureshi Civil Engineer-Other, IGBC AP, Free Lancer

The structural engineer is the most competent person who can decide the type of foundation to be used. There are many criteria's that needs to be fulfilled before finalising the type of foundations such as:

1) whether you are building a load-bearing structure or a RCC framed structure.

2) The soil condition and at what depth the strata is available will help you in deciding whether you should go for isolated footing, raft foundation or pile foundation.

3) The planning of the structure also is an important criteria. If you need a basement then you will have to go for a raft foundation, which is generally taken if the soil condition is not good and the strata is at greater depths. Also if two columns are coming quite close then you might have to go for combined/stepped footings.

So my suggestion is that you leave it to the structural engineer who will analyze the site conditions and suggest the right kind of foundation for your house.

Strong & Reliable

idea posted by Pragya Kothari Construction-Heavy, DLF

Hey, Sonali good that u asked this question, because many of us unknowingly make serious mistakes while building the foundation..

Here is what you should do...

If you want a strong residential foundation, make sure you follow the tips below. Use reinforcing steel, don't backfill too soon and leave poured concrete forms in place a couple days after pouring concrete.

Give serious consideration to installing vertical reinforcing rods in your foundations. Most building codes insist that you install horizontal steel bars near the top and bottom of your walls. However, virtually no code (except earthquake areas) requires the placement of vertical steel. In the event that your foundation cracks, I guarantee that it will cost you many times more money to repair the crack than to have installed the steel in the first place.

NEVER backfill a foundation until both the basement slab and the first floor subfloor assembly are in place. These two elements are critical. They are the top and bottom of the "box."

Wait as long as possible to backfill. Concrete or concrete blocks develop strength over time. In fact,under ideal conditions, they often achieve only 75% of their design strength after 28 days!

Negotiate with your builder or foundation contractor to leave forms in place for three to four days if possible. Removing forms the day after the pour subjects the fresh concrete to rapid moisture loss. The concrete needs water for it to gain its maximum strength. During hot or windy weather, consider applying a curing compound to the walls immediately as the forms are removed.

Hope this will solve your problem

Thank you

With incomplete information, it not proper to say something what we know.

The advisers should first know the practcal knowledge on how foundations are decided.

It is better to get in touch with a structural Engineer with all the relavent information and obtain a paid service rather than expecting advises on impartant issues  from people who can debate more with little or no  practicle experience.

Health Oriented and Energy Efficient Foundation

idea posted by Mohammad Bakhsh Consultant(Civil), Rail Vikas Nigam Limited

A good foundation design  must be structurally sound to prevent water and moisture problem and to controll termites and random as well. Apart from,insulating any type of foundation,creates more comfortable condition in below -grade space as well making it more useable for a variety of purposes at a relatively low cost Raising basment temperature by using insulation can also reduce condensation thus minimising problem with mold and mildew.Potential adwantages like,reduced home owners utility bills,moisture,termite controll, serious health affects due to soil gas,most comfotable above grade space, for house with basement,comfortable condition below grade  are selling points.

I hope you may go for a simplex, duplex or bungalow. Just go for a beautiful plan and elevation, which will reflect your imaginations and leave the foundation design to we people.

cnostructing foundation depends in many factore

idea posted by ATANU CHANDA Construction-Construction Management, MARK TECH

Making foundation depends in many factors, specialy it should be desided either it in earth quake zone or non earth quake zone.Depends upon the condition of soil, and height and chrector of the structure. without knowing all this factors giving suggessions is not as per engineering practise.

Many factors are taken into consideration to decide on the foundation to be adopted. The soil condition (evaluated through soil tests) and strata, height, levels and type of the Structure etc. Usually for complex structures a Structural Consultant's advice is sought.

THE FOUNDATION IS DEPEND ON TYPE AND SOIL BEARING CAPACTY DECIDED BY STRUCTURAL DESIGNER

idea posted by mohammed shahebz ur rahman Tech Architect, o'brien akins

The foundation are desiged by structural designer.the structure is most important factor of building.before designing foundation the structure designer has to check the type of soil and have to check soil bearing capacity and have to go for compaction test the sil capacity 95%should come the steel used in building should also be seen according to standard should be checked by you

Following factors are to be taken in consideration :-

Soil conditions or starta.

