Expect a typical local bulk aggregate delivery to take a few business days once spec and quantity are confirmed, though peak season, specialty stone, or remote sites can extend the lead time to multiple weeks or more. The three fastest levers you control are confirming the material spec and quantity up front, confirming source yard availability, and clearing site access before the truck is dispatched.
TL;DR:
Standard dump trucks typically carry 10 to 16 tons, so convert volume using the yard’s density figures and schedule sequential loads by cycle time.
Dispatchers often give 30 to 60 minutes’ notice, so keep a site contact reachable with gate codes, turning details, and a clear dump point.
Check each load’s ticket, quantity, and material on arrival, then document any mismatch before the truck leaves; later acceptance makes disputes harder to resolve.
Recently delivered aggregate may need a day or more to drain before some concrete uses, so check moisture before scheduling placement.

O’Leary Development Group delivers bulk materials across San Antonio and surrounding cities for construction, landscaping, and industrial projects.
Typical lead times and seasonality: what to expect and why
Most local deliveries of common aggregates move fast once an order is placed, because yards keep standard materials like road base and sand in ready stockpile. Specialty stone, large tonnage, or orders placed during spring and summer construction surges behave differently, since every contractor in the region is competing for the same trucks and the same quarry output.
Distance to source matters too. A yard pulling material from a quarry 40 miles out adds haul time that a closer pit does not carry, and that gap compounds when several loads are needed in sequence rather than one drop.
Standard materials with local stock: often same-day to a few business days out.
Specialty stone, custom blends, or large tonnage: commonly one to three weeks, sometimes longer in peak season.
Multi-load projects: add cycle time per truck rather than assuming parallel delivery.
For a driveway or small landscaping job, a short window is realistic. For a site fill requiring dozens of loads, plan the schedule around production cadence at the yard, not just the date you want the material.
How to calculate quantity, truck counts, and order timing
Getting the math right before you call for a quote is what keeps a delivery on schedule instead of becoming a renegotiation. Start with spec and density, since yards to tons conversion varies by material (gravel runs heavier than mulch, for instance), and an under-ordered load means a second dispatch you did not plan for.
Confirm the spec (material type, size, moisture condition) and convert your cubic yard requirement to tons using the yard’s density figures.
Pick a realistic truck payload, typically 10 to 16 tons for a standard dump truck, and divide total tonnage by payload to get load count.
Estimate cycle time per truck: load-out at the yard, drive time to site, and dump and departure, then multiply by load count if trucks run sequentially rather than in a rotating queue.
Add a margin for staging limits, spillage, and handling loss, especially on tight urban sites.
Pro Tip:Ask the yard for their truck’s rated payload in tons, not cubic yards; converting density yourself after the fact is where most order-quantity errors start.
A quick example: a driveway needing 20 tons of road base fits in two loads on a 10-ton truck. A site fill needing 300 tons of fill dirt needs roughly 20 to 30 loads depending on truck size, which changes your schedule from an afternoon to a multi-day dispatch window. Our load count math and calendar guidance walks through this in more detail for multi-truck jobs.
Site-prep and access checklist before the truck arrives
A truck that cannot get in or dump cleanly turns a scheduled delivery into a delay, and most of those delays are preventable with a walkthrough the day before.

