This 95,000 -square -meter unique facility will support the training, repairs and calibration for hydrological equipment that oversees flow of flow, groundwater, water quality and other water resources.
The space includes a hydraulic laboratory, water quality laboratories, field testing facilities, environmental innovation area, warehouse, training laboratories, network operations center, administrative offices and an auditorium of 150 people. The sustainability functions include more than 500 large photovoltaic panels on the roof and electric vehicles.
The project team passed a series of challenges to maintain the project of $ 89.3 million in the calendar, including the discovery of soils and inadequate material from the demolished structures during the excavation. Due to a historical spill of gas, a gas mitigation system was required throughout the building, including all bases of the groundwater tank. The system has a HDPE/asphalt membrane with ventilation locations to safely disperse gas vapors.
Each section of the system passed smoke containment tests before the subsequent concrete positions, guaranteeing complete coordination and quality control.

Limited information had resulted in the low design of the concrete base for a 250 -feet sloping flow, used to measure the flow of water in open channels. In the same way, the electric service for the inclination, the basin of the basin/wave of 24 feet per 100 feet and the trailer tank required important updates. Narrow commercial collaboration said that these changes were implemented without affecting the critical path of the project.
Detailed installation of the BIM coordination of 15 drains and 10 stainless steel supply lines within the test basin, guaranteeing the alignment with the concrete.
As large hydraulic laboratory equipment had to be installed during construction, the team developed a single scaffolding system to install MEP infrastructure on top in confined spaces more than 40 feet high and obstructed by large laboratory water tanks of 500,000 gallons.
Several operations worked in confined spaces within the water tanks. Specialized training helped to ensure that the operations understood the risks and security protocols associated with the entry of confined space.

To ensure safety around deposits, harsh barricades prevented exposure to water risks. The workers within these barricades carried personal floating devices, a considerable and critical security consideration that led to a safe project.
The team also worked about two major water lines in the project entry area, which could have significant public impacts if damaged. As a result, the equipment used excavation methods of the soft and hydroelectric excavation, ensuring that the water lines remain intact and avoid possible interruptions.
The team also took the preparation for the safety of the tornado. The building has a corridor designated as a tornado refuge for the end user. This hallway was incorporated into the Fort Meteorological Plan of the project team as a tornado refuge for the rest of the project. He settled soon, providing a safe shelter during severe weather events for a significant part of the project.
The project team registered more than 383,000 hours of work with a registered zero incident rate, as well as a zero -time accident rate.
