Before a Stone Quote: Drawings, Area & Schedule Prep
When a stone quote request only says "roughly how much would this cost?", the answer can only be rough in return. When drawings, area, thickness, finish, fabrication scope, and schedule are missing, suppliers pad the number with risk buffer, and buyers feel like the figures keep shifting. Slow quotes are often not about material shortages — they are about missing information.
On the ground, the same questions repeat: "We sent a PDF — why are they asking again?", "We only have area — how do we set the waste rate?", "The schedule is tight — should we ask about slab or cut-to-size?" An early budget range and a firm order-ready quote need different inputs. If the stage isn't stated, both sides end up comparing numbers from different levels of certainty.
This guide covers how organizing drawings, area, and schedule before you request a quote speeds up the conversation — what to put in an RFQ, a practical sense of waste rates, and the difference between slab and cut-to-size requests. Browse material tones in Products and see them applied in Projects. For checks right after delivery, see the slab delivery checklist.
Even just the use case, an approximate area, and a target schedule are enough for Contact to narrow down direction. If you already have drawings or a size list, quote, block, and slab-supply consultations get more accurate.
First things to know: a quote is defined by "scope," not "material name"
Marble, granite, and onyx are all "natural stone," but their pricing logic differs. Whether it's slab stock sold as-is, cut-to-size fabrication, or work that involves edges, sink cutouts, bookmatching, or dry-lay changes the factory process and lead time entirely. International stone RFQ guidance consistently recommends stating material type, application, size, thickness, finish, drawings, packing, destination, trade terms, and project stage together.
That's why "Carrara White for the lobby" alone isn't enough. If floor vs. wall, polished vs. honed, 2cm vs. 3cm, and tile module vs. large-format slab are left out, the quote gets filled in with assumptions. For spaces with complex specs like hotel lobbies, the hotel and commercial lobby spec guide lists what to put on paper first, which pairs well with quote prep.
1. State the project stage up front
Quote requests generally fall into three layers: (1) early budgeting (candidate materials, rough area), (2) bid comparison (drawings, finish, and thickness mostly fixed), (3) order-ready (approved samples, size list, delivery date). Even one line noting which stage you're at keeps a "wide-range estimate" from being confused with a "near-final unit price."
At the early budgeting stage, you don't need a perfect CAD file. Use case, approximate m², preferred tone, slab or tile preference, and a target install month are enough to get candidates and a rough price band. On the other hand, if you're order-ready but only have a PDF sketch, factory nesting and edge work stay uncertain, so the buffer grows.
For comparison quotes, sending the same information package to multiple suppliers is what makes the numbers comparable. If one supplier gets a DWG file and edge spec while another only gets "about 120 m²," the lower number isn't necessarily the better deal.
2. Drawings and size lists: what's actually needed
For cut-to-size pieces, countertops, stairs, wall panels, and complex openings, drawings are the backbone of the quote. The industry generally notes that vector CAD (DWG/DXF) is far more useful for nesting and area takeoff than a static PDF, which often requires re-measuring and leads to more back-and-forth and error. Floor plans, elevations, sections, a room schedule, and joint/edge/cutout locations make the fabrication scope clear.
If shop drawings don't exist yet, sharing architectural or interior drawings, marked-up layouts, or even a BOQ is still worthwhile. The usual flow is for the supplier to produce stone shop drawings for approval, and cutting before approval tends to make later corrections expensive. Simple slab or standard tile inquiries, on the other hand, can often be quoted from size, piece count, thickness, finish, and destination alone.
Edge profiles (eased, mitered, bullnose, etc.), sink/cooktop/faucet holes, skirting, waterjet patterns, and bookmatch/numbering/dry-lay requirements should all be spelled out as "special fabrication." Vague phrases like "polish if needed" tend to get interpreted differently by different fabricators, which changes process time.
3. Separate net area from order area
Net area is the measured surface to be covered — openings and built-ins excluded, with a single unit (m² or ft²). Order area adds cutting loss, breakage, defect avoidance, and future repair stock ("attic stock") on top of that. Guidance commonly suggests roughly 5–10% for simple straight installs, around 10% for typical residential work, 12–15% for diagonal or complex patterns, and 15–25% for bookmatch, waterjet, or exotic stone. Every project differs, so it's safer to agree on a rate together with layout complexity in mind rather than fixing "our site is X%" as a hard number.
