2 Sarah Lippai Construction Management JetBlue Training Facility Orlando International Airport Primary Faculty Consultant: Dr. Horman Due Date: Monday, November 15 th, 2004 Executive Summary Through this technical assignment, I developed a better understanding of the temporary construction needed, the exterior closure system, and the costs related with the project. This was achieved through the Site Layout Planning, Temporary Utilities, Detailed Systems Estimate, General Conditions Estimate. Research methods were discussed for developing methods of analysis on the building enclosure in the Research and Analysis Methods. Site Layout Planning Site Plans for excavation, superstructure, and finish phases are included in this section. A description of the key features is discussed. Temporary Utilities General temporary utility requirements are discussed along with the requirements for concrete, fireproofing, and interior finishes installation. Requirements for the safety and health of employees are discussed for the Florida construction environment. Detailed Systems Estimate A detailed estimate of the exterior closure was prepared following the Assemblies Estimate in Technical Assignment #2. Quantities were taken off from the plans and cost data was obtained from R.S. Means. Spreadsheets with detailed quantities are attached. General Conditions Estimate An estimate of the General Conditions for the project was developed using project cost data and R.S. Means. These are general costs incurred by Suitt Construction during the project. Research and Analysis Methods A problem statement that identifies the construction issue that I will research is included. The target audience and benefactors will be addressed. Methods of research will be explained along with a draft of the interview questions

3 Sarah Lippai Construction Management JetBlue Training Facility Orlando International Airport Primary Faculty Consultant: Dr. Horman Due Date: Monday, November 15 th, 2004 Site Layout Planning Site Trailers were located far enough away from the site as to not interfere with daily activities, but with an available view of the entire site. The owner, JetBlue Airways, and his representatives, Tishman Construction, were located in a trailer, while the general contractor, Suitt Construction, and the MEP subcontractors were located closer to the site. Temporary parking was located for staff and visitors adjacent to the owner trailer and laborer parking was located adjacent to the general contractor trailer. Access to the site was via the entrance at the end of Hangar Road and continued through the site to eliminate turnaround areas. Excavation Phase With the Florida location and relatively level ground, deep excavation was not necessary. Support for excavation and large excavation stockpiles were not necessary because of this lack of excavation. Small excavation equipment will be used around the site. JetBlue Airways requested that Suitt Construction keep Hangar Blvd clean of mud and debris. Storage and materials staging areas were set up on the north side of the site, close to the construction trailers and parking areas. Superstructure With the concrete being poured and the structural steel being erected, a third entrance/exit to the site was opened for easy movement around the site. Staging areas were laid out over the site to allow movement of the mobile crane. Dumpster locations were moved to accommodate the laborers better. Finishes Areas were allowed within the building for the staging of finish materials near their locations of installation. Metal for inside the simulator bays was laid out within the simulator areas. Final locations for these materials have not been decided since the building is still weeks away from these stages. Excavation and beginning superstructure phases were laid out based on experience and pictures from the site during the summer. Later superstructure and finish plans were based on conversations with the superintendent - 3 -

7 Sarah Lippai Construction Management JetBlue Training Facility Orlando International Airport Primary Faculty Consultant: Dr. Horman Due Date: Monday, November 15 th, 2004 Temporary Utilities Under each section of the specification, it lists the criteria required for delivery, handling, and storage of the superstructure materials. Temporary Utilities are described in the General Requirements and Supplementary Conditions of the RFP documents. All costs for furnishing the temporary facilities at the site are the responsibility of Suitt Construction. New facilities must not be used as a temporary facility for construction purposes. With the Florida location, temporary heat is not an issue, but cooling can be a major issue for the workers. For the safety of the workers, temporary shade structures are erected to provide protection for them during breaks and lunch. Temporary water will be brought from the water line branches across Hangar Blvd. Temporary light and power are drawn from the main service that will provide power to the Training Facility. Temporary lighting shall be provided for all public areas during construction. All motors and equipment must conform to temporary power characteristics and be grounded, meeting all codes and safety regulations. Temporary ventilation is needed throughout the construction for the comfort and protection of the workers and the drying and curing of materials. This tied in with material management will be demonstrated for various materials for the superstructure. Cast-in-Place concrete is used throughout the building and the site, and was poured during the hottest time of the year in Florida. Cast-in-place was used for foundations, slab on grade, and the simulator slabs. The quality of concrete is especially important in this area, since it will anchor the active simulators providing support to prevent overturning. When the air temperature is between degrees Fahrenheit, the mixing and delivery time needs to be reduced from 1-1/2 hours to 75 minutes, and when the temperature is above 90 degrees Fahrenheit it must be cut down to 60 minutes. The temperature of the concrete must be below 90 degrees Fahrenheit at the time of placement requiring that chilled water be added in some instances

