National Aquarium In Baltimore Blacktip Reef Exhibit

National Aquarium In Baltimore NAIB - Wings on the Water Renovation - Black Tip Reef.JPG
Project Overview: 
McLaren performed structural investigation, design, and construction phase services as part of the A/E team for the complete restoration and renovation of a 260,000 gallon salt water tank. The crown jewel of the National Aquarium’s Pier 3 Building, the “Blacktip Reef Exhibit” includes a large curved acrylic viewing panel, cantilevered viewing gallery with glass handrails, and was constructed without disturbing everyday operations of the aquarium.
McLaren's Role: 
Challenged with performing the investigation and design of the renovated space while the exhibit area was full of water, McLaren utilized in house dive teams to gather information and extract core samples of the existing concrete. Using 3-D finite element structural modeling and historical investigations and analysis, McLaren prepared bid and construction documents for the renovations that were required to transform the exhibit into the new “Blacktip Reef Exhibit”. Significant renovations included the removal of an existing column and slab system to permit the construction of a new cantilevered viewing gallery and removal of large parts of the original tank to accommodate the 27’ x 8’ tall x 3" thick curved acrylic viewing panel. Due to the open nature of the Pier 3 Building, McLaren worked closely with a scaffolding company to enable a temporary “lid” to be installed over the exhibit to minimize noise, dust, and visibility to the rest of the building during the construction phase.

Towson Square (formerly Towson Circle III)

Towson Circle.JPG
Project Overview: 
Towson Square is a mixed-use urban redevelopment project including a 320,000 square foot building containing a 15 screen multiplex cinema atop a three-level, 850 car parking garage and 35,000 square feet of retail. McLaren was tasked with fitting the 850 car garage on a site that was constrained by three (3) property lines, an existing cemetery and rock below grade, as well as the design of two (2) connected retail sites with an exterior elevator and access tunnel.
McLaren's Role: 
Geotechnical – In-place soil testing techniques were utilized by McLaren, allowing for the application of ground improvement techniques to change from 6,000/2,000 psf soil to 10,000 psf soil across the site. Structural – While the theater portion of the structure was designed under a separate contract, McLaren was challenged to design an 850 car parking structure that serves as a foundation for the theater and accommodated theater egress and services. The project included five (5) external egress stair towers and four (4) separate elevators, to accommodate the theater and 11,500 square feet of retail contained within the main building.

1900 Arch Street

1900 Arch Street Light Gage Building.jpg
Project Overview: 
1900 Arch Street is a 14 story, 3-tiered mixed-use building in downtown Philadelphia, comprising 330,000 square feet of floor area and 248 residential units. Designed and constructed using a pre-engineered, pre-fabricated light gage wall and floor panel system, 1900 Arch street is the tallest pre-fabricated load bearing metal panel structure built to date; with an impressive 13 stories of load bearing wall panels.
McLaren's Role: 
McLaren was called upon well after the Design Development phase to perform significant structural redesign, without adversely impacting architecture, to bring the project in line with budget and time constraints. Highlights of the structural redesign include a secant pile shored excavation and foundation wall system, the steel transfer level below the pre-fabricated load bearing wall panels, an 8 inch deep Comslab floor deck permitting 26 foot clear slab spans, preparation of shop drawings for pre-fabricated light gage load bearing wall panels for the interior of the structure, and an extensive green roof encompassing 2/3 of the roof area. By using a pre-engineered, pre-fabricated light gage wall and floor panel system; McLaren was able to facilitate a shorter construction period and gain permits for an earlier start time for all interior trades.

LIRR Jamaica Station Headquarters Structural Rehabilitation

LIRR Jamaica Station Headquarters Structural Rehabilitation .jpg
Project Overview: 
McLaren provided structural inspection, evaluation, and design services for the rehabilitation of exterior elements of the historic LIRR. Completed in 1913 with great fanfare, the Jamaica Station building’s restoration not only protects this valuable asset against further deterioration, but also highlights its historical and cultural significance. Since the building is eligible to be listed on the National Register, rehabilitation work was performed with the approval of the New York SHPO.
McLaren's Role: 
McLaren performed a detailed condition inspection of the Jamaica Station Building’s exterior, including all concrete, terra cotta, sheet metal, cast iron, brick, granite, and wood façade elements. In order to allow the building to maintain 100% functionality, a comprehensive staging plan was developed for the inspections. Accessing the facades was a key challenge; a specialized rigging contractor was utilized for these. Inspection findings were tabulated into a rehabilitation report. Following the inspection, McLaren began rehabilitation designs for the deteriorated structural elements. New lighting and coatings was also provided. Bid Phase Support was provided after construction documents were delivered.

Project Overview: 
Arundel Mills Maryland Live! Casino (Maryland Live!) is a 2 million sq. ft. structure and is the largest casino and entertainment venue on the East Coast. This project called for a fast track design process that included a construction phase that was completed in 17 months.
McLaren's Role: 
Structural engineering services included design of the foundation system, structural steel for casino, porte cochere, and central utility plant superstructures, precast parking garage layout (with precast concrete columns, structural steel for level 2, and precast concrete for levels 3 through 7), and review of calculations and shop drawings for precast concrete garage above. Design also included structural support of 2 LED (23’x150’ at north and south façade) signs and Static Signage on east and west facades of the building. McLaren was responsible for full subsurface investigation including testing and inspection services during ground improvement operations and foundation inspection.
