Architecture

  • Architecture - Functional and Design Components:

The library was built in 1973 as a nonprofit organization that would be jointly funded by the two colleges and administered through a separate board of trustees.   The new building will serve as a three story library opened year round to students and the general public.  Some new special features include enhanced spaces for teaching, personal and group study, scholarly and cultural programming and informal gatherings, an auditorium located on the lower level,  a vibrant gallery space located on the first floor, and a dramatic curtain wall surrounding the new 25,000 SF expansion.  The new library is sure to serve as a wonderful new attraction for the Loyola and Notre Dame College campuses!

A CIP concrete structure supports the four story library for both the existing area and the addition.  The existing CIP concrete building envelope is concealed with a red brick façade giving quite a contrasting look from the newly added expansion which is enclosed by various shades of glass along the four stories of the storefront.  In the existing library space, waffle slabs, CIP exterior concrete walls, and interior CMU structural walls support each above story.  In the addition, CIP concrete slabs were used along with circular CIP concrete columns.  This look compliments the aluminum  curtain walls well, giving the space a radiant, airy look, attracting plenty of daylight for building occupants.

  • Major National Codes: IBC – 2003, NEC, NFPA, ADAAG, ASHRAE, ACI
  • Zoning: R-1, According to Section 4-201(4) of Zoning Code of Baltimore City, educational and cultural institutions: Nonprofit or publicly owned, (ii) Community colleges, colleges, and universities
    or trade schools.
  • Historical Requirements of Building: None
  • Building Envelope:      

The Existing portion of the library is a red brick facade supported by structurally reinforced CIP concrete.  Tinted windows are positioned throughout the brick walls on each floor.  In contrast, the new addition is an aluminum curtain wall structurally supported by CIP concrete slabs and columns.  The types of glass vary for the building storefront.  Each floor consists primarily of a clear glass wall with a green spandrel glass above and a decorative fritted glass below, separated by aluminum mullions.  Aluminum sunshades are also a new feature for the  curtain wall.

The new roof structure consists of a CIP concrete slab sealed by tapered insulation and a white EPDM roof membrane, sloped to drain on metal deck and steel framing.  The outer perimeter of the new roof structure is enclosed by spandrel glass and a metal coping layer that terminates the curtain wall façade.  The existing roof will be replaced by single ply membrane roofing over tapered insulation as well.  The metal fascia panel will remain, surrounding the roof perimeter of the existing roof.  A matching panel will also be installed on a new section of the roof.

Building Statistics II:

Primary Engineering Systems

Construction

  • The Whiting-Turner Contracting Company has been hired for the Construction Manager at Risk for this project, as stated in Building Statistics I.  A Guaranteed Maximum Price Budget is the type of contract being enforced.  Some of the services that will be provided by the CM aside from the traditional building systems include:

 

Temporary Facilities and Controls

 

 

Erosion Control

 

Noise Control

 

Construction Waste Management

 

Protection of Water & Land Resources

 

Rodent and Pest Control

 

Environmental Protection

 

 

Pollution Controlled Facilities

 

Recycling Materials When Possible

  • Construction progress shall be documented in the form of submittals, RFI’s, quality control, coordination with subcontractors and designers, CPM scheduling, special reports, and construction photographs
  • The Loyola/Notre Dame Library has also hired aba Architects, James Posey Associates, and Whitney Bailey Cox & Magnani as architectural, MEP and structural designers on the project. D.W. Kozera, Inc. has also been hired to perform geotechnical work by both the owner and construction manager.

Electrical

  • Electrical distribution throughout the building consists of two electrical closets on each floor, each with a 480/277 V, 225 amp panel, (2) 45 kVA dry type transformers and (2) 150 amp, main circuit breaker, 208/120 V, 3 phase, 4 wire, and 42 pole panelboards.  In the mechanical penthouse, new 480 and 208 V panels were installed as well as a motor control center.  Emergency power is produced by a new 480/277 V 150 kW generator.

Lighting

  • Certain lighting fixtures are unswitched “night light” fixtures.  Other fixtures are on an emergency circuit and are also unswitched.  Branch circuit conductors are connected to new branch circuit homeruns in the existing pull box.  4 #12 + 12G in ¾” conduit go to panel LL, L1, 2, and 3 and 4 #12 + 12G in ¾” conduit go to panel LLA, L1A, L2A, and L3A.  A three way dimmer switch is provided, and is located at the security desk in the new addition.  A connection to the existing lighting circuit for each G type fixture is provided at a 3’-0” length of $#12 wiring for connections as required.  Provide a 16 zone main control unit with four-scene lighting control for auditorium, surface mounted on wall. First, second, and third floor existing and new addition are typical.  Ample daylight is provided via the new glass curtain wall system in the new addition as well.

