Site work for a water / sewer project in Yale, British Columbia. Completed plans call for site work for a water / sewer project.

The Fraser Valley Regional District is seeking proposals from qualified proponents in response to this request for proposals for the provision of preventative concrete repair work on the reinforced concrete water reservoir tank located at 65225 Albert Street in Yale, BC. The project will encompass a comprehensive scope of work, including concrete assessment, exterior and interior crack and joint repair, exterior surface treatment and repair, application of an interior waterproofing system, and other necessary tasks essential for the refurbishment of the exterior and interior concrete surfaces of the water reservoir tank. The primary objective is to extend the lifespan of the tank, ensuring its continued functionality and safety for the future. The FVRD anticipates the services will include, but are not limited to: Interior and Exterior Joint/Crack Injection Repair: (i) Clean and prepare all identified joints and cracks; (ii) Remove and clean efflorescence around affected areas; (iii) Remove and clean all contamination from cracks by vacuuming or flushing with water or other effective cleaning solution; (iv) Remove any existing joint filler, caulk, or sealant within cracks; (v) Remove all contaminates including dust, debris, and other foreign particles to make ready for sealant; (vi) Structural Engineer to review and approve prepare joints and cracks before application of crack injection; (vii) Contractor to seal all joints and cracks with an approved NSF 61 polyurethane product such as SikaFix LV or approved alternative; (viii) Mix and install NSF 61 certified polyurethane chemical grout in accordance with manufacturer's recommendation and methods; (ix)Contractor to tool joints to assure neat joints, correct bead shape, and optimal adhesion. Concrete Delamination Repair (x) Ensure that the conditioned surface of the delaminated areas is free of material that may inhibit bonding with the concrete patch material; (xi) Remove loose, delaminated or unsound concrete by use of high pressure water blast, chipping, or other effective means; (xii) Remove and clean efflorescence around affected areas; (xiii) Complete structural or reinforcing steel corrosion repairs as necessary; (xiv) Exposed reinforcing steel shall be mechanically cleaned to bare metal and cleaned to remove all loose and fractured concrete. Exposed steel in areas to be patched shall be painted with bonding agent; (xv) Repair all exterior delaminate concrete. Contractor to chip or saw cut identified areas in a square/ symmetrical pattern in accordance with best management practices; (xvi) Structural Engineer to inspect exposed rebar and prepared area for approval prior to patch installation; (xvii) Apply bonding agent before patching grout in accordance with manufacture's recommendation and methods and as required; (xviii) Install concrete repair mortar such as Xypex Megamix II or approved alternative in accordance with the manufacture's recommendations and methods; (xix) Concrete patches are to be troweled and broom finished to the same level as the existing concrete to provide a professional and neat repair; (xx) Place the patching concrete by an approved method and consolidate using a pencil vibrator as required; (xxi) Finish of repair shall be troweled to match the existing condition. Curing of repair as specified in accordance with the manufacturer's recommendation and methods. (xxii) Protect repaired surface during cure time from rain, wind, snow, and rapid evaporation. Crystalline Waterproofing Concrete Repair: (xxiii) Concrete surface to be cleaned and free of any dirt, debris, film, paint, coatings and other foreign matter; (xxiv) Prepare surfaces using the methods recommended by the manufacturer to achieve best results; (xxv) Contractor to use sand blasting, water blasting or acid etching as required and recommended by the manufacturer; (xxvi) Contract to patch water leaks, holes, construction joints, and cracks prior to application; (xxvii) Contractor to remove all defective concrete; (xxviii) Surface to be brought to a saturated surface dry (SSD) condition as per manufacturer application recommendations before application; (xxix) Apply a crystalline waterproofing slurry system, such as Krystol T1 or approved alternative, over the entire interior tank wall as per manufacturer's recommendation and methods. Product to be safe for contact with potable water and certified by NSF 61; (xxx) Apply slurry using a brush or spray in two (2) coats using the application coverage specified by the manufacturer. Second coat to be applied after first coat has set and is to follow the application instructions of the manufacturer; (xxxi) Protect applied product during cure time from rain, frost, and early drying; (xxxii) Curing method to be sufficient for application inside a water reservoir tank.
