St. Francis Medical Center
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-Build
Meadows at Castle Rock, Town Center Three
This project is a three-story,
mixed-use building with 14,600 square feet of retail and medical office on the
lower two floors and 6,900 square feet 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.
Rock Town Hall Addition
he project consisted of adding a three-story addition to the
existing 2-story 22,000 square foot (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 shearwalls. Construction began in
winter 2016 and was completed in the fall of 2017. The project was a standard Design-Bid-Build
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 shearwalls.
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.
