621.01.01 General. This work consists of perpetuating survey monuments.
MATERIALS
621.02.01 General. Materials shall conform to the following Section and Subsection:
Portland Cement Concrete ................................ ..................................................................................................................... Section 501 Bar Steel Reinforcement ......................................................................................................................................... Subsection 713.03.01 Concrete shall be Class A or Class AA Portland cement concrete. The NPS 6 [168.3 mm (6.625 in.) outside diameter] galvanized steel pipe riser for survey monuments shall conform to ASTM A53, Type S, Grade B, Schedule 40. The NPS 5 [141.3 mm (5.563 in.) outside diameter] steel pipe for the cover for survey monuments shall conform to ASTM A53, Type S, Grade B, black finish, 3.96 mm (0.156 in.) minimum wall thickness. The welded steel cover for survey monuments shall conform to ASTM A36. Welding shall conform to Section 506. The cast iron cover and ring for survey monuments shall conform to Subsection 712.03.02. The bronze disks for survey monuments shall be commercial quality survey monuments. Provide bronze disks meeting the requirements of the governmental agency having jurisdiction thereof. CONSTRUCTION
621.03.01 Installation. Concrete construction shall conform to Section 502.
Perpetuate survey monuments at existing monument location. Excavate a hole for the survey monument to the required depth. Place concrete for base. Install the bronze disk in the required position for the survey monument after the concrete has set sufficiently. Construct risers and covers as shown on the plans. Label the survey monument covers with the word “Survey.” Use letter heights of at least 25 mm (1 in.). Perpetuate the monuments according to Nevada Revised Statutes Chapter 329 & 625, by a Licens ed Nevada Professional Land Surveyor, and tie to 2 existing NDOT construction control monuments utilizing NDOT’s Special Instruction for Survey or Mapping Consultant’s Manual, which is available from the NDOT Location Division. Public Land Survey Corners are to be set in a survey well and referenced by 4 tie monuments set outside the const ruction zone. Send a copy of the recorded Corner Record for each monument with a written report by the land surveyor identifying the character, location, description, and ties of the new monument to the Chief Land Surveyor, Headquarters Building, 1263 S. S tewart Street, Carson City, Nevada 89712. All found stamped or tagged survey monuments and public land survey corners will be listed in contract plans. Perpetuate all such monuments if they will be destroyed by construction activities. Notify the Engineer of any other survey monuments discovered during construction, which are not listed in the contract plans, which may be disturbed by construction activities. Perpetuate any such discovered survey monuments if directed. METHOD OF MEASUREMENT
621.04.01 Measurement. The perpetuating of survey monuments will be measured by the each.
621 MONUMENTS BASIS OF PAYMENT
621.05.01 Payment. The accepted quantities, measured as provided above, will be paid for at the contract
price per unit of measurement for the pay item listed below that is shown in the proposal. Payment will be full compensation for the work prescribed in this Section. When a bid item is not provided for perpetuating survey monuments, and if directed to perpetuate any discovered survey monuments, the perpetuation of the survey monuments will be paid for as extra work according to Subsection 104.03. Payment will be made under: Pay Item Pay Unit Perpetuate Survey Monument ................................ ................................ ........................................................................................... Each SECTION 623 SIGNALS, LIGHTING , AND INTELLIGENT TRAFFIC SYSTEMS DESCRIPTION
623.01.01 General. This work consists of furnishing and installing, modifying or removing traffic signals, traffic
signal master control assemblies, controller cabinets, vehicle detection systems, pedestrian push buttons, interconnection facilities, ramp metering systems, flashing beacon systems, highway lighting systems, high mast lighting systems and high mast raising and lowering devices, sign illumination systems, traffic count stations, communication conduit, traffic monitoring stations, electrical equipment in structures, falsework lighting, partial installations for future systems, or combinations thereof. This work also consists of furnishing and installing fiber optic cable including distribution equipment, splicing, and jumper cables. This work also consists of furnishing and installing emergency vehicle optical detector (EVOD) systems at signalized intersections on signal standards and in control cabinets. The locations of traffic signal control equipment, power services, lighting system standards and masts, illuminated sign structures, conduit runs, and all other appurtenances shown on the plans are approximate and the exact locations will be established in the field. Determine the exact location of all utilities, aerial and buried, that may interfere with equipment and systems installation. See Subsections 105.07 and 107.17. All systems and system components must pass functional tests and be completely operational before final acceptance. Where an existing system is to be modified, reuse the existing material in the revised system, or remove, salvage, and stockpile or abandon as shown on the plans, as specified in the Special Provisions or as directed. Unless otherwi se specified, haul and stockpile salvaged materials not incorporated into the new system to an approved site designated by the owner or as designated. Such material shall remain the sole property of the owner.
