A foundation plan drawing for a new house

by admin on October 16, 2012

The foundation plan drawing is one the most basic of the construction drawings.

It should show the foundations design and how it’s intended to be constructed.

The sizes for strip foundations are around 26″ x 10″ or (650mm x 250mm)

The example below shows the size and layout.

The plan should be boldly outlined with a black pen and then colored to represent the concrete.

The proposed house walls are shown in a dotted line on the plan and are noted “Line of External Walls” you do not have to add openings or any details just a clear dashes line above the foundation drawing which can be referenced clearly for when it comes to setting out the guide line profile.

What is Foundation Plan?

A foundation plan is a drawing which shows a plan for the appearance of a basement or foundation.

This foundation plan may include some key structural information about steel beam and poles, and where materials will be used in this plan.

A foundation can anchor a home to the earth and it also works to support the weight of the home.

There are actually many varieties of foundations to choose from, and this will depend on the geography of the home and the soil on the construction site.

While it may not seem that way, building a solid foundation is an art form and there have been many books written about the importance of doing it right.

Let’s take a look at some common types of foundations, and each ones pros and cons.

One popular choice for foundations is a full-basement foundation. This is a great choice if the home is being built in an area where the ground will freeze during the winter.

You’ll find with a full basement that there is either poured concrete used, or concrete block wells that are around 8 ft. wide and 9ft. high.

What is the best thing about having a full basement? It provides your home with extra room that can be used for storage of items, or for utilities like the hot water heater.

If you work with this space it can even be turned into living quarters for a family member or guest.

What is one of the downsides for a full basement foundation? Well they do frequently add to the cost of your home building, due to the level of excavation, forming and level of materials required.

There is also the tendency for moisture issues to occur in a full basement foundation, so be prepared for this.

Another frequent choice for foundations in homes is a crawl space foundation.

If you are building the foundation in an area where the ground does freeze in the winter, but you don’t want to put in a full basement, then crawl space foundations are another option you have available to you.

A crawl space foundation requires the use of concrete and block walls and these form frost walls or stem walls for the foundation.

In terms of preparation for this, getting a crawl space foundation is easier and takes less labor to complete.

There is less concrete that needs to be poured and laid out, and this adds up to major savings when compared to a full basement.

The area that is often between the foundation walls is in most cases bare soil, which needs to be sealed in some way so that moist conditions cannot cause mold in the home and cause rotting.

Another disadvantage that you’ll face with a crawl space foundation is the inconvenience factor of needing to do any wiring or plumbing work in a highly claustrophobic space, which can be very detrimental for repair work later on.

Slab foundations are a very common foundation choice for those who live in milder climates and places where the frost line is shallow.

Slab foundations are easy to install and can be done quickly, receiving their support from the short stem walls that are formed and poured separately.

In warmer areas like the Southwest, the excavation and installation process are much easier.

When the surface soil has been cleared away there are trenches that have been excavated for use as footings.

From there the slab and the stem wall are poured as a monolith-type unit with built up edges.

This supports the weight of the house and distributes it evenly.

The biggest advantage is the house being connected to the slab, which lowers the materials and labor costs that other foundations bring.

One major issue with slab foundations is that once the concrete and slab are formed, it is hard to change any issues.
