Washington International Airport | Expansion of International Arrivals Building |
Setty provided an MEP Report outlining potential impacts of the revised phasing for cost estimating purposes, for the Project Definition Document (PDD) for the expansion of the International Arrivals Building.
New construction included:
Setty provided MEP and Sustainable Modeling services in the development of the MWAA green roof study, encompassing three buildings.
Scope of services included:
FAA-DTW Airport Traffic Control Tower | Upgrade HVAC & Mechanical Systems |
Setty provided technical resources in conjunction with project requirements to upgrade HVAC and mechanical systems associated with the Mold Assessment and Remediation Project, at the Air Traffic Control Tower and base building at DTW Airport.
Scope of services:
Concourse C-D was built in 1985, conceived as a temporary facility. The airport growth led to construction of permanent midfield Concourses A and B while C-D began to show its age. The purpose of the rehabilitation project was to extend the useful life of the C and D Concourses until a permanent replacement could be built nearby.
SETTY provided a facility condition assessment of Concourse C/D and a multiyear expenditure forecast in response to the conditions of the building and systems that are detailed by the assessment. The assessment identified visually apparent deficiencies in the building and systems. It also included site evaluations, interviews with management and maintenance personnel, and reviewed available maintenance records and design and construction documents.
Built in 1941, the historic Terminal A continue to serve passengers and provide airline gates, ticket counters, and concessions. The design, reminiscent of nearby Mount Vernon, represented a unique attempt to create a “modern” structure while still integrating architectural references to the Colonial and Neoclassical style.
SETTY team provided a study report for emergency generator upgrade at terminal A. It was recommended that the new generator be sized not only to meet the present and near future emergency power requirements of the Terminal A, but also to provide adequate (approximately 25%) spare capacity to permit future growth. Setty provided recommendation to provide a new generator large enough to meet the scope requirements and all related items, such as ATS, 277/480 volt panels, step down transformers, low voltage 120/208 volt panels and associated conduits and wiring.
SCOPE OF WORK INCLUDES:
The National Airport site is rich in historical significance dating back to colonial days. Washington National Airport was renamed in 1998 to honor former U.S. President Ronald Reagan. The Metropolitan Washington Airports Authority (MWAA) operates the airport with close oversight by the federal government due to its proximity to the national capital.
SETTY staff interviewed the Central Plant staff and terminal building staff where chilled water is received from the Central Plant, and reviewed the original design plans of the Central Plant. This fact finding was used to determine how the chilled water thermal storage system is operated, what operational issues exist with the current operation, and past maintenance work (and thus maintenance issues that once existed) completed for the chilled water system. The existing thermal storage tank stores 38°F chilled water which is generated overnight by operating five 900 ton chillers during the twilight hours. The thermal storage system is used to avoid peak electrical demand charges that would be experienced during daytime hours if the 38°F chilled water was generated during the daytime. The capacity of the chilled water thermal storage tank is 2.2 million gallons, which results in a cooling capacity of 34,356 MBH. During the daytime, one 900 ton chiller and the thermal storage tank are available to provide cooling. Thus, the total cooling capacity of the chiller plant under the current operation is 45,156 MBH.
Denver International Airport often referred to as DIA, is an airport in Denver, Colorado. At 54 square miles, it is the largest airport in the United States by total area. Runway 16R/34L is the longest public use runway in the United States. As of 2014 the airport is the 15th busiest airport in the world by passenger traffic and sixth busiest in the world by aircraft movements.
SETTY was contracted to provide a survey and assessment of failing manholes, provide recommendations and options for remediation / replacement and engineering design for construction project of four manholes at the Denver International Airport. The report describes the field assessment, options and preliminary engineering based on survey findings, existing data and testing.
The field assessment and analysis of previous existing data and reports revealed serious deteriorating conditions, cracking and leaking, flooding and corroding occurring for some time in all four manholes. The situation observed was hazardous to the cabling integrity and the cabling supports. Setty provided services for underground vaults and manholes construction project that was designed to rebuild the manholes without interruption to the communication cables or the air traffic activities. The four rebuild vaults and manholes are now waterproof, safe, maintenance free and can accommodate additional cable services.
Washington Dulles International Airport (IAD) is located on 12,000 acres as a major hub for domestic and international air travel.
SETTY provided the South Finger - ATCT Tower Facilities Assessment & Long-Term Rehabilitation Study for Washington Dulles International Airport. For the renovation and conditioning assessment project, typically the project scope and the project requirements get fully analyzed. Then the existing condition drawings get reviewed, when such drawings are available. After reviewing the drawings, the design team consisting of one senior engineer from each affected discipline visits the project site. All the existing site conditions and the data associated with the project area get surveyed and documented.
For this project, the electrical engineers sorted the existing and new systems into four main categories: (1) existing equipment and related systems that need to be entirely removed; (2) existing equipment and related systems that will be removed and relocated; (3) any new panels and equipment needed and how best to feed them; and (4) existing service equipment that have the spare capacity to support additional loads/panels. The main object of the electrical assessment is to find the best design solution, so that the contractor can perform his work, without causing extensive power interruption or affecting the normal building operation.
The site assessment report prepared was based on the project scope (program) and the existing site conditions. The assessment report outlines the condition of the existing equipment in general and the power distribution systems, any code and safety violations, remaining life expectancy of the existing equipment and main systems, and the budgetary cost for all the recommended upgrades. Our assessment report also includes recommendations so that the owners can promptly address any code and/or safety violations or any critical systems that might be in failing condition. Our recommendations for repair or replacement are typically based on the means and methods, which will cause least inconvenience to the building occupants and operation, and will be least expensive. Since this project site has a 24/7 operation, maintaining power, lights and normal operation are considered the most critical factors in any assessment analysis.
The public airport in Dulles, Virginia is the busiest airport in the Washington metropolitan area, and second busiest airport in the larger Baltimore–Washington metropolitan area. The airport is named after John Foster Dulles, the 52nd Secretary of State and served under President Dwight D. Eisenhower.
SETTY was contracted to provide a quick turnaround of demolition and construction drawings, specifications and cost estimate, in accordance with MWAA standards, for air distribution system replacement for 6,000 sf second floor administrative area Building 8, the Telephone / Weather Building at Washington Dulles International. Temporary air-conditioning was provided due to the required system shutdown. Project consisted of:
