Trailway Design-Build - Maybrook

From the Manhattan Greenway Trail to Walkway Over the Hudson and now the Maybrook Trail, McLaren has been a part of the nation’s longest multi-use state trail, the 750-mile Empire State Trail. A source of NY recreation, economic development and tourism, the new recreational trail runs up the state from New York City through the Hudson and Champlain Valleys to Canada, and across from Albany to Buffalo along the Erie Canal.

Now officially open to the public, McLaren worked with MetroNorth to engineer the final link in the trail system, a 23-mile connector between Hopewell Junction and Brewster called the Maybrook Trailway. This design-build project repurposed a portion of the previous two-track Beacon line corridor into a 10-foot wide shared-use bicycle and pedestrian path. After removing one track, the trail now follows the alignment of the former railroad line while the other inactive track remains in place for potential future rail service. McLaren designed all aspects of the trailway providing bridge engineering, civil engineering, geotechnical engineering, structural engineering, and the surveying services needed to render the Rail Trail complete and fully functional.

TSX Broadway

Times Square is saying goodbye to 2020 with a fully virtual ball drop this New Year’s Eve. When in-person celebrations do return to NYC, TSX, the new luxury hotel currently under construction, will offer unparalleled views of the excitement for its guests from inside their 5-star rooms. Soaring high above Times Square, TSX Broadway will be a 46-story tower of retail, entertainment space, outdoor stage, and hotel accommodations that promise to revolutionize the city’s NYE celebrations once open in 2022.

McLaren’s construction engineering team is helping bring the project to life by providing crane engineering, connection design, detailing, connected model support, and demolition engineering. Once complete, each of the hotel’s 669 rooms will have epic views of Times Square through expansive floor-to-ceiling glass windows, including 30 prime “Ball Drop Suites”.

NAC Safety Committee Chair Ken Arnold

We are advised by some of the industry’s best. McLaren Board Director, Ken Arnold, P.E. was recently appointed as the Safety Committee Chair for the elite National Academy of Construction (NAC). Composed of 360 distinguished leaders from every segment of the engineering and construction industry, NAC brings together individuals who have made extraordinary contributions to the built environment.

Ken brings his experience, knowledge and expertise to help steer McLaren’s continued growth and success. He is the founder of Paragon Engineering Services, an oil and gas project management and engineering services firm, which was sold to AMEC in 2005. With over 55 years of experience in facilities engineering design and project management, he has worked on both onshore and offshore projects throughout the world. Ken also serves as a senior technical advisor to Worley and to Oxy Oil and Gas.

Column Free Event Space - The Hall

A partially existing post-tensioned concrete parking deck has been transformed into a 3-level, 75,000-square-foot, steel-framed entertainment superstructure dubbed THE HALL at LIVE! A dynamic addition to the existing Live! Maryland complex, THE HALL was designed as a large-scale, column-free event space that is slated to feature top acts. Using a strategic combination of composite steel framing for the floor spaces and long-span transfer trusses at the roof, McLaren was able to construct a world-class venue without any disruptions to daily hotel and casino operations.

The main level offers 30,000 square foot of flexible seating configuration space. Above, a 12,000 square foot “loge” mezzanine level with traditional fixed seating boxes flanks the stage area on both sides of the performance space. To accommodate the column-free mandate, the loge level seating employs a clever framing arrangement of cascading cantilevers. Above, 15,000 square foot of tiered basin VIP level seating hangs from a steel truss roof system that clear spans the entire 180 foot-wide performance space.

Drawing upon our extensive entertainment experience around the world, our Maryland team also provided design assistance to the state-of-the-art 7,000 square foot flexible theater grid, catwalk, and rigging support system. Read more about the project.

Facade Inspections from land, sky and ropes

Inspecting facades from land, sky and ropes! Most large cities across the nation have ordinances requiring periodic envelope inspections of buildings, particularly close-up, hands-on reviews of taller street-facing facades to maintain safety and ensure proper repair and maintenance. McLaren recently performed detailed facade inspections, getting a full-picture story of the building’s envelope health using binoculars, drones, and rope drops.

