SECTION 617 - RIGHT-OF-WAY MARKERS
617.01 Description. This work consists of furnishing and placing right-of-way markers
and permanent easement markers in accordance with the plans and these specifications and at points designated on the plans, or as directed. The work also shall include the removal of right-of-way markers from their original locations and resetting at new locations as specified or established. Generally, Type “A” markers shall be placed in the ground and Type “B” markers shall be placed in concrete areas. The estimated quan tity of markers will be shown on the plans, and it is the Contractor’s responsibility to verify the type and number of markers required.
617.02 Materials. The right-of-way marker and pe rmanent easement markers shall be
constructed using a reinforcement bar of the size indicated and a brass or bronze cap as indicated on the plan sheet. The cap shall be Mark-It® Model C/M-HS-3-1/4B, Berntsen® 6000 Series, or approved equal. The cap sh all be stamped with information indicated on the plans. The rebar shall meet the requirement of Section 711 of the Standard specifications. Right-of-way markers for placement in concrete shall be Mark-It® model C/M-SS-3-1/4B, Berntsen® C Series, or approved equal brass or bronze stem designed marker. The cap shall be stamped with information indicated on the plans. The witness post shall be made of fiberglass or Poly Vinyl Chloride (PVC) and shall not rust, rot or corrode within the service temperature range of -40°F to 140°F. It shall be of the color and size indicated in the plans or co ntract documents. The color shall not be painted on the marker but shall be pigmented into the material composition of the post. The post shall feature ultra violet (U.V.) i nhibitors to eliminate cracking, pealing and deterioration of the post.
617.03 Construction Requirements.
617.03.1 General. Markers shall be manufactured in accordance with the details shown
on the plans and the requirements of this section. Prior to installation, the rebar shall be checked to assure there are no large burrs or mushrooming on the end that will receive the brass cap. Any burrs shall be filed or ground off before installation. The Contractor shall use rebar drivers to eliminate mushrooming of the rebar during the driving operations. Type “B” markers may be installed in freshly placed concrete or placed in cured concrete by drilling and anchoring. The marker shall be anchored using a bonding material recommended by the manufacturer of the marker. The Contractor shall use specially designed post drivers or other means necessary to eliminate damage to the witness posts during installation. The Contractor will not be required to place witness posts in concrete. All letters, symbols, and other markings shall be as shown on the plans and shall be neatly imprinted in the caps. The markers shall be set at the locations desi gnated on the plans, or as directed by the Engineer with assistance as need ed by the District Surveyor. The markers shall be set to within 1/4 inch of the lines indicated or established and a minimum of two inches below to a maximum of six inches below the natural ground elevation. The layout and placement of right-of-way ma rkers shall be performed by, or under the supervision of, or directed by, a Licensed Professional Surveyor who is duly licensed and entitled to practice as a Professional Surveyor in the State of Mississippi and shall have responsible charge for these duties. The duties performed by said Professional shall conform to the definitions under the practice of “land surveying” in Mississippi Law. The location of the markers shall be as shown in the plans. Accuracy standards for placement of markers shall be 0.05 feet relative to the project control established by the Department using either State Plane Coordinate monuments or centerline control monuments used for construction or those accuracies as listed in the Mississippi State Board of Licensure for Professional Engineers and Surveyors publi cation entitled “Standards of Practice for Surveying in the State of Mississippi.” The more stringent of these two accuracy standards will apply and shall be used. The Contractor shall not engage the services of any person in the employ of the Department for the performance of any of the work covered by this Section or any person who has been employed by the Department within the past six months, except those who have legitimately retired from service with the Department during this period. The Department will establish, one time only, State Plane Coordinate System horizontal control monuments. It shall be the responsibility of the Contractor to establish additional control as may be required to facilitate the staking of the right-of-way. Control monuments set by the Contractor shall meet the minimum standards of surveying as required by the Mississippi State Board of Li censure for Professional Engineers and Surveyors. The accuracy of the control established by the Contractor shall be not less than 1:20,000 relative to the control provided by the Department. The Contractor shall reference, guard and protect control points from damage and obliteration. The Contractor shall verify the accuracy of the control points before proceeding with the installation.
617.03.2 Removal of Existing Markers. Existing right-of-way markers and permanent
easement markers specified to be removed shall be removed in accordance with the plans or as directed by the Engineer without additional compensation.
617.03.3 Certification. After all markers are insta lled, the Licensed Professional
Surveyor tasked with responsible charge for this installation shall submit a written certification to the Engineer certifying that all right-of-way markers were set at the locations designated on the plans, or otherw ise directed by the Department, and to the specified tolerances. The certification shall also include a copy of the right-of-way plan sheets with the right-of-way marker / permanent easement table(s) completed for all locations in which the Licensed Professional Surveyor installed right-of-way markers and permanent easement markers. The table shall be completed showing the as-built (in-place) northing and easting location based on the State Plane Coordinate System. Each right-of- way plan sheet shall be signed and stamped by the Licensed Professional Surveyor. The Licensed Professional Surveyor tasked w ith responsible charge will furnish a signed and stamped Final Right-of-Way Plat meeting the minimum standards of surveying for a Class A, B, or C survey as required by the Mississippi State Board of Licensure for Professional Engineers and Surveyors. In no incidence shall the standards for surveying be less accurate than a Class C survey. The Final Right-of-Way Plat shall show all horizontal control points, whether provided by the Department or by the Contractor. In addition, the as-built project alignment shall be shown with stationing, curve data, and State Plane Coordinates for the BOP, PC’s, PT’s, and EOP.
617.04 Method of Measurement . Right-of-way marker s and permanent easement
markers will be measured by the unit. Markers shall be measured for payment as follows: 50% of the quantity placed upon completion of the installation of the marker and witness post. Remaining 50% of the quantity placed upon the submission of the Final Right-of- Way Plat.
617.05 Basis of Payment . Right-of-way markers and permanent easement markers,
measured as prescribed above, will be paid fo r at the contract unit price per each, which shall be full compensation for all the components and imprinting necessary for the right- of-way marker / permanent easement markers, the witness post and surveying decals, right- of-way plat, all labor, materials and incident als necessary to furnish a complete in-place
Right-Of-Way Markers in other states
