Each maker may have varied models, together with optional features which may be tailored to local working conditions, such as accuracy requirements, project size (EDM distances), and also accessible crew size. Here is how to use a total station for this type of action: Position the device at a known point by setting the horizontal circle. [71] The station building design will feature heritage attributes by retaining the faade of buildings to be demolished for station construction. Step 5. After crossing the river, the line would pass the GO Transit Don Yard before descending into a tunnel just east of Cherry Street. [60][61] The faade of the bank building will be dismantled and preserved for use on the new station entrance building. [citation needed]. Repeatability results showed, however, that cm-level differences in coordinate The Ontario Line would share less than half the planned route of the Relief Line between Osgoode and Pape stations. A total station is an electronic/optical instrument used in modern surveying and building construction that uses electronic transit theodolite in conjunction with electronic distance meter (EDM).It is also integrated with microprocessor, electronic data collector and storage system. It will also stake out the centerline itself. [68] On February 4, Metrolinx began work to remove eleven trees on the Osgoode Hall site but had to pause work due to court injunctions, one filed by the Law Society of Ontario and later another by the Haudenosaunee Development Institute, an Indigenous organization. It then proceeded eastward through downtown along Queen Street before turning southeast in the area of Parliament Street south to Eastern Avenue. Total Station Survey System (TSSS) Survey Specications SEPTEMBER 2006 change in temperature will cause a one ppm error, if the ppm setting in the total station is not changed. Point number (you may want to use different point-numbers for the station points and topo points) Target height (for prism pole shots measure from the ground to the centre of the prism Code (depending on what your software does with it, e.g. A shoe to the pole point could is required in soft ground. Stake-Out / Set-Out. Their usage doesnt offer hard copies of field notes. When starting a construction project, it is important to know the layout of the area in which you are working. Conventional Method - Slope staking using a total station and data collector, setting Previous Next. Determine of area using Total Station 9. Other stations have connections to Toronto Transit Commission streetcar and bus services. Almost all total stations in the market use infrared as the carrier for distance measurement. From setting building corners to sighting utility lines, this sophisticated instrument provides surveyors with an important time-saving tool. Metrolinx plans to start the procurement process in 2020 to allow bidding companies to comment on the feasibility of the 2027 completion date.

It might be troublesome for the surveyor to investigate and check the work when surveying. Its northern terminus will be at Eglinton Avenue and Don Mills Road, at Science Centre station, where it will connect with Line 5 Eglinton. The main pieces ofsurveying equipmentinusearound the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod. Some of the savings for surface construction may be partially offset by the cost of building surface-to-tunnel transitions at Cherry Street and at Gerrard Street. [38], Following the awarding of major contracts in November 2022, major design and construction work of the rolling stock, systems, operations and maintenance (RSSOM) and southern civil, stations and tunnel contracts were anticipated to commence in 2023.[35][33]. 9. Engineering Supplies, Blueprint Storage, Measuring Tools, Surveying Equipment & More! Refer to 6 Safety Directions for further informa- tion. Atotal stationis an optical instrument used in modern surveying. 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. (Construction will not affect the park itself.) Adjust the total station where necessary. Trimble TSC3, Total Station or GNSS receiver, Trimble Access v2015.22, AutoCAD Civil 3D 2014/2016 . It combines the functions of a theodolite with that of a transit level and electronic distance meter (EDM).. ATheodolite is a instrument for measuring both horizontal and vertical angles, as used in triangulation networks. Metrolinx said that the original completion date was based on market conditions that since 2019 had changed dramatically. The name for an instrument of this type was electronic tacheometer, but Hewlett-Packard introduced the name total station more than 30 years ago, along with the name immediately caught on with the profession (As per below figure No 2 & 3). Step 3: Set-up the Tripod. Select "HD" to stake out using angle and distance, or "XYZ" to stake out with 3D coordinates. When classical terrestrial surveying methods are used in staking out of highway construction projects one can meet with some difficulties such . All plummets, optical or electronic, should occasionally be checked, adjusted, and calibrated. 2 Guide to using this document There are a variety of tasks that can be performed with a Total Station. Total Station is the currently preferred Surveying equipment in the industry. In the case of setting out, it makes it feasible to set control points for surveying with very little sighting through the telescope. 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. Select . [54] There are plans for an additional station entry directly from Danforth Avenue. 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. [47][48], The Ontario Line maintenance and storage facility (OLMSF) will occupy a 17.5-hectare (43-acre) site north of Overlea Boulevard, between Beth Nealson Drive and the CP Rail North Toronto Corridor. [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. INTRODUCTION This report discusses the use of the Sokkisha SET2 electronic total station for topographic surveying. Compatibility with present data collectors (if not purchased with the total station), such as (including batteries and battery life), simplicity of performance, and training requirements. Once the area has been mapped out, you can use the total station to perform a task called a stake out. Reflectorless accuracies arent as good as prism accuracies given this variability of the reflecting terrain, and can, therefore, might not be suitable for more accurate surveys like FEMA first floor elevation certifications. 1. Easily stake out mine features using the ultra-bright, high-power laser, then scan to efficiently collect georeferenced point cloud data. Read carefully through the User Manual before you switch on the product. Page 9-2 Highway Surveying Manual January 2005 Total Station System (TSS) Survey Specification Highway Surveying Manual Page 9-3 One entrance will be on the east side of Carlaw Avenue north of Gerrard Street. Then the centre lines of the rooms are set out by setting perpendiculars in the ratio 3:4:5. Once the area has been mapped out, you can use the total station to perform a task called a stake out. A set of plugs can be used to locate the total station set up in a drift or tunnel by processing measurements to the plugs by intersection and resection. Drive the tripod legs into the ground using the brackets on the sides of each leg. Aim the total station towards the reflector. STEPS. Get Traffic & Exposure. [45][49], Construction of the MSF would require the demolition of an Islamic centre and a shopping plaza that includes local businesses such as the popular Iqbal Halal Foods, serving the primarily Muslim population of Thorncliffe Park. Semiautomatic Total Stations The user needed to manually read the horizontal circle for all these instruments, but the vertical ring readings have been displayed. This will be in a corner of the gardens on the Osgoode Hall grounds. Metrolinx kept the project a secret until the government chose to announce it on April 10. [36], In July 2019, the estimated completion date was 2027. 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. Record angle and distance observations in the field. Metrolinx hired Schabas in December 2018 to lead a team to transform the Relief Line plans into the Ontario Line. In the outer range limitations, bicycle reflector tape (. Set up and use Total Station/EDM equipment for establishing control, detail surveying, setting out and coordinate checks. Under Manufacturer , select Sokkia or whichever is the correct manufacturer for your Total Station. Passengers will be able to access rail services from either the station's southwest or northeast entrance as well as from the adjacent bus terminal. Step 3: Set-up the Tripod. The staked out points were marked using the taping pins. When you see the home screen, press the "Menu" button and use the navigation arrows to move down to the "Stake Out" menu option. See More. The tribrach is about centered over the point first utilizing the standard tripod leg modification technique. A Total Station has electronic documentation and sketching functions, which reduces the need for paper field notes. South of Gerrard station, the Ontario Line would run along the northwest side of GO Transit's Lakeshore East rail corridor located on an embankment. In the 1980s, plans first emerged for a "Downtown Relief Line" that would provide capacity relief to the Yonge segment of Line 1 and the BloorYonge interchange station, and extend subway service coverage in the city's east end. The measurement results can be recorded into the internal memory and
