Agile construction is a method or style of building that can quickly adapt to changes in delivery or designs. The method reduces the time between identification of a problem and resolving the problem.
At first glance, Agile construction methods and management might look like an odd couple. After all, the Agile development— that made its name in the automotive and software industry—revolves around constantly checking and adapting the deliverables to changes in the market. One would not think construction projects can be changed as one would change a software.
Without the same constraints as physical buildings (there is no gravity inside computers, for example), the software can be built up and built out with considerable flexibility. Buildings must still follow more rigid procedures, like only building the third floor once the second floor is sufficiently solid. However, Agile construction management can still offer benefits in construction, when used appropriately.
Building on the Agile Model
To understand what to do with it, we need to know some basics about Agile project management.
- Alignment of the project deliverables to customer requirements
- Definition of clear goals for a project
- Breaks the project or challenge down into small bits to be completed in order of highest priority downwards
- Continual reviews of progress and improvement from those reviews then applied to the project
- A clear definition of when a task or activity in the project has been done
- Development of team intelligence and know-how through teamwork and collaboration across different parts of the project
So far, so good. All of these characteristics can be advantageously applied to Agile project management in construction too.
A Bit of Agile That Cannot Be Used
There is one other Agile characteristic that does not carry over. In Agile project management applied to software, it is possible to put off a major design decision or step to a late stage in project execution. For construction, however, this is unlikely to work. In construction, the execution phase is largely linear, with one step needing to be completed before the following step can be taken.
Agile Construction in the Pre-Design and Design Phases
Agile construction management can be most impactful and provide benefits in the design and pre-design phase of a construction project. It can increase customer involvement, encouraging customer participation in project deliverable definition (i.e. what the finished building or construction will be).
Agile construction allows complex projects to be broken up into easier to manage subprojects. Smaller projects reduce the chance of uncertainty and improve the management of project risks. This division allows for increased accuracy and confidence in construction cost estimating.
Agile construction makes greater use of prefabricated assemblies. Prefabricated elements make the projects more like manufacturing projects where unpredictable factors like the weather or labor availability have less effect.
Agile Construction Management in the Execution Phase
While construction, because of its sequential step-based nature, ought to be simple enough in practice, complexity can still creep in. A contractor may need to use different materials for instance because the ones specified by the architect are unavailable at that time. Also, access to a site or to resources may be blocked, adding to the problems.
Construction tasks are then often handled using improvisation and, as a result, it becomes difficult to track project schedules and manage critical path activities. Agile construction management helps by breaking down the project delivery into smaller, more manageable, parts.
One primary focus is on time management and regular. Agile requires frequent reviews to improve project financial management, specifically in the areas of productivity and profitability.
Another unusual aspect of Agile methods is that it opens the door to continual improvement by encouraging workers to team up and to give their input back to construction managers. This hands-on input provides insight on how to do things better and faster.
The Increasing Role of Software in Construction
Not only did Agile approaches spring from software and automotive development, but the software itself has become a useful and necessary tool for many construction projects. Agile software and its benefits include:
- Construction project management programs with team collaboration
- Customer relationship management software to help get customers and stakeholders of all kinds involved
- Construction cost estimating software
So overall, Agile can be applied to construction management—and it’s effective in getting the job done. While Lean construction continues to be popular, expect more construction firms to start implementing Agile construction as the years roll on.
