[Analysis 1 | Support of Excavation Redesign]

 

The project support of excavation was initially designed as a soldier pile and lagging system.  Through value engineering activities, the design was changed to a modular block wall system.  This analysis will research both of those systems as well as an alternative system, sheet piles.  They will be assessed based on the time each system takes to install and the overall cost of the system. 

 

[Analysis 2 | Underground Parking Garage Redesign]

 

The underground parking garage structure on this project is precast concrete.  The change from a precast concrete structure to a cast-in-place concrete structure can potentially reduce the overall schedule.  The analysis will include a total duration comparison (including lead times) as well as a cost comparison.    Part of the cost analysis will have to include temporary heating, due to the erection taking place during winter months.

 

[Analysis 3 | Short Interval Production Scheduling for Interior Office Space]

 

The interior construction of the office space is very repetitious and includes large open spaces.  These conditions are very suitable for the implementation of short interval production scheduling (SIPS).  Through this analysis, a SIPS will be created for the interior construction sequence.  Overall, the implementation of SIPS will decrease the duration while improving the efficiency and learning of the trades. 

 

[Analysis 4 | Industry Research: Supply Chain Management]

 

Supply chain management during construction plays a vital part in maintaining the project schedule.  The Celgene Building L project encountered issues related to supply chain management and material tracking.  The research that will be conducted and analyzed will focus around the manufacturing process and material tracking of the specific metal panel utilized on the project, and ways to improve it. 

 

[Structural Breadth | Analysis 1]

 

The first analysis focuses on the evaluation of three support of excavation systems.  The project support of excavation was initially designed as a soldier pile and lagging system.  Through value engineering activities, the design was changed to a modular block wall system.  This analysis will research both of those systems as well as an alternative system, sheet piles.  They will be assessed based on the time each system takes to install and the overall cost of the system.  A decision will be made as to which system provides the best value to the project based on the above criteria. 

 

To better understand the duration and cost of the systems, a structural analysis will be completed for the soldier pile and lagging system in addition to the sheet pile system.  The schedule and cost information has been made available for the implemented modular block wall system, so no additional analysis is needed.  To accomplish the structural breadth, one section of the support of excavation system will be calculated and then extrapolated to the entire area.  This high level design is the most accurate way to obtain schedule durations and costs. 

 

Deliverables

o   Calculations for sizing and quantities of the support of excavation systems

o   Accurate schedule and cost information

 

[Mechanical Breadth | Analysis 2]   

 

The second analysis focuses on evaluating the change of the underground parking garage structure from precast concrete to cast-in-place concrete.  Maintaining the current time frame for the underground parking structure will require the use of a temporary heating system, due to the erection taking place during winter months.  This heating system will be implemented with a temporary wall structure to enclose the floor being currently erected.  As the structure moves higher, the temporary wall and heating system will do so as well.  This study will include heating load calculations dependent on the thermal resistance of the temporary wall, system selection, and a basic distribution design.

 

Deliverables

o   Type of temporary heating system

o   Size of temporary heating system

o   Accurate schedule and cost information
