Canal System in NYS Reopening - Underwater Inspections

You can go anywhere in the world from the NYS Canal System. The waterway that opened America to the west is reopening little by little. McLaren is providing underwater inspections, mechanical and electrical inspections, load rating analysis and hydrographic surveying for the New York State Canal Corporation’s Eastern Division. The Canal system fully opened to Lake Champlain last week.

Building Envelope Construction on NYC's Virgin Hotel

Building Envelope construction on NYC’s Virgin Hotel is nearing completion. Designed by Stantec and developed by Lam Group, this 40+ story hotel features a beautifully deconstructed tower covered in a pixelated pattern of subtle opaque glazed glass panels, bringing a contemporary aesthetic to the historic NoMad neighborhood.

For the reinforced concrete tower, McLaren’s facade team worked closely with the Italian firm AZA INT Corporation to deliver a stunning custom tower curtain wall system. In order to create a flush design with superior energy efficiency, our engineers utilized a prefabricated WICONA glazing system, not typically seen in the US. All of the glass load is supported on the exterior of the thermal break zone webbing which is made from recycled polyamide. This offers the building envelope a high level of energy efficiency and low thermal bridging that meet NYC’s strict sustainable construction goals.

Student Housing on its way up at Institute of Technology

Stevens Institute of Technology is looking to the future with one of its most ambitious infrastructure projects. Construction of The Student Housing and University Center is set to redefine its campus community and culture. Two new residential towers, one 16 stories and the other 18 stories, that will provide much needed campus housing options for nearly 1,000 students once completed and safe.

McLaren’s Construction Engineering team is working with Orange County Ironworks, LLC Works on the steel connection design and erection means and methods for the two-truss pedestrian bridge that will connect the two student housing towers via the third floor.

A unique challenge our team had to overcome when erecting these trusses was the inability to use shoring towers to temporarily support the truss chords as it was being erected and installed. Instead, we installed the top chords first then the remaining members in a particular sequence.

Find out more about how we are helping construct this glass enclosed bridge that will one day provide the New Jersey university with stunning views of Hudson River and mid-town Manhattan, here.

What is a Bathymetric Survey?

A bathymetric survey (sometimes referred to as a fathometric survey) is a type of hydrographic or water-based survey that maps the depths and shapes of underwater terrain to illustrate the land that lies below. Bathymetric surveyors work to obtain an exact representative image of the seabed and identify elevations, anomalies and the presence of scour around submerged structures. They also analyze and define the surrounding shorelines, tides, currents, and waves to create a better model of the area features overall.

Our hydrographic survey vessels are also equipped to perform singlebeam, side scan sonar, magnetometer, sub-bottom profiler, and sampling.

When performing bathymetric surveys in deeper waters for marine construction projects like dredging or offshore energy, McLaren typically utilizes multibeam survey technology aboard a custom vessel. Long ago, bathymetric survey techniques used pre-measured heavy ropes lowered over a ship’s side (lead lines), but today, technology like multibeam echosounders safely attach to a manned or unmanned vessel to conduct accurate and precise measurements. The multibeam system pings sound waves in a fan shape of narrow adjacent beams that bounce off the seabed and return to calculate the distance to the seafloor.

Bathymetric Survey in Shallow Water

Many bathymetric surveys for projects like shoreline stabilization, engineering design, or infrastructure remediation, require bathymetric surveys to be performed in very shallow waters inaccessible by traditional vessels. Conducting these surveys in shallow water can be extremely difficult in terms of accessibility, space, fast-flowing currents, submerged debris, navigational hazards, or environmentally sensitive habitats. To mitigate these effects, McLaren surveyors use cutting edge tools like remote-control Unmanned Surface Vessel (USV) technology. This state-of-the-art equipment conducts precise bathymetric surveys in shallow water safely and efficiently.

Topographic mapping benefiting a bathymetric survey.

For these shallow water surveys, our hydrographic crews have been using high-tech equipment including Teledyne Z-boats and HyDrone Unmanned Surface Vessels (USV) combined with either a multibeam or singlebeam echosounder, positioned with RTK-GNSS. For projects such as the survey of bridges and nearshore embankments, topographic mapping is often needed in addition to a bathymetric survey. For this, McLaren uses custom solutions tailored to each project, that may include the use of small Unmanned Aerial Systems (sUAS) / Drones, mobile lidar, or terrestrial 3D laser scanners.

Bathymetric Survey Application

McLaren’s bathymetric survey work has been an integral part of the development of many bridge and marine projects like Domino Park, Weehawken Pier, Westchester Bundled Bridges, NYC Ferry system and the development of Off-shore Wind facilities in the United States. “Hydrographic surveys are one of the first steps to determine if a project in or near water is conceptually and physically feasible,” says Steven MacDonald PLS, P.Eng., McLaren Albany Regional Director & Geomatics Principal. “In addition to large offshore or near-shore construction projects, these surveys can also be used as analysis for flood inundation, scour and stabilization, water-quality studies, waterfront facility inspections, habitat mapping, dam removals and environmental spills.”

He is an industry leader who possesses a dynamic blend of renewables, geosciences and environmental expertise. Steven has over 15 years of experience delivering high resolution hydrographic, geophysical, geotechnical, cadastral, and environmental surveys with specialties in Offshore Energy, Nautical Charting, Emergency Response, and 4D full life span monitoring.

Warehouse Conversion - The Pennant

Work on the soon-to-be five-story waterfront residential building, The Pennant, is currently underway in the historic Fell’s Point neighborhood of Baltimore, Maryland. McLaren is working with architecture firm Hord Coplan Macht and general contractors Chesapeake Contracting Group to provide structural and marine engineering for this part adaptive reuse, part new construction apartment and townhome complex developed by Elm Street Development.

The planned 285-unit structure warehouse conversion project will repurpose a section of the site’s existing two-story Wolfe Street warehouse to a parking garage, fitness center, residential entry and storage space. A three-story addition will be constructed above the existing levels and be set back from warehouse parapet. Adjacent, a 5-story, 307,500 sf addition will be erected on existing foundations to house a leasing center, main amenity space, and residential units.

McLaren’s marine division’s in-house P.E. divers performed above and under-water inspections of the bulkhead system and concrete platform lining the warehouse conversion development. The team made recommendations to increase the longevity of the existing system and designed a new bulkhead system, reusing the existing tie-backs and piles.
