Per your request we recently performed a survey of the above referenced site for the purposes of verifying the existing conditions for a roof replacement proposal. During the survey two core cuts were taken to verify the roofing components above the roof deck. The following was found at each of the locations: 1. Asphalt built up roof membrane with gravel surfacing 2. ½” wood fiber insulation sprinkle mopped with hot asphalt 3. Plywood roof deck The plywood roof deck is supported by joists that run east to west that are supported by 5 beams that run north to south. Venting in the soffit on the east and west elevations indicate that the joist space below the roof deck is insulated. The main roof appears to be structurally sloped to the NW corner where a scupper and downspout assembly direct water into an inground receiver. A flange drain is located near the NE corner. We believe the intent of the flange drain is to be the overflow for the scupper on the NW corner. The entrance roof located on the west elevation appears to be flat and may retain water. Its drainage is via two scuppers that dump the water onto the parking area below. No downspouts are currently in place for these two scuppers. As the main roof appears to drain adequately as currently constructed the base bid for the project will be to remove the existing BUR system down to the plywood roof deck then insulate with flat stock insulation above the roof deck to meet a minimum R30. Removal of sections of Contract # 2020-3053 Page 2 of 7 4550 Main Street NE - Minneapolis, MN 55421 (763)572-0660 - Fax (763)572-0230 www.centralroofing.com wood soffit on the east and west elevations will be required to allow access to the vent openings into the joist space. The vent openings will need to be insulated with either fiberglass insulation or low-rise urethane foam insulation. An add alternate will be included in the proposal that includes 1/8” per foot tapered insulation to the scope of work. The insulation for the add alternate will provide and average R30 insulation upgrade. As part of this alternate a 18” tall 2x6 stud wall needs to be constructed around the perimeter of the main roof area to provide an adequate flashing height at the perimeter due to the extra thickness of the insulation. The scope of the roof replacement is also to include new metal flashings. As part of the roof installation, the wood blocking a the east, south and west perimeter edges of the main roof aera is to be removed to the extent to allow new wood blocking to be installed out flush with the edge to eliminate the existing ledge. The new metal flashings are to include cladding the entire fascia and a UC500 style unvented panel is to be installed over the existing soffit. The new soffit panels are to be set on hat channels to allow a space for relocation of the electrical lines for the new lighting. On the north elevation, the Heights Liquor store butts up against the neighboring building. Currently, the connection of the two roof assemblies is suspect and water is accessing the space between the buildings. At this location, the metal siding panels on the adjacent building should be removed. A new roof to wall expansion joint should be constructed to properly connect the waterproofing of the two buildings’ roof assemblies (see the attached detail). The upgrade to the building is also to include a new marquee façade on the front entrance roof. The marquee will consist of new parapet walls on the three exterior sides of the entrance roof (see the attached preliminary drawings). As the new parapet walls are to be 4 to 6 feet tall the new construction will cause the roof area to be inset and hold snow. Therefore, the new design is to include 2x10 roof joist and a ¾” plywood roof deck to create a new roof deck that slopes back onto the existing main roof area. Note the new roof deck installation is not currently included in the attached drawings. Minimum slope of the new deck to be ¼” per foot. The exterior of the new walls to be clad with a metal siding panel similar to a UC-500 panel. The interior of the walls is to be waterproofed above the new BUR flashings with ice and water shield and 24 ga. pre-finished counter flashing metal. There are two mechanical units currently set on the roof. They are not supported by curbs. These units will need to be temporarily disconnected and set on curbs/sleepers that are flashed into the roof. Further, the electrical lines for the existing exterior lighting has been installed on the wood fascia. This will need to be disconnected to allow the new fascia metal to be installed. We have met with Brian Kovar of Aid Electric and Tom Sahli with Horwitz Mechanical at the site to review the existing conditions. Brian noted that the existing lights on the west elevation have Page 3 of 7 4550 Main Street NE - Minneapolis, MN 55421 (763)572-0660 - Fax (763)572-0230 www.centralroofing.com not been upgraded to LED lights. The electrical pricing includes replacement of these lights. The electrical pricing also includes a new electrical circuit and auto functioning heat trace cable for the downspout. The cost provided for the electrical modification is $2,795.00. The cost provided for the mechanical modifications is $4,870.00. These costs have been included in the proposal below. As part of the interior remodel the enclosure for the mechanical equipment located on the east elevation is to be opened up, reinsulated and new plywood sheathing installed. That work is to be part of the interior remodel scope of work and its cost are not included. The roof replacement scope of work is to include retuning to the site once they are complete and installing underlayment and a UC500 style vertical panel on the enclosure. Additionally, the remodel is also to include painting the interior of the storefront windows on the west elevation. The roof replacement scope of work is to include infilling a 2x6 stud wall against the exterior of the windows. The inside of the new stud wall to be clad with type X gypsum board (for fire rating). The exterior of the stud wall to be clad with ¾” plywood. Infill stud wall with fiberglass batt insulation. Waterproofing of stud wall is to be ice and water shield and 24- gauge pre-finished metal panels (similar to UC-500 panel). Pricing for window infill to be supplied as an add alternate.

