Site work for a municipal facility in Des Moines, Iowa. Completed plans call for site work for a municipal facility.

NEW WORK: Replace the bottom portion of damaged panels only, re-grade for proper drainage away from building and provide new pavement and sidewalk hardscapes directly adjacent to building necessary for repairs. NORTH ADDITION : Replace approximately 31% (2,240 SF of 7,319 SF) of bottom portion of the outer architectural veneer wythe from the panels lowest control joint to the foundation/footing below, see Drawing Sheet A201. West wall - approximately 9.7% (405 of 4,172 SF). North wall - approximately 7.9% (91 of 1,147 SF). O East wall - approximately 87.2% (1,744 of 2,000 SF). O This will require removal of adjacent hardscapes and excavation to top of foundation/footing. Replacement panels shall match the exposed aggregate finish as close as possible and will be inspected and approved before installation. Structurally attach new panels to the interior structural wythe. Replace damaged and missing rigid insulation at center wythe. Backfill low spots for adequate coverage over foundation and re-grade at perimeter of addition for proper drainage away from building. Remove two (2) stairway platforms at exterior doors for panel replacement. Reinstall with independent supports and footings not attached to building façade. Replace and re-slope approximately 660 square feet of pavement hardscape at low spots and promote positive drainage away from building. Provide pavement expansion joints as required. Replace approximately 980 square feet of sidewalk with proper slope away from building with continuous expansion joint and sealant between hardscape and building intersection. Do not "key" sidewalk into pavement system, this should be a slip joint to allow for pavement expansion. Repair parapet flashing cap and reseal. Trim/cut-back overgrown vegetation and foliage to avoid contact with building. Patch holes and gaps to match existing at remaining panels and foundation. Pressure wash entire façade, prepare spalls and cracks for new concrete sealer application. Remove approximately 3,143 linear feet (LF) of panel joint sealant at perimeter of addition, prepare joints for application of new panel joint sealant. Sealant shall be industry-used, rapid-setting, epoxy-based bonding adhesive designed for use to strengthen concrete substrates. Remove sealant at penetrations and openings, prepare surfaces for application of new sealant. Prior to next design phase, conduct invasive/destructive investigation of select bottom panel sections to determine the extent of bowing of the veneer wythe and structural integrity of attachment to the structural wythe of the precast wall assembly. This scope is currently not included in the work order and is unknown to the extent of additional design and construction costs. EAST ADDITION: Replace bottom portion of the outer architectural veneer wythe from bottom of the brick to the foundation/footing below, see Drawing Sheet A202. North wall - approximately 24.2% (124 of 511 SF). This will require removal of adjacent hardscapes and excavation to top of foundation/footing. Replacement panels shall match the exposed aggregate finish as close as possible and will be inspected and approved before installation. Structurally attach new panels to the interior structural wythe. o Replace damaged and missing rigid insulation at center wythe. Replace and re-slope approximately 260 SF of pavement hardscape at low spots and to promote positive drainage away from building with continuous expansion joint and sealant between hardscape and building intersection. Provide pavement expansion joints as required. Remove and replace approximately 20 LF of brick wall to service door, match existing. Patch holes and gaps to match existing at remaining panels and foundation. Pressure wash entire façade, prepare spalls and cracks for new concrete sealer application, including horizontal surface at dock canopy parapet. Remove approximately 1,082 linear feet (LF) of panel joint sealant at perimeter of addition dock canopy parapet (including horizontal surface) and upper wall above dock roof, prepare joints for application of new panel joint sealant. Sealant shall be industry-used, rapid-setting, epoxy-based bonding adhesive designed for use to strengthen concrete substrates. Remove sealant at penetrations and openings, prepare surfaces for application of new sealant.
