Contours in Construction

Contours in ConstructionTable of Contents (Jump to)IntroductionWhat is Contour?Contours need to determine the level at various guides on the ground, and in the same horizontal position of those puts should be fixed. Vertical manoeuver exercise carried out leveling work, but the level of hold in exercised chain survey or questionnaire survey compass or aircraft to be. If the theodolite horizontal and vertical control put forward be achieved from the same mover. A profile can be classified in different groups based operator. Contour function that can be utilise to understand the shape of the land. In addition, the veridical pattern of the military control depart ph wizard you to more detailed understanding of the region. in any(prenominal) event that, physical body are divided into 2 types of methods in surveying which is check methods and indirect methods.For the direct methods, It is included in the request bring within the selected contour line of vertical and hori zontal control. Instrument officed for vertical control level. A grade level is set to take f easygoing from the commanding heights of the nearby bench mark in the region. Collimation / height of the plane of the instrument was found the staff to be read a contour line is calculated. The staff of the instrument man gestateed the staff who cultivate the required reading is found up and down movement in the region. Surveyor built using his tools of this level of control. afterwards the people of the instrument directs staff person to read another point in the same person can be found. Second is to establish the level of control. Therefore, a few points are based on a contour of one or two contour lines and proper record. Plane table survey is very suitable for the job. later on setting the points needed for the establishment of the instrument from the instrument is moved to another point in order to cover a larger area. Level and investigative tools need not be shifted simultaneou sly. That is, if two are nearby, so easy to communicate better. Get speed leveling sometimes hand level, Abney level of use. This approach is slow, tedious and inaccurate. It is suitable for sm solely areas. maculation for the indirect methods, the level of take in some selected points and their reduced levels. Thus, in this method to establish the level of control the first, then find the level of those points. After positioning point plan, the level of decline is inserted amid the selection point markers and contour lines.Sources (Methods of Contouring 2014)Diagram 1 Labeling Contour Maps (Sources http//upload.wikimedia.org/wikipedia/commons/thumb/f/fa/Cntr-map-1.jpg/300px-Cntr-map-1.jpg)What is Autocad?AutoCAD is used in creates, bridges, and com geter chip manufacturing blueprint for a com placeer-aided drawing software program. AutoCAD is mainly used for drafters, it has occurred although engineers, surveyors and architects may need to use the software. Read on to hornswogg le more. AutoCAD is in the building, construction and manufacturing for the 2-D and 3-D computer-aided drawing software applications assist blueprints and other projects prepared. Who uses AutoCAD professionals often referred to the drafting. Although the drafters in some professional work, six of the most common areas of expertness are automatonlike drawing, architectural drafting, civil drafting, electrical drafting, electronic drafting, drafting aviation.MethodologyIn methodology, I go forth describe the step that how we produce and plot a contour plan and ground section . First step is to spot the height data. At the commend there, we chance upon it the point and enter it. After we enter, it will testify a square up point then we will happen upon in the first point which is S1. For example 146.048, 313.212, 82.739. So we will key it this point and for the rest of the point like S2, S3, S4 and S5 is using the same methods. (Refer to diagram 1)Diagram 1After we state the spe cify point, we using the lines to draw a one long lines at the horizontal and vertical. After we draw a two lines, then we will click the line and type OFFSET, this will ask the distance amidst two lines and the distance is 25, so we key in 25 and enter it. thence we will click the lines beside the first lines and it will show a new lines. plot of land it was the same step as a vertical part. Make sure that the specify point it inside the box that we do. Besides that, before we draw the lines, to make sure the lines is straight we will click ORTHO MODE from shortcut we can click F8, this will automatically to help you line become straight. (refer to diagram 2)Diagram 2 enchantment next step is we firs go to home page , then we click Layer Properties. Then we will separate few layers should be use for the Buildings, Grid, Spot Height, Text, Border, Contours, Triangulated Ground Model (TGM) and Dimensions (refer to diagram 3). Then we click the point that we key in that five specify point and put it into spot heights categories. While for the boxes, we will put it into the grid categories. After that, we shimmer off the spot height and grid light bulbs. Then we will select line and key in the point A which is 168.934, 297.370. While for the rest in some step but after we key in until point F we shed to key in back to point A, then the building shape we be shown up which is building 1. While for the Building 2, is same as the building 1 just key in the coordinate. After we got this two building 1 and 2 we put it as a building categories which is highlight building 1 and 2 and click the layout and select buildings column. (refer to diagram 4)Diagram 3 4After it, turn on all the light bulbs and select text and key in the word which can see from the drawings. And the font size of the text is 3.5. The text have to key in is A, B, C, D, E, F, G, H, I, J, Building 1, Building 2, S1 (82.739), S2 (82.789), S3 (86.479), S4 (85.539) and last is S5 (84.039) (refer to d iagram 5) . Then we highlight or the text put it as a text categories. While next is find the dimension between D and G. First click to Annotate which is upper the column and then modify the dimension, select the text and key in the size is 3.5 and click ok. Then we click the OBJECT SNAP which is can click from the keyboard which is F3. This will help you to detect the point from D and G. Then we click the dimension from the Annotate and click from D to G. Then above the line, it will show the distance between 2 points. While for the point E and J is same step, so we just repeated it. Then we highlight the two dimension and put it into dimension categories. (refer to diagram 5)Diagram 5 close step is to draw a triangulated shape by using the lines from S1 to S2 and S5, then S2 to S3 and S5, Then S4 will go to S4 and S5 and S4 will go to S1 and S5. Which is means connect all the point together by using the lines. Therefore we can see the pattern is like that diagram below. Then we hi ghlight the lines for connect to each point, and put it into the Triangulated Ground Model.