Commercial Sidewalk Trip Hazard Repair Cost Calculator

With the defaults the job comes to $11,290. Grinding the lower band is $3,300 (37.5 inch-feet) and the upper band $2,800 (20 inch-feet), panel replacement is $2,250, saw cutting is $400, the curb ramp is $640, the 2 detectable warning pads are $550, pedestrian control is $600 and mobilization is $750. That is $376.33 per repair location, counting the 24 hazards and 6 panels as 30 locations.

Inch-feet are the offset in inches times the length in feet. The calculator takes the middle of each band as the offset (0.375 in and 1.25 in), which is an estimate: the Federal Way tab below prices “Inch Feet” without saying how the city measures one. A 3/8 in offset along 5 ft is 1.875 inch-feet, or $165 at $88. A 4 ft hazard in the upper band is 5 inch-feet, or $700 at $140. A 5 x 5 ft panel is $375, or $455 with 20 LF of saw cutting. So at the default prices, grinding one 4 ft upper-band hazard costs more than replacing a 5 x 5 ft panel, while a 5 ft lower-band hazard costs less; measure your own hazards rather than relying on the band alone.

Pedestrian control is $600, so turning it off takes the default job to $10,690. Saw cutting is its own input and is not worked out from the panels, so enter the length you expect to cut: at the defaults, cutting 120 LF around 6 panels with no grinding, ramp or pads, and no pedestrian control, adds up to $3,480.

The $1,500 minimum is a floor that sets the price only when the job adds up to less. One 5 ft hazard in the lower band with the $750 mobilization adds up to $915, so the minimum sets the price at $1,500. With every quantity at zero and pedestrian control on, the lines add up to $1,350 and the total is the $1,500 minimum. Mobilization is a charge on every job.

The City of Federal Way (Washington) tabulated three bids (bid review May 8, 2025) for RFB 25-004, a concrete sidewalk beveling on-call contract, with estimated quantities of 300 inch-feet of repairs from 1/4 to 1/2 in and 200 inch-feet from 1/2 to 2 in. The lower band was $61.95 (Precision Concrete Cutting, the lowest bid), $88.00 (BP Construction LLC) and $150.00 (Goldrock Invt LLC) per inch-foot; the upper band was $61.95, $140.00 and $250.00. Each bid also had a $100 lump-sum item, “Re-Mobilization for Small Quantities”. The totals printed on the tab were $31,075, $54,500 and $95,000; the highest is $100 less than the sum of its three printed items, and the tab does not say why. The tab marks no bid as flagged.

At the same 300 and 200 inch-feet as Federal Way’s estimate and no mobilization, the calculator’s grinding lines come to $54,400 at its default prices, $30,975 at the low bid’s $61.95 in both bands and $95,000 at $150 and $250. The defaults are BP Construction’s unit prices, so the $54,400 matches that bid’s two grinding items by construction; it is not an independent check. The calculator adds a $750 mobilization in place of the $100 item, and Federal Way’s is an on-call contract.

The City of Union (Kentucky) file titled “2025 Concrete Bids” (its web address is in the city’s March 2025 uploads) has six bidders, and the sheet shows no bid date. For 400 SF of its remove-and-replace 4 in concrete item the six totals ran from $4,800 to $7,200 ($12 to $18 per SF), and the lowest total bid on the sheet was Hendy’s at $32,795. The sheet marks no bid as flagged. The calculator’s 16 panels of 5 x 5 ft (400 sq ft) at $15 is $6,000. For 800 SF of “Typical Curb Ramp” the totals ran from $10,000 to $40,000 ($12.50 to $50 per SF), against $12,800 at the calculator’s $16, and detectable warnings were a separate item. For 8 “ADA Detectable Truncated Domes” (EA) the totals ran from $1,920 ($240) to $4,000 ($500), against $2,200 at $275. The tab does not say what size an each is, or whether the panel price includes saw cutting, which the calculator prices separately at $4 per LF.

