Arlington County Public Schools: Arlington, VA

The Langston Facility project involved the replacement of an outdated structure with a world-class, energy and environmentally efficient academic facility.

The 60,000-square-foot building was the first LEED Silver rated facility in the commonwealth of Virginia (note: Grimberg exceeded LEED Silver certification project requirements) and is a premier example of the contractor’s commitment to green construction.

Grimberg completed the project on schedule, within budget, and to the owner’s total satisfaction, earning an Association of General Contractors (AGC) award for its overall performance.

Overview

The Langston Facility project consisted of the new construction of an academic building containing classrooms, offices, a gymnasium, kitchen and cafeteria facilities, and supporting areas. Work included the demolition of the existing facility, extensive site work and utilities, and architectural treatments such as brick façade work and roofing. Grimberg also installed interior systems, including major HVAC systems with energy conservation controls and air handling units, as well as installed efficient mechanical, electrical, fire protection, and telecommunications infrastructures.

The project is noted for being the first LEED Silver certified contract in the commonwealth of Virginia. Grimberg’s certified LEED personnel ensured that the job met and exceeded the LEED target goal of 33 points to secure the Silver rating.

The contract achieved points in all areas of the LEED program, including:

• Sustainable sites
• Water efficiency
• Energy and atmosphere
• Indoor environmental quality
• Materials and resources

An additional three points were awarded for innovation credits.

Throughout the project, Grimberg also utilized low toxicity materials to protect the health of building occupants. Moreover, the contractor also developed and executed extensive construction waste management and indoor air quality plans. Grimberg obtained more than 59% of the materials used on the job from post consumer and post industrial recycling. In addition, more than 85% of the project materials were manufactured, extracted, harvested, or recovered within 500 miles of the job site, helping the contractor achieve the LEED program’s local/regional materials credits.
