Was hoping for a little imput here.. I have done several building projects including 2 of my own homes from grade work up. Now planning on building a detached garage fr someone I know.. am I way under bid at 30k? Thi project will take place in minnesota..
Details: 30x40 detached garage. Monolithic slab with thickend edges, full fpsf insulation under whole slab and 12"vertical wing insulation burried 12" deep around perimeter, 2 course split face block, 2x6x92-5/8" walls on top of block, 5 1/2 / 12 pitch with spread web trusses 2' oc.. 1/2" osb 30lb felt and ice and water as required and coverd with steel panel roof.. 24" eve and gable overhangs.. cedar siding, soffit, facia installed and stained.. install 8x16 overhead insulated door, entry door, 4 windows, and steps to attic storage with 3/4" osb decking.. also included in price is a 20x30 aprin with 2" 250 stryrene under with perimeter wing insulation...all slab work will be cut and sealed..grade work has been done but may need more fill.... full material cost is running around 22k.. its an easy cut garage for me, but am I too low at this quote? I know that there are plenty of overhead costs to consider like a boom for setting rafters and rental and gas costs... I do have my own skidsteer wit a jib lift for setting walls.. any imput is great.. thanks.
