Construction Project Management (CPM): Definition: Involves direction, regulation, and supervision from the early stages to completion. The goal is to meet the client’s expectations regarding functionality and budget. Key functions: Includes specifying project goals, resource allocation, coordination, and managing stakeholders to resolve conflicts. Primary Functions of CPM: Specification of project scope, schedule, and budget. Acquisition of workforce and equipment. Coordination between contractors, planning, design, and construction teams. Effective communication between stakeholders to manage conflicts. Roles in Construction: Project Manager: Oversees budgeting, scheduling, and communication. Ensures project goals are met while managing teams, client relations, and resources. Contractor: Selected through bidding processes (low-bid, best-value, or qualification-based). Responsible for construction execution, meeting deadlines, and budget constraints. Bidding Process: Open Bids (public) vs. Closed Bids (private) involve different levels of transparency and contractor selection. Selection methods include Low-bid, Best-value, and Qualification- based selection, each considering price, qualifications, or a mix of both. Types of Construction Contracts: Lump-Sum: Fixed price agreed before the project starts. Unit Price: Based on quantities of work performed. Cost-Plus Fee: Reimburses contractors for costs plus an additional fee. Guaranteed Maximum Price (GMP): Limits total project costs to a maximum amount. Project Management Phases: Initiation: Establishes project objectives and feasibility. Planning: Develops work breakdown structure (WBS), risk management, and communication plans. Execution: Implements the project plan. Monitoring & Controlling: Ensures the project adheres to timelines and budgets. Closure: Final evaluation and report on project performance. Construction Project Lifecycle: Pre-Construction: Planning, budgeting, and site selection. Design: Detailed plans including architectural and structural specifications. Procurement: Acquiring materials, equipment, and labor. Construction: The actual building process. Commissioning: Final inspection, testing, and handover to the client. Delivery Methods: Different models include Design-Bid-Build, Design-Build, Construction Manager-at-Risk, and Construction Manager–Agent, each with unique approaches to project execution and risk management. There are several construction delivery methods, each with distinct approaches to managing design, construction, and project risks. Here’s a detailed breakdown of the different methods mentioned: 1. Design-Bid-Build (DBB): Process: This traditional method involves three distinct phases—Design, Bidding, and Construction. o The project owner hires a designer (architect or engineer) to prepare detailed plans and specifications. o Once the design is complete, the project is put out to bid, and a contractor is selected based on the lowest or best-value bid. o The contractor builds according to the design plans. Pros: o Clear separation of responsibilities between the design and construction phases. o Competitive bidding can drive costs down.  Cons: o The process can be time-consuming since construction doesn’t begin until the design is fully completed. o Limited flexibility for changes during construction without additional cost. Risk Management: The owner bears more risk for design errors since the contractor is not responsible for the design. 2. Design-Build (DB): Process: This method integrates the design and construction phases under one contract. The Design-Build entity (usually a contractor) is responsible for both the design and construction of the project. o The owner contracts a single entity to handle both phases, simplifying the process. o The project design and construction can occur simultaneously, speeding up delivery. Pros: o Faster project delivery since design and construction overlap. o Fewer conflicts between designers and contractors. o Cost efficiencies due to a unified team and clear communication. Cons: o Less transparency in competitive pricing since the design and construction are bundled. o The owner has less control over design since the contractor leads the process. Risk Management: Risk is more evenly distributed since the design and construction are integrated. 3. Design-Negotiate-Build (DNB): Process: In this method, the owner negotiates with a contractor during the design phase to lock in a construction contract. o The contractor is often involved early, providing input during the design phase. o Once design is sufficiently advanced, the contractor’s proposal is finalized, and construction begins. Pros:  o Early contractor involvement can lead to better cost control and design decisions that are practical and buildable. o Flexibility in contract negotiation, allowing for customization and adjustments before the construction phase begins. Cons: o The process can be less competitive since pricing is negotiated rather than openly bid. Risk Management: Early involvement of the contractor helps mitigate risk during construction due to more realistic cost estimates and design practicality. 4. Construction Manager-at-Risk (CMAR): Process: A Construction Manager (CM) is hired early in the design phase and acts as a consultant during design while taking on the role of general contractor during construction. The CM guarantees a maximum price (GMP) for the project. o The CM provides pre-construction services such as estimating, scheduling, and constructability reviews. o The construction manager assumes the risk of the construction cost exceeding the GMP. Pros: o Cost control: The contractor provides a GMP, capping the owner’s financial exposure. o Early contractor involvement enhances project efficiency. Cons: o The process is more complex and may require more management oversight from the owner. Risk Management: The CM takes on the financial risk if construction costs exceed the GMP. This method incentivizes the CM to control costs effectively. 5. Construction Manager-Agent (CMA): Process: The Construction Manager-Agent acts as a consultant to the owner without assuming financial risk. The CMA provides management expertise but does not hold the contracts with the subcontractors. o The owner holds all the contracts and assumes the financial risk for cost overruns.  o The CMA coordinates the project on behalf of the owner but has no direct control over the construction budget or scheduling. Pros: o The owner retains greater control over the project. o The CMA provides valuable management skills and guidance without taking on financial risk. Cons: o The owner must handle all contracts and financial responsibilities, which could lead to greater risk for the owner if not managed properly. Risk Management: The owner bears most of the financial risk since the CMA does not guarantee costs or the construction schedule. Summary of Risk and Control in Delivery Methods: Design-Bid-Build (DBB): High risk for the owner in terms of design errors and longer schedules. Design-Build (DB): Lower owner control, but more integrated risk management between design and construction. Design-Negotiate-Build (DNB): More flexible for negotiations but less competitive bidding. Construction Manager-at-Risk (CMAR): Offers a guaranteed maximum price, transferring construction cost risk to the contractor. Construction Manager-Agent (CMA): Provides management expertise, but financial risk remains with the owner.
