How to Brief Your Joinery Contractor: A Guide for Interior Designers & Architects in Dubai
A clear brief means an accurate price and an on-time delivery. Here's exactly what your joinery contractor needs from you to make that happen.
At Petra Wooden Industries, we receive hundreds of briefs every year — ranging from complete hotel fit-outs to a single joinery unit for a residential building. The single biggest difference between projects that run smoothly and those that cause stress is the quality of the initial brief.
This doesn't mean everything needs to be fully resolved before you contact us — we understand that designs evolve. But the clearer the initial information, the more accurate the pricing, the more reliable the timeline, and the smoother the project runs.
This guide is written for interior designers, architects, and main contractors who want to submit the best possible brief.
The Essential Briefing Checklist
These are the documents and information we need to get started. Having these ready will significantly speed up the inquiry phase.
Architectural drawings (DWG or PDF)
Floor plans, elevations, and sections at 1:50 minimum
Material & finish schedule
Veneer species, lacquer colours, hardware references (e.g. Blum, Hafele)
Key dimensions
Ceiling heights, floor build-up, any structural constraints
Site access details
Floor, lift dimensions, working hours, site supervisor contact
Programme / handover date
Works backward from your handover — we need to know your critical path
Procurement route
Are materials client-supplied (CS) or contractor-supplied? Specify per item
Approvals required
Which sign-offs are needed? Mock-up, sample board, shop drawing approval?
Shop Drawings: Why You Can't Skip Them
Shop drawings are the detailed technical documents we prepare based on your architectural drawings. They show exactly how each joinery piece will be built — including internal dimensions, joint details, hardware layouts, and connection information with other building elements.
Approving them isn't a formality — they are the legal record of what has been agreed. Any changes requested after approval generate change instructions that impact time and cost.
Our advice: allocate proper time to review shop drawings. Involve the client or architect if needed. An hour of careful review at this stage is worth weeks of avoided delays later.
Factory Tip
If the site has level issues or uncertain structural elements, ask us to do a site visit before shop drawings are finalised. Discovering problems on site is far cheaper than discovering them during installation.
How Lead Times Work
Custom joinery lead times are not negotiable in the same way that pricing might be. Here's what a typical programme looks like:
Inquiry & Quotation
3–5 working days
Shop Drawings
1–2 weeks
Client Approval
Depends on your response speed
Production
3–8 weeks depending on scope
QA & Finishing
Built into production phase
Delivery & Installation
2–7 days depending on site
The takeaway: work backwards from your target handover date and engage your contractor as early as possible. Sharing early-stage drawings (even if not fully resolved) allows us to begin preliminary preparation.
The 5 Most Common Briefing Mistakes — and How to Avoid Them
Based on decades of working with designers and contractors, these are the costliest mistakes at the briefing stage.
Sending mood boards instead of drawings
Mood boards inspire — they don't price. Without dimensions and material specs, any quote is a guess. Always pair visuals with technical drawings.
Leaving hardware unspecified
"Soft-close hinges" and a Blum Aventos lift system are not the same budget. Specify hardware by brand and model, or ask your contractor to recommend equivalents.
Not confirming site conditions
An out-of-square wall or a last-minute floor level change can add weeks to the programme. Share your floor build-up and structural survey before production begins.
Skipping the shop drawing stage
Shop drawings are your last opportunity to catch errors before CNC cutting. Approve them carefully — they are the legal record of what was agreed.
Treating lead time as flexible
Custom joinery is made to order. A 6-week lead time means 6 weeks of factory time — it cannot be compressed without affecting quality or programme for other clients.