Our in-house SPRAT Level 1 certified rope access engineers, dropped down for a 300’ rappel from the roof, supervised by BNW’s SPRAT Level 3 riggers. Conducting hands-on facade inspections via rope is not only more adrenaline pumping, but also more efficient and less expensive than traditional scaffold-drop inspections from a motorized rig. To help, inspectors on the ground used binoculars to scan the facade wall and from the sky, drones provided an additional cross-reference detailed view, taking high-definition photographs (40 megapixel from close range) of the entire building envelope. Y Bird Airways operated the inspection drones and post-processed them to create a composite photo catalog of the building. The technique allowed inspectors to zoom in on areas of concern that were not accessible during rope drop operations, helping piece together an accurate, multi-angle building envelope investigation.

Bathymetric Mapping of California Reservoirs

Our surveyors have been active performing cutting-edge bathymetric mapping to investigate seafloor conditions and capacities of several California reservoirs. Utilizing our Multibeam Echosounder (MBES) and integrated mobile LiDAR system, McLaren conducted highly-detailed 3D scans above and below the water. The MBES emits sound waves in a fan shape beneath the boat’s hull using beamforming to extract directional information from the returning soundwaves. Several transducers allow for a large swath of area to be surveyed from a single ping, making the hydrographic survey fast and more accurate.

Simultaneously, the LiDAR technology utilizes remote sensing in the form of a pulsed laser to measure ranges to complete the full 3D model of each reservoir. This bathymetric mapping method for acquiring the data sources increases the accuracy of the water volume capacity calculations while also identifying potential erosion or sediment deposit related issues.

Heavy Lifting Structural Analysis

For heavy lifting companies, no two jobs are ever the same. To know what their equipment can safely do when situations vary, structural capacities for heavy lifting equipment must be established. Recently McLaren worked with Rountree Transport & Rigging on a specialized review of their Hydra-Slide Ltd. System that was used to move a 144,440 lb transformer into position at a substation for a 70 MW solar farm. The transformer’s final location, an elevated concrete foundation located in a 27 foot x 40 foot concrete oil containment pit, made it difficult for crane positioning.  The oil containment pit bottom did not have the capacity to support the crane outriggers and other electrical equipment in the substation limited crane access.

Our Florida team performed a structural analysis on the custom Hydra-Slide Ltd. System and determined it would be feasible for the system to span 20 feet over the oil containment pit, acting as temporary steel support rails to slide the heavy transformer into place. Hydraulic pistons clamped to the top of the two lubricated support rails enabled Rountree Transport & Rigging to safely pull the heavy load into its final position on the elevated concrete foundation.

Aspiring Engineers Learn About Engineering

Victoria Christini, PE, Sr. Associate at McLaren recently spoke to aspiring engineers at AAUW’s and New York State Society of Professional Engineers’ 11th Annual Engineering Conference. Vicki shared her career path with the students, focusing on her specialized expertise in bridge, subway, marine, and ferry engineering. The panel made up of various engineering professionals, discussed the important role engineers play in solving problems and the impact they make across the nation’s communities.

Restored Fountain of the Fairs Open

When the 1964 World’s Fair made its way to Flushing Meadows Corona Park in Queens NY, an iconic Unisphere took center stage to symbolize the world’s entrance into the space age. Between this massive steel earth and Fountain of the Planets, lies the historic reflecting pools and Fountain of the Fairs. These water features were seriously damaged during Hurricane Sandy and in disrepair until a recent $6.8 million upgrade restored them to their full glory.

McLaren’s multidisciplinary teams provided survey, civil engineering, geotechnical engineering, structural engineering and construction support for the renovation and adaptive re-use of the historic landmark reimagined by NYC Parks.

To help keep the original footprint, dimensions, and design but integrate new resilient infrastructure and additional water features, our team provided detailed condition assessments, geotechnical investigations, structural analysis, and design for the new framed concrete slab over the existing pools. We also engineered various water supply and drainage/utility structures, designing the storm sewer system and subsurface drainage layouts.

The restored Fountains of the Fairs now includes additional community water features and recreation areas, ready to draw visitors from around NYC and the world.