The City of Happy Valley (Oregon) 2025 Sidewalk Maintenance Project (CIP-06-25) had nine bidders, and the lowest total bid was TTE, Inc. at $279,925; the highest was $820,825. Its “Saw Cut AC & Concrete” item, 5,000 LF, was $2.00 to $7.50 per LF, and TTE’s was $4.00, which is the calculator’s default. Its item for 4-inch concrete sidewalk, including 2-inch leveling course rock, 400 SY, was $140 to $245 per SY, or $15.56 to $27.22 per SF, and TTE’s was $180 per SY, $20.00 per SF. Excavation (“Common Excavation for Sidewalks, Driveways and Asphalt”, 675 CY, $43 to $175 per CY) and the saw cut above are separate items on the tab, with their own prices. The per-SF figure is for the item as the tab names it, so it is not a like-for-like price for the calculator’s panel line, and the calculator’s $15 per sq ft is about $0.56 below the lowest of the nine. It also bid traffic control and pedestrian protection as a lump sum of $25,000 to $200,000 on a project of $279,925 to $820,825, so it gives no price for the calculator’s $600 pedestrian control, which is an estimate.

Treat these as reference points, not as our prices. They are municipal-volume bids from 2025 tabs and Union’s undated 2025 file, the scope and quantities differ, and a small private job usually prices higher. The calculator carries that as the $750 mobilization and the $1,500 minimum job, and in three unit-price choices that are estimates, not figures from any bid tab: grinding at the middle Federal Way bid, 42% above the low bid in the lower band and 126% above it in the upper band; panel replacement at $15, above the median of $13.50 and the low of $12 of Union’s six bids; and pads at $275, above the median of $262.50 and the low of $240. The curb ramp default of $16 is below the median of $18 of Union’s six bids.

The 2010 ADA Standards for Accessible Design, section 303 “Changes in Level”, as published on ADA.gov, say: 303.2 Vertical. “Changes in level of 1/4 inch (6.4 mm) high maximum shall be permitted to be vertical.” 303.3 Beveled. “Changes in level between 1/4 inch (6.4 mm) high minimum and 1/2 inch (13 mm) high maximum shall be beveled with a slope not steeper than 1:2.” 303.4 Ramps. “Changes in level greater than 1/2 inch (13 mm) high shall be ramped, and shall comply with 405 or 406.”

The calculator’s two bands follow Federal Way’s two bid items, which are 1/4 to 1/2 in and 1/2 to 2 in; they are not an ADA reading of which repair is allowed. Section 303 is about changes in level, and the calculator cannot tell you whether a particular repair meets it. Offsets over 2 in are outside the grinding bands: count those panels under panels to replace. Polyurethane foam lifting and mudjacking are other ways to correct a settled panel; the calculator does not price them, because there is no public bid source for them here.

The ADA.gov page says the 2010 Standards set minimum requirements for newly designed and constructed or altered State and local government facilities, public accommodations and commercial facilities. It says adopting them also establishes a revised reference point for Title II entities that choose to make structural changes to existing facilities to meet their program accessibility requirements, and a similar reference for Title III entities undertaking readily achievable barrier removal. This page does not say that the ADA requires an owner to repair a particular sidewalk by a particular date; whether and when work is needed depends on the facts of your property, and an accessibility consultant or attorney can advise you.

Panel replacement is priced per square foot from the number of panels and their length and width, 5 x 5 ft by default. Six panels of 4 x 4 ft instead of 5 x 5 ft take the default job from $11,290 to $10,480. Saw cutting is a separate input in linear feet, and the curb ramp is priced per square foot of ramp with the detectable warning pads as their own item, as on the Union sheet.

ADA 705.1 says: “Detectable warnings shall consist of a surface of truncated domes and shall comply with 705.” That describes what a detectable warning is made of; this page does not say where one is required. The calculator counts each pad as one unit at $275, so use the number your contractor will install, and match the price to its size.

The calculator prices the repair items above and nothing else: not curbs, excavation or base, tree roots, drainage, permits, engineering, lighting, or restoring grass and landscaping. Add anything else as a bid-mode extra.
