How to Request a Materials Quote from Stone Depot Trading
What to include in a sand, gravel, limestone or fly ash quote request: material, gradation, volume in m³ or MT, delivery site, dates and hauling needs.
A quotation for bulk materials is only as good as the inquiry behind it. "How much is gravel?" cannot be answered honestly, because the price depends on the size, the source that has it in stock, the volume, the road to your site and when you need it. This guide lists exactly what to send, explains why each item matters, and shows how a quotation from Stone Depot Trading is put together.
Why a complete inquiry gets a better quotation
Stone Depot Trading does not publish a fixed price list, because material at source, hauling and documentation are separate cost lines that change with every request. A complete inquiry lets the request be matched to the right trade-partner source on the first pass; an incomplete one leads to a round of clarifying questions. If some details are not final, send what you know and mark the rest for discussion.
The seven things to send
| # | Item | Example |
|---|---|---|
| 1 | Material and intended use | Crushed gravel for structural concrete |
| 2 | Grade, size or specification | 19 mm (3/4") nominal, ASTM C33 Size No. 67 |
| 3 | Quantity and unit | 1,200 m³ loose, or 40 metric tonnes for fly ash |
| 4 | Delivery location | Barangay, municipality or city, landmark, map pin |
| 5 | Required dates and frequency | First delivery 15 October; 2 trips per day for 6 weeks |
| 6 | Hauling and unloading needs | 10-wheeler access confirmed; tipping area available |
| 7 | Documents your specification requires | Sieve analysis, delivery receipts, VAT invoice |
The examples are illustrative, not typical order sizes.
1. Material and intended use
Say what the material is for. "Sand for plastering" and "sand for a concrete slab" point to different products. "Limestone for base course" and "limestone for agricultural lime" are different sources entirely. Fly ash for structural concrete is specified by class under ASTM C618 and normally has to be backed by test data for the lot; fly ash for fill is not held to the same paperwork.
2. Grade, size or specification
Give the size in millimetres or inches and, wherever possible, the standard behind it:
- Gravel: nominal size (9.5, 12.5, 19, 25, 37.5 mm) and the standard, whether an ASTM C33 size number or the DPWH pay item named in the contract.
- Sand: use (concrete, masonry, plaster, bedding) and any fineness modulus or fines limit.
- Base course and subbase: the DPWH pay item and any CBR, plasticity or abrasion requirement it carries.
- Limestone: grading for aggregate uses, or chemistry (calcium carbonate content, magnesia, loss on ignition, fineness) for industrial and agricultural uses.
- Fly ash: ASTM C618 Class F or Class C, plus any project-specific limit such as maximum loss on ignition.
Local names such as "G1", "S1" or "3/4" are fine as a starting point, but they vary between yards; the millimetre size and the standard remove the guesswork. See gravel sizes explained and the companion guide on types of construction sand if you are not sure.
3. Quantity and unit
Give the total quantity and the unit, and say whether the volume is loose (as delivered) or compacted (as placed). This is where most misunderstandings begin, so it has its own section below.
4. Delivery location
Give the barangay and municipality or city, a landmark, and a map pin if you have one. "Koronadal" is a city of many barangays with very different road access. Add whether the site is on the national highway, a concrete barangay road or an unpaved farm road, and whether trucks must cross a bridge with a load limit.
5. Required dates and frequency
State the first delivery date, the total period and the delivery rhythm. A single delivery over two days and the same quantity spread over three weeks are priced and scheduled differently. Include site working hours and any local truck restrictions you know about.
6. Hauling and unloading needs
Say whether you need the material delivered or will pick it up at the source with your own trucks, and what truck size the site can accept. For fly ash, say whether you have a silo with a pneumatic fill line or need bagged material.
7. Documents your specification requires
List what your project or accounting requires: sieve analysis and other test results (for DPWH work, usually from a laboratory accredited by DPWH through its Bureau of Research and Standards), a certificate of analysis for fly ash, a chemical or calcium carbonate equivalent report for industrial or agricultural limestone, delivery receipts per trip (which the mining rules in DAO 2010-21 require for every transport of sand and gravel), official receipts and VAT invoices, or copies of source permits.
