Study Notes
Construction Economics & Estimations
- Construction economics involves the study of economic aspects and principles related to construction projects.
- Key components of construction economics include cost analysis, supply and demand, and project financing.
Estimations
- Estimation is the process of predicting the costs, time, and resources required for a construction project.
- Types of estimations include:
- Preliminary estimate: rough cost estimation done in the early stages of project planning
- Detailed estimate: in-depth analysis of costs based on detailed project plans and specifications
- Bid estimate: a competitive estimate submitted by a contractor in response to a project's bid
Factors Influencing Construction Economics and Estimations
- Materials: prices and availability of construction materials
- Labor: costs associated with hiring and managing skilled and unskilled labor
- Equipment: expenses related to the use of construction machinery and tools
- Market Conditions: economic trends, inflation, and local market conditions affecting costs
- Project Scope: the size, complexity, and nature of the project
- Location: geographic factors that may impact logistics and costs
Key Processes in Estimations
- Quantity takeoff: determining the quantities of materials needed for the project based on drawings and specifications
- Unit cost estimation: assigning costs to each unit of work or material
- Overhead and profit: adding overhead costs (indirect expenses) and profit margin to the direct costs
- Contingency: including a contingency allowance for unforeseen circumstances or changes
Software and Tools
- Estimation software: utilizing specialized software like ProEst, Sage Estimating, or BuildingConnected for accurate and efficient estimations
- Building Information Modeling (BIM): integrating BIM technology for 3D modeling and collaborative project planning
Challenges in Construction Economics and Estimations
- Uncertainties: changes in market conditions, project scope, or unexpected events
- Inaccurate Information: insufficient or inaccurate data in project plans and specifications
- Regulatory Changes: changes in regulations impacting construction practices
Continuous Monitoring and Adaptation
- Cost control: regularly monitoring project costs and adjusting the budget as needed
- Value engineering: finding ways to optimize costs without compromising project quality
Documentation
- Detailed records: maintaining accurate records of costs, changes, and unforeseen events for future reference
Concept of Construction Economics
- Construction economics is a specialized branch of economics that focuses on the economic aspects of the construction industry.
- Key concepts associated with construction economics include:
- Resource allocation: efficient allocation of resources to maximize output while minimizing costs
- Cost management: identification, estimation, and control of costs associated with construction projects
- Supply and demand dynamics: understanding the market forces that influence the supply and demand for construction services, materials, and labor
- Risk analysis and management: evaluation, quantification, and management of risks
- Time value of money: recognizing the value of money changes over time
- Financial viability and feasibility: assessing the financial viability and feasibility of construction projects
- Life cycle costing: examining the total cost of ownership over a project's life cycle
- Government policies and regulations: considering the impact of government policies, regulations, and incentives on construction activities
- Sustainability and green construction: considering the economic implications of green construction methods and materials
Stakeholders of Construction Project
- Owner/client: the individual or organization that initiates and funds the construction project
- Project manager: responsible for overall project planning, execution, and completion
- Contractor: the entity responsible for executing the construction work
- Architect/designer: designs the project, develops plans, and ensures that the construction meets specified standards and regulations
- Engineers: civil, structural, mechanical, and electrical engineers play crucial roles in the planning, design, and implementation of various aspects of the construction project
- Consultants: external experts hired to provide specialized advice
- Government authorities/regulatory bodies: agencies responsible for enforcing building codes, zoning regulations, and other legal requirements
- Financial institutions: provide funding and financial support for the construction project
- End users/occupants: individuals or organizations for whom the construction project is being undertaken
Need of Estimation
- Budgeting: cost planning and forecasting
- Project feasibility: financial viability and feasibility assessment
- Decision-making: informed decision-making based on accurate estimates
- Competitive bidding: bid preparation and submission
- Resource planning: materials, labor, and equipment planning
- Project scheduling: time estimation and project timeline development
- Risk management: identification of contingencies and risk management
- Client communication: transparency and client satisfaction
- Financial control: cost control and financial management
Units of Measurement as per IS1200

- Area: worked out to the nearest 0.01 sq.m
- Cubic content: calculated to the nearest 0.01 cu.m
- Weight: worked out to the nearest 0.001 tonnes
- Thickness of RCC slab: measured to the nearest 0.005 m
- Thickness of woodwork: measured to the nearest 0.002 m
- Thickness of steelwork: measured to the nearest 0.001 m
- Length of steel reinforcement bar: measured to the nearest 0.005 m
- Diameter of steel reinforcement bar: measured to the nearest 0.0001 m
