Construction Manager: An individual or company employed to oversee and direct the construction elements of a project, usually the whole of the construction elements and the parties who are to perform them; a company that contracts with an owner to perform such services for a fee. The construction of a building is another, different project. However, there are many different firms and companies involved in any design-construction project and the person in charge of the project within their respective company may be called a project manager.

In the context of this chapter, the project manager is the individual assigned the responsibility to manage the design-construction project on behalf of the owner.

The project architect and general contractor or construction manager report to the project manager. The term project manager may be confused with construction manager; the meaning has become blurred and is currently often used merely for the individual within the conventional hierarchy see above.

At a minimum, this involves a design project and a construction project. These two projects, managed in harmony, constitute a design-construction program. This distinction is important as the architect is responsible for the management of the design project while the constructor is responsible for the management of the construction project. The general public as well as the architectural profession assumes that the architect protects the public interest during both design and construction.

In a complex undertaking, such as a hospital, airport or multi-use community centre, there can be additional distinct projects managed by professionals of other disciplines. These may include a land acquisition and consolidation project, a site analysis project, or a functional programming project.

All these projects together, managed by their respective project manager, project architect or project engineer, form a design-construction program. Typically, the responsibility to fill the role of program manager, the person responsible for the harmonious oversight of the many projects, is that of the client representative.

However, this role may be undertaken as an additional service provided by the architect or by a project management service provider firm. This understanding then filters to the individual contracts for delivery of design services, building construction, and the other projects needed to realize the complete endeavour. The design and construction industry continues to change.

Social, environmental and economic forces have resulted in an evolution of project delivery methods. Multiple project delivery options are available to building owners, and each has its own functions, features, benefits and drawbacks. Project delivery methods in the construction industry have evolved in response to:. Project delivery is a general term describing the comprehensive process used to successfully complete the design and construction of buildings and other facilities.

The term is used to include all the procedures, actions, sequences of events, obligations, interrelations, contractual relations and various forms of agreement. In this chapter, the traditional term construction project delivery is replaced with design-construction project delivery.

The integration of design activities and construction activities has increased over the past decade with innovations in technology, most notably building information modeling BIM , and innovations in process through integrated project delivery IPD and public-private partnerships P3s. No one other than an architect may undertake the practice of architecture beyond the exemptions noted by the provincial acts and regulations.

The practice of architecture is a protected scope under legislation, and architects remain responsible for the design, regardless of the other integrated team members and their input.

There are several ways to discuss project delivery methods. They can be discussed in terms of the responsibilities and reporting relationships of the parties in the design-construction endeavour. The functions, features, benefits and drawbacks of each method can be compared.

To provide a comprehensive overview of this critical aspect of architectural service delivery, project delivery methods will be discussed from a variety of views. The following table provides a brief executive summary of common types of design-construction program delivery.

One way of exploring different project delivery methods is through comparing the overlap of the life cycle phases of the design project to the construction project. A life cycle is the sequence of phases, from initiation to project closure, that a project goes through to achieve the stated objective. The phases of the design project vary based on the method of project delivery. Design-build projects change the relationship between the design team and the constructor and move the hiring of the consolidated design and construction team to the beginning of the design-construction program.

Construction management generally includes multiple tendering phases, resulting in overlap of the design project life cycle with the construction project life cycle. The integrated project delivery IPD method has project life cycles not dissimilar to design-bid-build but with different relationships between the project stakeholders. Construction management is a broad term covering a variety of project delivery scenarios in which the design team is augmented with the addition of a construction manager CM at an early stage to advise on and oversee such elements as schedule, cost, construction method or building technology.

A construction manager may be:. Because this method adds a construction management consultant and the associated fee, it is more commonly used when:. Occasionally an architect acts as the construction manager on projects, most often small-scale projects, such as house additions and renovations.

Construction management is not a licensed activity in most provinces. Construction managers can serve in different capacities with varying degrees of authority and responsibility advisor, agent or constructor.

Depending upon how the project is organized, a construction manager can:. At the beginning of a project, the construction manager will develop a construction budget. Construction will commence based on the budget, and as each tender package is released and subtrade contracts awarded, the budgeted construction cost becomes closer to an actual cost.

In a CCDC 5A contract, the construction manager is paid for the services delivered based on either a fixed fee, a percentage of construction cost, or an hourly rate. The construction manager is not at risk should the actual cost of construction exceed the budget. Architects and engineers who provide construction management services may decline to provide those services for construction as well, largely based upon a combination of lack of expertise and lack of appropriate insurance.

In design-build, the owner contracts with a single entity to provide both design and construction. The design team is retained by the design-builder rather than the owner. Broadly speaking, there are two variations on design-build. The advocate architect may also prepare one or more conceptual design solutions as a means of testing the statement of requirements. The advocate architect provides advice to the owner in the hiring of the design-builder and throughout construction. The advocate architect acts in the interests of the owner.

See Chapter 3. The owner retains a design-builder. A separate design team working for the design-builder prepares design documentation and provides general review during the construction.

There is a single design team working for the design-builder. Design-build projects usually have two phases:. It is not uncommon for a design-builder to expect the architect to absorb some or all pursuit design costs associated with preparing preliminary designs in competing for a project.

As a result, the architect has more at risk than other members of the design team. When architects are engaged by a design-builder to become part of a design-construction team in competition for a project, architects should insist on being compensated for their professional services. In some jurisdictions, it may be against regulations for an architect to provide services without compensation.

The following figure presents the contractual relationships between the owner, architect and design-builder in three different contractual scenarios. The three common project delivery methods place the architect in different positions in the design-construction supply chain, and therefore in different places from which to influence the primary project decision-maker, the owner.

