Metrolinx prepared the plan for the Ontario Line in just three months based on a proposal by transit consultant Michael Schabas. Conventional Method Slope staking using a total station and data collector, setting out the offset and distance from the design catches and then manually slope staking from this point. Once the site is prepared, a tunnel-boring machine will launch north and west from the site while another launches south and east towards the Don Yard. The results will be displayed on the following screen. If the specified slab elevation is above or below the reference point, figure out by how much and determine where that point should be in relation to the level plane. Decades of experience automating mine surveying plus proven results make NSS the ideal partner for Hexagon in our efforts to serve Underground customers in the US and Canada. A traditional plumb bob provides this type of check if utilized in ideal conditions. This resulted in accomplishing the stake-out of all 20,000 points in 4 days."

[44], The Government of Ontario plans to use smaller train sets and a smaller gauge for the Ontario Line than those used on the Toronto subway system. [46], The route would turn north under the east side of Berkeley Street through Corktown station at King Street. Selecting a coordinate method will give you the angle, distance and/or height, while choosing "HD" or "HDh" will give you the coordinates of the point. The main pieces ofsurveying equipmentinusearound the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod. The station is at the western of the two intersections.) A shoe to the pole point could is required in soft ground. Once the instrument has been set up, you can perform the following steps to stake out specific points: Set the instrument to a known point. [21], The announcement that the line would extend to a new station at Ontario Place stirred controversy, as Premier Doug Ford had spoken of transforming Ontario Place, previously a family-oriented venue, into an adult-oriented casino complex. [67] A consultant's report, dated February 1, 2023, and commissioned by the City of Toronto, concluded that the corner of the Osgoode Hall grounds was the best site for a headhouse based on various criteria but that the Campbell House grounds was a potentially feasible alternative site.

Total Station and Automatic Level; however may over look the importance of the tripod, prisms and staffs employed in accurately measuring and setting out. Either laser or analog plummets are utilized for final centering within a point. Focus on the prism using the large focusing knob as necessary. When these instruments are used manually, because they are servo-driven, they have friction clutches that afford great speed in point, as there are no locks to be adjusted. When the stakeout is done, the station/offset dialog appears for staking the next point. A good place to being is viewing periodic surveys by trade publications.

This Apps helps Land Surveyors and Civil Engineers to measure and collect topography survey data by connecting users Android phone/tablet to a total station by using bluetooth or a usb-serial adapter cable. Running under Queen Street, it will cross under Line 1 at the station; the Lower Queen ghost station (a remnant of the never-completed Queen subway line) will be used for transferring between the two lines. STEPS. Parts of a total station. 1 They include a wide variety of practical, automated functions to achieve the highest degree of efficiency within the shortest period. All control points used for data gathering and stake out, including photo control, are adjusted by the method of least squares. At University Avenue, the Ontario Line will run under Queen Street and cross under Line 1 at the station. Hence, it could be difficult for the surveyor to look over and assess the work whilst surveying. Pocket 3D: Creating Polyline from points.
