St. Francis Medical Center Expansion
Francis Health Services /Centura Health
The facility is a new five-story, 168,000 square foot addition to the existing Medical Center that was also designed by RTA/MGA in 2005. The facility includes operating rooms, neonatal intensive care units and a new emergency department and is designed for two future floors of patient rooms at approximately 26,600 gross square feet per floor. The structural construction materials are similar to the original construction with composite concrete slabs on steel frame roof and floors. The lower garden level parking and floor under the north ED is precast concrete double tee floors with precast girders and columns. The stair and elevator cores are precast wall panels that are the lateral force resisting elements for the addition. Foundations are deep, concrete drilled piers. Construction started in the spring of 2017 and was completed in the spring of 2019. The project was a standard Design-Bid-Builddelivery method.
The Meadows at Castle Rock, Town Center Three
This project is a three-story, mixed-use building with 14,600 sf of retail and medical office on the lower two floors and 6,900 sf of residential on the upper floor. The structure was steel framed with composite concrete floors on steel deck and a steel bar joist and metal deck roof. The foundations were drilled piers with concrete grade beams on void form due to highly expansive soils. The main level floor is concrete slab-on-grade. The site soils were highly expansive and recommended over 10 feet of over-excavation. We performed a pricing exercise to assist in determining if over-excavation and spread footings was more cost effective than a deep foundation system for this building. Construction started in the spring of 2019 and was completed in the spring of 2020. The project delivery method was CM/GC with White Construction as the General Contractor providing cost and schedule input and making final design decisions based on their project budget.
The project consisted of designing a new fire station building derived from a prototype developed by HB&A for the City of Aurora. The building is approximately 12,900 sf with offices, day room, kitchen, fitness room, storage, training, and apparatus bays on the first floor and fire fighter dorm area on the second floor. The on-site soils were found to be highly expansive and required deep foundations. The foundations are cast-in-place concrete drilled piers supporting concrete grade beams on void form. The building structure is a combination of steel roof deck supported by custom steel trusses and CMU exterior walls at the apparatus bays. The remainder of the building is steel bar joists supporting concrete-on-steel deck floors with light gauge stud bearing walls. The second-floor roof is gabled wood trusses with plywood sheathing. The building lateral resistance is provided by exterior and interior CMU walls. Construction began in spring 2017 and was completed in the spring/summer of 2018. The project was a standard Design-Bid-Build delivery method. This design team also completed Fire Stations 5 and 16 for the City of Aurora in the last 4 years.
Castle Rock Town Hall Addition
The project consisted of adding a three-story addition to the existing 2-story 22,000 sf town hall. The addition was approximately 14,100 sf with a plan check counter, offices, and conference rooms. A three-story glass atrium connects the two buildings with a glass floor in the 2nd floor hallway. The foundations are cast-in-place concrete spread footing on 3 feet of compacted structural fill. The building structure is a steel frame with steel bar joists supporting concrete-on-steel deck floors and a steel deck roof. The building lateral resistance is provided by stair and elevator reinforced CMU cores and CMU shear walls. Construction began in winter 2016 and was completed in the fall of 2017. The project was a standard Design-Bid-Build delivery method.
Castle Rock Water Administration Building
The project consisted of designing a new single-story administration building. The building is to be approximately 13,300 sf with offices, conference rooms and customer services areas divided from a large meeting room area by a central high-volume atrium/clerestory. The foundations are cast-in-place concrete spread footings on 1 foot of compacted structural fill. The building structure is a steel frame with steel bar joists supporting a steel deck roof. The building lateral resistance is provided by exterior wood sheathed shear walls. Construction is to begin in summer 2020 and be completed in the spring/summer of 2021. The project is a standard Design-Bid-Build delivery method.