In working with owners, design-builders or construction managers, the architect must develop strategic approaches to address the needs of the project and the key project decision-makers. Where the architect traditionally has a direct relationship with the owner, in the design-build delivery method the builder mediates in the owner-architect relationship.

This risk may be mitigated in architect-led design-build teams. Each form of project delivery has its own benefits and drawbacks. At the risk of over-simplification, these benefits and drawbacks are compared using a traditional project triple-constraint model where the scope of the project is assumed to be fixed. Change and uncertainty are inherent in undertaking projects.

Project endeavours and risk are inseparable, and no amount of planning can remove all project risks. To establish a fair exchange of value, the client and architect must recognize alignment of the project delivery risk profile with their respective risk sensitivities. P3s occur when a private sector consortium is engaged by a government or other public agency to deliver a complete capital program. The scale of a P3 project usually is significant and may include financing, design, construction, and very often facilities management and operations.

The P3 approach is controversial as it fundamentally alters the supply chain relationships in the design-construction sector.

Governments and public agencies argue that these projects would not have been possible under traditional government processes using public funds. The integrated project delivery IPD method builds on the concept that when all players in the design-construction endeavour share the same method of reward, collaboration towards higher building performance, increased value, and cost savings can be achieved. The IPD approach combines elements of other project methods but also represents innovation in the design-construction process.

Rather than the adversarial approach that is created in traditional contractual relationships, the IPD involves a multi-party contract in which the owner, architect, engineers, constructor and major trades share in the rewards of the successful project. In terms of the design-construction program described above, the integrated project delivery IPD method is designed to break down the envelope between the design project and the construction project.

The IPD contract is a restructuring of the traditional multi-project approach to form a single project with a single project team. Its aim is to create a more harmonious and collaborative working environment that will result in buildings meeting much higher performance standards and significantly increasing value for the owner. Collaboration is promoted through executive, planning and implementation teams, each with representatives of all of the major parties. Constructive collaboration is the cornerstone to this approach.

The four major phases of the integrated project delivery approach are validation, design, implementation, and warrantee. If the project appears unfeasible at this point, the owner may decide to abandon the project.

The parties to the agreement would be compensated with costs but no profit. The PMT oversees construction during the construction phase. Lean construction methods are promoted in order to increase value to the owner and the team. The warrantee phase sees the resolution of deficiencies and the final distribution of the risk pool. For a detailed discussion of the legal and contractual aspects of the integrated project delivery method, refer to Howard W. Culture can be created by both people and environment and can be transmitted from one generation to the next through family, school, social environment and other agencies.

The competitive and cost-obsessed culture of the design-construction industry does not easily lend itself to undertakings that require collaborative participation to succeed. Transforming a culture of competition to one of collaboration does not happen by accident or without effort and resources. Key elements of the planned approach are:. Project management, when defined as a project delivery method, is an adjustment to the design-construction supply chain.

In this method, an owner retains the services of a project management firm to oversee the program of planning, design and construction projects.

Construction is an extremely broad industry and every construction project is unique in its own way. Projects differ in physical size, cost to construct, geographic locale, and construction market sector. Regardless of the unique attributes that may define a project the primary objective of almost every project is on time completion that comes in on or under budget. The primary process that governs the execution of the construction process is known as the delivery method. Delivery methods are used to facilitate the selection process for project participants like the designer and the constructor, while at the same time creating parameters that will manage the entire design and construction process. Listed below are the four primary construction delivery methods currently utilized in the industry accompanied by an overview of each. The Design-Bid-Build delivery method is one of the most commonly used methodologies for managing and executing a construction project. In most cases once the construction documents are complete they are sent to General Contractors for pricing.

What are project delivery methods?

construction management project delivery methods

Every construction project requires planning, design, and execution. When planning a project, you need a construction project delivery method to organize those tasks into a well-defined contractual agreement when planning a project. The project delivery method defines the relationship between parties involved typically an owner, designer, and contractor and when and how they will fulfill their obligations and responsibilities. Ensuring that the process is clearly defined before construction begins can curtail potential misunderstandings and snags , helping the project progress more smoothly. It sets clear expectations for everyone involved, including payment processes and schedule details.

Choosing a project delivery method is an important step in the early design process. The delivery method determines how the architect and contractor execute your project and can significantly impact your budget and schedule.

Project Delivery Methods – Which Will Benefit My Construction Project the Most?

The delivery of a construction project is a complex process involving a number of parties. Project delivery methods are the methods used to take the design and construction of a project from its conception to its completion and handover to the principal. Through an understanding of the different project delivery methods an informed decision can be made as to which is the best method for a particular project. Appropriate contractual arrangements can then be adopted. Choosing the right project delivery method for a project will not ensure success, but it should go some way towards avoiding disputes and time or cost blow-outs.

When you choose us to not only manage the project, but to work as the contractor, we become your CM at risk. This way, you not only have our project management experience on your side; you have our investment in the outcome of your project. Design Build is a model under which the client engages us to take an already-developed concept, complete the detailed design, and, after final client approval, proceed with construction. Because this model involves the builders early on in the design process, it creates an opportunity to reduce cost without reducing function, as well as the possibility of a quick turnaround time from inception to completion.

Within construction, as with many industries, there are many possible project delivery methods.

A traditional method to deliver a project, the project owner separately hires an architect to perform the design, and then the contractor completes it according to those specifications. In this construction delivery method, a single design and build team works together from the beginning to deliver a unified approach throughout the project. In this method, the contractor, or construction manager, agrees to adhere to a guaranteed maximum price for the project, regardless of overages incurred.
