Permit 22-EP-00027
To Whom it May Concern:
This letter is to certify that I, David A. Bangs (or an employee under my direct supervision) being a duly
licensed engineer in the State of Colorado have reviewed the existing condition of the framing of the
roof for the above referenced single-family residential project. This letter is to address four (4)
modifications to the approved plans.
1. The existing rafters do not meet design load criteria and require (1) 1 ¾”x 7 ¼” LVL to be sistered
to each side of the existing members. This configuration is acceptable to support the design
loading for the roof structure.
2. The existing ridge beam conditions do not meet design load criteria and requires the installation
of a (3)1 ¾”x9 ½” LVL or a 5 1/8”x12” 24F-V4 Glulam beam, bearing on either end and an
intermediate point near the entry of the proposed Bedroom 2.
3. The previously noted header on the upper level, at the entrance of the proposed master
bedroom, will now need to be W8x13 steel beam.
4. The point loads from the header in item #3 will bear on new 10”x26”x26” pad footings in the
crawlspace. Reinforcement will be (3)#4 bars each way.
