Supply-Only Window and Door Package: Builder Responsibility Matrix

In a supply-only window and door package, the supplier provides the products and documentation expressly included in the quotation and order; the local project team must separately assign design criteria, field verification, opening preparation, installation, site protection and approval responsibilities. The Builder should convert every assumption into a written matrix showing what the supplier proposes, what the local team verifies, what the installer needs and which contract or project document controls the final responsibility.

“Supply-only” is a commercial scope description, not a complete project delivery method. It does not automatically tell a Builder who measures each opening, confirms project criteria, reviews drawings, receives crates, unloads units, protects materials, installs the products or closes a missing-item issue. Those interfaces need written answers before the package is released.

Start with the signed scope, not an industry assumption

Different suppliers, installers and projects use different scope language. One proposal may include proposed product drawings, freight and delivery to a named point. Another may price only the manufactured units. A general article cannot decide which version applies.

For each interface, identify:

• what the supplier proposes or provides;
• what the local project team verifies or coordinates;
• what an installer or receiver needs to perform a separate scope;
• which contract, drawing, proposal or written order controls the answer;
• whether the item is confirmed, excluded or TBD.

Do not rely on “standard,” “by others” or “included” without identifying the specific task, document and boundary.

Use a Builder responsibility matrix

This matrix identifies questions. It does not allocate legal liability or replace the agreements among the project parties.

Define the project inputs before comparing scope

A supplier cannot quote or coordinate an undefined package. Issue current plans, elevations and a controlled opening schedule. Label preliminary dimensions and unresolved criteria. Identify the project location, delivery destination, system and finish intent, requested documentation, and known installation or access constraints.

A scope-by-scope quote comparison checklist helps normalize proposals. Use it to identify differences in products, documents, packing, freight and exclusions. Then use the responsibility matrix to assign the interfaces that remain outside the quoted supply.

Separate supplier proposals from local verification

Meruzy can coordinate proposed product dimensions and drawings from submitted plans, schedules, photographs and preliminary dimensions. Those documents support quotation and review. They are not a substitute for professional review, local verification or final production approval.

The local project team must verify site conditions and approve final production information. If the project has not verified an opening, mark it preliminary or TBD. Do not let the presence of a precise-looking number on a quotation or proposed drawing silently change its status.

For detailed field-information boundaries, review the rough-opening measurement guide. This responsibility article does not provide installation clearances or a method for converting an opening dimension into an order dimension.

Make the drawing and release process explicit

Confirm whether proposed product drawings are included, who receives them, who consolidates comments, which revision is current and who is authorized to issue production approval. Use the shop drawing review checklist for the detailed review points.

Keep commercial acceptance, document review, field verification and production authorization as separate decisions. The order should identify how comments, revisions and approvals are recorded.

Do not leave adjacent construction inside “by others”

A supply-only quotation may exclude structure, waterproofing, flashing, sealants, anchors, electrical work, interior or exterior finishes, opening preparation and installation. The article should not decide how those tasks are designed or performed. The Builder should identify the responsible project parties and the approved documents that control each interface.

Ask the separately engaged installer what product information it needs, when it needs it and which site conditions must be ready. Ask the responsible design and construction team what criteria and reviews must be completed. Record the answers without assuming the supplier has accepted work that is not in its written scope.

Clarify delivery, unloading and storage separately

Freight to a destination does not automatically include unloading, movement across the site, storage or installation. If DDP is quoted, the named destination and actual written scope matter. Meruzy can quote DDP for eligible destinations in the United States and Canada except special regions, subject to destination, access and written quotation review.

Use the DDP unloading responsibility checklist to confirm the delivery handoff. Carry the agreed destination, receiver, unloading boundary and storage owner into the responsibility matrix.

Close these questions before accepting the proposal

• Which plan and opening-schedule revision controls the quoted package?
• Which criteria are project-supplied, supplier-proposed or still TBD?
• Who verifies site conditions and final production information?
• Which proposed drawings, samples and product documents are included?
• Who collects comments and records the production-authorized revision?
• What exactly is included in packing, freight and delivery?
• Who receives, unloads, inspects, stores and protects the units?
• Who coordinates structure, envelope, adjacent finishes and installation?
• Which process controls shortages, observed damage and replacement scope?
• Which document resolves a conflict between the matrix and the signed order?

Fictional example: one line marked “installation by others”

In a fictional proposal, custom windows and sliding doors are priced with export packing and delivery to the project address. Installation is excluded. The phrase “installation by others” does not identify who verifies the openings, who provides the receiving crew, who stores the crates, or who coordinates the frame with adjacent construction.

The Builder creates a responsibility matrix. The local project team owns site verification and project criteria. The separately contracted installer reviews the approved product information needed for its scope. The quotation is clarified to state the destination and unloading exclusion. The final order identifies the controlled drawing revision and production-approval process. The matrix does not make any party liable; it prevents the tasks from remaining invisible.

Pre-order responsibility gate

Do not release the package until:

• the quoted units match the current controlled schedule;
• included and excluded deliverables are written;
• preliminary and verified information are distinguished;
• the drawing-review and production-authorization process is defined;
• local design, site and installation interfaces have named owners;
• delivery, unloading, receiving, storage and protection are assigned;
• open items are confirmed, excluded or marked TBD with a next action;
• the matrix aligns with the actual contracts and signed order.

Frequently asked questions

Does supply-only include measuring?

Do not assume it does. Confirm the supplier’s stated dimension basis and the project party responsible for field verification. The local project team must verify site conditions and approve final production information.

Does supply-only include shop drawings?

Only if they are included in the proposal or order. Confirm the intended documents, revision process, review responsibilities and production-authorization record.

Who unloads and installs the units?

The written delivery and installation scopes control. Supply-only and DDP do not automatically include unloading or installation.

Who decides whether a proposed configuration suits the project?

The supplier can provide information for the proposed configuration. The responsible local architect, engineer, contractor, installer or other qualified project professional determines requirements and suitability within its scope.

Request a written, project-specific scope

Meruzy manages and coordinates manufacturing partners for custom windows, sliding doors, folding doors, pivot doors, stairs and railings. Send the current plans, schedule, preliminary dimensions, project location and known scope boundaries through the project quote form. Project quotations, proposed product drawings and revisions are free, and there is no minimum project amount. The local project team verifies site conditions and approves final production information.

Project note: This matrix is general coordination guidance. Actual contractual, professional, delivery and installation responsibilities are determined by the project documents, responsible parties and signed order.
