Fast-track construction

Last updated

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. [1]

Benefits

Shorter schedules are desirable for reasons that vary with building owners. A shorter schedule may reduce a manufacturer's time-to-market, a school district's need to reduce overcrowding or simply provide a new home for a family sooner. Shorter schedules may also reduce the cost of construction financing and reduce overhead costs for the design and construction organizations. Shorter schedules may also reduce the impact of inflation during construction. The fast-tracking of the project is therefore achieved through the integration of design and construction phases.

Fast-track is more difficult to manage than the traditional design–bid–build process. It requires detailed knowledge of the process, effective planning, integrity and close coordination among the organizations executing the work.

Inherent risks

The final cost of the project is uncertain when construction begins because design is not complete. [2] With the traditional design–bid–build process, a complete set of construction documents and specifications describes what the builder agrees to build and serves as the heart of the contract. On Fast-track projects, the design, construction documents and specifications are incomplete, so setting the final cost presents problems. To deal with this difficulty, owners typically use a cost-reimbursable contract with the builder (a construction manager or a general contractor). The contract may include a cost estimate with no guarantee or there may be a Guaranteed Maximum Price (GMP). However, even with a GMP, there can be argument over the scope of work covered by the GMP since the design was incomplete when the contract was executed.

There is also a risk that work built in an early phase of the project may not suit later design decisions. For instance, if the building shape changes after the foundations are built, there is increased cost and delay to modify the completed foundations. Or an item of equipment that is selected late in the process may require drains or water and power connections that were not anticipated early in the project. Furthermore, the interpretation of the design brief from the contractor may differ from the owner which can result in a conflict of interest.

If time is not crucial, owners may take a prudent approach to finish design and get a fixed lump-sum price before starting construction (the design–bid–build process). However, if there is a reason to speed project delivery, Fast-track can be used with any project delivery strategy, such as CM at Risk and Agency CM (see Construction management), design–build, bridging and integrated project delivery. Even the traditional design–bid–build process can use Fast-track concepts by bidding separate general construction contracts for phases of the work.

However, many owners choose experienced project teams and consider the rewards to be well worth the risks. One source states that Fast-track is used on 40 percent of building projects. [3]

History of the process

For most of the 19th and 20th centuries, the common project delivery process was sequential design–bid–build, with a time period between the completion of one phase and the start of the next one. An architect and/or engineer completed a design, made detailed construction drawings, wrote specifications and invited multiple contractors to submit proposals stipulating their price to execute the project., [4] [5]

Typically, government organizations preferred a "lump sum" bid for all phases of the work (all off design-build) and were also required to award construction work to the lowest qualified bidder. The political assumption was that the low lump sum bid demonstrated a prudent use of public money, and open competitive bidding demonstrated a fair selection of contractors. Since competitive lump-sum bidding required complete construction drawings and specifications, Fast-track as used in Industry was unavailable to public owners.

However, most public procurement regulations allowed procurement of architectural, engineering and other services based on the qualifications of the service provider. (See the Brooks Act [6] for the approach used by the federal government.)

In the 1960s, during the Vietnam War, students enrolled in higher education were deferred from the draft. Consequently, colleges and universities exploded. The crowding problems were acute because the delivery of design and construction for academic buildings usually took 4 to 6 years. Meanwhile, the high rate of inflation was eroding construction budgets. [7] A 4-5 year project schedule might see the buying power of appropriated funds for building projects reduced significantly.

In 1968, The New York State University Construction Fund (SUCF) [8] retained Caudill Rowlett Scott (CRS) to study ways to shorten schedules. [9] The completed study hypothesized that the SUCF could save 25–45 percent of the time with phased construction. They could stay within their procurement regulations by selecting a company (a CM) for construction management services—who would provide no construction labor or materials—on the basis of qualifications.

The CM would do no actual construction work. The CM would have a professional responsibility to represent the owner's best interest as an agent, similar to that of an architect.

The CM would advise the architect and owner on cost and construction technology during the design phase and would estimate the total cost. The architect would complete the construction drawings and specifications in phases and the CM would take open, competitive bids for those phases of the work, overlapping the design and construction activities. For instance, the CM might take bids for site clearing and grading as soon as the basic building configuration was set and drawings and specifications for that phase of the work were complete. Companies that typically functioned as subcontractors would bid the work. The low bidder would have a direct contract with the owner, metamorphosing from subcontractor to prime contractor. The owner would have multiple prime contracts.

It was not an entirely original concept. There had been a few previous examples of similar processes—Tishman Construction (now part of AECOM) provided Construction Management services for the World Trade Center that was built with phased construction (construction begin in 1966, the building was destroyed September 11, 2001).

SUCF accepted CRS's Fast-track report and retained Smith, Hinchman & Grylls (now the SmithGroupJJR) to implement their first Fast-track project at Stony Brook University, Stony Brook, New York. The Stony Brook project and CRS's later projects demonstrated that the projected time savings were conservative. Sometimes the use of Fast-track and CM reduced time to a third or less of conventional schedules. [10] [11]

The report was titled "Fast-track". Many copies were printed. The concept of a professional construction manager that could implement phased design and construction (Fast-track) for public projects spread rapidly. The United States General Services Administration and many other institutional and government clients throughout the U.S. adopted the process.

