Cost Control I Study Notes

Cost Control in Construction Projects

  • Importance of Cost Control

    • Ensures projects are completed within budget, maximizing value.
    • Helps identify potential cost overruns early in the design and construction phases.
    • Facilitates informed decision-making regarding resource allocation and project modifications.
    • Maintains quality standards while controlling costs.

  • Need for Cost Control in Different Phases

    • Design Phase:
    • Establishes a budget based on scope and design requirements.
    • Allows for value engineering – optimizing project function and minimizing cost.
    • Helps in assessing the feasibility of designs against financial constraints.
    • Construction Phase:
    • Monitors actual spend versus budget in real-time to manage cash flow.
    • Adjusts ongoing work in response to emerging financial data.
    • Collective evaluation of contractor performance against cost targets.

  • Application of Cost Control Techniques

    • Use of software for tracking costs and timelines
    • Regular financial reporting and variance analysis
    • Implementing project management methodologies like Agile or Lean to optimize resources
    • Involvement of all stakeholders (e.g., architects, engineers) in cost discussions early.

Storey-Enclosure Method Principles

  • Principles of Storey-Enclosure Method in Approximate Estimating:

    1. Consistency and uniformity in measurement methods.
    2. Accurate identification of building elements and their associated costs.
    3. Inclusion of all relevant variables ensuring no underestimation.
    4. Use of historical data for estimation to predict future costs accurately.

  • Influence of Cost Factors

    • Functional Cost Factors: Aligns costs with the intended functions of space.
    • Technical Cost Factors: Concerns with the technology used in construction phases, which influences labor and material costs.
    • Aesthetic Cost Factors: Design choices impacting decoration and finish costs.

Design Variables Affecting Cost

  • Three Design Variables:
    1. Site Conditions: Topography and soil quality influencing foundation requirements.
    2. Material Selection: Quality and type of materials selected. High-end materials increase the overall cost.
    3. Building Geometry: Complex shapes increase labor and material usage, affecting total costs.

Advantages of Cost Planning

  • Cost Planning Advantages:
    1. Improves overall cost control and management during all phases.
    2. Enhances communication and transparency among stakeholders.
    3. Provides a structured approach to resource allocation.
    4. Supports risk management through well-informed budget forecasts.
    5. Enables scope adjustments that do not compromise on quality or budget.
