The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.
Note to Nonmembers: If you join the ICC you can have access to important building safety information!
As an ICC Member, you have access to the Members Area of the Codes & Standards Discussion Forum. Follow the link to discuss the Membership Councils and other benefits of being an ICC Member.

Where in ICC would there be a reference to the required finshed grade for construction. Have had projects that were under HUD guidelines and their requirement was to "see 6" of concrete on the exterior wall" - cannot find any reference similar to that in ICC.
Have a situation where the general contractor intends to have the finished grade up and onto the preast concrete wall panels. The structural engineer indicated something like this but the architectural plans do not.
We are in a squabble.

R404.1.6 Height above finished grade.Concrete and masonry foundation walls shall extend above the finished grade adjacent to the foundation at all points a minimum of 4 inches (102 mm) where masonry veneer is used and a minimum of 6 inches (152 mm) elsewhere.
ICC does not stand for Intentionally Clear and Concise

Thanks for the response and I am aware of this requirement in IRC - BUT where in INTERNATIONAL BUILIDNG CODE will this be. The closest that I can find is IBC 2006 1803.3 Site Grading but does not cite any required distance from finished floor to finished grade.
Need assistance on this.

I think the IRC requirements are to protect wood from insects and decay fungi. The IBC has similar language in the wood section---
2304.11.2.2 Wood supported by exterior foundation walls. Wood framing members, including wood sheathing, that rest on exterior foundation walls and are less than 8 inches (203 mm) from exposed earth shall be of naturally durable or preservative-treated wood.
2304.11.2.6 Wood siding. Clearance between wood siding and earth on the exterior of a building shall not be less than 6 inches (152 mm) or less than 2 inches (51 mm) vertical from concrete steps, porch slabs, patio slabs and similar horizontal surfaces exposed to the weather except where siding, sheathing and wall framing are of naturally durable or preservative-treated wood.
The grade is required to slope away from the building in the IBC, just like in the IRC. Other than that, I don't know of any requirement in the IBC that relates to grade. If one is not using wood framing, it shouldn't matter, provided the foundation is adequately sealed, joints are flashed, etc.

If you say you believe like you should, why do you behave like you shouldn't?

I don't know if you'll find it in the IBC -
one of the few references is for portland cement plaster (stucco) IBC 2006 2512.1.2 - which says
Weep screed shall be placed a minimum of 4 inches (102 mm) above the earth or 2 inches (51 mm) above paved areas and be of a type that will allow trapped water to drain to the exterior of the building.
It could be in a reference code like ACI or PCI - Precast Prestressed Concrete Institute but I only see
MNL 124—89 Design for Fire Resistance of Precast Prestressed Concrete MNL 128—01 Recommended Practice for Glass Fiber Reinforced Concrete Panels
many ACI references
