Question: Using the survey data provided including the following files (Wg31º system), outline the method of approach :- Proj 1Q1- (2024).kcd Proj 1Q1- (2024).bot Proj 1Q1- (2024).mal Proj 1Q1- (2024).tr2 Proj 1Q1- (2024).mmb Annexure A.pdf (image file) Annexure A.jpeg (image file) Which must be accessed and downloaded from: - ‘Moodle’ – ‘Computer applications 3A’ – ‘Project 1’ – ‘Question 1’ The Topographical survey has extensively covered the area by means of an approx. 30m wide strip survey along the proposed route, which includes all natural and artificial features and existing services along the Examiner: Mr A Raghubar Computer Applications 3A (CPTA301) 2024 Semester I Page 2 of 6 road. This will serve as important information to the design and layout of the new tar road. The portion of road which is to serve as a taxi route has an expected length of approximately 5.0km upon completion. However, you are required to perform a full Road design utilising the Model maker and Road maker software to the following design specifications for a length of approximately 1.8 – 2.0km:- Design specifications for Single lane carriageway: Design speed 50km/hr Lane width 2.5m single lane Road camber - 2.5% left and right Kerb data Type: MK4 Shoulder width 1.5m slope= +4% Side slopes Cut= 1: 1 Fill= 1: 1.5 Trapezoidal Drain specifications slope 1= 1:1 width= 0.40m slope 2= 1:100 width= 0.20m slope 3= 1:1 width= 0.40m Layer works specifications: First (Top) layer: width= 2.5m thickness= 0.04m Second layer: width= 2.6m thickness= 0.10m Third layer: width= 2.7m thickness= 0.14m Road reserve= 15m Compaction factor= 0.90 Where the above design specifications cannot be satisfied, the values may be adjusted accordingly within reason, however any such changes must be justified in your report.
From the given detail, it seems like you are tasked with using topographical survey data and specific design specifications to create a model and design for a new tar road. Here is a suggested method of approach: 1. **Data Download:** Access and download all the necessary files (Proj 1Q1- (2024).kcd, .bot, .mal, .tr2, .mmb, and image files) from 'Moodle' - 'Computer Applications 3A' - 'Project 1' - 'Question 1'. Ensure you have the right software installed to open and analyze these data files. 2. **Topographical Survey Review:** Review the topographical survey data that has covered a 30m wide strip along the proposed route including all natural and artificial features and existing services along the road. 3. **Software Utilization:** Using the Model Maker and Road Maker software, you'll begin creating the model and design for the new tar road. The design should be according to the given specifications such as speed, lane width, road camber, kerb data, shoulder width, side slopes, drain specifications, and layer work specifications. 4. **Design Flexibility:** Whilst designing, if you find that the given specifications cannot be met due to geographical or other constraints, you can adjust them within reason, as per the project requirements. However, it's important to note down what adjustments you've made and why for your report. 5. **Report Creation:** Document every step taken and each design choice made in your report. Include justifications for any changes from the original specifications. You should also include visual representations and/or diagrams where possible, for clarity. 6. **Review and Refinement:** Once the initial draft of the design is completed, go through it to make sure that it is as per the design specifications. Make the necessary refinements before final submission. Remember, knowing how to manage these data files and apply them appropriately to the respective software will be crucial, and don't neglect the importance of justifying your choices in your report. It would be beneficial to also include sections in your report that discuss problems faced and how you overcame them.
