"APPENDIX K REPAIRS TO BUILDING AND STRUCTURES DAMAGED BY THE OCCURRENCE OF A NATURAL DISASTER"

K101 Purpose. The purpose of this appendix is to provide a defined level of repair for buildings or structures damaged by a natural disaster in jurisdictions where the governor has declared a formal condition of disaster emergency under AS 26.23 by proclamation.

K102 General. Required repair levels must be based on the ratio of the estimated value of the repairs required to restore the structural members to their pre-disaster condition to the estimated replacement value of the building or structure.

K103 Structural repairs. When the ratio described in Section K102 does not exceed 10 percent, as determined by design professionals who are professional architects or professional engineers who meet the requirements of AS 08.48, buildings and structures, except essential facilities included as Category III buildings and structures in Table 1604.5 of this code, must, at a minimum, be restored to their pre-disaster condition. When the ratio described in Section K102 is greater than 10 percent but less than 50 percent, buildings and structures, except essential facilities included as Category III buildings and structures in Table 1604.5 of this code, must have the damaged structural members, including all critical ties and connections associated with the damaged structural members, all structural members supported by the damaged member, and all structural members supporting the damaged members repaired and strengthened to bring them into compliance with the force levels and connection requirements of this code. These requirements apply to those essential facilities when the ratio described in Section K102 is less than 30 percent.

Exception: For buildings or structures with rigid diaphragms where the above-required repair and strengthening increases the rigidity of the resisting members, the entire lateral force-resisting system of the building or structure must be investigated.

When, in the opinion of the building official, an unsafe or adverse condition has been created as a result of the increase in rigidity, the condition must be corrected. When the ratio described in Section K102 is greater than 50 percent, buildings and structures, except essential facilities included as Category III buildings and structures in Table 1604.5 of this code, must, at a minimum, have the entire building or structure strengthened to comply with the force level and connection requirements of this code. These requirements apply to essential facilities when the ratio described in Section K102 is greater than or equal to 30 percent.

K104 Nonstructural repairs to light fixtures and suspended ceilings. Under all ratios calculated under K102, when light fixtures and the suspension systems of a suspended acoustical ceiling are damaged, the damaged light fixtures and suspension systems must be repaired to fully comply with the requirements of Subsection 803.9.1.1 of this code. Undamaged light fixtures and suspension systems must have the additional support and bracing that is required in Subsection 803.9.1 of this code.";

(81) Appendix of the I.B.C. is revised by adding a new APPENDIX L as follows:

"APPENDIX L NORTH SLOPE HYDROCARBON PROCESSING BUILDINGS.

L101 General. These provisions have been established to provide engineering methods for the design and construction of Hydrocarbon Processing Buildings on the North Slope of this state.

L102 Scope. These standards supersede the respective requirements of the 2003 International Building Code ( I.B.C. ), International Mechanical Code (I.M.C.), and International Fire Code (I.F.C) as the minimum requirements for occupancies when designing and constructing North Slope hydrocarbon buildings in this state.

L102.2. Small unoccupied structures, shelters, and enclosures, such as well houses, meter building, and shut-down valve enclosures may be classified as a Group U occupancy if the following conditions are met:

1. The building is less than 1000 square feet;

2. The contents of the building include only meters, valves, or pipe work;

3. The building is not normally occupied more than once during a 12-hour period; and

4. If the building exceeds 250 square feet, the building has at least two exits.

L103 Basic allowable module size, height, and separation. The basic allowable module size, height, and separation for Hydrocarbon Processing Buildings must comply with Appendix L103.1 - L103.3 of this Code.

L103.1. Area and height. The maximum allowable floor area for Hydrocarbon Processing Buildings using a minimum of Type IIB construction is 10,000 square feet and the building may only be one story. The maximum allowable height shall be 65 feet; the reference datum shall be the top of the first floor framing system. Penthouse and roof structures are permitted to extend above the 65 foot height limit to meet special requirements, including aerial coolers, towers, and tower enclosures. Allowable area and building height increases permitted by Sections 504 and 506 of the I.B.C. do not apply.

L103.1.1. Service area platforms. An elevated platform or series of platforms of Hydrocarbon Processing Buildings may not be classified as a floor or mezzanine within a building, and are not subject to the requirements of Section 505 of the I.B.C . Access and egress requirements for service area platforms must be served by at least two exits per level, with one being directly to an exterior stair. Platforms must be constructed of grating-type material so that the main floor level below is visible through the platform. Upper service area platforms must be kept to the minimum size that is necessary to accomplish occasional service, operating duties, and safe egress. Virtual wall-to-wall grating on upper levels is considered a story and must be included in floor area calculations.

L103.2. Module separation. Hydrocarbon processing buildings must comply with the provisions of Subsections 501.2 as amended by this code and Subsections 704 and 721.6.2.3 of the I.B.C. , for all occupancies. Elevated pipe ways extending from a building may not be considered "extensions" of the building.

