Types of Surveys
The following is an excerpt from the FLORIDA ADMINISTRATIVE CODE – Chapter 5J-17.050
(10) Survey: the orderly process of determining facts of size, shape, identity, geodetic location, or
legal location by viewing and applying direct measurement of features on or near the earth’s surface using field
or image methods; defined as follows according to the type of data obtained, the methods used, and the
purpose(s) to be served:
(a) As-Built Survey: a survey performed to obtain horizontal and/or vertical dimensional data so that
constructed improvements may be located and delineated; also known as a Record Survey.
(b) Boundary Survey: a survey, the primary purpose of which is to document the perimeters, or any one of
them, of a parcel or tract of land by establishing or re-establishing corners, monuments, and boundary lines for
the purposes of describing the parcel, locating fixed improvements on the parcel, dividing the parcel, or
platting.
(c) Condominium Survey: a survey performed pursuant to Chapter 718, F.S.; includes a Boundary Survey.
(d) Construction Layout Survey: the measurements made, prior to or while construction is in progress, to
control elevation, configuration, and horizontal position and dimensions.
(e) Control Survey: a survey which provides horizontal or vertical position data for the support or
control of subordinate surveys or for mapping.
(f) Hydrographic Survey: a survey having as its principal purpose the determination of data relating to
bodies of water, and which may consist of the determination of one or several of the following classes of data:
depth of water and configuration of bottom; directions and force of current; heights and times of water stages;
and location of fixed objects for survey and navigation purposes.
(g) Mean High Water Line Survey: a survey to document the mean high water line as defined in Chapter 177,
Part II, F.S.
(h) Quantity Survey: a survey to obtain measurements of quantity.
(i) Record Survey: a survey performed to obtain horizontal and/or vertical dimensional data so that
constructed improvements may be located and delineated; also known as an As-Built Survey.
(j) Specific or Special Purpose Survey: a survey performed for a purpose other than the purposes detailed
in paragraphs (10)(a)-(i) or (k) of this rule.
(k) Topographic Survey: a survey of selected natural and artificial features of a part of the earth’s
surface to determine horizontal and vertical spatial relations.
Additionally, per an excerpt from Chaper 5J-17.051 regarding Standards of Practice
(3)(b):
1. Each survey map and report shall state the type of survey it depicts consistent with the types of surveys
defined in paragraphs 5J-17.050(10)(a)-(k), F.A.C. The purpose of a survey, as set out in paragraphs
5J-17.050(10)(a)-(k), F.A.C., dictates the type of survey to be performed and depicted, and a licensee may not
avoid the minimum standards required by rule of a particular survey type merely by changing the name of the
survey type to conform with what standards or lack of them the licensee chooses to follow.
Minimum Technical Standards
FLORIDA ADMINISTRATIVE CODE – Chapter 5J-17.052 Standards of Practice:
(1) As-Built/Record Survey:
(a) When performing as-built or record surveys, the surveyor and mapper shall obtain field measurements of
vertical or horizontal dimensions of constructed improvements so that the constructed facility can be
delineated
in such a way that the location of the construction may be compared with the construction plans.
(b) When the surveyor and mapper prepare as-built maps they will clearly show by symbols, notations, or
delineations, those constructed improvements located by the survey.
(c) All maps prepared shall meet applicable Standards of Practice.
(d) The vertical and horizontal accuracy of the measurements made shall be such that it may be determined
whether
the improvements were constructed consistent with planned locations.
(2) Boundary Survey, Map, and Report:
(a) Boundaries of Real Property:
1. The surveyor and mapper shall make a determination of the position of the boundary of real property in
complete accord with the real property description shown on or attached to the survey map or report.
2. All boundary surveys shall result in a map.
3. Any discrepancies between the survey map and the real property description must be shown.

clearly noted on survey drawing.
4. When a boundary survey updating a previous boundary survey is made by the same surveyor or survey firm for
purpose of locating non-completed new improvements, then property corners need not be reset; however, when a
boundary survey is updating a previous survey made by the same surveyor or survey firm and is performed for
purpose of locating completed new improvements then property corners must be recovered or reset. When a
boundary
survey updates a previous boundary survey made by a different surveyor or survey firm for the purpose of
locating either non-completed or completed new improvements, then property corners must be recovered or
reset.
(3) Construction Layout Survey:
(a) When the surveyor and mapper provides construction staking, these stakes must be based on controls
established using the survey standards set out in Rules 5J-17.051 and 5J-17.052, F.A.C., of this chapter.

