How to Read a Commercial Paving Proposal: Line Items Property Managers Should Understand
OAKLAND, Calif. Three paving proposals land on your desk for the same parking lot. One is a single page with a lump sum. One is four pages of line items you don’t fully recognize. The third is somewhere in between, and the prices are tens of thousands of dollars apart. Which one is right?
The answer usually isn’t the lowest number or the highest. It is the proposal that clearly describes the work your lot actually needs. Knowing how to read the line items is the fastest way to tell a complete scope from one that will turn into change orders later.
Why Paving Proposals Look So Different
There is no standard format for a commercial paving proposal. Every contractor writes them their own way, and some are vague on purpose. Two bids can use the same words, like “resurface” or “repair,” and mean completely different things.
That is why the Contractors State License Board recommends comparing bids based on the same plans, specifications, and scope of work, and warns against automatically accepting the lowest bid. An unusually low price often means something important is missing.
The Line Items You Will See Most Often
Mobilization
This covers moving equipment and crews to your site. It is a real cost, especially for work that requires pavers, rollers, milling machines, and trucks. Mobilization should appear once per phase. If a project is split into several phases to keep the property open, expect it more than once.
Saw cutting and removal
For repairs, the proposal should say how damaged areas will be cut and removed, and roughly how many square feet are included. Look for language about removing asphalt and repairing base if needed. A proposal that only says “patch failed areas” without quantities leaves a lot of room for interpretation.
Base repair or subgrade work
This is one of the most important items and one of the most commonly left out. If the base under failed areas is soft or saturated, new asphalt placed over it will fail again. Good proposals either include a quantity of base repair or state a unit price for additional base work if it is discovered during excavation.
Milling
Asphalt milling grinds off the top layer of existing pavement so the new surface can be placed at the correct height. The proposal should state the depth, such as one and a half or two inches, and the area. Milling depth affects how thick the new asphalt will be, which directly affects how long it lasts.
Asphalt thickness and mix
Look for the compacted thickness of new asphalt, not just “pave.” Two inches and three inches of asphalt are very different products. If the proposal lists a mix type or specification, that is a good sign the contractor has thought through the traffic your lot carries.
Crack sealing
Crack sealing should specify the material, typically hot applied rubberized sealant, and whether cracks will be cleaned and routed first. Pricing is often by the linear foot or by the area of the lot.
Sealcoating
Sealcoating line items should state the product, the number of coats, and whether sand or aggregate is added for traction. Two coats are standard for most commercial lots. Our page on sealcoating explains what to expect.
Striping and markings
Restriping should list what is included: stalls, arrows, crosswalks, fire lanes, red curbs, ADA symbols, and stencils. If the layout is changing, the proposal should say so. Missing items here often turn into small change orders after the lot is sealed.
ADA items
If the project touches parking, walkways, or ramps, ADA compliance may be triggered. Look for specific items like accessible stall striping, signage, truncated domes, and slope corrections. Federal standards under the ADA set limits on changes in level and surface conditions along accessible routes, and California adds its own requirements on top. Our ADA upgrades page covers the most common items.
Traffic control and phasing
For occupied properties, the proposal should describe how work will be staged so tenants and customers can still get in. That might mean working in sections, after hours, or on weekends. Clear phasing protects your tenants and your schedule.
What Is Often Missing From a Low Bid
When one proposal is far below the others, compare it line by line. These are the items we see left out most often:
- Base repair under failed areas
- Specified asphalt thickness after compaction
- Restriping after sealcoating or paving
- ADA corrections triggered by the work
- Concrete repairs at curbs, gutters, and ramps
- Cleanup, sweeping, and haul off of removed material
None of these are optional on most projects. If they are not in the proposal, they will either show up later as change orders or not get done at all.
Red Flags Worth Paying Attention To
Most contractors write honest proposals, but a few warning signs come up often enough that they are worth knowing.
No quantities anywhere. If a proposal never mentions square footage, tonnage, or linear feet, you have no way to confirm what you are buying. It also makes it hard to hold anyone accountable when the work is done.
Vague repair language. Phrases like “repair as needed” or “patch where necessary” sound flexible, but they let the contractor decide how much work to do after the price is set. Ask for an estimated area and a unit price for anything beyond it.
Pressure to sign quickly. A limited time discount on a commercial paving project is unusual. Good contractors expect you to compare bids and take the proposal to ownership or the board.
Large deposits. Payment terms vary on commercial work, but a request for a big payment before any work starts deserves questions. Ask how payments line up with completed phases.
No license number. California requires contractors to show their license number on bids and contracts. Verify it with the CSLB before you sign.
Payment Terms and Schedule
Read the last page of the proposal as carefully as the first. Payment terms should be clear about when invoices are issued and what triggers each payment. Phased projects often bill by phase. The schedule section should give a realistic start window and duration, and explain what happens when rain or other conditions push the work back. If the proposal is silent on schedule, ask for it in writing before you commit.
Questions to Ask Before You Sign
- What happens if you find bad base during excavation, and how is it priced?
- What is the compacted thickness of the new asphalt?
- Is restriping included, and does it match the current layout?
- How will the work be phased to keep the property open?
- How are weather delays handled?
- What warranty is provided, and what does it cover?
A contractor who answers these clearly and in writing is usually one you can work with. Our guide on how to choose a commercial paving contractor covers licensing, insurance, and references in more detail.
Frequently Asked Questions
Should a paving proposal be lump sum or itemized?
Itemized is better. It lets you compare scope across contractors and adjust the project if the budget changes.
Why is mobilization charged separately?
Moving heavy equipment and crews to a site is a real cost. Listing it separately makes the rest of the pricing easier to compare.
What is a unit price in a paving proposal?
It is a price per square foot, ton, or linear foot for additional work, like extra base repair. It protects you from unpriced change orders.
How many proposals should I get?
Three is a common number. More important than the count is making sure each contractor is bidding the same scope.
