At East Harbour, there would be three platforms each serving a pair of tracks: one platform for Ontario Line trains, one for westbound GO trains and another for eastbound GO trains. They are listed as follows: Manual Method - Manual slope staking using a rag tape, fiberglass rod and level. Semiautomatic Total Stations The user needed to manually read the horizontal circle for all these instruments, but the vertical ring readings have been displayed. Record angle and distance observations in the field. Set up and use Total Station/EDM equipment for establishing control, detail surveying, setting out and coordinate checks. Introduction. Now Move the Instrument until comes . When used with the data collection software, the pre-determined coordinates of the point, which have been selected after setting up the instrument and making an observation to the backsight point, are used to automatically set the horizontal and vertical angles of the instrument. The contracts are:[31], On June 2, 2020, Infrastructure Ontario (IO) and Metrolinx issued a request for qualification (RFQ) for rolling stock, systems, operations and maintenance (RSSOM), marking the first phase of procurement for the Ontario Line. Extract and relate coordinate information from drawings. Figure 15-2B Hand Written Generated Slope Stake Notes There are various ways to slope stake a project, depending on which method you choose. [66]:25, In May 2022, Mayor John Tory and the Law Society of Ontario (co-owner of Osgoode Hall along with the Province of Ontario) objected to placing an entrance on a corner of the Osgoode Hall grounds as this would require the removal of a section of lawn, some urban tree cover and a section of a cast-iron fence. Conventional Method - Slope staking using a total station and data collector, setting Leica iCON iCR80 (iCR80S) features. Distance resolution is either pulsed (low precision) or phase comparison (average - 2 to t 5 millimeter(mm) accuracy). Step 5: Continue to Level and Adjust the Tribrach As Necessary. This turns 4Site Survey into an advanced mouse or digitiser . Step 4: Attach the Tribrach and Coarse Level the Tripod Over the Benchmark.

When you are satisfied with the results stake it and have the rodman write the cut or fill on the stake. A shoe to the pole point could is required in soft ground. Also, read: First Angle Projection & Third Angle Projection Symbol (Orthographic Projection). 9. Stake out using total station. [11], Since the early 21st century, studies proposed a line that would run south from Line 2 BloorDanforth at a point east of the Don River before bending westward along Queen Street into Downtown Toronto. The line would then enter Gerrard station on an elevated structure over the intersection of Gerrard Street and Carlaw Avenue. Angle typical errors range from t 1 to t 5 according to a Direct and Reverse set. According to Metrolinx, the new line will do more than provide relief to overcrowding on Toronto's existing subway system: it will provide new connections to the communities of Flemingdon Park and Thorncliffe Park. Coordinate calculation. All the equipment used stake out using total stationmeat carving knife blank. [30], The Ontario Line project is being delivered through various publicprivate partnerships (P3), progressive designbuild and traditional procurement contracts, which are all being staged accordingly for their successful delivery. user can also automatically turn the total station to the point if using a robotic instrument by pressing the Green arrow. INTRODUCTION This report discusses the use of the Sokkisha SET2 electronic total station for topographic surveying. On February 21, 2023, the Ontario Divisional Court dismissed the last injunction, allowing Metrolinx to proceed with removing the trees the next day. pegs, nails, rope or line, hammer, tape, marking tool etc) Firstly, take note of the four corners where we have the proposed columns/pillars or as case might be. Continuing west on the other side of the valley, the line would pass the Ontario Line maintenance and storage facility. It also has an integrated microprocessor, electronic data collector, and storage system that allows measurements to be stored on the device (which can be uploaded to a computer for further processing). Hence, it could be difficult for the surveyor to look over and assess the work whilst surveying. [46], Originally named Leslieville, RiversideLeslieville will be located on the railway bridge over Queen Street East on the boundary between the Riverside (west side) and Leslieville (east side) neighbourhoods.
