Project Background

Located in Old Town off Route 43 on Gilman Falls Avenue

Built in 1970 Attached to J.W. Sewall

Company hangar No renovations since

construction

Existing Terminal Conditions

• Outdated architecture and design• Thin walls

• High energy costs

Project Scope

• Conceptual airport terminal design• Aesthetically pleasing

• Modern architecture• LEED certification

http://www.old-town.org/index.asp?Type=B_BASIC&SEC={13010F93-E257-44D2-8E10-3FD834ECE4BA}

Project Scope cont’d

• Attract companies to proposed business park• Floor plan design• Structural framing• Concrete slab design• Estimated final cost

Constraints

• LEED Certification• Material selection

• Fuel tank regulations• Single story• Surrounding buildings

remain untouched

Site Inspection and Evaluation

• Outer appearance• Siding• No indication this is the

Dewitt Field Airport• Low ceilings

• 8ft high

Site Inspection and Evaluation

• Poor lighting• Fluorescent

• Thin walls• Minimal insulation

• Inner appearance• Improvements needed

Site Inspection and Evaluation

• Inefficient use of space• Half of building not in

use• Available rooms are

small

Leadership in Energy and Environmental Design (LEED)

• Green rating system designed by U.S. Green Building Council (USGBC)

• Goal to optimize energy use during and post-construction to decrease carbon footprint

LEED for New Construction Version 2.2

• Terminal design based on version 2.2

• April 27, 2009: LEED version 3 released

• Project design will need to be reviewed to meet version 3 requirements

Inspiration: Foster Innovation Center

• LEED – Silver• Modern Design• Design by Oak Point

Associates

Floor Plan Design

• Design Criteria:• Larger building footprint of 50’ x 120’• 8-9 Offices• 20-30 person Conference Room• Pilot’s Area

o Pilot’s Loungeo Full Private Bathroomo Overnight Bunking Room

• Room for expansion (e.g. Coffee Shop with Kitchen)

Floor Plan DesignTo Runway

To Parking Lot

Design Considerations

• Usage of Facility• Airport personnel, pilots, business employees, and

general public• Separation of Airport and Rented Space

• Offices on one side with terminal opposite• Efficient Usage of Space

• Create inviting space for business, reduce unused area• Open, Wide Entry Hallway

• Easy access to entire terminal with inviting seating for occupants

Engineering Design

• Design based on• Client’s concerns• LEED constraints• Loading factors

• ASCE 7 Minimum Design Loads for Building• 2006 Building Code Handbook• AISC Steel Construction Manual 13 Edition• ACI 318 Building Code

Loads

• Wind Load• ASCE 7 Section 6.0• Class C exposure at 17

ft ave. roof height – 14.7 psf

• Dead Loads• Live Loads

• ASCE 7 Section 4.0• Office Use – 100 psf

• Snow Load• ASCE 7 Section 8.0• Old Town, ME – 60 psf

Steel Frame Design

• Light gauge steel roof trusses• Large 50 ft span• Recycled steel for LEED point• “Modern” feel

• W18x57 beams, 25’ spans• Type 5 Standard Pipe columns

spaced at 25’• Flexible floor layout• Again keeping in mind the “modern” feel

Concrete Slab Design• Reinforced Concrete Slab

• F’c = 3000 psi• 6” slab, #4 bars at 10”, temperature and shrinkage

reinforcement #3 bars at 12”• Reinforced Concrete Footings

• F’c = 3000 psi• Loads from column• Loads from concrete slab• 4’-4” square footing, 13” high, 8 - #4 bars evenly

spaced

Material Considerations

• Material selection based on LEED guidelines• Rapidly renewable• Low VOC substitutes for conventional products

• Paints, adhesives• Recycled materials

• Aluminum roofing• Carpet tiles

• Sustainable materials

Cost

• Exterior cost• Approximately $115,000

• Interior cost• Approximately $86,000

Total Terminal Cost

• Approximately $1.2 Million • Includes the following:

• Site work• Masonry• Equipment• Plumbing• HVAC system• Electrical• Engineering/Architectural Fees
