User Note:

While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work-in-progress for this thesis project. Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Natalie Bryner. Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design.





























Techanical Assigment One

Within this technical report, one can find information pertaining to the renovation of Constitution Center which is located in Washington, DC. There is information about the project schedule and how James G. Davis Construction Corporation (DAVIS) planned to start construction in July 2007 and turn the building over in four quadrants starting July 2009 and finishing November 2009. Additionally, one can find information about the building systems that are being installed. Next, there is an evaluation of the cost of the project, followed by a site plan containing information about the existing conditions. Washington, DC’s local conditions are outlined, along with information about the client, David Nassif Associations. Finally the project delivery systems and the staffing plan of DAVIS are found at the end of the report.


Techanical Assignment Two

Technical Assignment 2 deals with the cost and methods of construction on Constitution
Center, which is a renovation of the Department of Transportation (DOT) building found
between 6th and 7th Street and D and E Street in SW DC.

Information about the detailed project schedule is included and how the project was sequenced for the interior and exterior façade. Additionally, three site plans were developed for Constitution Center. They are for the demolition, superstructure and finishes phases of construction. One unique feature about these plans are that most of the information does not
change from one phase to the next since DAVIS is utilizing the parking garage for storage and the offices are found on the second and third floors of the building.

A detailed system estimate is also included in this document. The curtain wall of Constitution Center was examined and an estimate was calculated. This estimate is within 2.2% of the actual estimate provided by DAVIS. Also, a general conditions estimate was calculated and it was determined that the project staff cost are 76% of the total general conditions. Furthermore, the general conditions only make up about 3% of the overall $244,700,033 project cost.

Finally, this report is concluded with an overview of the PACE Roundtables which occurred on Thursday, October 16, 2008. In this particular section, one can find information about the mentoring program that is planned to be established in the Architectural Engineering Department. Additionally, information about the “LEED Evolution” seminar is evaluated and surprises about this session are noted. To finish, an outline of the two panel discussions are included.

Overall, this technical assignment will give an overview of the cost and methods of construction in order to build a 1.5 million square foot office building that has a total cost of


Techanical Assignment Three

Technical Assignment three consists of information pertaining to the alternative methods and the analysis of these methods. In the first section, one can find a study of the constructability challenges that were faced on Constitution Center. The items that were examined were the weight of the boilers, the metro station entrance, and the density of the MEP installation. The weight of the boilers posed a problem since none of the four tower cranes on the site could perform the lift. The metro station entrance was a challenge because the Washington Metropolitan Area Transit Authority (WMATA) would not permit the entrance to be closed during the entire construction. The final constructability challenge that was studied was the density of the MEP installation and how DAVIS redesigned the largest chilled beam system being
installed in the United States.

The second section of this analysis is ondifferent types of schedule acceleration scenarios. It is noted that there are several items apart of the critical path on Constitution Center, such as demolition, curtainwall, permanent power, mechanical systems completion, commissioning by phase, and final inspections. Additionally, one can find information on the biggest risks to the completion date, which include the amount of the liquidated damages. Finally, two areas of potential acceleration are discussed, along with the costs and techniques of both having multiple crews working and how DAVIS is accelerating the permanent power transition.

Value Engineering topics are outlined in the third section of this evaluation. One can find information on actual topics that were implemented on Constitution Center, along with how they correlate with the goals of the owner. Also, several value engineering ideas are discussed that were considered but not implemented.
In the fourth section of this analysis, one can find several problematic features that could be furthered outlined through a detailed analysis of technical building systems and construction methods. The features that are outlined include the density of the MEP installation, curtainwall, site layout, waffle slab renovation, CCIP, and pedestrian safety.

In the final section of this report, four construction management analysis activities are summarized, along with how it will be completed, and the research that may be necessary. The four sections that are discussed include the chilled beam system, the façade, pedestrian safety, and the structural integrity of the parking garage waffle slabs.