L103.2.1. Building extensions and service area platforms. Building extensions of Hydrocarbon Processing Buildings into the yard, include landings, platforms, stairs, vessels, vessel enclosures, tanks, and exhaust or intake hoods. Clear and unobstructed access for fire fighting is to be no less than 40 feet. Bridging between buildings must be designed to allow access and operation for firefighting.

L103.3. Utilidors. Utilidors are considered pedestrian walkways and must comply with the provisions of Section 3104 of the I.B.C. If such utilidors do not comply with Section 3104, they will be classified as a building and required to meet all applicable sections of the I.B.C.

L104 Stairs, Landings, Handrails, and Guardrails. Stairs, landings, handrails, and guardrails must meet the minimum requirements of 8 AAC 61, as amended as of March 9, 2001 and as amended from time to time; these regulations supersede the respective requirements of the I.B.C.

L104.1. Floor level at doors. Floors or landings may be more than one inch lower than the threshold of doorways if an attempt is made to minimize the drop through the use of ramps at interior doorways as described in Subsection 1008.3.1.6 of the I.B.C.

L105 Construction specifics. The construction of Hydrocarbon Processing Buildings must comply with Appendix L105.1 - L105.4 of this Code.

L105.1. Fire walls. When a fire wall is used to qualify under Section 705 of the I.B.C. , the wall must comply with that section. If the fire wall does not extend to the ground, the structural supports for the wall must rest upon, and be completely supported by, the pilings.

L105.2. Tank support fireproofing. Fire proofing requirements for steel tank supports, as described in Subsection 3404.2.9.1.3 of the I.F.C. (2003 edition) as adopted by reference, may be waived by the building official when justified, based on the remoteness of the facility and lack of public access, or analytical or empirical results indicating that sufficient heat could be transmitted to the permafrost to cause foundation settlement.

L105.3. Foam plastic insulated building panels. For hydrocarbon processing buildings used in the actual processing of hydrocarbons and, not normally used in other mineral extraction or manufacturing activities, foam plastic insulated building panels used on these buildings may apply a foam plastic insulated building panel thermal barrier with an index of 15. Factory Mutual approval Standard 4880 or Underwriters Laboratory (UL) Subject 1040 are acceptable tests for the purposes of approval under Subsection 2603.8 of the I.B.C.

L105.4. Electrical or communication equipment shelters and wellhead covers. Thermal barrier requirements as described in Subsection 2603.4 of the I.B.C. , are not required for fiberglass or metal covered foam panels used for construction of electrical or communication equipment shelters and wellhead covers if the following conditions are met:

1. Foam used must meet the requirements described in Subsection 2603.3 of the I.B.C. ;

2. The area of an individual shelter or cover may not exceed 1000 square feet;

3. Separation between individual shelters must be a minimum of six feet. Each wellhead must have an individual cover, but the minimum separation between individual covers does not apply;

4. The electrical or communication shelter or wellhead cover must normally be unoccupied. It is understood that operators need to spend approximately 10 minutes per day taking readings in well heads covers and that maintenance is infrequently required. The most extensive maintenance is well wireline work. This work may extend to a week per well and occur once every several years per well. Most of this work is accomplished from outside the well head cover. All maintenance is strictly controlled with a permit system;

5. The electrical or communication shelters designed with workstations in the facility do not qualify for this modification.

L106 Fire suppression. The provisions in Sections L106.1 - L106.3 establish the standards for fire suppression at North Slope Hydrocarbon Processing Buildings.

L106.1. Halon 1301 system automatic activation for gas detection. In areas of Hydrocarbon Processing Buildings where (1) both fire and explosion hazards exist, (2) both fire and gas detection systems are installed, (3) the fire and gas detection devices alarm at a continuously staffed control room and trained operators can quickly respond to the fire and gas alarms following specific fire and gas alarm response procedures, and (4) collateral fire damage is likely to be minimal, the following Halon 1301 operating activation mode is acceptable: Automatic activation of the Halon 1301 system upon gas detection coupled with manual activation of the same Halon 1301 system on fire detection.

L106.2. Manual activation of total flooding fire suppression systems. In areas where (1) the only hazard is fire, not explosion, (2) fire detection devices alarm at continuously staffed control rooms, (3) trained operators can quickly respond to the fire alarms following specific fire alarm response procedures, and (4) collateral fire damage is likely to be minimal, manual activation of the total flooding fire suppression agent is acceptable. These areas also include continuously staffed control rooms.

L106.3. Platform width. In buildings protected with fire sprinkler systems, any platform that exceeds four feet in width or length is considered an obstruction for the purposes of the installation of sprinkler systems under Subsection 903.3.1.1 of the I.B.C ".
