Construction Management Study Notes

Construction Plans and Specifications

  • Definition and Importance
    • Construction plans and specifications serve as the basis for construction and materials management.
    • The operations on-site dictate much about materials management.
  • Job Site Overview
    • Construction job sites are busy environments with various activities and personnel.
    • Key characteristics include supervision, tools, equipment, and often chaotic organization.
  • Public Perception
    • Public perception of construction sites includes annoyance and frustration, typically due to noise and disruptions.
    • Proper organization and management of job sites can lead to a better public image.
    • Exemplary management includes managing disruptions and communicating effectively with nearby residential and business communities.

Role of General Contractors

  • Authority and Responsibility
    • General contractors have ultimate authority on job sites and are responsible for means and methods of construction.
    • Responsibilities include overseeing subcontractors and trades, ensuring organizational aspects, managing environmental impacts, documenting activities, and maintaining public relationships.
  • Traits of a Construction Job Site
    • Common descriptors include:
    • Loud
    • Dusty
    • Chaotic

Job Site Organization

  • Organizing the Job Site
    • General contractors establish site organization, including temporary offices and hours of operation.
    • Example of operational hours: concrete pours might need to start early but must adhere to local noise ordinances in residential areas.
  • Challenges of Scheduling
    • Effective scheduling is critical to avoid workforce wasting time; trades should only be scheduled when the site is ready for them to work.
    • Importance of coordinating construction trades and ensuring materials are available when needed.
    • Failure to do so incurs costs and can lead to frustration among workers and management.

Construction Operations and Management

  • Key Areas of Focus
    • Layout, productivity, safety, quality control, and environmental impact.
    • Safety is paramount, involving all personnel returning home safely each day.
  • The Trifecta of Construction Management
    • Safety at the center of the triangle:
    • Time (schedule)
    • Cost
    • Quality
  • Quality Control and Assurance
    • Essential in avoiding costly mistakes and maintaining relationships, as poor quality affects profitability.

Subcontracting and Coordination

  • Trend toward Subcontracting
    • Modern contractors predominantly subcontract work rather than handling tasks themselves, making effective coordination even more critical.
  • Scheduling Issues
    • Avoid scheduling workers on-site until ready to work to limit inefficiencies and costs.
    • Always verify that required materials are present for specific tasks (e.g., rebar for steel work).

Safety and Risk Management

  • Big Four Safety Hazards
    • Falls: leading cause of construction injuries.
    • Struck-by incidents: individuals or objects colliding.
    • Caught-in/between incidents: employees getting trapped or crushed.
    • Electrocutions: primarily from faulty equipment or maintenance.
  • Environmental Concerns
    • Managing dust, noise, runoff, and traffic impacts.
    • Implement Storm Water Pollution Prevention Plan (SWPPP) to mitigate impacts and comply with regulations.

Material Management

  • Importance of Accurate Tracking
    • Essential to verify delivery of materials to ensure correct quantities and types are present before starting work.
  • Documentation and Communication
    • Promptly inform suppliers of discrepancies in materials, emphasizing communication to avert misunderstandings.
  • Productivity Management
    • Balancing manpower effectively to avoid diminishing returns; being understaffed or overstaffed can impede productivity.

Environmental and Waste Management

  • Managing Waste and Debris
    • Importance of maintaining a clean job site to prevent injuries and uphold public perception.
  • Job Site Logistic Planning
    • Creating logistics plans that detail waste management, access points, and material storage.

Summary and Key Takeaways

  • The leader in construction management—superintendents—carry the overall responsibility for site operations, safety, quality, and environmental impacts.
  • Strong coordination among trades and effective scheduling are critical to successful construction operations, necessitating a strategic approach to planning and execution.
