My evaluation is ba [ ! on information receilled during telephone CDnversalions with you, faxed
Sk:etcheSfconstrUctlonlSi , lis from you of the structure and its support, emailed photographs from you
and from the conlractw. t Carmel Construction and a faxed copy of the Notice of Correctione from the
City of Cam1eVeJay T~ 'ship,

A 20'-8" x 16'-3" ~" : porch has been constructed atop an exterior wood deck. The roof structure
consists of2xB rafle 'iI> ced at 16" o,c. There are 2x4 collar ties on each s~ of rafters appcoximliltely
24' below the ri~ge.,h : roof pitch is 6;12, '!' 2x10 ridge beam is installed. A 2x8 header is installed '
between the upnghts .. p; coXlmately 48' spacIng) to support the rafters.

3,
A 4' long sl!l header ha!;l the approximate Clapaci!y of 450 pounds per linear foot (pit)
whereas tl1e a" 'I design load carried by the header Is 310 pit. Therefore the single 2x8 header
,.
is acceptable ~ i stalled.
The support & i e roof structure consists of a double 2x10 edge beam supported by tl1e
cantilevered ~ ' of double 2x10 deck: support beams. The double 2x10 spannIng between
deck support ; I s is adequate to support the post loads from the r?Of. The cantilevered ends
of the deck s' rt baams are also adequate to support the reactions from the double 2x1 0
beams. The 'j'u' tural ClapE\City ot the6e components is adequate as Installed,
