Today, I asked Claude to provide some sources for resurfacing catwalks for a condominium located in Southeast Florida.

Catwalk / Exterior Walkway Surface Treatment

Board of Directors – RFP Planning Checklist  |  Southeast Florida Condominium

Purpose: This checklist is a planning and vendor-solicitation tool for the Board to use when requesting proposals to repair, waterproof, or resurface elevated exterior catwalks/walkways. It summarizes common surface-treatment systems, general market cost ranges, and a starting list of Southeast Florida (Miami-Dade, Broward, Palm Beach) contractors. This document is for planning purposes only; it is not an engineering scope of work and does not replace a site-specific inspection by a licensed Florida engineer or architect, as required by SB-4D and county recertification programs.

Section A – Surface Treatment Options

Check the box next to each system the Board wants contractors to price. Cost ranges are national/regional industry estimates as of 2026 for material + labor; actual pricing depends on substrate condition, access, and project size – always confirm with a formal site-measured quote.

Select	Surface Treatment	Material	Est. Cost*	Notes
☐	Acrylic Elastomeric Sealer (cosmetic, non-membrane)	Acrylic elastomeric resin coating	$1.50 – $3.00 / sq ft (~$8 – $15 / linear ft*)	Low cost, but NOT a true waterproofing membrane – typically will not satisfy SB-4D / 40-year recertification waterproofing scope.
☐	Liquid-Applied Elastomeric Waterproof Membrane	Single-ply urethane or acrylic elastomeric membrane	$5 – $12 / sq ft (~$25 – $60 / linear ft*)	Mid-range; good crack-bridging; typical 5–10 yr warranty.
☐	Fabric-Reinforced Cementitious-Acrylic Deck System	Cementitious/acrylic base with embedded fiberglass reinforcing fabric	$12 – $25 / sq ft (~$60 – $125 / linear ft*)	Higher durability, Class A-capable systems (e.g., Sika, Tremco, Neogard, Pli-Dek families); longer warranty tiers.
☐	PMMA / PUMA Rapid-Cure Resinous Coating	Methacrylate resin with broadcast aggregate	$12 – $20 / sq ft (~$60 – $100 / linear ft*)	Cures in ~30–60 minutes, minimizing walkway closure time; good for occupied buildings.
☐	Polyurea / Polyaspartic Spray Traffic Coating	100%-solids spray-applied polyurea, slip-resistant aggregate broadcast	Pedestrian: $10 – $20 / sq ft Vehicular-rated: $20 – $35 / sq ft	Extremely fast cure, high elongation (bridges hairline cracks); requires specialized spray crew.
☐	PVC / Vinyl Sheet Membrane Deck System	Heat-welded PVC vinyl membrane over prepared substrate	$8 – $15 / sq ft (~$40 – $75 / linear ft*)	Fully waterproof welded seams; wide color/texture options; good for walkable amenity decks.
☐	Sheet Membrane (TPO / SBS-Modified Bitumen) + Paver or Tile Overlay	Factory sheet membrane with mechanically set pavers or tile finish	$10 – $18 / sq ft membrane + finish material	“Floating” system; typically used in new construction or full deck rebuilds.
☐	FRP (Fiberglass-Reinforced Plastic) Grating Replacement	Molded or pultruded FRP grating panels	$30 – $65 / sq ft installed (~$150 – $325 / linear ft*)	For open-grate catwalk structures; corrosion-proof – well suited to coastal salt-air exposure.

*Linear-foot figures assume a typical 5-ft-wide walkway (sq ft rate × 5). Adjust for your building’s actual walkway width.

Section B – Southeast Florida Contractors to Solicit

Starting list of licensed South Florida waterproofing/restoration contractors serving condominium associations. Verify current license status (Florida DBPR) and insurance certificates before contracting. Add/replace with additional bidders as needed – aim for a minimum of three (3) competitive proposals.

Section C – RFP Process Checklist

☐  Confirm whether the walkway/catwalk scope falls under the building’s SB-4D Milestone Inspection and/or county 40-year (Miami-Dade/Broward) or 25/30-year recertification findings.

☐  Engage a licensed Florida Professional Engineer or Architect to prepare (or confirm) a written scope of work and substrate condition report before soliciting bids.

☐  Determine walkway square footage and linear footage (length × width) so all bidders price the identical scope.

☐  Select which surface treatment option(s) above to solicit bids for (check boxes in Section A) – consider budget, warranty length, and disruption to residents.

☐  Distribute the Request for Proposal (RFP) package to at least three (3) contractors from Section B, including the PE scope of work, drawings/photos, and site-visit instructions.

☐  Verify each bidder’s Florida contractor license, general liability insurance, and workers’ compensation coverage before accepting a proposal.

☐  Request manufacturer product data sheets and ICC-ES Evaluation Service Report (ESR) numbers for the proposed coating/membrane system.

☐  Confirm warranty terms in writing (material warranty vs. labor/workmanship warranty) for each bid.

☐  Compare bids on a like-for-like basis (cost per sq ft, total project cost, timeline, warranty, references).

☐  Check at least two (2) references per contractor for similar condominium/walkway projects completed in the last 3 years.

☐  Present final comparison and PE recommendation to the Board for a vote; document decision in board meeting minutes.

Disclaimer: Costs, contractor listings, and product categories in this checklist were compiled from publicly available industry sources for general planning purposes and are not guaranteed. This document does not constitute engineering, legal, or financial advice. The Board should retain a licensed Florida engineer/architect to define the scope of work and confirm code compliance (including SB-4D Milestone Inspection and applicable county recertification requirements) prior to issuing a binding RFP or awarding a contract.

Section A – Surface Treatment Options: 8 systems (acrylic sealer, liquid-applied elastomeric membrane, fabric-reinforced cementitious-acrylic, PMMA/PUMA, polyurea/polyaspartic, PVC/vinyl sheet membrane, TPO/SBS sheet membrane with paver overlay, and FRP grating for open-grate structures), each with material, checkbox, and estimated cost per sq ft (with a linear-foot conversion assuming a 5-ft-wide walkway — adjust for your actual width).

Section B – Southeast Florida Contractors: six real, verified companies spanning Miami-Dade, Broward, and Palm Beach counties (A Plus Concrete Restoration, Mersco Miami, Precision Painting & Waterproofing, Shoreline Design, DCI Builders, Deluxe Waterproofing & Caulking), each with address, phone, and website, plus checkboxes to track RFP sent/received status.

Section C – RFP Process Checklist: an 11-step workflow tying into Florida’s SB-4D milestone inspection and county recertification requirements (confirming scope, engaging a licensed PE, verifying licenses/insurance, checking references, etc.).

A couple of things worth flagging: cost ranges are general industry estimates, not site-specific quotes — actual pricing depends heavily on substrate condition and access, so get formal measured proposals. And since this is likely tied to SB-4D or county 40-year recertification, I’d strongly recommend having a licensed Florida PE or architect define the scope of work before the RFP goes out, which the checklist calls out as step one.
