Renovation of a playground / park / athletic field in Milwaukie, Oregon. Completed plans call for the renovation of a playground / park / athletic field.

Aquatic Park Stair and Deck Repair Project Project Estimate: $75,000.00 - $100,000.00 North Clackamas Parks and Recreation District ("NCPRD"), is seeking labor and materials to provide removal, repairs and replacement of concrete decking and stairs related at the North Clackamas Aquatic Park located at 7300 SE harmony Rd, Milwaukie, Oregon, 97222. Detail 1/S200 FIRST FLOOR REPAIR EXTENS PLAN o See detail 1/S300 shown hatched for extents of slab to be evaluated and patched. If compromised material is found to be greater than that shown in detail 1/S300, notify engineer of record prior to further removal. Contractor to provide quotes based on a price per assumed square foot to allow for clear additional cost per foot if more than the assumed extent of repair is uncovered during the evaluation and demo performed by the contractor. o Remove and replace existing CMU partition wall where the access door is located like for like as required. Note the curved wall is not a partition wall and shall not be modified. See detail 1/S200 for location of partition wall below the stairs. o Repair pipe penetration causing significant deterioration of slab and edge beam concrete. Remove compromised material at slab and face of edge beam below as required to find competent material. Notify Engineer of record the extent of compromised material at the face of the edge beam prior to patching. Additional repair detailing may be required. o Estimated Extent of slab replaced per detail shown at 2/S300shown shaded. o If compromised concrete is more significant than allowed per the patching detail 1/S300 at the location, additional strengthening and details will be required to support the curved CMU wall. Notify Engineer of record as required. o Provide #5 X 4'-0" corner bars centered in slab at each corner. Dowel bars into wall similar to typical slab reinforcing on 2/S300 Detail 2/S200 STAIR REPAIR PLAN o Contractor shall clean away all corrosion and verify no loss of steel section occurs at other stairs and landings support locations. Notify Engineer of record if locations of loss of section are uncovered. Otherwise, apply new corrosion inhibitor to supports. Verify all existing steel angle supports have minimally (2) anchors. Provide new, additional, anchors similar to 3/S301 as required, typical, below all stairs and landings. o Locate pipe penetration causing significant deterioration of slab. Remove compromised material at slab as required to find competent material. Notify Engineer of record the extent of compromised material at the slab and slab support prior to patching. Additional repair detailing may be required. o Estimated extents of landing to be repaired shown per detail 2/S301 shown as hatched. o Existing deck support beam below stair landing. Mechanically clean beam and welds of all corrosion and verify loss of section has occurred and existing welds are in good condition. Notify Engineer of Record if sections appear to be compromised or the welds appear to be in poor condition. o Add additional L 6"X4"X3/8 framework angle anchor at end of ledger similar to 3/S301 o Estimated extents of stairway slab to be replaced shown in 1/S301 shown shaded. Detail 1/S300 TYPICAL SLAB REPAR o Mechanically remove all loose and compromised concrete until competent concrete is exposed. o Mechanically remove deteriorated metal and corrosion from exposed reinforcing down to competent steel. Verify diameter has not been reduced by more than 10% and apply any corrosion inhibitor prior to patching with repair mortar. If Diameter is reduced by more than 10% notify Engineer of Record. o Mechanically remove all loose and compromised concrete until competent concrete is exposed at bottom of slab. Verify thickness of removed concrete is not greater than 1/2 " and that bottom reinforcing is not corroding. Otherwise notify Engineer of Record prior to patching or removing material further. o Concrete Surfacing Notes Grade all surfaces to match existing or consult waterproofing expert for improved grading to drain. Provide non-slip broom finish to top of surface. o Remove excess material. Detail 2/S300 TYPICAL SLAB REPLACEMENT *Specific replacement information is schematic and is based on PSE's experience with similar structures and is for Preliminary Bidding Purposes Only. The final replacements and repair design may change pending final design and calculations.* o Mechanically remove deteriorated metal and patch per 1/S300 at #4 edge beam reinforcing and #8 interior beam reinforcing. If diameter is reduced by more than 10% notify Engineer of Record prior to patching. o New bars at 6" on center, centered between existing bars, with cover and embedment shown on sheet S300 2/S300. Use Simpson pure 220+ epoxy at existing concrete and apply corrosion inhibitor. o Mechanically remove all loose and compromised concrete above beams until competent concrete is exposed for a min depth of 3" and a max depth of 5" notify Engineer of Record prior to removing more than 6" of concrete on top of beams. o Verify existing CMU is competent above and below slab. If CMU is determined to be comprised, notify the engineer of record and additional repair details may be required. o Roughen all surfaces between new and existing concrete and apply bonding agent, typical. o Verify existing bars that dowel into edge of beam do not have loss of section. Clean and apply corrosion inhibitor. o Reinforcing spanning in the slab span shall remain. Clean and apply corrosion inhibitor. Verify bottom and top reinforcing's diameter has not been reduced by more that 10% o Clean and coat reinforcing spanning perpendicular to the slab span direction per detail 1/S300. Verify min 1/2 " diameter of competent steel remains. If less, provide #3 bars between each existing bar as shown in 2/S300 Typical slab replacement detail om sheet S300. o 1" cover around dowels, increase depth of removed concrete around dowels as required, typical. o Roughen all surfaces between new and existing concrete and apply bonding agent, typical. o Cut or mechanically remove concrete flush with beams as shown in detail 2/S300 on sheet S300. Do not cut existing slab reinforcing. o Verify all concrete at all beams below slab is competent. If not notify Engineer of Record. o Where compromised concrete thicker than 1 3/4 " does not extend past the face of the beam, cut or chip away slab flush with beam face as shown in detail 2/S300 on sheet S300. DO NOT CUT EXISTING REINFORCING. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document.
