  • Project Overview

    The Sanitation Districts of Los Angeles County are made up of 24 independent special districts that provide cost-effective wastewater and solid waste management for 5.5 million people in Los Angeles County. Its Joint Administration Office (JAO) facility needed engineering services for airflow modeling of the existing duct system. We were brought on board to design and provide recommendations for increased air capacity.

  • Solution

    We provided drawings and details showing duct repairs by using data collected during the creation of as-builts drawings for JAO. Our team submitted modeling output of a complete duct system at increased flow-rates necessary to support the recommended increased capacity. We formulated recommendations and drawings for duct strengthening improvements and designed detailed duct repair issues and reinforcements determined by modeling or by field survey. This included drawings and details in the LACSD plans and specifications. We also provided air-flow modeling of the duct mains using the Trane “VariTrane” duct design program, and added high pressure ducts feeding approximately 147 double duct variable air volume (VAV) zones connected to the planned rooftop units and branch ducts.
