Repair a broken curb ramp on a steep Ciudad Bolívar sidewalk

Ciudad Bolívar's steep sidewalks already make walking hard for elders and wheelchair users, and a cracked or missing curb ramp turns an ordinary corner into a real obstacle. A simple patch-and-repair job restores safe, level access at the corner. This is straightforward public-space repair work. Standard: UN-Habitat accessible public-space guidance; SDG 11 (Sustainable Cities and Communities) Proof: Before and after photos of the repaired curb ramp Method (UN-Habitat accessible public-space guidance; SDG 11 (Sustainable Cities and Communities)): 1. Confirm the curb ramp is public infrastructure and assess the damage. 2. Clear loose debris and broken material from the ramp surface. 3. Patch the surface with quick-set repair material, working it level. 4. Let the patch cure before allowing foot traffic. 5. Photograph the repaired, level ramp and record the date. Done when: Before and after photos of the repaired curb ramp

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 240–600 minutes. Method of record: Curb ramp repair/retrofit to ADA + PROWAG R304 (slope, landing, detectable warning surface), under municipal right-of-way permit — trained crew with wet-cut dust controls; assess→repair→verify

Bring

• right-of-way permit + cones/barricades + pedestrian detour signage
• smart level / digital inclinometer + tape measure
• concrete tools + detectable warning surface (truncated dome) panel per city standard
• wet-cut saw with water feed (dust control)

Steps

1. 1. ASSESS: measure the existing ramp against PROWAG R304 (running slope ≤8.3%, cross-slope ≤2%, landing, flush transition, detectable warning) and photograph each failure; confirm permit + utility locates before cutting.
2. 2. Set up cones/barricades and a safe pedestrian detour outside the work zone.
3. 3. Remove the failed ramp section with wet-cut dust controls; form and place the corrected ramp geometry per the city standard drawing.
4. 4. Set the detectable warning surface (truncated domes) aligned and embedded per spec; finish transitions flush with the gutter.
5. 5. VERIFY: re-measure every R304 dimension with the smart level, photograph readings + before/after from matching vantage, water-test the gutter flow line, and close out the permit.

If it does not match the plan

• No permit or no utility locate -> STOP: do not cut.
• Cutting without water-fed dust control -> STOP (respirable silica).
• Geometry cannot meet R304 within the existing footprint -> document and route to the city's ADA transition-plan engineer instead of pouring a non-compliant ramp.

What counts as done

• Measured running slope ≤8.3% and cross-slope ≤2% with level photos
• Detectable warning surface installed per standard (alignment + embed photos)
• Flush gutter transition verified (no lip >1/4 inch; water flows along the gutter line)
• Before/after photos + permit close-out reference

Proof is measured against these, not judged by taste.
