Re: footingsFrom: info@builderswebsource.com CommentsI have some general cautions with the recommendation made by the PCA regarding your foundation. First, for record, the PCA is an excellent source of information on concrete construction techniques and they do offer a lot of expertise. The person giving you the advice, according to your message, was a civil engineer -- which is good. However, as with any project, the type, size and construction technique for your slab foundation must be based on specific engineering calculations, which has to account the soil conditions in your area. If your home is to be built on expansive clay soil, you will have one type of foundation and footing combination. If you live on landfill, you'll have a different type of foundation. If you're on rock or sandy soil, you may have yet a different type. Without knowing the geo-technical conditions and the design loads of exterior and interior partitions, it is not possible to design a proper foundation unless the engineer who made the recommendations already had this information. Furthermore, the amount, spacing, size and configuration of rebar for footings and the slab also needs to be part of the foundation design. If you live in a seismic zone, there are other considerations that come into play, such as hold-downs which may be required on both exterior and interior shear walls. These must go deep into the footing, which has implications for how your slab is poured and whether it floats or is a monolithic structural slab. If you can provide some additional information about your specific conditions, we may be able to point you in the right direction. Ultimately, a licensed structural engineer who knows the exact conditions of your soil conditions can give you the best advice before settling on a particular design strategy. Builders Websource
