Brizzolara Student Housing Project (SENIOR PROJECT) January 2015-June2015

Project Type: Educational/ Reinforced Concrete Design Client: Cal Poly Applicable Codes: ACI 318-11 ASCE 7-10

Rancho Grande Park Improvement Engineering Cost Estimate (EDUCATIONAL) April 2015-June 2015

Project Type: Educational/ Cost Estimation Client: Cal Poly: Dr. Korman (Class CE 371) Applicable Codes: N/a

Students who intended graduate from the California Polytechnic State University, San Luis Obispo during the 2015 or 2016 academic years were required to complete a senior capstone project. Groups were assigned as were positions by the Civil Engineering Department. Presented to us was a proposal to house up to 1500 continuing students on the H-12 and H-16 parking lots on the campus. Our group was able to design a floor plan of 5 apartment buildings, a reinforced concrete parking garage for up to 1600 students and staff, a new reinforced concrete bridge, a new road alignment, and the utility lines necessary to run such a community. As a construction lead, I was able to create multiple cost estimates (including one for the bridge and an 80% preliminary design estimate) and a preliminary construction phasing plan. I also made design recommendations and checks for the structural components. I also performed the seismic analysis of the parking garage.

Students of Dr. Korman’s Construction Management Class were required to create an engineer’s estimate of the Rancho Grande Park improvements in Paso Robles, Ca. Using a the drawings provided, quantity estimates of the construction materials; such as concrete and asphalt, were obtained in order to justify the labor crews and the production times of the improvement. Our team was able to estimate that the park improvements would cost about $2.1 million including any soft costs which were also estimated by our crew. The total project time was estimated to be about 6 months according to assumed production time from labor crews.

Tilt-Up Reinforced Concrete Warehouse (EDUCATIONAL) January 2015-April 2015

Project Type: Educational/ Reinforce Concrete Design Client: Cal Poly: Dr. Devaney (Class CE 455) Applicable Codes: ACI 318-11 ASCE 7-10

Moment Resisting Steel Frame Office Building (EDUCATIONAL) January 2015-April 2015

Project Type: Educational/ Reinforce Concrete Design Client: Cal Poly: Dr. Devaney (Class CE 455) Applicable Codes: AISC: Steel Manual 14th Edition ASCE 7-10

Students of Dr. Devaney’s Structural Design Class designed a new reinforce concrete tilt-up warehouse located in Paso Robles, CA. Our crew was able to design the warehouse with 3 walls with no openings and 1 wall with large openings in order to provide loading areas for trucks up to the size of the average American semi-truck. The 3 solid walls are designed according to ACI 318-11 “alternative Design of Slender Walls.” Engineered GLULAMs and I-Purlins were integrated into the beams and girder design.

Students of Dr. Devaney’s Structural Design Class designed a moment resisting steel frame for a four storied office building located in Paso Robles, CA. All structural steel elements were designed based from loading capacities of the AISC: Steel Manual (14ed.) while the panelized roofing was designed from a prefabricated catalog. The loading demand was estimated using moment distribution and portal frame method on all wall lines. An opening on the 2nd floor (the celling of the ground level) was added for architectural design and was accounted for in the ridged diaphragm design.

Arbor Ridge Housing Project: Timber Design (EDUCATIONAL) September 2014-Decemeber 2014

Project Type: Educational/ Timber Design Client: Cal Poly: Dr. Chadwell (Class CE 454) Applicable Codes: American Wood Council: NDS 2012 ASCE 7-10

Evaluating Conservatism within Building Codes According to Lateral Story Drift Due to Seismic Activity (EDUCATIONAL) September 2014-Decemeber 2014

Project Type: Educational/ Risk Assessment Client: Cal Poly: Dr. Moss (Class CE 488) Applicable Codes: ASCE 7-10

Students of Dr. Chadwell’s Timber Design class designed a new housing unit based on architectural plans from the Arbor Ridge Housing Project located in Paso Robles, CA. The National Design Specifications (NDS) by the American Wood Council aided in designed by providing loading capacities of wood and nails and methodologies in order to account for factors such temperature and air/water saturation. Our crew was able to design the entire horizontal and vertical structural elements using Douglas Fir-Larch #2 (DF-L #2) lumbers or engineered GLULAMs with large window openings on the main level for the valley view using Force Transfer Around Openings (FTAO) methodologies. Wood connections were designed using the Simpson Wood Connections Catalog.

Matthew Hoang and I investigated the rick associated with the lateral story drift and maximum story height according to provisions in ASC 7-10. Together, we were able to obtain the acceleration time histories of 20 actual large earthquakes from the PEER Seismic Database while creating a simple wire-frame structure in SAP200. Maximum story drift was determined using the assumed height of the structure and provisions from ASCE 7-10. After the model was created, the structure went through earthquake simulations using the previously obtained acceleration time histories. Using the results from SAP2000, a first order second moment risk analysis was used due to the uncertainty in both demand and capacity. We were able to find that if designing the story height to the code standards, the story drift would only exceed the max <1% of the times

San Luis Obispo Target Settlement Project (EDUCATIONAL) January 2014-March 2014

Project Type: Educational/ Shallow Foundation Client: Cal Poly: Dr. Moss (Class CE 481) Applicable Codes: N/a

Reinforced Concrete Floor System Design (EDUCATIONAL) September 2013-Decemeber 2013

Project Type: Educational/ Reinforced Concrete Design Client: Cal Poly: Dr. Kachlakev (Class CE 355) Applicable Codes: ACI 318-11 ASCE 7-10

Students of Dr. Moss’s Shallow Foundation Design class were asked to design a mitigation technique to account for the soft alluvial soils under the future Target supermarket. The selected mitigation technique was to preload the project site and install wick drains in order to “pre-settle” the soils. We were able to determine the amount of settlement due to the loading by analyzing the “e-log-P” curves and the wick drain spacing for a 90% consolidation in 3 months.

Students of Dr. Kachlakev Reinforce Concrete Design class designed the top level of a reinforced concrete structure. Designs of the structural elements were aided by the methodologies of chapters 7, 8, 9, 10, and 11 of the ACI 318-11. An estimated dead, live, and architectural façade loading was provided and factored accordingly. Microsoft Excel spreadsheets were used to create a design “program” to ease the iteration process of design. Our crew was able to completely the design a reinforced concrete vertical support system of the top level of the structure; including the slab, girders (as T-beams), and beams.
