City of Pequot Lakes WIDSETH <br /> Maintenance Dept. Facility Addition SMITH <br /> Feasibility Study 11i <br /> Page 2 NOLTING <br /> Architectural Summary <br /> This review is based on the 2015 MN State Building Code,the 2012 International Building Code(IBC)and <br /> the International Existing Building Code(iEBC). Although the city has not adopted the State Building Code <br /> they are still required to comply with accessibility,plumbing and electrical requirements. <br /> Allowable Area(MSBC Chapter 5): <br /> During our on-site review, it was observed that there is an existing fire wall separating the parking garage <br /> area and the front office area. The parking garage portion of the existing facility and proposed addition <br /> were reviewed in general to determine whether they meet the allowable area requirements of the building <br /> code and whether any additional modifications would be required. The parking garage portion of the <br /> building is 15,817 sq. ft. in area. The construction type would be a Type V-B construction,which <br /> consists of any materials permitted by code. A parking garage is classified as an S-2 occupancy with an <br /> allowable area of 13,500 sq. ft. However,this amount can be increased based upon the amount of open <br /> space surrounding the building. <br /> When the formula for allowable area increases(factoring unsprinkled) is applied to the parking garage <br /> portion of the facility,the maximum area allowed is 19,575 sq. ft.,which is greater than 18,617 sq. ft. <br /> (15,817 sq. ft.existing+2,800 sq. ft.addition)area. The total of the existing and proposed building areas <br /> is within the limits allowed by code and would be compliant. <br /> Height(MSBC Table 503 <br /> A building with an S-2 occupancy cannot exceed two stories or 40 feet. The existing parking garage area <br /> and proposed addition is two stories and under 40 feet tall and is in compliance. <br /> Occupancy&Required Separations(MSBC Chapter 3 and Section 508): <br /> The primary occupancy of the parking garage area is S-2. The existing meeting room is classified as an <br /> A-3 assembly occupancy and the office area is classified as an accessory occupancy to the primary <br /> occupancy. These spaces are not required to have any fire separations between the different occupancies <br /> and are in compliance. <br /> Fire Protection (IEBC Chapter I 1 and MSBC Chapter 9): <br /> An automatic sprinkler system shall be provided throughout existing fire areas increased by an addition as <br /> well as the addition where the fire area of the enclosed parking garage exceeds 12,000 sq. ft. As stated <br /> above the parking garage portion of the existing building is 15,817 sq. ft.which exceeds the maximum <br /> allowable fire area and is not compliant. Therefore,an automatic sprinkler system would be required in <br /> the existing parking garage area as well as the addition. Requirements of the system are listed in the fire <br /> protection portion of the mechanical systems summary. <br /> An alternate option in lieu of installing an automatic sprinkler system would be to construct a separate fire <br /> wall just to the north of the existing north exterior wall with opening(s)protected by rolling coil fire <br /> door(s). The existing fire area would then not be increase and a sprinkler system would not be required. <br /> However,through our experience the cost to build the fire wall with coiling door(s)typically has been <br /> higher than installing a sprinkler system and does not provide the additional incentives such as increased <br /> allowable areas and exit travel distances as well as potential insurance credits. <br /> JA013013-City Of dequot Lakes\0130B0057-Maintenance Facility Addition And Salt Shed Study\013080057.000-Maintehance Facility Addition And Salt Shed Study\Reports\Feasibility Study.Docu <br />
