Tips to Minimize Contractor Change Orders When Remodeling

Performance Tip #1 – Contractor Delays
When a trade gets behind in his work, it not only impacts the schedule but it also impacts all the trades that follow his work.
If the trades that follow are then required to accelerate their work to maintain your schedule, they can incur overtime costs that they will seek to recover through a change order for a cause not of their making.
Contractors or trades who fall behind in their scope (and not due to you as the owner or to project impacts outside their control) should have the understanding upfront that they will be required to take necessary action to meet and maintain your job progress, without additional compensation. Any costs associated with accelerating work, if required to meet schedule, then becomes an issue handled between the contractor and his trades.
Performance Tip #2 – Material Delivery Commitments
Change orders in construction often occur when the contractor fails to timely secure orders for materials. The contractor, as a best practice, needs to timely secure delivery commitments, place orders for materials, equipment and services required in connection with the Work to avoid delays and maintain the scheduled timeline.
Often contractors will wait to order materials until just before the time they are due for scheduled installation. Many times they will find out that particular item is no longer in stock or unavailable, resulting in a potential schedule impact. This happens frequently when a contractor does not have the storage capacity for items ordered early and does not want to pay for storage.
There are also many instances where a specified product or material becomes discontinued and that can be a schedule impact if a new alternate product needs to be selected and approved. Selecting a new product and/or taking a late delivery impacts the schedule, the overall work flow and can result in change order requests.
Discuss with the contractor, in advance, any items on your project which he may see as a potential delay so alternatives can be discussed or substitutions selected.
Performance Tip #3 – Drawing Dimensions vs. Field Measurements
Change orders in construction generally occur when dimensions provided on contract drawings have not been field verified.
Drawing dimensions rarely correlate to actual field conditions which is why measurements should always be field verified. The contractor and his trades need to be responsible for taking necessary field measurements before fabricating materials to ensure the work will fit and function properly with other work.
It is not uncommon to have actual field dimensions off by not only inches but feet which can impact the integration of any work that follows. Improper measurements or failure to field measure can result in potentially costly rework and schedule impacts.
Avoid change orders for this condition by making it their responsibility to field measure in your contract language.
Performance Tip #4 – No Substitutions Allowed
If your contract drawings call for specified product, model, color, serial number, manufacturer, or series, then the contractor is contractually obligated …
