Febuary 22, 2007 TABLE OF CONTENTS Design Outline and Criteria DC -1 thru DC -2 Structural Details S -1 thru S -2 Structural Calculations C -1 thru C -2 FOR REFERENCE ONLY Mechanical Cut - sheets RF -1 thru RF -7 PROJECT DESCRIPTION: The "Hilltop Business Center Tenant Improvement" project consists of replacing existing roof top mechanical units on a building located in Tigard, Oregon. The new mechanical units are to be placed on adapter curbs directly over the existing curbs. The mechanical unit information is based on cut sheets that were provided to us by Reliable HVAC, INC. The following calculation package verifies if the new mechanical units and curbs require seismic bracing. SCOPE OF WORK: 7340 (BLDG A) Replace 3 five ton rooftop units with curb adapters. Replace 1 seven and one half ton rooftop unit with curb adapter. Note: The existing five ton roof top units weight 607 lbs and the replacement units weight 522 lbs each. The existing seven and one half ton roof top units weight 1,448 lbs and the replacement units weight 820 lbs each.
