Engineers design solutions to tackle low-frequency noise

Phys.org | May 21, 2019

Low frequency noise 500 Hertz and lower, which could stem from various sources such as construction machineries and aircrafts, is a form of environmental noise problem in urban environments. Such noise transmits over long distances and cause disturbance to wide area. It is also known to trigger a number of negative physiological reactions such as changes to blood pressure, vertigo and breathing difficulties even when the noise is not audible.
Most commercially available noise canceling devices and structures today, however, are only effective in reducing high frequency noise, while low frequency noise continues to penetrate through these structures. To more effectively mitigate low frequency noise, a team of engineers from the National University of Singapore (NUS) has therefore designed a set of novel noise attenuating blocks that targets low frequency noise.

Engineering is saving lives and protecting cities from the impacts of earthquakes. Earthquakes can be incredibly devastating, and throughout history, there have been countless examples of entire cities being brought low, with damage even causing fires and flooding afterwards. Less than a century ago, a strong earthquake could sometimes result in the deaths of many thousands of people.

Infotech and HDR Work Together to Expand BIM Solutions for Civil Infrastructure Projects

Infotech | June 24, 2022

Infotech, a leader in infrastructure construction software solutions, announced today a consulting collaboration with HDR to conduct an industry assessment of its current products and services in order to expand the company’s Building Information Modeling (BIM) offerings and its impact on digital delivery and advancing open data standards. As experts in the use of BIM and digital project delivery for transportation infrastructure, HDR will consult Infotech on the company’s strategic BIM for Infrastructure (BIMFi) plan. Infotech has developed and improved e-Construction solutions that address each phase of the contract lifecycle for 40 years. These solutions automate construction contract processes from estimation to bidding to construction inspection and management in order to provide an open, collaborative environment for effective oversight of an organization’s construction portfolio. Infotech’s solutions, such as Appia® and Bid Express®, and its longstanding position as the official contractor for AASHTOWare Project™, position the company to help accelerate the adoption of BIM within the infrastructure industry. “Infrastructure construction leaders are trying to connect their existing e-Construction solutions with their BIM strategy, and Infotech offers key points of connection between owners and their contractors to capture data that feeds into the BIM design. Understanding BIM and future industry expectations is critical for the success of civil infrastructure projects, and we are excited to collaborate with HDR to enhance our BIMFi strategy.” -Chad Schafer, Infotech Vice President of Revenue. HDR is a full-service engineering, architecture, environmental and construction services firm specializing in both horizontal and vertical infrastructure. In 2022, its transportation program was ranked in the Top 5 design firms in the United States by Engineering News-Record. As a leader in the application and integration of digital delivery methods, they specialize in engineering design, construction management, and data acquisition services. In addition, the firm offers advisory services for enterprise digital workflows to support lifecycle data strategies for managing transportation infrastructure. HDR is currently working with the Federal Highway Administration (FHWA), American Council of Engineering Companies (ACEC), buildingSMART International (bSI), American Association of State Highway and Transportation Officials (AASHTO), and American Roadway Transportation Builders Association (ARTBA) to research, promote and advance digital delivery initiatives in the U.S. transportation industry. The firm is renowned for navigating the changing environment of BIM and digital delivery as well as leveraging enterprise data to advance infrastructure projects. “There are tremendous opportunities in this industry to leverage digital data to inform decisions during the design, construction, operations and maintenance phases. We are strong advocates for open data standards to more efficiently connect the different business areas, which will make it easier to collaborate and provide digital information that can be used to improve the project delivery process from start to finish. Our collaboration with Infotech will help advance these processes.” -Alexa Mitchell, HDR Transportation BIM Program Manager. Infotech and HDR will work together to expand the use of BIM throughout project delivery of civil infrastructure projects by focusing on open data standards to support the asset lifecycle. It is extremely common for data to be siloed across business areas both for the owner and the contractor. Now, when you talk about BIM and digital project delivery, it is all about collaboration and managing the full asset lifecycle. The United States is behind when it comes to open data standards, and together, we are two leaders in the industry focused on advancing the adoption of these best practices to help our industry move forward, faster.” About Infotech Info Tech, Inc., DBA Infotech (Infotech) is a leading SaaS solutions provider for the infrastructure construction industry.
