Use of P.E. Stamp
Use of P.E. Stamp
(OP)
I recently stamped drawings for a residental addition. I specified an engineered lumber beam listing the required Fb and E. The building department came back and said they will not process the permit until I submit a cut sheet for the beam with my P.E. Stamp. This seems like an unnecessary request. Also, it seems to me that this is not a proper use of the stamp. I had nothing to do with the design of the product. Putting my stamp on the cut sheet seem to me like I am certifying the manufacturer's product. Maybe I am just venting. Their other requirement was to have a heating contractor perform heat loss calculations-for a 75 s.f. addition. I would appreciate any input regarding use of the stamp.
Thanks,
Mark

We regularlly just provide the size, Fb and E for engineered wood beams. This allows the contractor to choose which of several different suplliers he wants to use.
We are not asked to stamp steel beams data sheets to state that they are indeed 50 ksi (or whatever was specified) steel, we 'merely' call out the beam size and spec the grade of steel required. This is no different that what you are doing with this wood product.

It sound to me like the Building Department is afraid to take any responsibility. I would ask them if they require sealed cut sheets for all the joist hangers and similair type products.
I agree with you that it is not appropriate for the BD to request you sign a cut sheet on a manufactured product. Your job is to prepare the drawings and specify the requirements that the materials must meet.

You may be required to review and sign off as in a "shop stamp" situation considering you set the loads to tne members, but not stamp.