For slab orders, area alone can be insufficient. Available slab dimensions, lot continuity, and bundle sizing all affect the actual piece count you'll get. Lots and bookmatching are covered in more depth in the lot, bundle, and bookmatch guide — and at the quote stage, it helps to state up front whether "same lot required" applies.
Splitting the area table by zone (lobby floor / elevator lobby wall / countertop) keeps items with different thickness or finish from being mixed into one line. A table with area per zone and preferred finish speeds up the quote reply.
4. Schedule isn't just "install date"
The natural-stone lead-time path runs sample approval → stock allocation or block cutting → fabrication and inspection → packing → shipping → site receiving → (if needed) dry-lay approval → installation. If you only write "install in March," the supplier has to guess at everything upstream of that. Noting the sample deadline, approval window, target ship/receive dates, and whether staged delivery is needed lets both sides build a realistic schedule together.
Under a tight schedule, in-stock slabs, standard thicknesses, and simple finishes work in your favor; special blocks and large bookmatched areas need more room. If schedule and quality (lot consistency, dry-lay) conflict, write down the priority — "both at maximum" is hard to price into a quote.
When overseas supply or container shipping is involved, shipping and customs buffers matter too. Including destination (port, warehouse, or site), preferred trade terms (if applicable), and packing/document requirements in the RFQ cuts down on follow-up questions.
5. A one-page RFQ checklist to send in
Check the items below and send them to Contact — quote, block, and slab-supply consultations can then move forward all at once.
- Item — Example
- Stage — Early budget / bid comparison / order-ready
- Use & space — Hotel lobby floor, kitchen island
- Material candidates — Marble / granite / undecided, preferred tone
- Area — Net area ~120 m², table by zone
- Thickness & finish — 2cm polished, honed at entrance only
- Drawings & list — DWG or size list, edges & cutouts
- Special requirements — Bookmatch, same lot, dry-lay
- Schedule — Target dates for sample, approval, receipt, install
- Delivery — Site / warehouse, staged delivery or not
Photos, reference links, and an approved sample code are a bonus. Even with partial information, we can start with a preliminary quote that clearly states its assumptions.
6. Common preparation mistakes and consulting with MarbleBest
Common mistakes include: (1) sending only a material name with no use case or area, (2) expecting a firm cut-to-size quote from a PDF alone, (3) setting waste at 0% and then claiming a shortfall, (4) giving only an install date while ignoring approval and production lead time, and (5) comparing unit prices across suppliers who were each given different information. On the other hand, sending drawings, an area table, and a schedule as one package lets stock checks and fabrication scoping happen in parallel.
MarbleBest handles marble and granite quotes together with block and slab supply consulting. Check material tones in Products and similar spaces in Projects, then send your drawings, area, and schedule via Contact. Even a simple note on "how far along" your prep is enough for us to point you to the next step.
Frequently Asked Questions
Can I get a quote with no drawings at all?
For an early budget estimate, yes — use case, approximate area, and preferred tone are enough for a range. A firm quote for cut-to-size pieces, countertops, or complex fabrication needs a drawing or a size list.
Is the waste rate always 10%?
No. It varies with layout complexity, bookmatching, and how fragile the stone type is. It's safer to separate net area from order area and agree on the rate together.
What's the difference between a slab quote and a cut-to-size quote?
A slab quote centers on piece count, dimensions, lot, and finish; a cut-to-size quote is driven by piece dimensions, edges, cutouts, and nesting. Be clear about which type you're requesting.
Is it okay to send just a PDF?
That's fine as a reference. If fabrication needs to be finalized, add a DWG/DXF file or a size list with clear dimensions — that reduces error and follow-up questions.
If the schedule is tight, what should I mention first?
Beyond the target install date, let us know your approval turnaround, whether in-stock material is acceptable, and whether same-lot or bookmatching is required. We'll propose a realistic delivery plan based on your priorities.
