Gentlemen,
A representative of Cornerstone Engineering & Surveying, Inc. (CES) evaluated the anchor bolts for the
platform support base plates. Due to the consistency of the rock that the anchor bolts were being placed in,
multiple bolts was causing the rock to split and break apart. Based on the framing design of the platform
extension, minimal lateral load is transferred to the base plates. Two anchor bolts on a base plated will provide
adequate structural support.
No structural items have been reviewed beyond those listed above.
Sincerely,
Cornerstone Engineering & Surveying, Inc.
Michael S. Todd, P.E.
