The airport and support facilities are essentially the only structures occupying the plateau resulting in a limited contextual fabric. The site analysis consists of five diagrams that help establish important issues affecting potential design decisions. Diagram - Existing Facilities. The existing facilities diagram is an attempt in a brief manner to establish areas occupied by specific functions. Airport support facilities are those directly utilized by airport operations. These structures and fuel storage facilities are used to store materials and equipment for airport, aircraft, and runway opera­ tions. Airport tenant functions are spaces the airport leases to approximately 90 tenants. The lessees near the terminal are presently occupied by private hangars and Lynch and Cillis Aviation. As airport needs increase, leased functions would undoubtedly be relocated, perhaps to the west end of the airport complex where potential development of private hangars appears most appropriate. Parking is shown in an attempt to indicate the amount of area necessary to accommodate present parking needs for SITE long- and short-term automobile, employee, and car rental. Diagram - Runways and Vehicular Access. Air carrier runway shown in black is the runway utilized by commercial air carriers and general aircraft. The runway is 150 feet wide by 10,500 feet long and is capable of accommodating larger aircraft, i.e., 747's. Basic transport and general utility runways are used exclusively by general aircraft. Taxi is space required for aircraft to maneuver to and from the terminal and hangars, to runways. Aircraft land and takeoff in directions dictated by current weather conditions. Vehicular access to the site is realized from three routes: Highway 318 from the east, Highway 3 from the west, and 27th Street from Interstate 90 south of the city. The point where the three con­ verge has developed into a problem with serious potential and will therefore be considered in the design. Because of the expected increase in airport usage, the entrance issue becomes an important element within the airport design and should be addressed in a manner which will provide a positive solution to meet future demands. 15 Diagram - Noise. Noise is without a doubt an expected issue at airports. This diagram denotes the SITE severity of the problem, though the duration of noise is related to air traffic at specific times of the day. Through proper location of the building a buffer could be generated allowing the possibility of exterior space. Because noise is an inherent characteristic of airports, the building envelope must be given special care, especially in detail to insure appropriate control. 1 fi Diagram - Sun Path and Wind. The site, due to its vertical location and absence of surrounding structures, enjoys ample sunlight. This character­ istic might support large areas of glazing or atrium space within the terminal. The site also is not buffered in any sense from winter storms and wind. Care, therefore, needs to be exerted to provide barriers via walls or plantings to protect passengers as they enter and leave the building envelope. Diagram - Views to Surrounding Landscape. There exist views in two senses at the airport site, though only one, views to surrounding landscapes, is diagrammed. Views in close proximity to the site, particularly toward runways, provide site occupants a very dynamic visual involvement with the airport. The terminal should provide ample visual links toward runways, internally. SITE The site, due to its unique vantage point, provides views to distant landscapes perhaps not experienced from a less elevated location. From the control tower the city and entire valley unfold providing a unique experience. This can provide an excellent opportunity architecturally to provide an elevated observation space from the airport. Views have been described as desirable, neutral, and undesirable. Neutral views are those which, apart from the aircraft activity, represent visual access toward unbroken plains or residential develop­ ment. These views to the north are in no sense negative but assume a secondary position in relation­ ship to views toward the south into the city. legend EXISTING FACILITIES airport support Hi airport tenant parking Y//A legend RUNWAYS & VEHICULAR ACCESS primary access-27th st. secondary access- hwy.3 &318 air carrier basic transport general utility taxi / A ••• \ 27th st. to Interstate 90 legend NOISE ZONE 1-less than 65 dB ZONE 2-65 to75dB ZONE 3-greater than 75dB lltlS wmmm frrrDdTr>ii ii iir>v legend SUN PATH & WIND winter winds 12.4 mph ave. summer winds 9.9 mph ave. legend VIEWS TO SURROUNDING LANDSCAPES desirable 1 1 neutral ImM Due to the elevated and rather obstruction-free location of the site, climatic characteristics might offer valuable information affecting design develop­ ment. "Billings, Montana, at an elevation of 3100-3600 feet above mean sea level, is situated in the border­ line area between the great plains and the Rocky Mountains and has a climate which takes on some of the characteristics of both regions. Its climate may be classified as semiarid, but with irrigation and the favorable distribution of the precipitation during the spring and autumn months, it is possible to raise a variety of crops in the area." 1 P Diagram - Precipitation and Snowfall. Billings receives on the average a little more than 14 inches of precipitation a year with the majority of it falling in the spring and fall months. Although the amount of precipitation is low, there does exist the possibility of substantial snowfall in winter months. The winters are generally interrupted with mild periods resulting in thawing of snow accumulations, but adequate space should be considered for snow removal from parking and pedestrian paths. 19 Diagram - Temperature and Humidity. * The temperature in Billings is uncommonly mild for the region, especially in winter, as it frequently enjoys a CLIMATE "drainage wind moving down the Yellowstone Valley which transports warmer air of Pacific origin to the 2 0 area." Summer temperatures are comfortably warm with mild nighttime temperatures. Humidity does not pose as a detrimental condition of the site but rather helps maintain a comfortable environment, particularly during summer and early fall. In part due to tem­ perature^ and site orientation, interior green space might be explored in an attempt to provide an inviting environment during winter months. Diagram - Clear, Partly Cloudy, and Cloudy 21 Pays. This diagram reveals that the expected conditions for Billings skies is partly cloudy, although generally these clouds are not low lying. In the summer months Billings enjoys azure blue skies which provide a dynamic backdrop for a strong visual image architecturally displayed in the control tower. Sky conditions also give impetus to interior green space, though insulating thermal loss during winter months would be necessary.

