BREIVIK ENGINEERS, INC. <br />STRUCTURAL. CIVIL AND FORENSIC ENGINEERING <br />2999 YORKTON BOULEVARD Sy. PAUL, MINNESOTA 55117 <br />(612)482.9500 <br />Sept. 30, 198E <br />Mr. Mark Finneman <br />Finn -Daniels <br />4175 Lovell Rd. <br />Lexington,, MN. 55112 <br />RE: Casci Complex <br />Roseville, MN. <br />Edge wall at podding area detail. <br />Dear Mr. Finneman, <br />The cast concrete wall detail shown as an edge to the storm <br />water detention pond is, in my opinion, a satisfactory detail <br />which does not compromise safety or increas, deterioration. <br />The concern of the city staff, is assumedly, i:he impact of <br />the freeze)'thaw process on the integrity of the wall. Its <br />use as a pond occurs in warm weather and does not effect <br />either the wall design or footing design. The detail, <br />without brick, indicates a 16" wall with 6" of cover over <br />vertical reinforcing on the pond side. The building code <br />requires a minimum of 2" of cover for concrete exposed to <br />earth or weather. Even if the brick veneer is used in lieu <br />of the concrete. The 2" cover required by the code still <br />exists. Water is typically moved away from foundations of <br />any type, not because of the consequence to the wall itself, <br />but because of the possible passage of water into the area <br />behind the wall. This wall meets the building code and is of <br />proper construction. <br />Even the application of brick can provide a serviceable wall. <br />The brick should be grade SW (severe weather) the joints <br />tooled tightly, weeps installed along the bottom of the brick <br />and a coat of silicone sealer added. The greatest <br />consequencr)s (gi•-en the maximum exposure to water) would be <br />the possible to,-,�-c"nting of joints several years from now. <br />If it becomes .nt to maintain brick on this part of the <br />elevation, the. system desc-ir ',,bed above, should be <br />considered reas.— ble with a minor maintenance <br />qualifications. <br />Please let me know is any odditional information is required. <br />Very Truly Yours, <br />1 <br />A.
