Posted by Wayne Quinn Can you tell me if your designs(E 1681 in particular) need any special modification if they are to be placed on a quad bloc foundation. I am thinking of using quad block to a crawl space height.

Posted by Rob Young Could you please describe the foundation you are referring to as I have a couple of ideas of what you might be after, but I want to make sure that we are both on the same page with this. Thanks in advance. Rob Young |
Posted by Wayne Quinn I think one of the trade names is Eco Block..in any case it is a styro wall block that you fill with concrete. The blocks are like giant hollo lego blocks and are held together with plastic clips and allow for re bar reinforcement within. This block is used in place of conventional wood foundation wall forming.

Posted by Rob Young Thanks for getting back to me so quickly on this. That is exactly what I had in mind but I just wanted to be sure you weren't referring to a concrete block pier type system. We can definitely show this type of system for you, if you know which supplier you will be using before hand we will make sure that we show their spec's as they all differ to some degree. This would take us about an 3/4 of an hour to rework the plans to reflect this foundation change. It will take considerably more time if you choose to take this construction up thru the upper floor levels as there are a lot of variables involved. But frankly speaking, if all you choose is to do the crawlspace, then there is no real need for us to change our plans as the supplier will issue their own blueprints for your foundation. Let me know if you have any more questions. Rob Young |

Posted by Rob Young The reason for this comment was that it becomes a concern on primarily our smaller plans where rooms are at their minimum. Most of our larger plans have enough room that you may be able to do this change on site but that is not my recommendation. It is still better to have us make the changes as we are aware of all the structural elements that make up the construction of our plans and therefore can flag any areas of concerns. For example, if you take our A-1225 plan and decide to frame the main floor walls in ICF there are several structural issues to deal with that are more of a concern than just the reduction in room sizes. The added wall thickness affects the staircase in two directions which disrupts the location of a structural column on the main floor which is in place to support the loft and roof over. I could describe this in more detail later if you need a better explanation but for now I just want to point out the outcome. If the contractor failed to realize the entire ripple affect of the changes needed to suit the new stair location, the possible oversights on the roof and floor framing could be a costly mistake. With moving the stairs up to 6" in both ways to suit the desired wall thickness, your main roof girder truss will protrude into the stair opening if not addressed plus the column that supports it will also move and not line up with the support beam below. Even if your contractor does catch this necessary change, if they are not represented in the construction plans then their is a chance your supplier or framer may miss it which again could be costly after the fact. I hope this sheds a little more light as to why we suggest having us rework the plans prior to construction. I understand that it may make the initial plan costs a little more expensive but the additional few hundred dollars spent with us up front may save you thousands in the end avoiding any oversights that can arise by trying to make this type change in the field. Please feel free to contact me directly if you need more information on this. Rob Young |
