WOC 2014 Polishing Luncheon
Theme – No good deed should go unpaid; how to set accurate bids; and get paid for work that wasn’t in the contract documents.
Concrete polishing contractors face the difficult challenge of transforming someone else’s work into a finished project that requires final owner approval. As the concrete polishing matures, contractors are adapting new technologies and business practices to eliminate the uncertainty that often comes in preparing a bid for a project.
These innovations include methods that help contractors better inspect job site conditions prior to polishing; collect job site work performance data including bit wear and energy usage; and analyze work performance as compared to job site conditions.
Topics will include:
• Calculating a bid price based on past field experience.
Polishing contractors will learn how they can collect, use, and share field operating data. By establishing objective parameters contractors can create a "library" or repository of true data. Items that could be collected include regional concrete mix designs, concrete surface strength using the rebound method, process-specific information such as abrasives used, diamond wear, how many passes it takes to reach a level of refinement, etc.
The presentation will include an update of industry specific products developed by manufacturers that collect polishing specific measurement and software that make field experience data collection easy.
• Using technology to better assess the job
Prior to polishing contractors should perform a pre-job survey to assess surface defects, jointing problems, and other potential problems not mentioned in the job specifications. Contractors can also perform some simple nondestructive tests on the slab that can help predict how the job will go. These tests include measuring surface strength, flatness, and trueness to specification.
A contractor or a contractor’s estimator who can describe how they go about putting together a bid and what they look for at the jobsite in terms of “booby traps” or potential unknowns that can increase costs.
• How to recover costs from unexpected jobsite conditions
Owners don’t like to hear about job site problems that cost them money. They don’t want to hear about excessive curling, wavy floors, and pre-poured concrete that doesn’t meet specs.
Learn how to combine the facts from your job site library and your pre-project survey and field experience data to recover your expenses for jobsite problems that weren’t yours in the making.
