National Aquarium in Baltimore Expansion
Location: Baltimore City, Maryland
Client: Baltimore City & the National Aquarium in Baltimore (NAIB)
JMT assisted our client with a new pedestrian bridge and
provided additional engineering and inspection services related to
pier structures in Baltimore's Inner Harbor.
JMT was initially requested by the the City of Baltimore
Department of Public Works to provide the design, prepare bid
documents and oversee the construction of a new pedestrian bridge
between Piers Number 3 and 4, a major retail and commercial section
within Baltimore's Inner Harbor area.
The project schedule was ambitious in that the construction was
to be complete by the July 4th holiday. JMT staff
worked closely with City staff, NAIB and a local developer.
In just a few weeks, JMT developed the design to a point that
materials could be obtained through standard City procurement,
allowing construction materials to be on-site upon award of the
construction contract. In the following weeks JMT completed the
design, obtained permits (City, State and Federal) and with the
City let the Contract for Bid.
JMT continued working with NAIB providing a wide variety of
engineering services including project management, utility
coordination, project site work, environmental analysis, structural
analysis and inspection, geotechnical, and design services. NAIB's
Pier 3 facility, which is located within a bulkhead, was
constructed in the early 1900s and needed to undergo a thorough
inspection. JMT performed an inspection of the entire
bulkhead, both below and above the waterline. Based on the
inspection data, an in-depth structural analysis determined that
part of the bulkhead would need to be rehabilitated due to
deterioration and to support increased loads. JMT completed
and managed all construction documents for this and all other
tasks. Additionally, an area of concern was the lack of information
regarding the location of utilities on and around the pier.
JMT located all available utility and construction plans for the
pier, and prepared topographic survey and test pit information.
Subsequently, JMT prepared the Civil Site and Structural design
for the NAIB expansion and Pier 3 reconstruction. Design work
included erosion and sediment control, stormwater management,
grading, drainage, footings and foundations for miscellaneous
structures outside of the building lines, and field surveys.
JMT coordinated the work of the geotechnical sub consultant and
prepared foundation analysis and recommendations. JMT coordinated
all permit issues associated with the project. Work included
setting up coordination and informational meetings with various
design team members and agencies during the design phase,
assembling permit application packages and submittal of the permit
applications on behalf of NAIB. The final hardscape consisted of
over 62,000 square feet of pavers, plated areas with seat walls,
vehicular and pedestrian pavement sections, and signage and
