GENERAL REQUIREMENTS

Existing Campus Background

The Flagler Executive Airport (FIN) is a county-owned, public use, general aviation airport operated and maintained under the Flagler County Board of County Commissioners. The airport accommodates more than 175,000 general aviation takeoffs and landings each year. There are no scheduled airlines providing service to the airport.

Located on the east side of Flagler County on State Road 100, the airport sits at the gateway to natural attractions, golf courses, and pristine beaches just four miles away. The airport comprises over 1,465 acres, bordering the City of Palm Coast. It is a towered field with two intersecting runways -- Runway 11-29 (5,500' x 100') and Runway 6-24 (5,000' x 100') -- and a water runway, Runway 18W-36W (3,000' x 500'), on Gore Lake within the airport property.

Existing Air Traffic Control Tower (ATCT)

The existing Air Traffic Control Tower is a seven (7) story facility of approximately 4,375 GSF and is a 25FT-by- 25FT precast concrete structure (4-sided) with a 6-sided cab floor at the top for air traffic control crew members to observe the 360 degree view of the airport. Floors are poured concrete, exterior walls are painted concrete tilt-wall panels, and the roof is a trapezoidal panel, standing seam mansard metal roof system with a modified bitumen membrane roofing system over tapered insulation board system. Other features include laminated double glazing within a storefront frame around the cab level, a concrete catwalk (flush metal panel system over steel beams below) with galvanized steel guard railing and metal wall panels at the top of the cab.

STRUCTURAL

General Requirements

The air control tower structure was constructed with precast concrete wall panels. The cab was constructed with steel framing. The floor beams of the tower consisted of wide-flange steel beams that cantilevered off the main tower concrete walls to support the catwalk. The catwalk was constructed with galvanized steel deck and a reinforced concrete slab. The catwalk perimeter had steel guardrails.

Existing Conditions

The steel wide-flange beams that supported the perimeter of the catwalk, and the main support beams that cantilevered off the tower walls, had multiple areas that were severely corroded with section loss, delaminated steel, and were structurally compromised. The corrosion appeared generally limited to the area underneath the catwalk, as the steel framing underneath the tower was partially protected by spray-on fireproofing.

It is our opinion that the catwalk steel framing was in very poor condition and unsafe. All the steel framing extending outward from the tower will need to be removed and replaced. It is our recommendation that a different catwalk design be considered, consisting of aluminum beams bolted to the existing steel moment connections, fiberglass or aluminum structural grating, and aluminum guardrails. This design greatly lightens the dead load by eliminating the concrete slab, which will also reduce construction costs. Aluminum offers far superior resistance to corrosion than steel, and the open grating would allow water to freely drain and also allow for drying of the aluminum framing.

Scope of work items are listed in RED.

Photo #1: Aerial view of the tower and arrow indicating the northeast corner. Reference Photo #2.

Photo #2: Reference Photo #1. View of the northeast corner of the top of the tower concrete walls. The concrete was cracked and spalled. Remove all cracked, spalled, and unsound concrete and inspect rebar for corrosion. Clean rebar and replace/repair as required. Replace concrete with approved patching compound by Sika or similar.

Photo #3: Typical view of the steel framing along the perimeter of the catwalk. Steel was severely corroded throughout the perimeter of the catwalk and at multiple locations underneath the catwalk. The entire catwalk is considered structurally unsound and beyond repair and will have to be completely replaced with a similar system, though we recommend consideration of aluminum framing.

Photo #4: Typical view of a removed section of corroded and delaminated steel from the catwalk framing.

Photo #5: Typical view of the underside of the catwalk and the steel framing. The steel framing directly underneath the tower generally exhibited signs of minor corrosion, with some areas of more advanced corrosion. It appeared that spray-on fireproofing had protected much of the steel framing underneath the tower. Clean off all corrosion with wire brush or other method and reinspect steel framing.

Photo #6: View of the underside of the southwest corner of the catwalk and the steel framing. This condition was observed at several locations, where there was severe corrosion and delamination of the main support beams. The cantilevered beams were bolted at the tower walls and appeared they could be removed and replaced with aluminum or steel, reference Photo #7.

Photo #7: Reference Photo #6. It appeared the cantilevered support beam was connected underneath the tower via a moment connection. The cantilevered beams were bolted at the tower walls and appeared they could be removed and replaced with aluminum or steel.

Photo #8: Underside of the southwest catwalk, moderate level of corrosion observed on the steel framing on top of the tower walls. Clean off all corrosion with wire brush or other method and reinspect steel framing. Relatively minor repairs such as welding on additional steel may be required.

