Positioning and stake a claim on Center Street; flat terrain, we can arrange evenly spaced piles but not greater than 15m. Request closed all terrain pile reflection, interchange with access roads, sewers pile in position; at the pier locations required piles; the main stakes of the curve includes first rods (TD), the bisector (P), to the end (TC) of the circular curve.
• Combining the extensive measurement standard routing, piles km, piles H and detailed measurements once among piles detail to identify the main stakes and piles detail. Using electronic total station (TDDT), steel ruler to measure the distance between the poles and the top-line closes, ask the relative error middle reaches 1/2000.
• Using Hydro mean (or total stations) High-stakes measurement details, simply measure a turn and ended at the landmark DC2. Use of mold highly technical high altitude to calculate the detailed points.
Volume is expected: Volume mapping and monitoring along the route: 300 m
(b) Measurement of horizontal monitoring
• Measuring horizontal monitoring detailed drawing 1 / 200 (Mainline): Measure paint line cross section is mapped at all monitoring pile plugged along. On each horizontal positioning accuracy monitoring 2 spindles left and right of the horizontal monitoring to guide the measure. Use indirect measure of software TDDT machine. Observation point on the horizontal measure reflects topography, animals and works especially if there is, the distance between the measurement points is 5 m biggest. Measure and record the location close to the reference location and the expected foot slope. For the existing road must show current sugar heart, edge separators, plastic edge, the edge of summer, roadside soil and talus leg, prop construction (if any). Horizontal monitoring range is measured to the end of construction (on major routes). For 70 routes along the road sides should measure the minimum population to the edge of homes (about 3m). The pile is located electric poles, columns of information within the line (drawing must clearly indicate which columns to cross).
• Horizontal Trac is measured in the vertical pile on the monitor.
Volume is expected to measure horizontal monitoring:
+ Weight: ~ 20cn x 50m / cn, Total length: 1000m
(c) survey the current state of the existing drainage system
• Update the plan for drainage, culvert placement surveys, connected from the drain into the garden existing drainage, fully embodies the drainage system vertical, horizontal drainage, manual drainage, elevation measure the current state manholes sewerage system new design with drain current connection there.
• Measure drain and cut along the flow direction of the old sewer system. The results must be expressed in the drawing (the plan, longitudinal section, the basic structure of all kinds manholes, sewer types)
Volume is expected:
- Measurement of longitudinal section drawing tools 1/100: 200m .
- digitization, registration of public utility Other: 10.
