Overview Founded in 1996 An engineering design and consulting firm 3400 N. Charles St (Latrobe Hall) Baltimore, MD 21218 410 – 516 – 1234 [email protected]

Proposal Outline  Restoration

of the Historic Leigh Street Armory

 Construction

Building

of the New Office

Armory Restoration  Provide

bracing to maintain historic façade  Replace structural masonry system with a steel moment frame load resisting system  Install an open web steel joists floor system to support the concrete floor slab  Restore all masonry walls as non-structural elements  Replace all doors and windows  Install new steel roof truss system to maintain original building aesthetics while improving structural integrity  Comply with Current Code Requirements

Armory History  Built

in 1895

 Served

as headquarters for the First Battalion Virginia Volunteers Infantry, Richmond’s first African American regiment

 Used

as a social center, housing facility, recreation hall, elementary school, junior and high school

Frame Design  Steel

Moment Frame

– Does not interfere with Building Function – Reduce member size and longer spans – Reduction in Construction Time  Member

Placement

Member Placement

Floor Joist System: Open Web Steel Joist Long

Spans Light Weight System Lack of Large Concentrated Live Loads Thinner Concrete Floor Slab

Roof System  Retained

Historic Hip and Gable roof

shape  Replaced old wood Hip members with Steel

Picture of Roof System

Renovating the Armory  Cleaning

the façade  Managing Efflorescence (phosphoric acid)  Examining Joints and Sealants  Attaching lintel sections at each floor slab for additional lateral support

Current Code Requirements  Structural  Fire

Safety  Accessibility

New Office Building  Construct

a 61’x60’ 4-story office building in lot adjacent to Armory  Create exterior façade to complement the Armory  Provide Structural Steel Moment Frame Support System  Install an open web steel joists floor system to support the concrete floor slab  Comply with Code Requirements

Engineering the Barriers: All in One  Thermal:

Steel Lintel Issue

 Water:

Warm-In-Winter side, Perm-ABarrier

 Air:

Warm In Winter side

 Vapor:

None.

Project Timeline  Investigation

~ 1 week  Schematic Design ~ 1 week  Design Development ~ 1 week  Construction Document ~ 3 weeks  Construction Administration ~ 23 months

Project Budget Estimated Total Project Cost : $ 5 million •

Armory Restoration ~ $ 2 million

•

New Building ~ $ 3 million

•

CS, Inc Schematic Design ~ $12,205

Conclusion  Efficiency

– Our structure uses an intelligent moment frame design coupled with a smart open webbed joist floor system.  Economical

– This will minimize material cost, saving money. The quick erection time shall reduce capital cost.  Elegance

– Our Armory will maintain the authenticity of its historic fortress like appearance, and the New Building shall complement the aesthetic mastery of the Armory.
