Osprey Constructors, LLC

According to the manufacturer, the whole operation should not have taken more than a couple weeks.  It has taken six months.
The contractor rarely came out himself and left all work to his minions and subcontractors.
There were problems at every step of the way, most of them resulting from inexperienced people working without supervision.
* Two crews and one independent subcontractor were involved with pouring the slab.  The footings got washed out a couple times and there was a lot of re-digging of trenches.  The resulting footings were a few inches off square, and used far more concrete than required.  The slab was poured on a rainy day.  They kinda lost control of the job.  I ended out having to run to the hardware to buy visquine to keep the rain off.  I was promised a light broom finished and a slightly crested slab.  I got a complicated, rain-pocked slab that required treatment with a hardener. 
* The first subcontractor to work on erecting the building didn't realize that there were two different types of arched pieces and mixed them up.  They then beat on things to try to make them fit . . . without success.  This destroyed materials.  There was a delay when new materials were ordered.  
* The Contractor's own crew then tried to assemble the building, but they, too, didn't realize that there were different types of arched pieces.  They couldn't get past panel five of 20.  
* The Contractor brought in someone with prior experience erecting arched steel buildings and construction.  This guy figured out what was wrong and erected 11 of 20 panels with no problems, but then ran out of materials.  This resulted in conflict between the Contractor and the arched building guy.  The Contractor wanted to doc the guy's pay because the original order for replacement parts didn't correctly predict what was needed to finish the building.  They didn't have formal contracts and there was and still is much disagreement about who is responsible for what.
* Another order went out for replacement materials.  These are not stock items, and it took about two months for a factory run and for load consolidation in shipping.  Once parts arrived, the building erection has gone fairly smoothly.
* When the building was up and things dried out it became apparent that the slab was soft and crumbly, and generating an alarming amount of dust.  Negotiation has been required to get a concrete specialist out to prep the floor and apply a commercial hardener to fix the surface problems (apparently the result of rain during the pour).
*The erected building failed its first final inspection because the contractor's employees had opted not to install the brackets to secure the building to the foundation.  The contractor explicitly billed me for the anchors to install these brackets.  Further negotiation was required to get these brackets installed.  This is FLORIDA, and, yes, inspectors are going to be alert to any foundation anchoring that might compromise the building's hurricane strength, especially given these are specified on the engineered plans.
*Although Adam Brang stated that he had filed a notice of termination with the county, county records do not show this a month after he received final payment.  The effect of this is that he has a lien on my title and I cannot use my property as collateral on a loan.
Negotiating with Osprey has been unpleasant.  Early in the job, the Contractor accused me of liable for telling the plumber that there had been some delays in construction so he would have to come out a few days later than originally stated.  A month into the work they sent a notice saying that they had a legal right to put a lien on my property if I didn't pay up.  Such notification is supposed to be in the original contract for work and needs to be signed by the Contractee.  Since then, communication has been stiff.  
 
The only good thing I can say is that Osprey has been fairly responsible about fixing mistakes, though the process has cost them many thousands of dollars and wasted an enormous amount of time.