Because airports tend to exhibit anonymous space, there has been an attempt to first define the space and establish a quality desired to provide direction as the design process continues. Included within the program are conceptual sketches which provide initial direction for the airport's internal character. These sketches were an exercise to aid me in graphically expressing verbal intentions for a space; they are not intended to depict the final architectural form, but rather the mood or quality of space. There does exist within the program assumptions which were made due to the extensive research neces­ sary to address needs for specific airports. For instance, airline operation space was treated in a generic sense, and in actuality considerable time would need to be spent with each airline establishing an appropriate program which would most adequately serve specific airline needs. Also waiting and holding space were considered as lump sums of space and will be more directly influenced by the terminal concept adopted. PROGRAM The number of airlines now serving Billings is five. The addition of three more airlines with twelve gate positions was assumed so as to create a program which would be challenging and require innovation on my part to solve site issues resulting from increased spatial requirements. It is important to address the means by which the program spaces were sized. According to the accompanying diagram, a conservative growth rate for the rest of this decade was assumed, which is con­ siderably less than the Federal Aviation projection, which generally have proven to be generous and 22 unreliable. From the 4% growth rate assumed, a figure of 450,000 enplaning passengers was calculated for the year 1990. From this figure and information provided 23 by the Federal Aviation Administration, along with an inventory of the existing facility, a hybrid program was developed. Due to the relative instabil­ ity of the airline industry, considerable effort would be necessary to project a usable document for a future airport facility, and the program to be utilized can in no reliable sense be validated. The program was in a personal sense a difficult area of the design to resolve. In part this was due to conflicting data and theories on sizing airports. PROGRAM Extrapolating the existing airport or utilizing a theory of airport planning carry with them problems and biases which are inherent. The most appropriate decisions can only be made by someone who invests much time and effort in understanding not only the problem but specific needs of the people involved. It is my hope that the final design reflects some under­ standing of the problems and provides a positive and inviting architectural environment.

It is an attempt to consolidate all airline functions into one building while minimizing walking distances for passengers. In major airport systems multiple drive to gate terminals are utilized resulting in a decentral­ ized airport system. PIER FINGER The pier finger concept is the most frequently used presently. Processing occurs in a centralized building with aircraft gate positions located along a corridor. The pier finger concept allows easy expansion without disruption to the processing area by the addition of another pier finger. This concept provides large passenger-processing capacity without excessive land requirements. PIER SATELLITE The pier satellite concept is a modification of the pier finger concept with the finger terminated in a rotunda structure with aircraft gate positions encir­ cling. The advantage of this system is that more space is available for easy assembly of passengers and is an attempt to reduce horizontal distances traveled by passengers. TERMINAL CONCEPTS REMOTE SATELLITE In the remote satellite concept allowance for aircraft to park around units separate from the main terminal occurs. Some processing (ticketing, passen­ ger assembly, aircraft loading and unloading) are performed at these units while the rest of the activities (baggage check-in, baggage claim, etc.) occur at the main terminal. This concept allows partial decentralization of processing activities. It permits flexible aircraft movement. Conveyance of passengers occurs below grade. MOBILE CONVEYANCE Mobile conveyance systems allow aircraft to be parked at remote stations away from the main terminal. A mobile conveyance system utilizing special buses or mobile lounges is used to take passengers to and from aircraft. The main feature of this system is independence between aircraft opera­ tions and terminal, and it allows flexibility in future aircraft modifications. COMMENTS These concepts, while simplistic, define in essence contemporary airport schemes.^ Most air­ ports incorporate a number of systems or utilize one in multiples, resulting in terminology such as consoli­ dated, decentralized, etc. There does not exist, though, much information about appropriateness of these schemes for specific airport needs.

In the accompanying diagram three simplified vertical schemes are examined. In the one level scheme which is presently employed in the Billings airport, airport passengers after checking in and baggage processing proceed to a second level via ramps, stairs, escalators, or elevators to waiting and gate positions. This scheme is advantageous and widely used because passengers are on the same level as aircraft entry which occurs through jetways, which are mobile telescopic circulation devices. Baggage remains on the apron level to and from aircraft. The multiple level system A is a scheme which provides minimum vertical movement for passengers as they enter the terminal at the same level as aircraft entry. Baggage after processing must be brought to the apron level. This scheme is useful if inherent to the site is a grade change of sufficient slope to help alleviate unnecessary site excavation. The site at the Billings airport is relatively flat and would not adapt to this scheme readily. VERTICAL CIRCULATION Multiple level system B is an attempt to separate arriving and departing passengers. This scheme separates opposing streams of traffic. Enplaning passengers arrive via an automobile ramp-up system to the same level as aircraft loading. Baggage as in the previous scheme must be lowered one level to an the apron. Deplaning passengers entering on aircraft level proceed one level down to baggage claim and parking, which can occur on grade or underground. The advantage of this scheme is the separation of traffic flow.