(a) Licensees shall act as faithful agents of their clients in all professional matters.
(b) Licensees, whether or not under oath, shall not be untruthful, deceptive, or misleading, including by
omission,
in any professional report, oral or written statement, or testimony.
1. A professional report, statement or testimony is false, fraudulent, deceptive or misleading if it:
contains a
material misrepresentation of fact; omits the statement of any material fact that is necessary to form a
complete
and accurate understanding of the communication; or is intended or is likely to create an unjustified
expectation.
2. Examples of false, fraudulent, deceptive or misleading statements include: a statement that a licensee is
a
certified specialist in any area outside the licensee’s field of expertise; a statement that the licensee’s
education or experience in surveying and mapping is greater than it actually is; a statement that the
licensee’s
involvement with a surveying and mapping project will be greater than it actually will be.
(c) The licensee shall not make, publish or cause to be made or published, any representation or statement
concerning
the professional qualifications of the licensee, or those of any partner, associate, firm or organization of
the
licensee, which is in any way misleading, or which tends to mislead the recipient thereof, or the public,
concerning
education, experience, specializations or other surveying and mapping qualifications.
(d) A licensee shall not, in the practice of surveying and mapping or in any professional dealings, make,
publish, or
cause to be made or published, any representation or statement about any competitor or any other licensee
which
the
licensee knows or should know is false and which has or is intended to have the effect of injuring the
reputation or
business of such other licensee.
(e) A licensee shall not express a professional opinion that is factually insupportable or that is not based
on
accepted surveying and mapping principles, or that misrepresents data and/or its relative significance in
any
professional report, oral or written statement, or testimony.
(f) A licensee shall not violate any provisions of state or federal statutes requiring qualifications-based
selection
of professional surveying and mapping services; shall not knowingly aid or abet any other licensee in
violating
such
statutes; shall not participate in a qualifications-based selection process that the licensee knows is not
in
compliance with federal or state statutes; and shall not respond to or solicit requests that the licensee
knows
are
in violation of state or federal statutes.

other
professional documents for unlawful purposes.
(h) Licensees may not use their surveying and mapping expertise or their professional surveying and mapping
status to
commit a crime.
(i) Licensees may not knowingly associate with or permit the use of their names in a business venture with
any
person
or business entity which the licensee knows or should know is engaging in unlawful, fraudulent or dishonest
business
or professional practices.
(2) Conflicts of Interest: Licensees shall avoid any professional conflicts of interest.
(a) When conflicts cannot be avoided, licensees shall disclose to their employers and clients all known or
potential
conflicts of interest or other circumstances that could influence or appear to influence their professional
judgment
or the quality of their professional services provided.
(b) Unless the circumstances are fully disclosed and agreed to in writing by all interested parties, a
licensee
shall
not accept compensation, financial or otherwise, from more than one party for services pertaining to the
same
project.
(c) Examples of professional conflicts of interest include, but are not limited to:
1. A county employee engaging in the private practice of surveying and mapping on a project over which that
person,
as a county employee, has approval authority.
2. A licensee soliciting or accepting a professional contract from a governmental body on which that licensee
or
a
principal or officer of his/her business organization serves as a member.
3. A licensee, serving as a member, advisor, or employee of a governmental entity, who participates in its
decision
to contract for professional services from a private business in which that licensee is a principal or
employee.
(d) Licensees may not offer any bribe, commission or gift, either directly or indirectly, to obtain selection
or
preferment for surveying and mapping employment.
1. An example of prohibited activity under this subsection is a practice known as the “washout” survey,
wherein a
licensee agrees to accept payment for a surveying and mapping service only upon the contingency of a future
event
other than the completion of the survey and map.
2. The activity prohibited by this subsection does not pertain to the payment of a fee to a licensed
employment
agency for securing salaried employment as a surveyor and mapper.

or
former, in a court action to recover salaries, fees or other compensation due to the licensee as a result of
the
licensee’s employment or association with the client or employer, current or former;
(e) When necessary to defend the licensee or the licensee’s employees or associates in a legal action
alleging
wrongful conduct;
(f) When there is potential danger to the public’s safety and well being and disclosure is reasonably
necessary
to
prevent harm to the public;
(g) When the disclosures were made to the Board regarding other licensees or unlicensed individuals who may
have
violated laws or rules relating to the practice of surveying and mapping;
(h) When the disclosures relate to illegal conduct.
(4) Use of Another Licensee’s Product.
(a) Work completed by one licensee (original licensee) cannot be adopted or reused by a different licensee
(successor
licensee), except under the following circumstances:
1. With written consent of the original licensee, or;
2. When the graphics or data depicted on the survey are attributed to the licensee that was in responsible
charge
of
its production, or;
3. When the original licensee’s field notes, supporting documents and/or final product(s) are rightfully in
the
possession of the successor licensee.
(b) Use of another licensee’s work under any circumstances does not exempt the user from compliance with the
survey
requirements in Chapter 5J-17, F.A.C.
(5) Retention of Work Products.
(a) For each survey produced, all licensees, except for those who do not have an ownership right to the work
product,
shall maintain for a minimum of six years from the date of creation at least one copy of all signed and
sealed
final
drawings, plans, specifications, plats, and reports as well as one copy of all related calculations and
field
notes.
These records may be kept in hard copy or electronic or digital format.
(b) Upon the discontinuance of the practice of surveying and mapping, licensees shall ensure the safe storage
and
reasonable accessibility to clients of all files and file materials for a period of three years in
accordance
with
subparagraph 5J-17.051(2)(b)2., F.A.C. The failure to do so shall constitute cause for discipline.
1. If an individual voluntarily relinquishes his/her professional surveyor and mapper license, the transfer
and
storage of files is not required.
(6) Signing and Sealing.
(a) Licensees shall sign, date and seal those final drawings, plans, specifications, plats or reports that
have
been
prepared or issued by the licensee and conform to the Standards of Practice for professional surveyors and