Confirm the access path, turning radius, and any weight-limited routes or low bridges along the approach.
Measure the staging area for footprint and overhead clearance, and arrange traffic control if the drop point sits near active roadwork or public access.
Plan the stockpile footprint with drainage in mind, and have temporary protection ready if rain is forecast.
Reconfirm 24 to 48 hours before delivery, and designate one person on site who can take the dispatch call.
Delivery day: what to expect, communication, and proof of delivery
Most dispatchers call or text a window rather than a fixed minute, often 30 to 60 minutes ahead, so someone on site needs to be reachable. The driver typically needs a gate code, a clear dump point, and a contact name, not a full site tour.
Expect a pre-delivery call or text with an estimated time of arrival rather than a guaranteed slot.
Have site contact information and access instructions ready before the truck leaves the yard.
Collect the ticket (paper or electronic), proof-of-delivery photos, and a sign-off confirming quantity and material match the order.
If a load looks off-spec or short, document it immediately and flag it before the truck leaves, since acceptance after departure makes disputes harder to resolve.
Delays rarely come from one cause. They stack: a quarry running behind on a specialty blend, a storm closing a haul route, and a driver running out of available hours on the same week.
Specialty materials can carry genuine long-lead realities at the quarry level, independent of how fast the hauler can move once material is ready.
Weather and seasonal surge often justify a buffer multiplier of one and a half to two times your normal lead-time estimate during peak months.
FMCSA hours-of-service rules limit drivers to an 11-hour driving window after a qualifying rest period, which caps how many loads a single truck and driver can run in a day, a real constraint on multi-load schedules.
Staging constraints on tight urban sites can slow dump-and-turn time enough to reduce daily load throughput.
Pro Tip:Keep a backup yard’s contact on file; when your primary source hits a production bottleneck, a second quote in hand saves days compared to starting a new search from scratch.
Tactical mitigations include staging delivery across multiple days instead of one large push, using conditional notice-to-proceed language tied to confirmed material availability, and keeping an escalation contact at the yard for day-of issues.
Material handling after delivery: stockpile management, moisture, and QC
What happens after the truck leaves affects whether the material is usable on schedule or needs to sit. Keep stockpiles of different materials separated and graded for drainage, since mixing or ponding invites contamination that shows up later in testing.
Separate stockpiles by material type and avoid dropping from excessive height, which causes segregation.
Grade the pad for drainage so standing water does not saturate the base of the pile.
Pull a quick moisture check and a visual sieve check on arrival, and document both for acceptance records.
Hold or blend on site if moisture or gradation looks off rather than placing material that will not perform.
Industry guidance notes that recently delivered aggregate may need a day or more to drain before use in some concrete applications, a detail worth building into your schedule rather than discovering on pour day, according to Iowa State aggregate moisture guidance.
Planning and contract schedule implications: buffers and documentation
Treating a delivery as just another phone call is how schedules slip. The the FHWA’s guide to contract time determination recommends building contract time from project-specific factors, material availability, haul distance, quantity, truck capacity, staging, and weather, rather than relying on a single generic lead-time number.
List delivery as a scheduled activity in your CPM schedule with its own predecessors, not a buried line item inside “site work.”
Size your buffer from the mitigation factors above: tighter for standard material with local stock, wider for specialty stone or peak season.
Use conditional notice-to-proceed or completion-date language when a controlling material has not yet been confirmed available.
Keep dispatch confirmations, tickets, and reconfirmation notes on file, since documented material delays outside your control are what support a time-extension claim.
FHWA’s stockpile guidance also matters for progress payments: stockpiled materials must meet spec, be paid for, and be secured properly, and premature stockpiling for Federal participation is restricted.
Visibility tools: e-Ticketing and digital workflows
FHWA’s Every Day Counts program describes e-Ticketing as a way to record and transmit material type, quantity, and delivery information in real time from plant to site, cutting the administrative time usually spent chasing paper weight tickets.
E-Ticketing speeds reconciliation but does not add quarry or haul capacity; it is a coordination tool, not a production fix.
Rollout commonly runs into cellular coverage gaps, driver training gaps, and unclear reconciliation responsibilities between yard and site.
Keep a paper-ticket fallback ready for sites with weak connectivity.
Specify e-Ticketing format and acceptance requirements directly in the purchase order so expectations are set before the first load moves.
How O’Leary Development Group executes reliable delivery
Our scheduling approach for Greater San Antonio contractors follows the same logic outlined above: confirm spec and quantity first, confirm yard availability, then lock site access details before dispatch.

Balancing cost and schedule risk
Buffer time scales with how little margin your schedule has. On a tight critical path, pay for the faster, more reliable option; on a flexible schedule, a longer lead time at a lower cost is a reasonable trade. The clearest way to present delivery risk to stakeholders is a single sentence: here is the lead time, here is the buffer, here is what happens if it slips.

FAQ
What is the standard lead time for delivery?
There is no single universal number; lead time depends on material availability, quantity, haul distance, and site access, as FHWA’s contract time guidance notes. In practice, standard materials with local stock often move in a few business days, while specialty orders or peak-season demand can stretch to several weeks.
How long does it take for a gravel driveway to settle?
Settling time depends on material compaction, moisture, and traffic use rather than a fixed calendar count. Keeping the stockpile properly drained before spreading, as covered in our stockpile handling section, reduces the risk of uneven settling later.
How much is 5 yards of gravel delivered?
Pricing depends on material type, distance, and load size, and is best confirmed with a direct quote rather than a general estimate. Our demolition haul-off and per-load pricing page lists current per-load pricing you can check against your project.
What is the typical lead time for material delivery?
For common materials with local stock, a few business days is typical once spec and quantity are confirmed. Specialty stone, large tonnage requiring multiple trucks, or peak-season demand can extend that to one to three weeks, which is why confirming yard availability early matters more than the order date itself.
