Question: Using the survey data provided including the following files (Wg31º system) write an intriguing introduction :- 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.
Leveraging the extensive data provided through thorough survey files including Proj 1Q1- (2024).kcd, Proj 1Q1- (2024).bot, Proj 1Q1- (2024).mal, Proj 1Q1- (2024).tr2, Proj 1Q1- (2024).mmb, and relevant image files available in ‘Moodle’ under ‘Computer applications 3A,’ and ‘Project 1,’ 'Question 1’, we delve into a mission aimed at curating an efficient and beneficial tar road design. The meticulous topographical survey, focused on a approximate 30m wide strip onto the aspired route, grants us a comprehensive understanding of the area and its features, both natural and artificial. An integral part of planning our new tar road design, it provides us with crucial information about existing services in the neighborhood. Anchoring on the blueprint for a taxi route of approximately 5.0km, our task is to carve out a substantial road design covering 1.8km -2.0km using specialized software like Model Maker and Road Maker. The proposed design, consisting of a single-lane carriageway, incorporates carefully-calculated specifications including a design speed of 50km/hr, lane width of 2.5m, and a road camber at 2.5% left and right. Further technicalities include a MK4 Kerb type, shoulder width, cut and fill side slopes, trapezoidal drain specifications, and layer work provisions, all meticulously designed to ensure maximum efficiency and safety. A road reserve of 15m is kept with a compaction factor of 0.90. In situations where the design specifications falter, appropriate adjustments may be made pragmatically, with a requirement for precise justification in the report. This promising initiative gives us an opportunity to create a comprehensive, beneficial and environment-friendly road design.
