0.1 Project Description For the first part of the semester both sections of the ARC 302 studio will be working on the same project - The ACSA 2010-2011 Steel Design Student Competition. There are two Categories offered in the competition. For the purpose of this studio, Category II - Open Submission is selected for a greater amount of flexibility. ARC302 students should adhere to the submission requirements of the competition. For more information related to this competition. The US National Lacrosse Center, a 75,000 SF building to be located in Baltimore, MD, is selected as the project for the Open Category. Lacrosse is the oldest game native to the North American continent and is now one of the fastest growing sports in the country. Maryland is the home of the national headquarters of US Lacrosse, the national governing body of men’s and women’s lacrosse. US Lacrosse desires to construct a new facility, US National Lacrosse Center, at the Inner Harbor area in downtown Baltimore. This will be the only National Lacrosse Center in the world. -“Steel should be used as the primary structural material with special emphasis placed on innovation in steel design”. -The design must look, feel, and represent the characteristics of the sport. -The facility shall provide the resources that the sport needs to prosper. -Provide an experience that is educational, informative and unique to the sport of lacrosse. -Take advantage of the site as an opportunity to gather together & celebrate the sport.

Site Analysis

1.1 Context The site for the proposed US National Lacrosse Center is located in the Baltimore Harbor. It is in close proximity to the Baltimore Aquarium and other such tourist and commercial ventures. It acts as an anchor between this commercial area and the historic industrial area across the water.

The site, being right on the water, has tremendous view of the harbor and its activities. 43% of the view is occupied by commercial area such as the inner harbor restaurants and aquarium. 34% of the view focuses on the industrial area across the harbor including the iconic Domino Sugar factory, and 23% of the view is focused northeast to the predominantly residential area.

In an effort to better understand the scope of green space in Baltimore, a typological study was conducted, comparing Baltimore to other port cities. A three square mile sample was taken and analyzed from Boston and Copenhagen. This was able to show the inadequacies of the green space in Baltimore. It can be deduced that proposal for the given site must make use of some sort of public green space for the city of Baltimore.

1.5 Circulation Methods In an attempt to understand how people move through Baltimore, this study breaks down the circulation by pedestrian, vehicular, mixed, and private types. It becomes apparent that the site falls in the zone most frequented by pedestrians and the further away from the water the more vehicular traffic there is.

1.4 Public Transportation Studying the public transportation system of Baltimore can provide some insight on how people will be arriving on site. There are a number of options for the MTA bus most likely used primarily by local residents. The MTA metro stops in the heart of downtown near the inner harbor. There has also been talk be the city to develop some areas as transit oriented development zones. This would increase the number of people in the area of the site making more acessable.

Siting/Massing Options

2.1 Scheme One

pros -clear line of site to harbor from president street -field and headquarters are visible from the harbor -intuitive circulation in and out of site cons -field is vulnerable to wind -parking is great distance from entrance -limited expansion north, south, and west of field

2.2 Scheme Two

pros -oriented towards major harbor attractions -form is strictly derived from shore-line -provide most views of harbor -emphasizes the museum component by elevating on a more solid volume -adequate area available for future development in northwest corner cons -future development is limited by vehiclular acccess -field is vulnerable to wind

2.3 Scheme Three

pros -provides sufficient area for future development -lacrosse field is sheltered from the summer and winter winds cons -poor solar orientation i.e. north south scheme -parking is great distance from entrance -limited expansion north, south, and west of field

4.1 Architectural Narrative

Our site is very much an edge condition. It is situated on the boundary between old and new. It is involved in a conversation with the water just as much as it is with the land it engages. On one side, the city is commercial oriented, another residential, and yet across the water is the industrial epicenter. Our proposal will act as a threshold between these typologies providing a meeting place for all. Similarly, lacrosse is a sport dealing with edge conditions. It is overshadowed by more popularized American sports, however the it is experiencing tremendous growth and is in a position where it must bridge the gap between its history and its promising future as a more prominent American sport. Public infrastructure has historically been a catalyst for economic development and social capital. One such example is the use of green space and urban plazas to effectively encouraging social interactions and forge stronger community ties. In compliance with the Baltimore City master plan aimed at battling population loss and concentrated poverty, our proposal will seek to establish such an infrastructure. The proposed urban fabric will set up a strong orthogonal grid only to be broken by an off axis green way connecting the main land to our proposal, while providing sufficient green space for the public that is otherwise lacking in Baltimore. The US National Lacrosse Center will be sited perpendicular to this green way, though elevated so as to allow the public space to flow to the harbor.

4.2 Structural Narrative As steel is the main focus of the competition we designed the US National Lacrosse Center to celebrate the building material. The design does this in three ways.

Finally, the structure takes on a more expressive form, differing from the normal boxed truss in that the center turns inward transferring the load to the floor diaphragm.

Secondly, the structure is brought to the outside of the building envelope making it more prominent on the exterior while freeing up space on the interior.

First the large steel truss is elevated. Not only does this allow for the green way to flow under the building in compliance with the architectural intent, but it also draws attention to the seemingly elevated and unsupported steel.

4.4 Mechanical The building is broken up in to two zones. Zone One on the west side is controlled by Air Handling Unit One and Zone Two on the east is controlled by Air Handling Unit Two. The chillers are to be housed on the roof and the air handling units are in the basement with the boilers. We are employing a sub-floor air distribution system utilizing low density air flow. We have put the air return in the ceiling, allowing for continuous circulation and optimum temperature control.
