This document provides an overview of the structural and HVAC design for the Rimrock Professional Office Building project. It describes the building as a two-story 18,540 square foot structure with a 4,500 square foot surgical center. The structural design uses a reinforced concrete foundation with a steel superstructure and open-web joists. The HVAC system includes rooftop heat pumps for zoning, with variable air volume and constant air volume terminal units. Ductwork is designed to efficiently distribute heated and cooled air to occupied spaces.

Centrifugal fan which is also called as squirrel cage fan because of its hamster wheel design is widely used to move air/gas continuously in industries and commercial applications. The speed of the air stream entering into the fan, is increased by the impeller thereby it gains kinetic energy and accelerates radially changing the direction by 90°. As these fans are capable of displacing constant volume of air/gas at increased speed, they are widely used in various process applications in industries such as in material handling, boiler applications, transporting gas or materials, ventilation and combustion, air circulation and in other HVAC systems.