However, despite the advantages of a shortened schedule, many owners didn't like the management responsibility for multiple prime construction contracts on a single project and were concerned about the lack of a guaranteed maximum price. In the late 1900s and early 2000s many government organizations changed their procurement regulations to allow the CM to hold the contracts and guarantee price and schedule. To differentiate between the original concept and an additional concept of CM services, the original was called Agency CM and the CM that held the contracts and provided guarantees was called CM at-Risk (see Construction management).

Fast-track is now a common term throughout the US construction industry.

Construction is a general term meaning the art and science to form objects, systems, or organizations, and comes from Latin constructio and Old French construction. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure.

A business proposal is a written offer from a seller to a prospective sponsor. Business proposals are often a key step in the complex sales process—i.e., whenever a buyer considers more than price in a purchase. When one person signifies to another their willingness to do or to abstain from doing anything with a view to obtaining the assent of the other to such act or abstinence, they are said to make a proposal.

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 are systems used by a construction manager or owner 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.

A general contractor, main contractor, prime contractor, builder (UK/AUS), or contractor is responsible for the day-to-day oversight of a construction site, management of vendors and trades, and the communication of information to all involved parties throughout the course of a building project. In the USA a builder may be a sole proprietor managing a project and performing labor or carpentry work, have a small staff, or may be a very large company managing billion dollar projects. Some builders build new homes, some are remodelers, some are developers.

Construction management (CM) is the use of project management techniques and software to oversee the planning, design, construction and closeout of a construction project. It aims to control the quality of a project's scope, time, and cost to maximize the project owner's satisfaction.

Project engineering includes all parts of the design of manufacturing or processing facilities, either new or modifications to and expansions of existing facilities. A "project" consists of a coordinated series of activities or tasks performed by engineers, designers, drafters and others from one or more engineering disciplines or departments. Project tasks consist of such things as performing calculations, writing specifications, preparing bids, reviewing equipment proposals and evaluating or selecting equipment and preparing various lists, such as equipment and materials lists, and creating drawings such as electrical, piping and instrumentation diagrams, physical layouts and other drawings used in design and construction. A small project may be under the direction of a project engineer. Large projects are typically under the direction of a project manager or management team. Some facilities have in house staff to handle small projects, while some major companies have a department that does internal project engineering. Large projects are typically contracted out to engineering companies. Staffing at engineering companies varies according to the work load and duration of employment may only last until an individual's tasks are completed.

Construction bidding is the process of submitting a proposal (tender) to undertake, or manage the undertaking of a construction project. The process starts with a cost estimate from blueprints and material take offs.

In construction, commissioning or commissioning process is an integrated, systematic process to ensure, through documented verification, that all building systems perform interactively according to the "Design Intent". The commissioning process establishes and documents the "Owner's Project Requirements (OPR)" criteria for system function, performance expectations, maintainability; verify and document compliance with these criteria throughout all phases of the project. Commissioning procedures require a collaborative team effort and 'should' begin during the pre-design or planning phase of the project, continue through the design and construction phases, initial occupancy phase, training of operations and maintenance (O&M) staff, and into occupancy.

Integrated project delivery (IPD) is a construction project delivery method that seeks the efficiency and involvement of all participants through all phases of design, fabrication, and construction. IPD combines ideas from integrated practice and lean construction. The objectives of IPD are to increase productivity, reduce waste, avoid time overruns, enhance final product quality, and reduce conflicts between owners, architects and contractors during construction. IPD emphasizes the use of technology to facilitate communication between the parties involved in the construction process.

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.

Operational bills are a tendering document for estimating costs prepared by architects that describes a construction project in terms of the operations needed to build it. This form of document contrasts with that of bills of quantities in which such tendering and estimation is limited to the materials in the completed work. Operational bills have the advantages of enhancing communication between design and production, enabling realistic tender pricing, and making the preparation of critical-path analysis easy for the contractor.

Capital program management software (CPMS) refers to the systems that are currently available that help building owner/operators, program managers, and construction managers, control and manage the vast amount of information that capital construction projects create. A collection, or portfolio of projects only makes this a bigger challenge. These systems go by different names: capital project management software, construction management software, project management information systems.

Pre-construction services are services that are offered to support owners, architects, and engineers in making decisions. They are used in planning a construction project before the actual construction begins. The stage where these services are offered is called pre-construction or "pre-con".

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.

<span class="mw-page-title-main">Lump sum contract</span>

A lump sum contract in construction is one type of construction contract, sometimes referred to as stipulated-sum, where a single price is quoted for an entire project based on plans and specifications and covers the entire project and the owner knows exactly how much the work will cost in advance. This type of contract requires a full and complete set of plans and specifications and includes all the indirect costs plus the profit and the contractor will receive progress payments each month minus retention. The flexibility of this contract is very minimal and changes in design or deviation from the original plans would require a change order paid by the owner. In this contract the payment is made according to the percentage of work completed. The lump sum contract is different from guaranteed maximum price in a sense that the contractor is responsible for additional costs beyond the agreed price, however, if the final price is less than the agreed price then the contractor will gain and benefit from the savings.

Early contractor involvement (ECI) is a type of construction contract where the principal contractor is engaged at an early stage in a project to offer input into the design phase. It is in contrast to the design–bid–build model where the contractor is only brought onboard at the end of the design phase. The model allows the contractor to have an input in the design of the scheme and suggest value engineering changes. Studies have shown that savings of around 10% in construction phase time and 7% in cost are achievable through the use of ECI. The ECI model has become increasingly popular in the United Kingdom since the early 2000s and is also used in Australia and New Zealand.