AGENDA SECTION ITEMS FOR CONSIDERATION ITEM NO. MEETING DATE NOVEMBER 30, 2020 CITY OF COLUMBIA HEIGHTS - COUNCIL LETTER CouncilLetter_Resolution2020-107_Store3RoofReplacementt_113020.docx ITEM:RESOLUTION 2020-107, AWARDING TO A CONTRACT TO CENTRAL ROOFING COMPANY FOR ROOF REPLACEMENT AT MUNICIPAL LIQUOR STORE NO. 3 FOR $100,020 WITH OPTIONAL ALTERNATES, AND TO AMEND THE LIQUOR FUND BUDGET ACCORDINGLY. DEPARTMENT: Finance CITY MANAGER’S APPROVAL: BY/DATE:Joseph Kloiber/ November 24, 2020 BY/DATE: CITY STRATEGY: #6: Strong Infrastructure/Public Services Additional Strategy? #3: Economic Strength SHORT TERM GOAL (IF APPLICABLE Additional Goal? N/A BACKGROUND: Prior city council actions related to this item include: ·Award of a contract for $9,500 to Buetow2 Architects to design, seek bids, and provide contractor oversight for a project to remodel and update liquor store 3 at 5225 University Avenue NE. ·Approval of a $200,000 budget to remodel and update liquor store 3 at 5225 University Avenue NE. During the architects’ analysis of the store 3 building, they determined that the roof needs to be replaced. It would not be advisable to invest in the remodel and update project without replacing the roof to extend the remaining useful life of the building. Staff is only aware of routine maintenance being performed on the roof since the building was constructed in the 1960’s. Staff obtained proposals for replacement of the roof from two contractors the City has successfully done business with previously. Copies of those proposals and a comparison of their features are attached to this council letter. Staff determined that the proposal from Central Roofing was the most favorable. Both roofing proposals are for approximately $100,000 after factoring in temporary removal and reinstallation of electrical and HVAC components on the roof. A portion of the roof work will provide some of the aesthetic improvements intended by the original remodeling project, such as construction of a marquee-style façade over the building entrance, as well as wrapping the existing building trim with pre-finished metal. Of course, a majority of the proposed roof work provides required structural repairs that are well beyond the scope of just remodeling and updating. The architect’s current estimate for the remainder of the project other than the roof is from $125,000 to $140,000. When combined with the portion of the roofing work that will provide aesthetic improvements intended by the original project, the remodeling project is still within the $200,000 budget approved by the city council. An additional budget appropriation should be approved however, to fund the repairs that are beyond the scope of the remodeling activities. City of Columbia Heights - Council Letter Page 2 CouncilLetter_Resolution2020-107_Store3RoofReplacementt_113020.docx STAFF RECOMMENDATION: Staff recommends approval of the following motions. RECOMMENDED MOTION(S): Move to waive reading of resolution 2020-107, there being ample copies available to the public. Move to adopt resolution 2020-107, awarding a contract to Central Roofing Company for roof replacement at municipal liquor store no. 3 for $100,020 with optional alternates, and to amend the Liquor Fund budget accordingly. RESOLUTION NO. 2020-107 AWARDING A CONTRACT TO CENTRAL ROOFING COMPANY FOR ROOF REPLACEMENT AT MUNICIPAL LIQUOR STORE NO. 3 FOR $100,020 WITH OPTIONAL ALTERNATES, AND TO AMEND THE LIQUOR FUND BUDGET ACCORDINGLY Whereas, City Council has adopted a $200,000 project budget by prior resolution to significantly improve the physical appearance of the City’s municipal liquor store no. 3, located at 5225 University Avenue NE; and Whereas, the original project budget did not include the replacement of the building’s roof system; and Whereas, architects under the City’s direction have subsequently determined that the age and condition of the building’s roof requires replacement of the roof system; and Whereas, City staff estimate that the original project, when combined with replacement of the roof, would still provide the desirable benefits of increased sales and profitability exceeding both project costs and future repair costs over a reasonable number of years; and Whereas, City staff have followed City and state requirements for soliciting proposals from responsible contractors for this roof replacement; Now, therefore, in accordance with all ordinances and regulations of the City of Columbia Heights, the City Council of the City of Columbia Heights makes the following: ORDER OF COUNCIL It is hereby resolved, that a contract is awarded to Central Roofing for roof replacement at municipal