Compare land surveying proposals by checking whether each one will deliver the same usable information at the same project milestone. A lower total is not a like-for-like price if it omits the street connection, surface model or boundary work the designer needs.
Make vague scope lines answerable
The examples below are illustrative review questions, not standard Terrane package terms.
| If the proposal says… | Ask for… |
|---|---|
| “Topographic survey” | A marked limits exhibit and a defined feature list, including needed off-site connections. |
| “CAD included” | The file format, units, coordinate and elevation references, and whether a usable surface is included. |
| “Utilities included” | The systems and information sources included, plus responsibility for locating or exposure. |
| “Delivery Friday” | The specific deliverable, whether it is preliminary or final, and the information or access required to hold that date. |
| “Revisions included” | The type and extent of revisions covered, and how changed designs or added fieldwork are handled. |
Have the receiving designer review it
The architect or civil engineer who will use the survey can often identify a scope gap that is hard to see in a fee summary. Ask them to check the limits, required features and delivery files before the work is awarded.
For example, one proposal may include the parcel but exclude the street where the engineer expects to connect drainage. Another may include that connection. Compare the cost of a complete assignment rather than assuming the difference is simply one surveyor charging more.
Give every exclusion a home
An exclusion is not necessarily a defect. It is a question for the project team: will this work be needed, and who is doing it?
Review title documents, utility investigation, traffic control, specialist delineations and additional visits where relevant. If the design depends on an excluded item and no one has commissioned it, the project still has an unresolved cost and schedule dependency.
Our guide to preparing a survey request helps establish the common brief. Use that same brief to clarify differences between the proposals received.
Define completion and the change process
Distinguish the field visit from the delivery the team can work from. Confirm whether the quoted date covers a preliminary base, signed survey or recorded document, and what must be supplied before the schedule begins.
Then check how extra work is authorized. A new design, inaccessible area or expanded mapping limit may change the assignment. The proposal should explain how the added scope and fee will be agreed upon.
Before selecting, answer three questions: can the receiving team use the promised deliverable, are likely additional costs identified, and does the delivery date match the next project decision? Once those answers align, the price comparison becomes meaningful.
