All land survey work accomplished under the contract shall conform to the requirements and standards of appropriate State laws governing surveying activities within the State for which the contract is written. In public land States conformance to the Bureau of Land Management (BLM) Manual is required by Federal law on all lands bordering or encompassed by public domain, and may be required by State law on private land. This guidance shall be followed unless otherwise directed by the Contracting Officer. All references to the U.S. Fish and Wildlife Service Manual are incorporated as part of this contract by reference.
B. Responsibility for Work
An individual licensed as a land surveyor in the State for which the contract is written shall assume all responsibility for the work performed under the contract. The Contracting Officer must approve any substitutions of individual responsibility for this work. Only individuals fully qualified to accomplish the assigned work shall be utilized on projects under this contract.
All work accomplished under the contract shall be under the supervision of a Land Surveyor licensed in the State for which this contract is written.
D. Coordinate Base
The work performed under the contract shall be based upon the State Plane Coordinate System unless another coordinate base is authorized, or directed, by the Contracting Officer.
All survey equipment utilized on projects under the contract shall be of such design, adjustment and condition that the results obtained will fulfill and maintain the degree of survey accuracy as specified in each delivery order.
A. Land Surveying
For the purposes of the contract, land surveying shall be defined as the application of all available technologies for the purposes of: the location and re-location of boundaries; the construction of plats and maps; and the determinations of positions, lines, elevations, areas and volumes.
A tract shall be considered to be an area of land in one ownership which may consist of contiguous parcels to which one tract number will be assigned by the Contracting Officer and for which one tract report will be prepared and furnished by the Contractor.
The boundary lines may require the blazing, hacking and painting of trees on Federal land. The trees along the boundary line, on Federal land, will be marked so as to be easily seen by a casual observer, marking shall be spaced approximately 12-20 m (-40-60 ft). Only special paint specifically for tree marking will be used. When required, the marking shall conform to the requirements in Exhibit A, (Marking Government Lines) unless alternative instructions are provided in the delivery order.
All land survey corners and boundary corners accepted or reestablished under the contract shall be monumented by the Contractor. The monument shall consist of a standard Service monument (or other monument approved or provided by the Contracting Officer). The monument shall be stamped by the Contractor using appropriate metal dies showing: the year; State license number of the land surveyor responsible for the survey; and markings necessary to identify the position of the corner (BLM designations in public land States or the tract and corner number in non-public land States), and may bear, for ready reference, a serial number (reference 343 FW 2.5B).
Monuments shall be set as follows:
(I) Cultivated fields
Placement in cultivated fields shall be made in such a way that will leave the bottom of the monument on undisturbed material and the top of the monument at least 30 cm (-l ft), but no more than 45 cm (-18 in), below natural ground surface or as directed by the Contracting Officer or the Contracting Officers Representative (COR).
(2) Gravel or Dirt Roadways
Placement in roadways shall be made in a way that will leave the bottom of the monument on undisturbed material and the top of the monument at least 12 cm (-5 in), but no more than 20 cm (-B in), below the gravel or dirt roadway surface.
(3) Bituminous Asphalt Macadam-Surfaced Roadways
When specifically directed by the Contracting Officer or COR, the Contractor shall set monuments on bituminous asphalt macadam-surfaced roadways, the monument shall be placed with the top 10 cm (-4 in) below the roadway surface and within a cast iron monument case, or equivalent, set with the top of the monument case flush with the macadam roadway surface. The Contractor is responsible for obtaining any required clearances from appropriate State or county governments.
(4) In areas at which corner monuments will not be disturbed by cultivation or traffic, placement shall be made in such a way that the top 10 cm (-4 in) of the monument is above the original ground surface.
(5) In situations where bedrock or a sound boulder surface is encountered before reaching the required depth, the monument stem may be cut to a fitted length and firmly anchored to the rock with concrete. If the sound boulder surface is within 5 cm (-12 in) of the ground surface a brass or aluminum tablet should be set in a concrete filled drill hole flush with the rock surface.
B. Reference Marks
All corners monumented under the contract, or previously monumented by the Government, at which reference marks are missing, shall be witnessed by the Contractor in the following manner:
(1) Cultivated Fields
Posts shall be set as required in the delivery order. Carsonite posts shall be used unless otherwise specified. When metal posts are specified, the Contractor will be required to provide metal "T" posts with minimum cross-section dimensions of 3 x 3 x 0.3 cm (1 3/8 x 1 3/8 x 1/4 in) thick and with a minimum length of 1.8 m (-5 ft). Posts shall be set at locations not likely to be disturbed (fence lines, etc.) driven firmly, shall be free-standing, and shall be set with a minimum of 1 m (-3.3 ft) of post above the ground.
When metal posts are used, each post shall have a 7.5 x 12 cm (3 x 5 4-n) survey location poster attached to its top. The survey location poster shall be as illustrated, provided, and/or approved, by the Contracting Officer.
The following data shall be stamped on the survey location poster: the corner designation, the distance and bearing from the post to the monument shall be stamped or otherwise permanently marked on the location poster and recorded in the field notes.
Set two (2) posts with location posters and marking as described above, at locations least likely to be disturbed (fence lines, etc).
(3) Areas Where Corner Monuments Will Not Be Disturbed
Set one (1) post with a location poster as described above, appropriately marked and vertical, within 1 m (-3.3 feet) of the monument and located at a 45 angle to the cardinal direction from the monument.
(4) Areas Where Setting a Reference Mark is Not Practical
Bearing and distance measurements, as defined in above, from the "set" or "found" corner to at least two (2) easily identified prominent physical features such as spikes, bolt heads, marked bridge abutments, etc., shall be recorded in the field notes. If possible and practical, a location poster marked as described above shall be attached to said feature.
(5) Setting of Posts
Posts shall be driven by weighted tubular post drivers and care shall be used in driving and handling posts to avoid damage to the surface of the post. Any post which is split, twisted or bent, or which has a deformed top shall be removed and replaced with a satisfactory post.
C. Retracement Surveys and Ties

(3) Analytical Aerotriangulation
The Contractor shall perform semianalytical stereotriangulation or preferably analytical aerotriangulation to compute the adjusted coordinate positions and elevations of all paneled points and the coordinate positions of the corners to be established and/or reestablished under the contract. The accuracy of said coordinates shall be in accordance with the requirements of the contract. Use of the analytical aerotriangulation solution is recognized as a basic surveying tool for locating, reestablishing, and establishing land survey corners. The Contractor shall make necessary measurements from the paneled points, make diligent search for evidence of the original corner markers and comply with all other applicable requirements of the contract for retracement surveys made by conventional ground survey methods.
