CLIN 003 – Install CAT 5 TDI Hurricane-Resistant Design, non- decorative shutters.

a.0 Ten (10) New Shutters must withstand hurricane-force winds. Source Bahama shutters and coordinate with area suppliers and ensure intrusion security. Provide durable, corrosion-resistant Bahama-style hurricane shutters to protect the structure’s windows from hurricane-force winds and potential intrusion during long unoccupied periods. The shutters should be low-maintenance and mechanically operable to suit the lack of electrical power at the site.

1.0 Bahama shutters comply with the Building Code for High Velocity Hurricane Zones, Texas Department of Insurance (TDI) regulations, and ASTM impact testing approvals. The shutter assembly must have ability to be raised into an open position. The shutter assembly must be lowered into the closed position during a hurricane event. The shutters may be installed as a single panel configuration or as a multi panel configuration. When the storm bar is utilized, the maximum width is limited as specified in the manufacturer’s drawings.

2.0 Corrosion Resistance Material: Stainless Steel or Powder-Coated Aluminum, specifically designed for marine environments. Aluminum shutters should be powder-coated to resist corrosion, and resistance against salty moisture exposure. Color approved by Park.

3.0 Security Features Lockable design: When unoccupied, shutters must be lockable for intrusion resistance. If a factory lock is unavailable, contractor to provide a fabrication solution, such as a padlock mechanism or additional security feature, to secure the shutters effectively.

4.0 Low Maintenance - Required Non-electric operation with easy robust manual adjustment to open and close. Shutters should require minimal upkeep due to the absence of electrical power on-site.

b.0 Installation Requirements:

1.0 Install Bahama shutters directly over each of the ten (10) windows, ensuring correct top-hinge configuration.

2.0 Secure shutters to the structure using stainless-steel corrosion-resistant screws, bolts, and hardware.

3.0 All penetration points shall be properly sealed and weatherproofed to meet existing building specifications.

4.0 Use maximum anchor spacing including top female hinges according to CAT 5 Hurricane-Resistant Design for installation into wood southern pine.

5.0 Identify maximum shutter span and maximum shutter width according to CAT 5 Hurricane-Resistant Design.

6.0 Install shutters in accordance with regional hurricane protection codes and any additional structural specifications.

7.0 Verify that all installed shutters function as intended, providing both storm protection and intrusion security.

c.0 Hardware and Accessories:

1.0 Use all corrosion-resistant stainless steel materials, including hardware for hinges, locks, and any required reinforcement.

2.0 Shutter supports should ensure they are sturdy and withstand both lateral and upward wind loads. Bahama shutters shall have Locking Rod.

3.0 Custom Security Lock Fabrication Coordinate to add lockable functionality if factory-installed locks are unavailable. Confirm with the CO on custom lock fabrication, using a padlock option if necessary.

4.0 All screws to be stainless steel series with required strength by the manufacturer and shall comply w/ Texas building code.

5.0 Bolts to be series stainless steel with required strength by the manufacturer.

6.0 All aluminum pop rivets to be aluminum alloy with aluminum mandrel.

7.0 Anchors to wall shall be as per manufacturer requirements.

1.0 OPTIONAL WORK / TASKS:

OPTION 001 – Construct Cabin Ramp Extension.

a.0 Construct a new ramp extension attached to the existing cabin to improve accessibility. Reference “Attachment 2 Ramp Extension” plan. See “att1 PAIS Cabin 1.25.23 - AS BUILTS”.

1.0 Includes two new landings, two new ramp runs, and the integration of Government-Furnished Equipment (GFE) aluminum ramp to the existing grade.

2.0 The design and construction shall adhere to specifications outlined in the as-built drawings and comply with the details provided below.

b.0 Structural Components

1.0 Joists and Decking: Joists: Minimum 2x8 pressure-treated lumber, spaced 16 inches on center (o/c). Deck Boards: 2x6 pressure-treated decking boards, securely fastened to joists.

2.0 Handrails. Posts: 4x4 pressure-treated posts lag-screwed to the rim joists with a minimum of (2) 5-inch A307 lag screws (1/4-inch diameter minimum) or equivalent structural screws. Posts must extend at least 4 inches onto the rim joists. Handrails consist of 2x4 top, middle, and bottom rails. Top cap to be installed at a minimum height of 36 inches above the deck boards. 4x4 columns must be positioned to prevent rail deflection. Install handrails as detailed in as-built drawings. Not explicitly shown in the new ramp extension plans.
