CLARK COUNTY DEVELOPMENT SERVICES – EXPANSION & MODERNIZATION
The Clark County Development Services project consists of the modernization of an existing building, approximately 47,000 SF, and the new addition of approximately 75,000 SF.
Martin-Harris Construction performed the project in three phases over three years while maintaining Clark County Building Department occupancy and services to the public. The project provided an expansion and modernization to the existing Inspection, Permit, and Development Services and new space to move additional departments into to the Russell Rd. campus. The simple forms of the 2 story expansion are not intended to compete with the angular and sometimes chaotic forms of the existing building. While the forms do not mimic the existing building, the materials do. Cor-Ten panels are suspended from the building, acting as a thermal screen, keeping the building cool in the hot dry climate of Las Vegas. Cement fiber board is used instead of stucco giving the expansion its own identity. Cement fiber board is more durable than stucco, and has a lower maintenance cost than stucco. Over the years the Cor-Ten will weather matching the existing Cor-Ten.
The main front entrance remained open throughout construction while customer parking was expanded along the east side of the building, with a secondary entrance that connects to the new lobby. The new lobby connects to the existing lobby to create a large, open space to accommodate high traffic customers utilizing a state-of-the-art electronic pneumatic system.
The Owner, Architect, and Martin-Harris worked together to execute value added changes that took the project from the ability to achieve LEED Certification to LEED Silver, without impacting operations of the facility or project schedule. The exterior east and west walls have a trombe wall to block the desert sun from hitting the building directly and help circulate hot air away from the building. The interior of the expansion is mostly open office thus reducing the need for full-height walls and excessive HVAC controls. This strategy is helping the building to meet the maximum energy and atmosphere points allowed under LEED. Lighting is efficient indirect T5-HO fixtures with task lamps at each work station. To reach LEED Silver, the site requirements have been a challenge on this project. All County vehicles, private vehicles and customer vehicles have to be accommodated thus taking up a large majority of the site with asphalt paving. The site will contain all surface run-off being captured in the landscape islands and perimeter landscape zones. All required underground infrastructure has been put in place for a photovoltaic array to be placed above the southern parking lot. This will act as shade structures for parking while supplying the building with power.
