Constructability: A Pivotal Asset to Project Management

Constructability stands as a fundamental instrument in effective project management. A constructability leader must embody a comprehensive skill set and demonstrate extensive experience in the field, ensuring proficient execution of construction projects.

DEFINITION (WIKIPEDIA)

“Constructability (or buildability) is a concept that denotes ease of construction. It can be central to project management techniques to review construction processes from start to finish during pre-construction phase. Buildability assessment is employed to identify obstacles before a project is actually built to reduce or prevent errors, delays, and cost overruns.”

INHERENT FACTORS  IN CONSTRUCTABILITY: CONSIDERATIONS

Inherent factors in constructability are pivotal considerations that significantly impact project success:

Construction knowledge and methodology, encompassing scheduling, sequencing, and site planning.

Accessibility, necessitating the minimization of road blockages and optimization of materials deliveries and exits.

Innovation as a driver of progress, fostering the adoption of cutting-edge practices.

Effective team skills for seamless collaboration among stakeholders, enhancing project efficiency.

Environmental consciousness guiding decisions towards building practices that enhance efficiency, reduce energy consumption, and minimize waste generation.

Proactive risk management involving early visualization and mitigation of potential hazards, endorsing the adoption of less risky concepts to safeguard project integrity.

CONSTRUCTABILITY AT EACH STAGE OF THE PROJECT

Feasibility studies: In the initial stages of feasibility studies, our focus is on anticipating potential issues and developing proactive approaches to prevent, navigate, or efficiently resolve them.

Preliminary engineering: In the early phases of the engineering process, we apply principles of constructability to enhance “Safety by Design” practices. This involves influencing the design process by considering factors such as planning, potential construction methods, and the selection of materials. Additionally, we conduct thorough assessments of local construction expertise to determine the feasibility of incorporating customary methods and actively engage with Value Engineering to optimize project outcomes.

Detailed design: In the detailed design phase, we thoroughly analyze various aspects of work area planning, including deliveries, crane operations, hoarding areas, and loads on existing structures, as well as potential interactions with neighboring structures, utilities, tunnels, and other factors. Furthermore, we collaborate with value engineering to optimize both functionality and costs, while also evaluating procurement timelines’ impacts on the project schedule. We also assess the trade-offs between construction speed and expenditures engage with planners to address any clashes between construction activities and project schedules.

Construction: Throughout the construction phase, we conduct thorough reviews of the contractor’s schedule in relation to the progress of construction activities. Simultaneously, we examine possibilities for environmental optimization to ensure sustainable practices are implemented.

Processes will encompass constructability reviews at every stage, ensuring that all stakeholders consider constructability:

  • Conducting constructability reviews during project planning to anticipate risks, identify scheduling bottlenecks, and address integration issues.
  • Integrating constructability reviews into design processes to assess constraints and incorporate them into planning, phasing, and procurement, thereby enhancing ease of construction within the design.
  • Implementing constructability reviews to optimize planning and waste management strategies.

MASTERING CONSTRUCTABILITY: KEY TO PROJECT SUCCESS

In summary, constructability involves the efficient and timely construction of projects while maintaining adherence to initial requirements. It stands as a critical component of project management.

Multidisciplinary experts must visualize the project comprehensively, much like elite athletes, in order to ensure seamless coordination throughout all project stages. Their involvement spans from inception to completion.
