THESIS PROPOSAL

 

Overview

Senior Thesis Final Proposal is intended to discuss the four analyses that will be performed for the final thesis report on the Saint Vincent Health Ceter Addition. Each topic is centered on the central theme of improving efficiency in the construction industry: project schedule efficiency, BIM & prefabrication efficiency, site safety & efficiency and facade efficiency.

REPOST ORIGINAL FINAL PROPOSAL

 

ANALYSIS #1: Schedule Reduction from Re-sequencing Construction Phases

The proposed sequence has multiple phases with demolition work overlapping new construction activities throughout the entire project schedule. Phased occupancies are planned for the Emergency entrance, connecting corridor and In-Fill Addition and the Existing Hospital to accommodate Saint Vincent’s requirements. This scenario creates potential problems with trade coordination, contractor delays. There will be several contractors switching between renovation, demolishing and new construction work which will make coordination and schedule understanding extremely difficult. The goal of this analysis is to perform an in-depth re-structuring of the project schedule to reduce schedule length by working on phase 1 and 2 unrelated tasks simultaneously. Creating a 4D model to show sequencing and phasing will be useful for this analysis.

 

ANALYSIS #2: Improving Site Coordination and Safety


Safety is one of the biggest concerns on any job.  Since this project is located on an active hospital complex, several problems exist with ensuring the safety of the patients/employees while maintaining a productive site. Several measures must be in place to separate hospital and construction activities without sacrificing hospital operations. The fact that the two adjacent structures that the addition will be attached to will be occupied during construction presents a challenge to public safety. The goal of this analysis is to create a 4D site model to limit and reduce site congestion and improve safety for workers and pedestrians. The site model will show work flow, material laydown areas, delivery entrance and pedestrian entrances and how they will change throughout the project.

 

ANALYSIS #3: Critical Industry Issue: Elimination of Inefficiency through use of BIM and Prefabrication


Hospitals typically have a lot of coordination that is need between the MEP trades. BIM could improve the coordination and reduce the delay time with the MEP work that will be done on this project.  I will look at the costs, schedule, potential results, and the ability of the project team to decide how the MEP coordination process could be conducted more efficiently with the use of BIM. The use of prefabrication should reduce the schedule by decreasing the MEP placement work time.

 

ANALYSIS #4: Improving Efficiency by using on common Façade System


The proposed façade is currently a combination of many different materials including brick, stone, a curtain wall, and metal panels: white and stainless steel. The details for all of these connections are very time consuming and difficult to comprehends. Simplifying the façade to just one system would allow for less details and more consistency allowing the construction to run more smoothly. The materials would need to be researched to see if there are alternatives that have easier connections. The materials also need to have similar properties to perform the same. Precast masonry is also a possibility to decrease construction time and site congestion.  This analysis will be including a portion of the structural breadth by analyzing and designing additional supports and connections.

 

ANALYSIS #5: Develop an Infection Control Risk Assessment (ICRA) Plan


There are many considerations in the design and construction or renovation of the health care facility. The environment must cultivate a safe, caring, healing environment for patients and their loved ones, while also being efficient, functional and safe for staff. Improperly designed and maintained environments pose numerous risks for patients, including hazards from fires, chemical exposures, or contaminated air, water or environmental surfaces.
The goal of this analysis is to develop an ICRA plan for the hospital to keep a safe and clean condition for the patients.  This analysis will include a mechanical breadth by check the mechanical capabilities to make sure the hospital could pressurize the building to prevent dust and health hazards.

 

STRUCTURAL BREADTH: Contributes to Technical Analysis #4


The proposed façade is currently a combination of many different materials including brick, stone, a curtain wall, and metal panels: white and stainless steel. The details for all of these connections are very time consuming and difficult to comprehends. Simplifying the façade to just one system would allow for less details and more consistency allowing the construction to run more smoothly. The materials would need to be researched to see if there are alternatives that have easier connections. The materials also need to have similar properties to perform the same. Precast masonry is also a possibility to decrease construction time and site congestion.  
This analysis will be including a portion of the structural breadth by analyzing and designing additional supports and connections. The current façade is hand-laid masonry, but since the structural is Steel beams and columns and there are problems with site congestion already, precast masonry might be a viable option. A structural analysis will be constructed to size the beam sizes to hold the precast panels.

 

MECHANICAL BREADTH: Contributes to Technical Analysis #5


There are many considerations in the design and construction or renovation of the health care facility. The environment must cultivate a safe, caring, healing environment for patients and their loved ones, while also being efficient, functional and safe for staff. Improperly designed and maintained environments pose numerous risks for patients, including hazards from fires, chemical exposures, or contaminated air, water or environmental surfaces. The goal of this analysis is to develop an ICRA plan for the hospital to keep a safe and clean condition for the patients.  
In the ICRA plan, it calls for the hospital to be positively pressured. My mechanical breadth analysis will be checking the mechanical capabilities of the air handing system to make sure the hospital’s system could make the building be positively pressurize to prevent dust infiltration and health hazards.
