Integrated project delivery

Last updated

Integrated project delivery (IPD) is a construction project delivery method that seeks the efficiency and involvement of all participants (people, systems, business structures and practices) through all phases of design, fabrication, and construction. [1] IPD combines ideas from integrated practice [2] and lean construction. The objectives of IPD are to increase productivity, reduce waste (waste being described as resources spent on activities that do not add value to the end product), avoid time overruns, enhance final product quality, and reduce conflicts between owners, architects and contractors during construction. [3] IPD emphasizes the use of technology to facilitate communication between the parties involved in the construction process.

Background

The construction industry has suffered from a productivity decline since the 1960s [4] [5] while all other non-farm industries have seen large boosts in productivity. Proponents of Integrated project delivery argue that problems in contemporary construction, such as buildings that are behind schedule and over budget, are due to adverse relations between the owner, general contractor, and architect.

Using ideas developed by Toyota in their Toyota Production System and computer technology advances, [6] the new focus in IPD is the final value created for the owner. In essence, IPD sees all allocation of resources for any activity that does not add value to the end product (the finished building) as wasteful. [7]

IPD in practice

In Practice, the IPD system is a process where all disciplines in a construction project work as one firm. The primary team members include the architect, key technical consultants as well as a general contractor and subcontractors. The growing use of building information modeling in the construction industry is allowing for easier sharing of information between project participants using IPD and is considered a tool to increase productivity throughout the construction process. [3]

Unlike the design–build project delivery method which typically places the contractor in the leading role on a building project, IPD represents a return to the "master builder" concept where the entire building team including the owner, architect, general contractor, building engineers, fabricators, and subcontractors work collaboratively throughout the construction process.

Multi-Party Agreements

One common way to further the goals of IPD is through a multi-party agreement among key participants. In a multi-party agreement (MPA), the primary project participants execute a single contract specifying their respective roles, rights, obligations, and liabilities. In effect, the multi-party agreement creates a temporary virtual, and in some instances formal, organization to realize a specific project. Because a single agreement is used, each party understands its role in relationship to the other participants. Compensation structures are often open-book, so each party's interests and contributions are similarly transparent. Multi-party agreements require trust, as compensation is tied to overall project success and individual success depends on the contributions of all team members. [8]

Common forms of multi-party agreements include

The role of technology in IPD

The adoption of IPD as a standard for collaborative good practice on construction projects presents its own problems. As most construction projects involve disparate stakeholders, traditional IT solutions are not conducive to collaborative working. Sharing files behind IT firewalls, large email attachment sizes and the ability to view all manner of file types without the native software all make IPD difficult.

The need to overcome collaborative IT challenges has been one of the drivers behind the growth of online construction collaboration technology. Since 2000, a new generation of technology companies evolved using SaaS to facilitate IPD.

This collaboration software streamlines the flow of documentation, communications and workflows ensuring everyone is working from 'one version of the truth'. Collaboration software allows users from disparate locations to keep all communications, documents & drawings, forms and data, amongst other types of electronic file, in one place. Version control is assured and users are able to view and mark up files online without the need for native software. The technology also enables project confidence and mitigates risk thanks to inbuilt audit trails.

Criticism

A significant criticism of IPD that the single-minded focus on efficiency is often associated with a lack of concern for employee safety and well-being. This led to a poor safety performance and increased stress levels among construction workers, as they strive reach higher goals with less resources. [7]

Job Order Contracting

Job Order Contracting, JOC is form of integrated project delivery that specifically targets repair, renovation, and minor new construction. It has proven to be capable of delivering over 90% of projects on-time, on-budget, and to the satisfaction of the owner, contractors, and customer alike. [9]

Design–build, also known as alternative delivery, is a project delivery system used in the construction industry. It is a method to deliver a project in which the design and construction services are contracted by a single entity known as the design–builder or design–build contractor. It can be subdivided into architect-led design–build and contractor-led design–build.

Project delivery methods defines the characteristics of how a construction project is designed and built and the responsibilities of the parties involved in the construction. They are used by a construction manager who is working as an agent to the owner or by the owner itself to carry-out a construction project while mitigating the risks to the scope of work, time, budget, quality and safety of the project. These risks ranges from cost overruns, time delays and conflict among the various parties.

Design–bid–build, also known as Design–tender, traditional method, or hardbid, is a project delivery method in which the agency or owner contracts with separate entities for the design and construction of a project.

Building information modeling (BIM) is a process involving the generation and management of digital representations of the physical and functional characteristics of buildings and other physical assets. BIM is supported by various tools, technologies and contracts. Building information models (BIMs) are computer files which can be extracted, exchanged or networked to support decision-making regarding a built asset. BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain buildings and diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels.

A punch list is a document prepared during key milestones or near the end of a construction project listing works that do not conform to contract drawings and specifications that the general contractor must correct prior to final payment. The work may include incomplete or incorrect installations or incidental damage to existing finishes, material, and structures. The list is usually made by the owner, architect or designer, or general contractor while they tour and visually inspect the project.

Lean construction is a combination of operational research and practical development in design and construction with an adoption of lean manufacturing principles and practices to the end-to-end design and construction process. Lean Construction required the application of a robust programmatic framework to all repair, renovation, maintenance, and or new build activities. While each project may be unique, the application of LEAN fundamental should be applied consistently. Lean Construction is concerned with the alignment and holistic pursuit of concurrent and continuous improvements in all dimensions of the built and natural environment: design, construction, activation, maintenance, salvaging, and recycling. This approach tries to manage and improve construction processes with minimum cost and maximum value by considering customer needs.

Design technology, or D.T., is the study, design, development, application, implementation, support and management of computer and non-computer based technologies for the express purpose of communicating product design intent and constructability.

Construction law is a branch of law that deals with matters relating to building construction, engineering, and related fields. It is in essence an amalgam of contract law, commercial law, planning law, employment law and tort. Construction law covers a wide range of legal issues including contract, negligence, bonds and bonding, guarantees and sureties, liens and other security interests, tendering, construction claims, and related consultancy contracts. Construction law affects many participants in the construction industry, including financial institutions, surveyors, quantity surveyors, architects, carpenters, engineers, construction workers, and planners.

Construction cost estimating software is computer software designed for contractors to estimate construction costs for a specific project. A cost estimator will typically use estimating software to estimate their bid price for a project, which will ultimately become part of a resulting construction contract. Some architects, engineers, construction managers, and others may also use cost estimating software to prepare cost estimates for purposes other than bidding such as budgeting and insurance claims.

Fast-track building construction is construction industry jargon for a project delivery strategy to start construction before the design is complete. The purpose is to shorten the time to completion.

A construction contract is a mutual or legally binding agreement between two parties based on policies and conditions recorded in document form. The two parties involved are one or more property owners and one or more contractors. The owner, often referred to as the 'employer' or the 'client', has full authority to decide what type of contract should be used for a specific development to be constructed and to set out the legally-binding terms and conditions in a contractual agreement. A construction contract is an important document as it outlines the scope of work, risks, duration, duties, deliverables and legal rights of both the contractor and the owner.
