land – Here’s What to Expect at a Listing Appointment
Railroad surveys are conducted either during the initial design and construction process or to aid in ongoing maintenance projects. Surveyors assist engineers in the mapping of optimal rail routes, and also determine optimal grades, slopes, and curves in varying sections of the rail route.
The railroad survey is an essential step before any drawings can be made of potential railway routes. It is necessary to understand the geographic restrictions and the layout of the area before attempting to determine the best route. In an ideal world, the rail line would run in a perfectly straight line from start to finish, with no changes in slope and no turns, since this would be the shortest distance. If this were possible, a surveyor may not be necessary. However, in the real world there are geographic obstacles that nearly always make this impossible.
As the surveyor determines the optimum rail route, there are a few restrictions to keep in mind. First, the rail line should climb no more than two meters in altitude for every 100 meters traveled. When it comes to curve, gentle curves (under 10 degrees) are optimum, though tighter curves may be possible or even necessary in some areas. One major difference between highway surveying and railway surveying is in how angles are measured. On highways, curves are defined using the ARC method, while railway surveyors use the Chord Method. This method allows for easier determination of curves in the field. When determining optimum route, the surveyor also takes into account the track gauge (how far apart one rail is from the other), and regulations such as maximum train length, if any exist.
During this step of the railroad design process, the surveyor is mostly concerned about the track, since no other design elements will be relevant if the track is unusable. Other than providing location input, the surveyor may also create a 2D or 3D representation of the site. Often this takes form as a cross section, allowing viewers to see how the railway will look from the site itself. In other cases, the surveyor’s work takes the form of a 3D computer generated image showing the line’s ideal location when current geography is considered. This image may be manipulated to allow viewing from any side or angle.
Perhaps the most challenging part of rail road surveying is the necessity of bridges and tunnels. The surveyor may be responsible for providing input on site selection and monitoring the building process to ensure that the bridge or tunnel is located correctly. The surveyor’s job is made more difficult when tunnels are involved rather than bridges, as the tunnel must be bored completely straight through the hill or mountain.
Land brokerage companies will generally charge a commission fee of 5% to 10% depending on the size and sale price of the property. A discount broker may charge you less money, but the marketing of your land may suffer because the agent does not feel like they can afford to outlay much money on it. 10% seems a little steep, but on smaller parcels of rural land an agent may legitimately feel they need that much to make it worth their time. Commissions may be negotiable with the agent, so feel free to ask if they will move on the percentage. All of my personal listings are at the same percentage of commission because in order to provide the best service I cannot skimp on the quality of marketing, so that each property has the best opportunity to attract qualified buyers. Landowners can be sure they are getting my best deal and best effort on each property they list with
