Lean Construction Advanced Project Delivery: Blinded by Convention

By Akio

Delivery of capital programs involves a complex and dynamic integration of people, organizations, and systems. Breaking the silos that exist within projects and achieving a harmonious flow of work effort that exceeds value expectations (time, cost, quality, safety, functionality, form, and delivery experience) is a commonly sought desire.

Unfortunately, unintended consequences of conventional project management approaches are the development of silos and sub‐optimization of efforts that compromise delivering what customers and stakeholders originally wanted or needed.

The moment the contracts are signed, participants (owners, designers, engineers, general contractors, design/build contractors, subcontractors, vendors, and others) set in motion forces that lessen their influence and control of the project.

* Owners want the risk of project execution to be with their designers and contractors.

* Designers and contractors cannot or will not carry all of this risk, so they transfer as much of the risk as possible to their sub‐consultants, sub‐contractors, and suppliers; and where possible back to the owner.

* Project contracts then attempt to protect each organization’s risk exposure and seek to limit interactions between parties for fear of losing control or a perceived advantage.

* Project participants are reluctant to intervene or participate in the planning, control, and management of others’ work for fear of taking back responsibility for its outcome.

* Effective working relationships have become supplanted by contract‐defined points‐of‐contact, staffing, and reporting requirements.

* Layers of contracts isolate the project participants from where project execution decisions are made. As a result, decisions and actions that affect the project value are being made with minimal visibility and/or accountability.

The contractors’ and subcontractors’ control of projects are severely compromised, and owners’ or designers’ ability to intervene on their own behalf to resolve problems or pursue improvement opportunities is greatly diminished. Fragmented decision‐making, weak collaboration and isolation of the project participants are conditions that work against addressing the complexity of today’s projects.

Even the most skillful and conscientious project managers with the most sophisticated programming tools are challenged to understand the total project information and work flow.

Without effective real‐time information exchange and work planning collaboration, each organization focuses on meeting its contract obligations with the limited information available to it. Inefficiencies, sub‐optimization and lost opportunities result from working in isolation, embedding waste in all forms and at great expense to the project.

Current project management approaches and closed systems do not address these problems. Owners who have experienced their projects running behind schedule will recall the frustration of not knowing

the precise cause of the delay or what has to be done to resolve it. Too often project participants are given inadequate, misleading, or unintentionally false information about the causes of delays to projects. Recovery plans are usually based more on hope than on rigorous analysis founded on hard data.

Because of the complex and dynamic nature of projects, we tend to blindly accept that each organization is capable of planning and executing the work they are contracted for in the most efficient and effective manner for the project. The reality is that project entities essentially act independently of each other.

The barriers that have developed have greatly diminished the ability of the Owner to influence project execution; either to resolve issues or pursue opportunities. The Owner pays significantly for the cost of embedded inefficiencies, accepts the consequences of flaws in project delivery, and hopes that retained risk can at least be contained within bloated budgets and contingencies.

This state of construction delivery is not what any rational organization should ever want. Adopting and relentlessly pursuing Lean Project Delivery is a proven approach for organizations to achieve better project outcomes.

The Advantages of Prefabrication for AEC

By Patrick

This post is part of a series of articles found in “Prefabrication and Industrialized Construction,” a Dassault Systèmes whitepaper.


Where prefabrication is possible, a number of benefits make these systems attractive to building owners.

Prefabricated systems can lead to reduced labor costs, safer projects, and fewer delays—and often results in an overall higher quality product than can be achieved with traditional stick-built projects.

Reduced Labor Costs

Prefabricated systems simplify the installation process, requiring fewer workers onsite to complete a task.

Because the most complex components are assembled in a specialized manufacturing environment, prefabrication reduces the need for skilled laborers. Skilled trade people need only be used onsite for the final connection of systems, such as wiring or ductwork.

Improved Safety

Not only does prefabrication lower labor costs, but by shortening the amount of time spent onsite, laborers are able to get in and out more safely.

so laborers are able to get in & out more safely.”

Laborers working in a controlled factory environment don’t have to brave jobsite hazards such as ice or winter chills, unsafe access to electricity, or dangerous heights. A factory-controlled environment also makes it possible to supply components and equipment where the worker needs it, rather than having workers moving parts through an active jobsite.

Minimized Delays

Sequencing for stick-built projects follows a typical pattern: each trade moves in to complete its portion of the building once the previous trade has completed its work. That means an unexpected delay in ductwork installation can push back wall framing, which then moves the schedule for the electricians who are already working around another project, and so on.

Prefabrication minimizes the need for coordination among subcontractors because electrical, ductwork, and other necessary components are installed within the wall as it’s being fabricated, requiring minimal onsite coordination.

What’s more, because the majority of work is done inside, there is no need for delays due to weather, and shift work can be performed around the clock.

Improved Quality of Finished Project

Prefabrication work is typically completed in a specialized, centralized factory. Suppliers might use a permanent location or a temporary warehouse close to the jobsite to reduce the logistics of transporting finished products.

A major advantage of working in this enclosed environment is that it allows for greater quality control than is possible on a typical jobsite. Producing these complex systems in a manufacturing environment keeps jobsite dust, dirt, and other contaminants out of sensitive systems. It allows for more oversight of each step of the process.

Once completed systems arrive onsite, surveying devices such as transits help installers to precisely locate where each component needs to be installed. Expert tradesmen must simply connect the final pieces.

Expanding Benefits

While not every project—or every system within a project—may be able to take advantage of prefabrication, today’s new technology allows even highly custom systems to take advantage of these benefits to workers and building owners.