( ps just highlight the lines not the point like diagram below )Diagram 6After that, we click the draws which is under the lines, polyline and striation column. We select the multiple points and click the point from S1 to S4 about two point. Let say from S1 to S4 the two point is 82 and 85, therefore the number in between this two point is 83 and 84. So we will click two point between S 1 and S4 but the distance of the point moldinessiness be medium of this two point and logical dont simply click. While S1 to S5 we will click one point. And from S5 to S3 also got one point. And last from the S2 and S3 got 3 point (refer to diagram 7). After we key in the point, the select the polyline and attach the point. While it is divided into 3 lines. The first line is from the upper point which is 83 coordinate, go to the point which is S1 to S5 and go to the upper point which is S2 to S3. While the se cond lines is start from second point (S1 to S4 there) go to point S5 and last go to second point ( S2 to S3). While the third lines is from S4 to the point between (S5 to S3) and last is go to last third point for S2 and S3. If not clearly, please refer to diagram 2 and it will be understand, what am I mention about. After that, we highlight the first lines and key it PEDIT and select spline. Then the line will be slightly spline. While for the other line is same step as a line 1, highlight the line key in PEDIT and select SPLINE. While the point that use multiples points and the lines highlight all and put it into Contour categories.Diagram 7While the last step is draw a rectangular , above the grids for key in the student name and matrix ID. And last is to difference categories using the difference color like diagram 8.Diagram 8ConclusionIn my conclusion, to construct the 2D or 3D drawings is not a easy work by using manually. AutoCAD is in various fields, such as construction, mechanical, structural, civil, electrical and mechanical engineering and automotive applications. An architect can design creative ideal in any part of the building model of any type. For more instruction about AutoCAD, make complex projects simple. It combines the work of architects and engineers. From a small to a very large project, you get a precise design has great resolution. Its one of the basic drafting software, which is prominently used everywhere. Learn the software will provide design software and drawing software in the field of warm foundation. All mechanical engineers acknowledge, the prototype can be a very expensive process. The AutoCAD by eliminating the physical material and preliminary design workshop quadriceps femoris allows significant savings in the design process. Although the purchase and operation of a software package has some speak tos, which tend to be much less than the cost burden of the material and prototype shop when. As a digital simulation, AutoCAD models also allow engineers to test large-scale installations, this process will be dear(p) physical prototypes advantage.Task 2Explain how to determine areas and volume of cut and fill, using surveying data (Pass).In planning the building design and construction, architects and engineers must first consider the actual conditions of the site. In most cases, a given site is not level and must be modified before any construction can begin. Therefore, the process of cut and fill construction process is usually the first to take place at a site in one. If there is no computer software to determine the amount of land to be added or removed, we can do a simple calculation to regard the volume of cut and fill any site. First, the site is divided into sections. Essentially, the site is cut into the land segment, at a specified fixed distance, so we can look at each independent. Cutout portion is based on the land, in order to accurately represent the land topography being evaluat ed drawn. Topographic map describes the lively slope of land, and allows us to come to the site at an altitude of some of our cuts.Now, we have a two-dimensional cross-section is divided, we can foreshadow that the area to be cut and filled in the site. Each part of the cut to the desired land topography is expressed as cut line covered in the existing topography of the land line. Which brings us to two lines of each section, and tell us how many of the existing area must be removed or added. Then, the area between the lines is calculated to find the cut-and-fill each sub-region. The figure below shows the existing level lines and cutting area between the lines. From the diagram below, we can see that the start estimate how much land area must be cut off from the scene, and how much land area of the construction site must be perfect field level.Diagram 9 Cut and fillNow, once part of the region has been found, we must consider the site (land between the cut portion) of additional duration to be able to estimate the volume of land cut or fill. Finally, after the calculated value required us to determine not exclusively how much land must be removed from or sponsors website, but also where the land must be specifically taken or sponsor. annul or add any site land is an expensive process, so that our estimates are made close to the existing conditions may be important. Once we know how much land to cut or fill and cut and fill it, work can begin normal level site and build our building.Sources (Cut and encounter 2015)BibliographyCut and Fill, (2015), Online, Available at http//jwilson.coe.uga.edu/EMAT6680/Parsons/MVP6690/Essay3/cutfill.html Accessed on 1st June 2015Methods of Contouring, (2014), Online, Available at http//theconstructor.org/surveying/methods-of-contouring/6451/ Accessed on 31 May 2015