Photo #9: Underside of the northwest corner of the catwalk, moderate level of corrosion observed on the steel framing and deck. Clean off all corrosion with wire brush or other method and reinspect steel deck. Relatively minor repairs such as welding on additional steel deck may be required, beam indicated by left arrow to be replaced.

• ISO 11600F 25LM

• EN15651 – CE MARK

• ASTM Specification C 920, Type S, Grade NS, Class 100/50, Use T, NT, M, G, A, and

How to Use Surface Preparation Ensure that surfaces to be sealed are clean, dry, sound and grease-free. Porous substrates such as concrete, brickwork, mortar, etc. must be mechanically cleaned of loose particles using a steel brush, sanding disc or any similar means. Clean non-porous surface with DOWSIL™ R-40 Universal Cleaner, dry thoroughly with a clean, lint-free cloth and wait for at least half an hour before application of sealant.

Note: When using any solvent, always provide adequate ventilation. Avoid heat, sparks and open flames. Use solvent resistant gloves. Observe and follow all precautions listed on solvent container label.

Masking Areas adjacent to the joints should be masked with tape to prevent contamination of the substrates and to ensure a neat sealant line. Masking tape should be removed immediately after tooling.

Priming Primers are not usually required on stone, concrete and masonry substrates. On non-porous substrates such as anodized aluminum, priming might be needed. It is recommended to carry out test on such substrates to assess the need for priming. A suitable primer on non-porous substrates is DOWSIL™ 1200 OS Primer. Allow at least half an hour between priming and sealant application. Please contact Dow’s technical service in case of doubt.

How to Use (Cont.) Back-up Materials Where back-up material is required, open cell backer rod is recommended. Back-up materials provide back pressure and avoid three sided adhesion that limits sealant movement capability.

Finishing The joint should be tooled within 5 minutes of application to ensure good contact between the sealant and the substrate. Tooling of the sealant also gives a smooth, professional finish.

Clean-Up If sealant is misapplied to porous substrates, it should be left until it is just cured and then removed by peeling, cutting or other mechanical means. Care should be taken not to damage plastic or coated surfaces.

Joint Design The sealant joint width should be designed to accommodate the movement capability of the sealant. When designing joints using DOWSIL™ 790 Silicone Building Sealant, the minimum width should be 6 mm. For joints between 6–12 mm wide, a seal depth of 6 mm is required. For joints above 12 mm wide, a width to depth ratio of 2:1 should be used. As the sealant joint width becomes larger than 25 mm, the depth should be held at approximately 9 mm to 12 mm. In situations where fillet joints are needed, a minimum of 6 mm sealant bite to each substrate is recommended. For joint dimensions with a width greater than 25 mm or a depth greater than 15 mm, please contact your regional service centers for technical assistance.

Usable Life and Storage

When stored at or below 32°C, DOWSIL™ 790 Silicone Building Sealant has a shelf life of 12 months from date of manufacture. Refer to product packaging for “Use By” date.

Limitations DOWSIL™ 790 Silicone Building Sealant should not be applied:

• In structural applications.

• Below grade or to materials that outgas, which can cause bubbling in curing sealant.

• On brass or copper or other similar material that can be corroded.

• To surfaces that are continuously immersed in water.

• For use as an interior penetration firestop sealing system.

• To building materials that bleed oils, plasticizers, or solvents – materials such as impregnated wood, oil based caulks, green or partially vulcanized rubber gaskets, or tapes or bituminous below-grade waterproofing and asphalt-impregnated fiberboard.

• In totally confined spaces because the sealant requires atmospheric moisture for cure.

• To surfaces that will be painted after application. The paint film will not stretch with the extension of the sealant and may crack and peel and most likely will not adhere to the sealant.

• To surfaces in direct or indirect contact with food.

Page 4 of 4 ®Trademark of The Dow Chemical Company Form No. 62-2147-01-0220 S2D

Limitations (Cont.) • To wet or frost-laden surfaces.

• In applications where solvents or primers are not fully dried prior to sealant application.

Uncured sealant is very sensitive to many solvents, primers, and cleaning agents; these may cause the sealant to remain uncured or tacky.

Description DOWSIL™ 795 Silicone Building Sealant is a one-part, neutral-cure, architectural-grade sealant that easily extrudes in any weather and cures quickly at room temperature. This cold-applied, non-sagging silicone material cures to a medium modulus silicone rubber upon exposure to atmospheric moisture. The cured sealant is durable and flexible enough to accommodate ± 50 percent movement of original joint dimension when installed in a properly designed weather seal joint. In a properly designed structurally glazed joint, the sealant is strong enough to support glass and other panel materials under high wind load.