8 Sarah Lippai Construction Management JetBlue Training Facility Orlando International Airport Primary Faculty Consultant: Dr. Horman Due Date: Monday, November 15 th, 2004 During the curing process, the contractor is responsible for keeping the concrete moist and free from rain and running water. A moisture curing retaining cover can be placed on the concrete to keep it hydrated. During the numerous rainstorms in Florida, the concrete must be covered with plastic covers to prevent over-hydration. When temperatures exceed 80 degrees Fahrenheit, one test hourly must be done for each composite sample. Sprayed Fire-Resistive Materials must be stored in a dry area without any damages. The area of application must be well ventilated prior to and after application of the sprayed fire-resistive material, using forced-air circulation until the fire-resistive materials dries thoroughly. Temporary enclosure of the area to confine the spraying operations and to protect the environment must be established. The temporary enclosures should also prevent deterioration of the fire-resistive material due to weather, humidity, and ventilation. Adequate protection shall be provided for all interior finish materials, like wood work, doors, drywall, and floor tile. Efforts must be made to keep these materials free from rain, humidity, and overexposure to the sun. Since the building should be mostly enclosed by this stage, the main concern is standing water that may develop within the structure

9 Sarah Lippai Construction Management JetBlue Training Facility Orlando International Airport Primary Faculty Consultant: Dr. Horman Due Date: Monday, November 15 th, 2004 Detailed Estimate: Exterior Closure To further investigate the cost of the exterior skin of the JetBlue Training Facility, I performed the detailed estimate of the precast panels, metal panels, doors, curtain wall and storefront, and the structural system that holds it in place. A quantity take off was performed, and all unit costs were obtained through R.S. Means. A Summary of the estimate is on the following page, and the detailed breakdown is available in Appendix A. Total Exterior Closure Cost: $1,792,825 Assumptions: Modification of an additional 50% in Material Unit Cost for Concrete Precast Panels was made since R.S. Means data was only for 4 thick instead of 8 Unit costs for Lightweight angle framing was obtained from the equivalent of 0.4 lbs is equivalent to one square foot from the assemblies estimate Modification factors are estimates from national averages - 9 -

13 Sarah Lippai Construction Management JetBlue Training Facility Orlando International Airport Primary Faculty Consultant: Dr. Horman Due Date: Monday, November 15 th, 2004 Element of Research Research and Analysis Methods Concrete structural systems are predominantly used in the Florida area. Concrete tilt-up panels are a cost effective and widely used system in the central Florida area. However, the JetBlue Training Facility uses an aluminum composite and steel corrugated panel system with precast concrete panel system. After talking with Paul Wood, the Project Manager for JetBlue Airways, this summer, he mentioned about how the use of tilt-up concrete panels could have been another option for the construction of the facility. I would like to consider the cost comparison between these two systems. Having Rubin and Rotman Architects, the architect who performed the base design for the facility, from Canada may have affected the design of the structural system. They were chosen based on their knowledge of designing Simulator facilities, not on their familiarity with the Orlando International Airport area. Through my research, I would like to get a better understanding of the reasons for choosing the metal panel and precast panel system. With this research, I would like to give a better understanding to JetBlue staff and introduce another option for future construction with the JetBlue Facility team. Research Steps As I research this topic, my first contact will be Paul Wood. He can provide me with some of the reasons behind the system chosen, if it was a JetBlue or Rubin & Rotman decision. I will also consult with Tom Reilly, Randy Winger, and Bryan Pickens at Suitt Construction Company to learn more about the two systems and the differences between them. Along with interviews with the professionals in the industry, I plan on researching concrete and engineering journals to find more information about the benefits of these systems

14 Sarah Lippai Construction Management JetBlue Training Facility Orlando International Airport Primary Faculty Consultant: Dr. Horman Due Date: Monday, November 15 th, 2004 In Technical Assignment #2, I performed an Assemblies estimate using R.S. Means on the exterior closure of the building. Also in Technical Assignment #3, I performed a detailed estimate of the same system. Hopefully between these two estimates, I can obtain a cost comparison to the alternative concrete tilt-up panel system. Interview Questions 1. In the original design phases, were concrete tilt-up panels an option? If so, why were they not chosen? 2. Are concrete tilt-up panels usually the method of construction for this type of building in the area? 3. What are the advantages of using metal panels in conjunction with concrete precast panels for the exterior closure? 4. With the cement shortage that occurred this past summer, was it a better choice to have designed with metal panels for part of the construction? 5. Did the northern influence of Rubin & Rotman affect the design of the structure? 6. Did Rubin & Rotman s experience building Simulator Facilities, influence the decision to construct using metal panels and precast? 7. Do you think it is detrimental to the project having original design architects from outside the Florida area? 8. In the future, should more of the original design been open to the Design/Builder? 9. Considering productivity and equipment, does one system fit the project schedule better? 10. Considering the needs of the project, is one system more appropriate? 11. Was cost a consideration when choosing metal and concrete precast panels over concrete tilt-up panels? 12. If the facility was being built again, would you have constructed it differently in regards to the exterior skin?
