NYC Department of Environmental Protection (NYC DEP)’s Post

Imagine trying to replace a bridge that hundreds of thousands of New Yorkers regularly rely on to enter Manhattan. Not easy at all. So, how do you deliver on a project that impacts so many stakeholders? New York State DOT tried something different and used digital twin processes, which helped the team share project plans with over 180 reviewers across 15 agencies and address public concerns, which would not have been possible with conventional methods.

How Are Super Tall Buildings Aging? https://ow.ly/yXxv50SEskN Learn more about the structural issues faced by some of New York City's super tall buildings, ten years after the construction boom in the city.

Performance-based zoning came next, allowing a greater mix of uses and flexibility in development scale — in return for more open space or other benefits to the community where the development takes place. https://lnkd.in/eNFu2rnQ #planning #zoning #mixeduse #development #policy

Out of the Archives: This photo taken May 23, 1913, in City Water Tunnel No. 1 reappeared 15 years later in a New York Times article about the approaching start of Water Tunnel No. 2 construction. It shows mucking operations, with workers loading excavated rock into wheelbarrows. The 2nd tunnel would provide more water and better pressure to Brooklyn, Queens, and Staten Island, and increase capacity for the future Delaware system. Both are deep pressure tunnels in bedrock, built with minimal disruption to the world above. As the article states: "Few people on the surface will know what goes on beneath them, any more than they were aware of the creation of the first city tunnel that today carries hundreds of millions of gallons of water under the subways and vaults and cellars of Manhattan Island."

Found an older article directly related to the unusual high-density, multi-residential development that inspired a post a few weeks ago ("Navigating Zoning Land Mines"). https://lnkd.in/eyxWBa4m The article mentions that the community of Marda Loop pushed back with a 1,000-signature petition. Interestingly, I referenced the Marda Loop Area Redevelopment Plan (ARP). Since the development was approved, the ARP maps and wording were modified to show the creep of high-density development into the previously designated "Low Density, Residential" section of the roadway (previously designated east of 19 Street SW). This shows how malleable long-term ARPs are in response to pressure from developers and changing market forces. The article indicates how the DC or Direct Control zoning is a flexible used in land use redesignation.

The ongoing US 101 / University Avenue Interchange Improvements project in East Palo Alto is a comprehensive endeavor by MCM Construction and the City of East Palo Alto. It involves constructing a pedestrian overcrossing above US 101, connecting it with a Class I bikeway that extends to Woodland Avenue in the west and Donohoe Street in the east. Additionally, the project includes widening the US 101 southbound off-ramp to University Avenue, reconstructing the northbound off-ramp, and renovating a section of University Avenue between US 101 and Woodland Avenue. Alongside these infrastructure developments, adjustments to existing traffic signals and the installation of new street lights are planned to enhance safety and efficiency. #sierrageotech #geotechnicalengineering #civilengineer #california #materialstesting

How Material Science Makes or Breaks a Build   In this episode of Build Better Homes, we dissect a real-world building failure case in Alaska from Nate’s own professional experience. Nate MacIntyre(@n.macintyre on IG) is a friend I’ve worked with for years and is an expert on building envelope and construction defects.   Explore how dissecting building mishaps can improve future construction designs and prevent disasters.   #buildbetterhomes #buildingfailure #materialscience #extremeweather #buildingphysics #modulusofelasticity #Alaskanconstruction #constructionfails #preventativemaintenance #buildingresearch

Topographic surveys are the backbone of successful infrastructure and road construction projects. They provide crucial data on the land's elevation, slopes, and natural features, ensuring safe and efficient designs. Without them, our roads and buildings would be at risk of failure. #surveying #construction🏗️ #TopographicSurveys #InfrastructureProjects #RoadConstruction #SafeDesigns #CivilEngineering #ConstructionIndustry #SurveyingServices

Designing a mountain road isn't for the faint of heart. It's great to see my friend and colleague, Tammy Heffron, explain what it takes! Check out this new video from the Wall Street Journal that delves into why these roads are so complex and difficult to design.  https://lnkd.in/g55JXrPn

The construction of large and small scale residential and commercial buildings requires accurate setout to eliminate any complications and issues with the build 🏗 Utilising a computer prepared layout and generally combined with a boundary re-establishment survey, we can ensure exact setbacks and boundary clearances of the proposed building ✅ #localsworkingwithlocalsforlocals #quantumsurveys #landsurveying #spaticalscience #perthsurveyor #geraldtonsurveyors #geraldton #westernaustralia