Listing a document is a request, not a guarantee that it exists. What a source can actually issue depends on the material, the source, the supplier, your project specification, the testing arrangement and the agreed order requirements; where a result your specification needs has never been run, testing has to be arranged, which costs money and takes time. Say which reports or tests your specification requires and Stone Depot Trading will ask the source and confirm what can be provided before you order.
Volume: cubic metres or metric tonnes?
Aggregates are usually quoted per cubic metre loose; fly ash and industrial limestone per metric tonne, weighed. Converting between the two needs a bulk density, and bulk density depends on the material, its moisture and how loosely it sits in the truck. The values below are planning assumptions, not measurements of any specific product; use a measured density for the actual material where the difference matters.
| Material (loose, as delivered) | Assumed bulk density for planning |
|---|---|
| Crushed gravel, 19 mm | about 1.5–1.7 t/m³ |
| Dry sand | about 1.4–1.6 t/m³ |
| Wet sand | up to about 1.8–1.9 t/m³ |
| Crushed limestone or base course, loose | about 1.5–1.7 t/m³ |
Worked example with assumed numbers: a slab needs 250 m³ of compacted base course. Loose material loses volume under the roller; using an assumed 25% allowance, order about 250 × 1.25 = 313 m³ loose, rounded to 320 m³ to allow for waste. At an assumed 1.6 t/m³ that is about 510 metric tonnes, which sets the number of truck trips. Take the compaction allowance from your engineer or a field trial, not from this example.
State which figure you are quoting, and if a weighbridge ticket or a truck-bed measurement will be used to check deliveries, say so.
Delivery site and access
Access decides whether a 10-wheeler can deliver a full load per trip or whether the load must move in smaller trucks. Before sending an inquiry, walk the last kilometre and note:
- Road width and surface, sharp turns and overhead lines.
- Bridges and culverts with posted load limits.
- Space to turn and tip; a dump truck needs room to raise its bed safely.
- Ground conditions in rain; a soft yard can strand a loaded truck.
The full checklist is in delivery and logistics in Region XII.
Dates, frequency and hauling arrangements
Bulk material moves in trips, and trips per day are limited by distance, loading time at source and unloading time at site. A realistic schedule is one your site can actually receive: a free unloading bay, a checker who is present, and space to stockpile. A flexible delivery window often helps the logistics. The guide on hauling cost factors in SOCCSKSARGEN shows how distance, payload and turnaround feed into the delivered cost.
How the quotation is built
The process, as described under how it works on the Stone Depot Trading website, has four steps:
- Send the requirement. Material, specification, quantity, site and schedule.
- Source matching. The request is checked against available trade-partner sources for that material and specification.
- Quotation and terms. Material details, price, logistics terms and the documents that source is able to provide are confirmed.
- Order coordination. Once accepted, the supply and delivery arrangements are coordinated with the parties involved.
The quotation reflects source availability at the time, the specification, the quantity, the delivery location and the schedule, and it carries a validity period because those inputs change. Submitting an inquiry starts a sourcing conversation; it does not create a binding order.

FAQ
Do you publish a price list?
No. Pricing depends on the material, specification, quantity, source availability, delivery location and schedule. Submit the requirement for a project-specific quotation.
Can I inquire before the specification is final?
Yes. Provide the known requirements and identify which items still need discussion.
Can test documents be requested?
Yes — include them in the inquiry. Whether they can actually be supplied is a separate question: it depends on the material, the source, the supplier, your project specification, the testing arrangement and the agreed order requirements. Stone Depot Trading asks the source and confirms what is available before you order.
Where can deliveries be arranged?
Stone Depot Trading is based in General Santos City and coordinates deliveries across Region XII through trade partner sources and haulers. Provide the delivery location and schedule so feasibility and applicable terms can be confirmed.
How long is a quotation valid?
Each quotation carries its own validity period, because source availability, fuel and schedules change. Ask for the validity date when the quotation is issued.