Type of building .

Weather conditions in the particular area where construction is to be carried out. 

After considering all these factors foundation will be decided.

In many parts of the world, including large urban centers in industrialized countries, neither architects nor engineers are required in residential construction.  I do not know what is required in your part of the world.  You should look into this before you begin. 

However, regardless of what type of professionals you may be required to use in your area, in order to determine what type of foundation to implement you need to know and understand the following conditions specific to your site and area: the type of soil(s) present; the hydrological conditions (both surface and sub-surface); the nature of the topography; the respective building codes (if any); access to the building site itself; and the availability of various construction materials and the skilled labor for building your foundation.  Likewise, you need to have a good idea of the style or type of house you intend to build and the materials to be used in the construction on top of your chosen foundation.  

Keep in mind that some sites can accommodate different types of foundations (e.g., monolithic slab on grade, step-slab on grade, pier and beam, crawl space, basement, etc., etc., etc.) in which case it may boil down to your personal preference, economics and/or relative expertise available to build it.  Regardless, in the final anyalysis it is not so much which type of foundation you build as whether or not it is appropriate to your particular site conditions AND how well it is executed.  The most expertly designed foundation in the world will not serve you well unless it is appropriate to your specific site conditions AND it has been built correctly, conscienciously and using quality construction materials.

Good luck!

Spread footing for Load Bearing Structure...why not?

idea posted by Vivek Singh Project Manager, L&T

Pile, raft, reinforcement, shocks why so big big things yaar. You can also go for simple footings made by bricks to support your walls which will transfer all the load of your house to foundation.

But as every body else said...T&C apply.

foundation any type depends on type of soil and geographic locations. but in my opinion you should leave on experts and follow the design, the most important fact of all consideration is the shape and size of your building. i will say pure geometrical form of an structure will give you the best structural  result in all respect.

thanks

RESIDENTAL BUILDINGS

idea posted by sakthivel site superviser, Sobha Developers

FOR RESIDENTIAL BUILDINGS SIMPLE FOUNDATION WITH COLUMNS(PILLARS), BEAMS, IS QUITE ADEQUATE.

ONLY THING U HAVE TO ENSURE IS THE AVAILABILITY OF HARD SOIL STRATA.

IF HARD STRATA IS AVAILABLE AT REASONABLE DEPTH, THE COLUMN FOOTINGS WILL B NORMAL SIZE, SAY 1 TO 1.5 M SQURE SIZE

IF THE SOIL IS LOOSE, THE SIZE OF THE FOOTING GETS INCREASED BY ABOUT 50%.

if it is a single floor on hard soil, load bearing wall type is ok.

otherwise pillars and beam type should be adopted

Foundation type

idea posted by PRODOSH SEN Heading Design and Quality Assurance in Project Management Vertical, ITC Limited

For an individual owned residential building, normally isolated footing should be sufficient, unless it's a palacial house with basement or it being constructed on a filled up land etc.

But my advice would be to get in touch with a practising structural engineer, show him / her the site, the building plans and follow his / her advice on this matter.

based on load and strata

idea posted by Ravi Project Manager,

Foundations are done to pass on  the structural load into Earth Strata.  we have to decide what is the structure how much load it is going to pass on. Now Strata: what is the Strata what is the  load bearing capacity of the strata. Generally Our structural designers are comfortable with point loaded isolated footing system. Using concrete in foundation is good.

hi .............hire a  rcc  consultant familiar with the area u r constructing your house.

G+1 or G+2 structures are small enough to be taken care by isolated footngs.

soil condition is the most important factor to be considered  and also find out about the seismic zone details of the area.

A local consultant would be the best person to guide and you will also achieve economy with a lot of time saved from your busy schedule.

good luck .........do remember us for house warming.

Structural Consultant Referral

idea posted by S KUMAR Assistant Manager, Pvt. Construction Co.

Dear Sonali,

1. Foundations for specific ground conditions are to be designed by the Structural Engineer based on inputs from the Architect and Geotechnical Consultant
2. Rules of thumb should not be used to finalise the kind or constituents of the foundation

Please refer to the Structural Consultants for a solid solution.
