A construction site has a complex working environment. There are a multitude of suppliers and traders involved in the process and they are all working in tandem for completion of the job. Naturally, errors, mistakes and omissions are surely to be expected. And simple confusions can result in pricey reworks.
As architects and construction project engineers will vouch, reworks are the unspoken secret of construction businesses that have had a heavy bearing on completion and project costs since times immemorial.
In fact, undisclosed costs incurred due to rectification or rework amounts to almost 12 percent of the entire contract value. Therefore, the impact on revenue is significant. If you are not sure how to reduce rework in construction projects, here are some useful tips.
Address the Problem in the Design Phase Itself
You need to begin by ensuring that the constriction project models you are using are feasible. These models contain a detailing of elements needed to construct the building in their precise geometric positions. To convert a model into reality, you have to pay attention many small details. All of these should be a part of your plan, in the first place.
This is because fixing errors in a virtual site is much easier and more cost effective than having to rectify mistakes in the actual site.
Resort to Virtual Construction and Designing
VDC as well as BIM will offer a host of opportunities for detecting possible problems beforehand, preventing the wastage of time and money. Features like cost modeling, clash detection and built in scheduling help in pointing out the errors beforehand.
Conveying Information to the Site Workers
Now that you have a model your architect has finalized, you will need to convey the same to the site workers. And one of the smartest ways of doing this is by layout devices. These are tools that help tradesmen layout a project accurately. It also explains specific details much faster.
Stakeholder Involvement and Collaboration
Communication and collaboration among those connected with the project including stakeholders is important. Up front communication among interested parties will avoid possible changes and confusion.
Everyone should be on the same page for reaching an agreement. Any conflicting language or instruction should be clarified properly before the final print can be prepared.
Freezing the Design before Construction Can Start
The design has to be finalized with mutual agreement before construction can commence. No more changes should be done unless it is absolutely necessary.
Reviewing Change Orders of Past Projects
One of the best ways to learn is to review change orders from projects of the past. Studying and analyzing the causes for reworks will help in avoiding similar mistakes later.
Expert architects and construction engineers are of the opinion that a professional approach coupled with methodical work flow can minimize reworks substantially. It is all a matter of bringing in the change and reaping the benefits.
If you can follow the above tips, it would be possible for you to reduce costly reworks from on construction projects. Working with automated tools, where possible, is always a good idea, as it helps reduce the scope of manual errors.
