Academic Year: | 2025-26 | |---------------------------|-----------| | Semester: | 4 th | | Category of the Course: | PCC | | Prerequisite: | Students should be comfortable reading civil engineering drawings and confident with math and measurement skills. | |-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Rationale: | Accurate estimation helps engineers figure out the total construction cost, wisely allocate resources, and set realistic budgets-essential steps before any project starts. In construction, a cost are shaped not just by material specification but also by equipment rentals and labor charges, so carefully calculating quantities and creating clear specifications is key to keeping expenses under control and avoiding surprises. As green building practices become more common, knowing how to estimate the costs of sustainable materials and methods is increasingly valuable. Additionally, using estimation software streamlines the process, improves accuracy, and makes it easier to update budgets as project details change. This course equips diploma civil engineers with hands-on skills in all these areas-traditional estimating, green building costing, and software tools-so they're ready for the challenges of today's construction projects. | ## Course Outcome: After Completion of the Course, the Student will able to: | No | Course Outcomes | RBT Level | |------|-------------------------------------------------------------------------------------|--------------| | 01 | Use appropriate measurement methods for various types of works. | R & U | | 02 | Perform rate analysis for different items associated with various projects. | R, U, & A | | 03 | Draft approximate estimation for various civil infrastructural projects. | U, & A | | 04 | Prepare detailed estimate of various civil infrastructural projects. | A | | 05 | Use appropriate programs/software's for estimating the quantity and cost of items. | U & A | *Revised Bloom's Taxonomy (RBT) ## GUJARAT TECHNOLOGICAL UNIVERSITY Program Name: Diploma Engineering Level: Diploma Branch: Civil Engineering Subject Code : DI04006021 Subject Name: Estimation & Costing ## Teaching and Examination Scheme: | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Total Credits L+T+ (PR/2) | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Total | |-------------------------------|-------------------------------|-------------------------------|-------------------------------|--------------------------------|--------------------------------|--------------------------------|--------------------------------|---------| | L | T | PR | C | Theory | Theory | Tutorial / Practical | Tutorial / Practical | Marks | | L | T | PR | C | ESE (E) | PA (M) | PA (I) | ESE (V) | Marks | | 03 | 00 | 02 | 04 | 70 | 30 | 20 | 30 | 150 | ## Course Content: | Unit No. | Content | No. of Hours | % of Weightage | |-------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------|-------------------| | 1 | Fundamentals of Estimating and Costing: 1.1 Estimating and Costing- Meaning, purpose, Administrative approval, Technical Sanction and Budget provision. 1.2 Classification of estimates- Approximate and Detailed estimate. 1.3 Types and Uses of Estimates: Revised estimate, Supplementary estimate, Repair and maintenance estimate, renovation estimate. 1.4 Approximate estimate- Definition, Purpose. 1.5 Methods of approximate estimate -