Mechanical

  • This system consists of four air handling units ranging from 2640 to 38,000 CFM.  Existing AHU are VAV systems, while the two new AHU are VAV and constant volume air with companion return fans.  A 150 ton crane was used for the rigging of AHU #3, #4, and several types of equipment onto the roof.  A constant volume AHU is to serve the special collections room on the third floor (~1000 CFM).  A gas-fired cast-iron sectional boiler (~50 BHP) serves heating and plumbing for the building.  Existing chiller and cooling tower are to remain since they are adequate capacity to support the addition.  Renovation of the existing duct system, new exhaust systems for restrooms and storage rooms, and finned tube radiation are some of the other new mechanical and plumbing features for the new library. 

Structural

  • The existing system is cast-in-place concrete for the exterior load bearing walls with 8” square columns supporting 6” waffle slabs.  The typical bay size for each existing floor is approximately 22’-6”.
  • The new system has 18” diameter circular cast-in-place concrete columns that support the two-way 11’-6” slabs above.  The Bay size for these slabs is not uniform since the shape of the addition is curved.  The columns span 27’-6” in the center of the slabs and vary from a 20’ to 25’ span to the east and west sides of the building.
  • The new foundation is a 12” foundation wall.  The columns are rated at 100 tons compaction a piece, covered by a 1’-6” mat slab.  Auger pressure grouted mini piles were used for foundation support with a design load of 100 tons/pile.

Additional Engineering and Engineering Support Systems

Fire Protection

  • The entire building shall be provided with a complete automatic fire protection system, including wet pipe sprinklers, standpipes and accessories.  Piping arrangement, head locations, and sizing are determined by the contractor, coordinated with structural, architectural, mechanical, and electrical components.  Hydraulic calculations are based on a static pressure of 90 psi and a residual pressure of 55 psi with 995 GPM flowing.  Guards are provided on sprinkler heads in storage rooms, electrical rooms, janitor closets, and also on heads within    7’-6” of finish floor.  High temperature heads are required in areas due to unit heaters, boilers, etc. 

Transportation

  • Two new open stairwells are being installed in the new addition.  They consist of a cast-in-place base elevated by a metal pan stair with concrete tread and tile finish.  The stairwell in the lower level is opened to the floor above, and the stairwell on the second level is also open to the floor above.  All existing cast-in-place concrete stairwells will not be renovated as a value engineering effort.
  • One new elevator will be situated just beyond the south wall of the existing library. (in the new addition area)  The elevator shaft is enclosed by 2 hour fire rated, 8” CMU that is reinforced.  A handicap lift will also be installed in the lower level new addition in the auditorium.  Two elevators will be refurbished in the existing library space.  All elevators are electric traction.  An approved manufacturer will be responsible for installing and servicing elevators for up to two years after project completion.

Telecommunications

  • The Loyola/Notre Dame Library hired Unlimited Support Systems Inc. to complete all of the Information Technology system throughout the new and existing building.  Whiting-Turner is required to coordinate with I.T. and electrical drawings to verify exact locations for AV equipment, loudspeakers, and voice, data, and AV outlets.  These locations should also be confirmed by the architect.  WT is also required to provide, install, terminate, and test category 6 cabling to all designated outlets.  All conduit pathways and penetrations shall be provided and installed by the electrical contractor.  All communication closets are to be lined with ¾” fire retardant plywood backings from 3’-0” above the finished floor to the ceiling.

Special Systems

  • There were no special means of construction for this project.  The addition is not a typical library space since each floor has an open gallery space that is not probable in an ordinary library.  The renovation has a completely different look than the new addition since much of the existing features such as concrete columns, brick walls, and waffle slab ceilings still remained.  Two unique attributes to the new library addition include an auditorium on the lower level, a cyber café on the first floor, and a conference room on the third floor.  The open gallery space on the first floor has slate flooring, and will be furnished with sofas, chairs, and end tables, rather than library desks and chairs.  This space will provide a more informal setting with a great view of both college campuses.
