How commercial paving costs are quoted
Most commercial paving proposals use one of three pricing formats. Knowing which one you are looking at is the first step to comparing them.
- Per square foot. The total price divided by the area. It is easy to compare, but it hides thickness, base work and extras.
- Per ton of asphalt placed. Material is priced by weight, with labor and equipment priced separately.
- Lump sum with alternates. One price for a defined scope, with optional items such as striping or extra repairs priced individually.
None of these is better than the others. What matters is that the scope behind the number is written down.
Asphalt cost per square foot: why one number misleads
People searching for asphalt prices per square foot usually want a single figure. The problem is that two lots with the same area can need very different work. A figure that includes new aggregate base and three inches of asphalt is not comparable to one that covers only a thin overlay.
Asking for a per-square-foot number without the scope is like asking the price of a building per square foot without saying what it is made of. Use the number as a way to compare bids, not as a budget on its own.
Pavement installation cost: three kinds of projects
Most commercial paving falls into one of three types, each with a different cost profile.
Mill and overlay
The worn top layer is milled off and new asphalt is placed on the existing base. When the base is sound, this is usually the lowest-cost structural option. See our page on mill and overlay for when it works.
Full-depth replacement
The existing pavement, and sometimes part of the base, is removed and rebuilt. It costs more because more material and labor are involved, and it is the right answer when the base has failed.
New construction
A new site, or a large expansion, includes grading, base and asphalt, and often drainage and utility work. These projects are priced to the specific site.
What drives paving costs
These factors move the price of a commercial paving project the most:
- Area and phasing. Larger lots spread fixed costs further, but phasing to keep tenants open adds mobilizations.
- Asphalt thickness. Truck lanes and loading areas need more than car stalls.
- Base condition and depth. Failed or wet base has to be removed and replaced.
- Existing pavement. Removal and haul-off are real costs.
- Drainage and grade. Correcting slopes, and tying into curbs and gutters, takes work.
- Access and schedule. Night work, tight sites and tenant coordination affect labor.
- Material prices. Asphalt and aggregate prices change with oil and construction demand.
- Striping and ADA work. A finished lot needs a layout, accessible stalls and fire lane markings.
What is often not included
Ask whether each of these is in the price, because they are common sources of surprise:
- Striping and pavement markings
- Utility adjustments such as manholes and valve covers
- Concrete work, including curb, gutter and accessible ramps
- Traffic control and signage
- Permits, engineering and testing, where they are required
- Repairs to irrigation or landscaping disturbed by the work
How to compare paving bids
Put each bid next to the others and check these items, in this order:
- Same scope. Same areas, same thickness, same base work.
- Who performs the work. Contractors often use subcontractors for parts of a job. Ask who does what.
- Inclusions and exclusions. Use the list above.
- Schedule and phasing. How long, in what order, and what is closed when.
- Warranty. What is covered, for how long, and what voids it.
- Price validity and payment terms.
- License and insurance. Ask every bidder for an Arizona contractor license number and a certificate of insurance, and verify the license with the Arizona Registrar of Contractors.
Paving costs in Phoenix conditions
Phoenix heat and sun affect both cost and timing. High pavement temperatures influence mix and thickness in turning areas and at dumpsters. Monsoon drainage decides whether grade work is part of the job. And summer scheduling, including after-hours work to keep businesses open, can change labor cost. Our asphalt paving page covers these in more detail.
Maintenance changes the cost over time
The cheapest paving decision is usually not the lowest bid, it is keeping pavement from failing early. Sealcoating, crack sealing and repair cost a fraction of replacement, and they push replacement further away. A good paving bid should come with a maintenance plan.
