INFORMATION/BACKGROUND
The Scale House was constructed in 2007 and has operated for 15 years. The Solid Waste Department offers
serval programs and services, many taking place at the Landfill with final transactions at the Scale House.
As the City of Denton and surrounding regions grow, so does the traffic at the Landfill’s Scale House. When
the Scale House was first opened, it was managing transactions of about 600 tons of waste per day.
Currently, it is averaging approximately 1,800 tons a day. The Solid Waste Department seeks to improve
site access roads, scale wait times, traffic flow, and safety concerns under the current system, and expedite
and manage traffic with efficacy and safety.
Amendment 1 of the contract included hiring an Architect for the interior design of the Scale House building
and the preparation of various construction documents but did not include funds for construction
administration.
Amendment 2 includes:
• Changes to the HVAC design requested by Facilities; and
• Provide additional funds for Construction Administration and general Architect/Engineer oversight
throughout the project.
