A great deal of hubbub has surrounded the luxury real estate market in Downtown San Francisco in recent months. Newly completed is La Maison, a 28-unit luxury condominium building located at 241 10th Street between Howard and Folsom. Epitomizing comfort and sophistication, this 23,570 square-foot mixed-use residential structure offers a variety of one- and two-bedroom contemporary floorplans ranging from 518 square feet to 992 square feet, each individually custom designed to offer a unique living experience. Structural design was performed by Nishkian Monks. The structure is four stories of wood framing over one story of concrete construction (Type VA over Type IA). The wood framing consists of I-joist and glulam floor/roof framing with wood shear walls. The above grade post-tensioned concrete podium separates the residential units from the office/retail and parking spaces below. The structural foundation is an at-grade mat foundation.
The recently completed new commercial building, The Palisade, illustrates the changing tide in the fastest growing and highest density of residential neighborhoods on the west end of Bozeman. Nishkian Monks participated in the project as the structural engineer of record, working directly with Bitnar Architects and general contractor Langlas & Associates. Developed by Paine Group, Inc., The Palisade is a 6,600-square-foot commercial building located at 630 Boardwalk Avenue. The structure is located at a gently sloping site. Above grade, the exterior and interior walls are of light-gage metal stud construction with thin set brick veneer at the exterior walls. The roof framing is accomplished with pre-engineered open web steel trusses. The building is founded on conventional concrete strip and spread footings with a slab-on-grade at the ground level.
The renovation of the old Harrington and Story warehouse at 212 South Wallace Avenue in Bozeman has been no ordinary task. In the 1900s the property used to be the Chicago, Milwaukee Co. East Main Depot where asbestos ore was stored for milling prior to being transported elsewhere. Since then, anthophyllite asbestos contaminants have been found in the soils on the site and on surrounding private property where asbestos ore was spread or used as fill. Extensive abatement and clean-up of the soils along South Wallace was performed in 2003 and 2009. Further clean-up was performed in 2014 prior to the demolition of the old warehouse and remodeling of the site. Although the process of removing the asbestos took longer than originally planned, the transformation was worth it.
The old historic structure was a combination of heavy timber beam and column floor construction to hold large commercial loading at the ground level, and light-frame wood stud construction at the upper levels. The roof trusses span 60 feet, and have no interior supports. The total building area of the remodel is approximately 18,600 square feet (1,723 square meters). The renovation project was built by general contractor Langlas & Associates with architectural design by Intrinsik Architecture and Nishkian Monks serving as structural engineers of record. Since the building went through a complete renovation from top to bottom, the City of Bozeman Building Department required that the structure be analyzed and proven to meet the performance requirement of the current building code. The structural scope of services, as performed by Nishkian Monks, included engineering of new window openings in exterior walls; analyzing and strengthening of existing lateral system to meet current code requirements; removing 1/3 of existing structural columns and introducing new load path to remaining or new columns to provide increased flexibility for future tenants; analyzing existing roof trusses for new loads and fixing damaged truss web members; adding a new elevator shaft and two new stair towers; and adding concrete exterior light-well, patio, and ramps.
