Usually involved in the front end design, with a "typical" condition being that of a leadership role through either Schematic Design or Design Development, and then a monitoring role through the CD and CA phases.

The main contractor is the supervisory contractor of all construction work on a project, management of sub-contractors and vendors, etc. May be referred to as "Construction Manager," however, for consistency CTBUH uses the term "Main Contractor" exclusively.
Freeport-McMoRan Center is part of a recent rebirth within downtown Phoenix and incorporates current office and environmental strategies. The building design is a critical response to the existing context of seemingly opaque high-rise office buildings designed to protect occupants from the desert sun’s intense heat gain and glare. The building takes the opposite approach by using transparency and incorporating current glass technology and a high-performance curtain wall system, along with innovative shading to provide sun control. Programmatically the building is unique to the Phoenix market by taking a large office plate typically found in suburban office buildings and placing it on top of a stacked parking structure.
The building is sited north of Phoenix’s existing high-rise core surrounded by the new development of the Arizona State University Downtown Campus and Civic Park. The building is also located across the street from the central bus transit hub and new light rail station making it one of the newest large-scale transit oriented development projects in Phoenix.
The transparency of the building is allowed by appropriate building orientation and varying shading strategies. On the south façade two 61cm (2ft) deep horizontal sun shades per floor provide shading while doubling as a light shelf bringing natural light deep into each floor plate. The east and west façades use a 61cm (2ft) vertical sunshade blocking out low angle sun. Additionally, to supplement the performance of the east and west façade a ceramic frit with a 15% coverage in a gradient pattern increases the shading coefficient of the glass.
Large efficient floor plates with floor-to-ceiling glass characterize the office program. The building corners were expressed by eliminating the corner columns and cantilevering the plate 4.6m (15ft). This gives the corners of the building a visual significance while offering unobstructed views from the interior. The integrated parking structure is naturally ventilated. By using perforated standing seam metal panels the design was able to accommodate views, airflow and natural light.
