This isn’t the subject we originally planned to write about. Things changed for you and for us very quickly in the last few weeks. Changes that still seem unimaginable.
Most of our team across the country is working remotely. Most of your team is likely doing the same. We’ve created space to work beside our kids on coffee tables, kitchen tables, and for the luckiest, in home offices. We are using technology to meet, design, talk, and collaborate just as we would in an office – keeping our clients and colleagues close, on computer screens rather than in conference rooms. Some of our staff continue to work in offices and on job sites supporting the critical work your teams are directing and implementing.
Our people are considered essential - professionals supporting vital infrastructure and services. We are continuing to support work on roads, bridges and utilities, and we are being called upon to assist with emergency projects that are directly related to the current crisis. We are mobilizing quickly and answering the call to support our communities, states and country, just as you are doing.
From expanding broadband to support home schooling and remote workers to assessing and retrofitting facilities urgently needed to add hospital beds, we are out there with you. As things return to normal, we’re ready to support efforts to ensure clean indoor air and re-organize spaces to accommodate safe distancing as well as other environmental challenges facing your business, agency or community. CHA will be there to guide, support and assist when and where you need us.
Historic Whittier Field
Bowdoin College’s Whittier Field in Brunswick, Maine, is one of the most storied collegiate football fields in America. It opened in 1896 and after numerous additions and modifications, needed restoration that preserved its much-loved history, but added modern amenities to meet the athletic and recreational needs of Bowdoin College.
Renovated in two phases, the initial phase replaced the grass field with artificial turf and added lights, seating, and a new two-level press box, along with expanding the six-lane track to the eight lanes necessary to host NCAA championship track meets. The exterior of Hubbard Grandstand, which was added to the National Register of Historic Places in 2017, was also rehabilitated. Bleachers that had been built around it were removed and relocated to showcase its historical architecture.
The second phase relocated a public roadway, constructed a one-story team/spectator support facility, and completed the east end of the additional spectator seating constructed in Phase 1. The support facility houses locker, training, and equipment rooms and modern spectator restrooms.
Lake Champlain PV-20 Submarine Cable Replacement
The Lake Champlain PV-20 Submarine Cable Replacement project removed and replaced seven 50-year-old oil-filled cables beneath Lake Champlain, which connected transmission systems in New York and Vermont. The condition of the cables threatened the system’s reliability and risked an oil leak in a sensitive aquatic environment.
While minimizing environmental disturbance, four 230 kV electric transmission cables (operated at 115 kV) were installed using four different methods. Cables on land were installed through direct burial. Horizontal directional drilling, a trenchless drilling technique, transitioned cables from land to lake. At a water depth of 30 feet, a jet plow towed from an installation barge installed cables four feet into the lake bottom and cable was directly laid beyond a water depth of 100 feet. In Vermont, divers buried cables four feet into the lake bottom by hand water jetting.
Cass Adams CSO
The Integrated Overflow Control Plan (IOCP), developed by the City of Evansville, Indiana, addresses water quality in the Ohio River. One major control measure is restoring Bee Slough, a large open concrete-lined swale conveying most of Evansville’s combined sewer overflows (CSO). The Cass Adams Relief Sewer was the first project within Bee Slough intended to provide 100% CSO control.
New drains direct CSO flow to the East Wastewater Treatment Plant through 5,000 feet of 60-inch relief sewer and a dewatering pump station. The sewer is maintained by a large retaining wall stained bronze and adorned with architectural revels and lighting. In remedying CSOs while beautifying the area, this project signifies the City’s commitment to using the IOCP for more than water quality mitigation.
The View From Above
Drones have been in the air for more than fifteen years, but the last three years have seen an explosion of their use for commercial purposes. The construction and engineering industry is now the fastest growing industry to adopt drone technology for efficient, accurate and timely capture of data. In addition to collaborating with clients in real time and documenting projects from a unique visual vantage point, drones and the data they are able to effectively acquire can integrate with all aspects of planning, design and construction.
The potential uses of drones continue to expand as the technology improves and becomes more sophisticated. Drones can capture construction progress photos and videos, extract surface areas and volumes for construction reporting, inspect structures or areas not accessible in traditional ways, and capture 3D clouds and images for existing conditions models. Drones may also be utilized for thermal imaging, 3D mapping, obstruction observations, pre-site surveys, hydraulic modeling, surface and structure inspection, and asset management.
Drone technology is now being utilized across the engineering industry from aviation to transportation projects. For example, an engineering team may secure drone footage to provide a 3D model of a neighborhood and the tree canopy adjacent to an airport to determine which trees extend vertically in to the runway approach. For a transportation project, drone video might be used to create a 3D model of the streetscape of a proposed corridor to share with stakeholders in the community. For projects with significant environmental impact such as landfill closures, drones may be used to provide weekly construction observation photos to ensure proper placement of closure materials and to aid in communication with field staff. Of course all of these uses depend on a process to scale a drone program to the organization’s needs, manage the data and ensure collaboration and integration with other design platforms.
Clearly, the industry is only scratching the surface of drone capability and the many ways to utilize this technology. CHA currently has a fleet of three drones and six FAA Certified 107 Pilots with plans to add 2 more drones and four additional pilots in 2020 to facilitate improved vertical accuracy, extended flights and a more versatile platform for optics and sensor expansion.
