Overview

Documentation and supervision are inseparable aspects of professional surveying practice. Every measurement, observation, decision, and analysis must be documented in a manner that supports the survey's conclusions and withstands scrutiny. Simultaneously, the licensed surveyor must exercise meaningful supervision over all aspects of the work, ensuring that subordinates perform their duties competently and that the final product meets professional standards.

The PS exam tests these concepts because they go to the heart of professional responsibility. A surveyor who cannot demonstrate adequate documentation and supervision exposes the client, the public, and the profession to risk.

Key Concepts

Responsible Charge

Responsible charge is the legal standard defining the level of control and direction that a licensed surveyor must exercise over surveying work. While specific statutory language varies by state, the core concept is consistent: the licensed surveyor must exercise independent control and direction, using initiative, skill, and independent judgment.

Elements of Responsible Charge

Element	Description
Independent control	The licensed surveyor makes the technical decisions, not someone else
Direction	The surveyor directs how the work is performed, not just reviews it after
Initiative	The surveyor proactively identifies issues and determines solutions
Skill	The work requires the application of professional knowledge and training
Independent judgment	The surveyor exercises professional judgment, not just following orders

What Responsible Charge Is Not

Misconception	Reality
Merely reviewing completed work	Must be involved throughout the process
Signing and sealing another's work	Must have directed the work, not just endorsed it
Financial responsibility	The legal concept is about technical control, not financial liability
Physical presence at all times	Does not require being in the field at every moment
Delegating all technical decisions	Cannot delegate the exercise of professional judgment

Figure PS.2.10 — Supervision Levels in Professional Surveying

Levels of Supervision

Professional surveying recognizes different levels of supervision appropriate to different situations:

Direct Supervision

The licensed surveyor is personally present and actively directing the work. This level is appropriate for:

Complex boundary determinations requiring real-time professional judgment
Training new crew members on critical procedures
Situations where immediate technical decisions are needed
Work in areas with significant liability exposure

General Supervision

The licensed surveyor assigns work with instructions and reviews results, but is not continuously present. Appropriate for:

Experienced crew performing routine measurements under established procedures
Topographic surveys following standard protocols
Construction staking from computed plans
Data collection by trained technicians using approved methods

Responsible Charge Without Physical Presence

A surveyor can maintain responsible charge of work being performed at a remote location if:

Clear, detailed instructions are provided before the work begins
Communication is maintained during the work (phone, radio)
The surveyor reviews and evaluates results before they are finalized
The surveyor makes all professional judgments about the work
The surveyor is available to respond to field questions and issues

Common wrong path — signing and sealing work you did not direct. A licensed surveyor cannot sign and seal a document based on another person's work — even another licensed surveyor's — unless the sealing surveyor exercised responsible charge over that work. "Responsible charge" requires actual direction and judgment, not just review of completed work. This rule most commonly appears when: (a) a license-holder is asked to "sign a plat prepared by [another licensee who has since left the firm]"; (b) a license-holder plans to seal work performed under a prior employer's supervision; (c) a license-holder wants to seal work done by an unlicensed subordinate with no direction from the licensee. All three are violations of most state surveying practice acts. The seal represents a professional warranty that the work was performed under the licensee's responsible charge. Exam questions test this by describing a scenario where a surveyor is asked to sign another's work; the correct response is to decline unless the signer actually directed the work.

Quick retrieval check — try before reading on.

▶A colleague at your firm was the surveyor of record for a boundary survey completed last month. They just left the firm and did not seal the final plat. The client is calling to ask for their sealed plat. The firm asks you, also a licensed surveyor, to sign and seal the plat since you're the only licensee available. Can you do so?

No — you cannot seal work you did not supervise. Even though you are a licensed surveyor and the work was performed by another licensed surveyor at your firm, you were not in responsible charge of the survey. Signing and sealing the plat would be a violation of the state surveying practice act and of professional ethics.

Professional options: (1) Ask the former employee to seal the plat before leaving the firm (typically the simplest solution); (2) personally redo the relevant portions of the survey under your own responsible charge — review the records, inspect the field evidence, verify the monumentation — before sealing; (3) perform a full peer-review equivalent redoing the work from scratch; (4) engage another surveyor (possibly the former employee as a subcontractor) to seal the work. Just slapping your seal on another's work to satisfy the client is a clear violation that exposes your license. If the firm pressures you to seal regardless, decline in writing and escalate to the appropriate authority within the firm or, if necessary, report the pressure to the state board. Your license is worth more than any single client relationship.

