New Concession Building TA23 Change Order 4, Grayton Beach State Park

Walton County’s Coastal Building Zone Ordinance 2007-53 requires that upon completion of construction of any building located within the Coastal Building Zone, an architect and/or engineer registered in the State of Florida certify that the work was designed and constructed to withstand a wind velocity of 140 mph and Chapter 16 of the Florida Building Code. In order to be able to ‘certify’ that the construction was completed per the design, the following elements will need to be reviewed in the field by an engineer licensed in the State of Florida:

• Review of all foundations reinforcing prior to concrete placement

• Verify batch tickets comply with approved mix design and that water added on-site does not exceed that allowed by the mix design.

• Observe concrete placement for general compliance with the permitted design documents.

• Observe installation of anchors and ties to confirm they are in general conformance with the permitted documents and with ACI 530.

• Observe wood wall installation including nailing and hold-down installation.

• Observe wall sheathing nail patterns.

• Observe wood truss system installation, hold downs, and nailing patterns.

• Observe wood roof sheathing nailing patterns.

• Observe installation of exterior windows, louvers and doors.

• Observe installation of exterior siding and soffits.

It shall be the responsibility of DEP and/or their contractor to notify the design team in advance to schedule these site visits in a timely manner so that the construction schedule is not impacted. A minimum 24-hour notice is required. *Note, it is not anticipated to use all the proposed site visits provided below.
