Which assignments need a named person?
Start with the owner or authorized representative. Name the person who approves changes, accepts selections, and resolves competing requests. If several owners participate, agree on how the project team receives one approved instruction.
Then identify the providers responsible for drawings, structural input, survey work, construction, and applicable trade scopes. Use “to be assigned” for an unresolved role. That is clearer than leaving a blank that another participant may interpret as someone else’s responsibility.
Add the applicable authority as a reviewer, not a member of the contractor’s delivery team. Authority review and construction responsibility serve different purposes. Ask who handles submissions, responds to comments, and records the resulting approvals.
Where do designers, engineers, and trades contribute?
Ask the designer to define the documents and design services included in the engagement. Ask a licensed engineer to address structural design or diagnosis where the proposal requires that expertise. Confirm how their work relates to the current site plan and building layout.
For regulated trades, verify the responsible provider and required qualifications rather than using a general label such as “the construction team.” TDLR’s electricians guidance states that non-exempt electrical work requires licensing and work through a licensed electrical contractor. This source explains a trade requirement; it does not verify any company’s license.
The Houston Permitting Center also distinguishes plan submittal from trade-permit pathways. Confirm local requirements and role assignments for the property. Other Greater Houston jurisdictions may use different processes.
How should you handle owner-selected or owner-supplied items?
Separate choosing an item from purchasing, delivering, installing, and accepting it. One person may select an appliance while another needs its dimensions and installation requirements before preparing the surrounding work.
For each owner-supplied item, ask who confirms suitability, checks delivery condition, stores it, and handles missing or damaged components. Record how product information reaches the designer and installer. Do not assume installation forms part of the construction scope because the owner has bought the item.
Distinguish a visual preference from an approved product. A picture of a fixture does not establish its model, dimensions, connection requirements, or availability. Keep a selection register with product documents and the date of approval.
Which handoffs can leave gaps?
Look at interfaces between scopes. A utility provider may address one portion of a connection while a trade contractor addresses another. Ask where each responsibility begins and ends, and who coordinates the interface.
A designer may show a finish while an owner supplies it. Confirm who translates that selection into dimensions, preparation, and installation requirements. A supplier’s delivery date also needs coordination with storage and access; it should not become an unreviewed construction promise.
Document revisions create another handoff. If an engineer changes a detail, identify who updates the related drawing and who confirms that the construction scope reflects it. Sending an email attachment does not confirm that every affected participant received or accepted the change.
What should a responsibility map contain?
Make one row per task or decision. Use the following fields:
Task: the specific service, item, submission, or approval.
Responsible party: the named person or provider expected to perform it.
Input: the document, selection, or site information needed first.
Recipient: the person who needs the output for the next step.
Status: unassigned, under review, approved, or complete.
Boundary: exclusions or assumptions requiring clarification.
Review the map alongside the proposed contract documents. The map helps you ask questions; it does not amend an agreement or determine legal liability. Seek appropriate legal advice for contract interpretation.
How do you keep the map useful during changes?
Update responsibilities when the work changes. A revised layout can introduce additional design or trade review, even if the owner sees it as a small visual adjustment.
Identify who can approve that revision and who evaluates its scope implications. Retain the earlier version with a clear label rather than allowing two current-looking maps to circulate.
For commercial properties, include decision authority, operating access, and any owner-required delivery conditions. Confirm the exact contractor role before assuming specialty capabilities or an all-inclusive arrangement. For homes, identify who speaks for the household and how selections receive approval.
Responsibility questions
Only the proposed project documents can establish that arrangement. Ask who supplies design and what services the engagement includes.
Assign that role in the project documents and confirm the local process. Do not assume the owner, designer, or contractor has accepted it.
No. Use it to identify scope gaps and discuss assignments. Contract terms and professional engagements need their own review.
