How to Eliminate Construction Defects with a Simple Document
It’s finally here! We recently completed our final draft of a technical specification for Quality Assurance Observation. We believe this allows us to effectively and easily help projects deliver quality simply by inserting this section into their Specs. Architects like it because it protects them from dealing with construction defects; they are adding value for the ownership team. Contractors know up front what the expectations are and how the process will work – same goes for subs. It’s a win-win-win-win. We deliver a quality structure that has exponentially reduced the risk of going to litigation for a construction defect claim. [...]
5 Step Process to effectively mitigate poor quality construction
Over the last 5 years we've been creating, implementing, tweaking, and perfecting the QAO methodology to help contractors, architects, subcontractors, insurance professionals, and even banks effectively mitigate poor quality construction. We continue to gather feedback and improve our process. While we don’t say we have the “only” solution or even that we have a “silver bullet” to solving every potential problem, the QAO process we do have has proven to be simple, effective, and profitable. So what is our 5-Step process to effectively mitigate poor quality construction? Step 1 – Become a Certified Quality Assurance Practitioner (CQAP); send someone to [...]
What is the #1 Important Trigger for Green Builders?
Just finished looking over the Mcgraw-Hill Residential Green Home Bldg Survey and was taken aback by a few slides and statistics. I’m sure many of you have already seen this report as it’s been out for a few months, we were recently pointed to it by our colleague Brian Hill. The number one trigger for green builders is higher quality! What processes are imposed during the green building process which ensures higher quality? Is there required QA for all green buildings? Are there points for quality in the LEED scoring system? None (which we’re aware of) that have anything to [...]