Field Documentation

Field Notes -- Fundamental Principles

Field notes are the contemporaneous record of observations made during survey work. They serve legal, technical, and historical purposes. The fundamental principles of field note keeping are:

Principle	Application
Contemporaneous	Record observations at the time they are made, not later from memory
Complete	Include all information needed to reconstruct the survey
Accurate	Record exactly what was observed, not what was expected
Permanent	Use permanent media (ink, not pencil); never erase or destroy
Clear	Organized, legible, and understandable to other professionals
Objective	Record facts and observations, not unsupported conclusions

Essential Field Note Content

Category	Items to Document
Administrative	Date, weather, crew members, project name/number
Equipment	Instrument make/model/serial number, calibration date
Setup	Station description, instrument height, backsight reference
Observations	Raw angles, distances, rod readings, GPS data
Evidence	Monument descriptions (type, size, condition, markings), occupation evidence
Sketches	Sufficient detail to reconstruct the survey layout and feature relationships
Anomalies	Discrepancies, damaged monuments, unexpected conditions
Decisions	Choices made in the field and the reasoning behind them

Monument Descriptions

Monument descriptions in field notes should include:

Type and material (iron pipe, rebar, concrete, stone, etc.)
Size (diameter, length)
Condition (in place, tilted, broken, bent, loose)
Cap or tag information (license number, name, designation)
Surface features (flush, above grade, below grade, in pavement)
References to nearby features (distances and directions to stable objects)
Whether the monument was found, set, reset, replaced, or could not be found

Electronic Field Records

Modern data collectors store observations electronically. Documentation requirements for electronic records include:

Requirement	Implementation
Backup	Daily download and backup of all data files
File naming	Consistent naming convention (project-date-crew-sequence)
Point numbering	Systematic numbering scheme documented in field book
Code list	Feature codes defined and provided to all crew members
Supplemental notes	Written field notes for evidence, descriptions, and sketches not captured electronically
Data integrity	Verify data completeness before leaving the field

Office Documentation

Project Files

A complete project file should contain:

Document	Purpose
Contract/proposal	Scope of work, client expectations, fee arrangement
Records research	Copies of recorded documents, title reports, prior surveys
Control data	Published and established control coordinates, datums
Field notes	Original field books, data collector downloads, backup copies
Computations	Traverse closures, adjustments, area calculations, coordinate computations
Correspondence	Letters, emails, and communications related to the project
Working maps	Draft versions showing development of the boundary opinion
Quality checks	Documentation of checks, reviews, and verification procedures
Final deliverables	Maps, plats, reports, legal descriptions issued to the client

Computation Records

All computations should be documented to allow verification:

Input data clearly identified
Computation method stated
Software used (name, version) documented
Intermediate results shown
Final results clearly stated
Checks applied and documented
Person performing computations identified
Person checking computations identified (when applicable)

Record Retention

Surveying records must be retained for specified periods. Requirements vary by jurisdiction, but common standards include:

Record Type	Typical Retention Period
Original field notes	Permanently (or as long as the firm exists)
Computations	Minimum 10 years (varies by jurisdiction)
Final maps and plats	Permanently
Correspondence	Minimum 5-10 years
Electronic data	Same as the paper equivalent

Many professional liability policies require retention of records for the duration of the statute of limitations for professional negligence claims, which varies by jurisdiction but may extend 10 years or more from the date of discovery of an alleged error.

Disposition of Records

When a surveyor retires, dies, or closes a practice, the disposition of survey records is a matter of professional and often legal obligation:

Records should be transferred to another licensed surveyor or professional entity
Some jurisdictions require notification to the licensing board
Records may be deposited with the county surveyor or other public repository
Destruction of records before the retention period expires may constitute professional misconduct

Quality Management

Review Procedures

Professional quality management for survey documents includes:

Review Type	Description
Self-review	The person who performed the work reviews it before passing it forward
Independent check	A second person verifies computations and evaluates results
Technical review	A senior surveyor reviews methodology, evidence analysis, and conclusions
Final review	The surveyor in responsible charge reviews and approves the final product

Common Documentation Errors

Error	Prevention
Missing monument descriptions	Use a checklist for each monument visited
Incomplete instrument information	Record equipment details at start of each session
Undocumented decisions	Note the reason for every field decision in real time
Insufficient sketches	Sketch before leaving each setup
Missing atmospheric data	Record temperature and pressure with each EDM setup
Inconsistent units	Establish unit convention at project start and document it

Interim vs. Final Documents

The distinction between interim and final survey documents is important for both legal and practical reasons.

Interim Documents

Marked "PRELIMINARY," "DRAFT," "FOR REVIEW ONLY," or similar notation
Do not bear the surveyor's seal
Used for internal review, client discussion, or agency review
Subject to change based on review comments or additional information
Should not be relied upon for legal, construction, or boundary purposes

Final Documents

Bear the surveyor's seal, signature, and date
Represent the surveyor's professional opinion at the time of issuance
Suitable for recording, construction, legal proceedings, and reliance by third parties
Must comply with all applicable standards, regulations, and professional requirements
Cannot be modified without formal revision procedures (new seal, signature, date)

Exam Tips

Responsible charge requires independent control and direction, not just review of completed work
Field notes must be contemporaneous -- recorded at the time observations are made
Monument descriptions in field notes should include type, size, condition, markings, and references
Never erase or destroy original field notes; make corrections by striking through with a single line
Electronic field data requires the same backup and documentation standards as paper records
The surveyor in responsible charge must review and approve all final documents before sealing
Interim documents must be clearly marked as preliminary and should not bear the surveyor's seal
Record retention periods vary by jurisdiction but typically require permanent retention of field notes and final maps
Quality management includes self-review, independent check, technical review, and final review
