Architecture

The Temecula Medical Center is designed as a trademark medical facility for the city of Temecula and the surrounding region. It has 6 stories and is approximately 107' tall with it's most predominant feature being the circular tower on the south side. The south tower serves as the main vocal point with large banded windows as well as 4 distinct column points. The exterior facade is made up of mostly portland cement plaster but also features porcelain wall tile (lining parts of the ground level exterior), and pre-finished metal panels (on lower floors).

The roof system of the medical center consists of pre-formed, pre-finished sheet metal coping caps to match the plaster as well as sloped rust colored roof tile.

Being located in California, the Temecula Medical Center maintains many architectural motifs originating on the west coast. This style is brought out in the numerous windows on the facade, as well as the rust colored roof.

Structural Overview

Lateral System
The lateral forces are resisted predominantly by concrete shear walls placed throughout the plan. The elevator shafts serve as the main component of the lateral resistance system. Shear walls are typically 27’-9” long, and 2’ thick with varying reinforcement sizing and spacing. Each wall is built with a minimum 28-day compressive strength of 7000 psi. Specifically labeled walls have a compressive strength of 9000 psi. The shear walls are anchored to the supporting soil by footings, typically 6’ deep and reinforced with #9 at 9” o.c. See Chart and Figure below for additional details on the existing system. The bold shapes represent the shear walls placed throughout the floor plan.

Concrete Strengths
F’c (psi)                      Conc. Type    Max. Agg. Size
Typical Shear Walls                  7000 (56-day)              N.W.C .           3/8”
Shear Walls (where noted)        9000 (90-day)              N.W.C.            3/8”

Floor System
The floor system of the first floor consists of a 5” slab-on-grade while the remaining floors of the Drug and Therapy Center (D&T) are supported by various sized precast, prestressed double-tees. The 6-story bed tower consists of two-way, 10” reinforced concrete flat slabs. Slab reinforcement ranges from #4 bars to #6 bars, spaced from 6” to 9” on center.

Topping slabs of the double tees in the D&T consists of 6” normal weight concrete, typically reinforced with #4 at 9” o.c. Typical spans between tee’s is 6’-0 but vary on location. Two-way flat slab reinforcement sizes for the 6-story bed tower vary but are placed equally across designed column and middle strips. A typical floor layout is shown below.

Roof System
The lower roof over the 6-story bed tower is composite slab with 4 ½” normal weight concrete over 2”, 16 gage composite metal deck (galvanized), reinforced with #3 at 9” o.c. each way. Supporting the 1 ½”, 20 gage metal deck on the high roof are rolled steel W-shapes, typically W10x17, 33, or 45. The roof system over the 2-story D&T is very similar and consists of a 1 ½”, 20 gage metal deck held up by rolled steel W-shapes, varying in size from W8 to W18.

Foundation
The foundation is a combination of spread footings and drilled piers with concrete pier caps. The spread footings vary in size from 5’x5’ to 18’x18’, depending on location, and are labeled F5-F18 accordingly. The reinforcement for these footings goes from 16 #5 each way in the F5 to 18 #9 each way in the F18.

Foundations for the shear walls feature footings anchored to the supporting soil by drilled piers, typically being 42” in diameter. Each pier is spirally reinforced, varying in size while the pier caps are typically reinforced with #9 - #11 at 9” o.c.

Columns
Vertical supports for the first level consist of 26” x 26” cast-in-place columns as well as 20” x 20” precast columns, however the upper floors (2-6) have only the 26” x 26” cast-in-place columns.  A typical bay size is 54’ x 27’, although they vary depending on location and demand.

The cast-in-place columns typically run from spread footing through each floor while being reinforced with 12 #9’s vertically and #4 at 6” o.c. horizontally. Pre-cast columns are reinforced with 4 #9’s vertically and #4 at 5” o.c. horizontally. The compressive strength for the C.I.P. columns is 5000 psi and the strength of the PL columns is 6000 psi.