liquor store no. 3 for $100,020 with optional alternates, and that the Liquor Fund budget is amended accordingly. Passed this 30th day of November, 2020 Offered by: Seconded by: Roll Call: _________________________________ Mayor Donna Schmitt __________________________________ Nicole TIngley, City Clerk City of Columbia Heights Comparison of Store 3 Roof Replacement Proposal Central Flynn Base Quote 100,020$89,334$ electrical (2,795)Not included mechanical (4,870)Not included 92,355$89,334$ Staff comments: The main roof proposed by each bidder is substantially the same. Central's base quote includes constructing the new marquee-style façade over the entrance to the building. Flynn's base quote does NOT include constructing the new marquee-style façade over the entrance to the building. This more than accounts for the 3% difference in the propsals, and therefore the proposal from Central is lower cost when comparing "apples-to-apples." Central's bid document and overall approach to the project are also more comprehensive. Similar to a general contractor, they have coordinated in advance with the electrical, mechanical, and architectural providers. This could be indicative of reduced risk on the project timeline. Staff recommends acceptance of Central's proposal.

As you said, coordinate with Eric on the details and needs. Have a good day! David On Tue, Dec 1, 2020 at 7:12 PM Joseph Kloiber <JKloiber@columbiaheightsmn.gov> wrote: Heartland Tire, Inc. David Mitchell, President 6885 139th Lane NW, Suite 1900 Ramsey MN 55303 CC: Eric Glassmaker, Store Manager David: The City of Columbia Heights has contracted with Central Roofing Company to replace the roof on the liquor store the City owns at 5225 University Ave NE in Columbia Heights. As you know, this liquor store butts up to the Heartland Tire store to the north at 5229 University Ave NE. Consequently, there are a couple aspects to the City’s project that would impact Heartland’s store. Although I’m fairly confident you will find these to be favorable impacts; the City, as a good neighbor should, requests your approval before proceeding with the work. 1) There are communications cables that run from a utility pole in the alley behind the stores, first to the northeast corner of the City’s building (near the roof line) and then run to the southeast corner of Heartland’s building. The significant number of these cables suggest that several are abandoned and no longer in service. It appears however that one or more of these cables are currently providing service to Heartland’s store. We propose to have your communications service provider(s) relocate your active cables to run directly from the utility pole to Heartland’s building and terminate any abandoned cables at the utility pole. This will enable the roofer to complete the necessary work in the northeast corner of the liquor store, as well as make Heartland’s communications system independent from the City’s building. Of course it is also a shorter cable run to go directly from the utility pole to Heartland’s building. I would coordinate this aspect of the project with Eric Glassmaker, your store manager, to address his concern to avoid interruptions in communications service. 2) The contractors have discovered that the portion of the roof where the two buildings meet has an issue that allows water penetration down between the walls of our two buildings. Below is the section from their report that addresses this issue. The detailed drawing they refer to is attached to this email: On the north elevation, the Heights Liquor store butts up against the neighboring building. Currently, the connection of the two roof assemblies is suspect and water is accessing the space between the buildings. At this location, the metal siding panels on the adjacent building should be removed. A new roof to wall expansion joint should be constructed to properly connect the waterproofing of the two buildings’ roof assemblies (see the attached detail). The cost to construct this new roof-to-wall expansion joint will be paid by the City as part of its overall contract with Central Roofing. The City just needs to know that you are ok with this part of the project. At your earliest convenience, please let us know if these proposed actions meet your approval. If the weather permits, the contractor will complete the work this winter in preparation for other rehab of the liquor store in the Spring of 2021. If you have any questions that I can address, let me know. If you have a more technical question about the project, you can contact Jon Meyer directly at Central Roofing JMeyer@centralroofing.com (763) 572-0660.
