The biggest thing I learned (the hard way), if you want something kept, like the existing tile tub enclosure, put that in there.  

Get Lien releases from sub/sub contractors also.Know who is on your jobsite at all times, the trades, the business names.In many places, Friday at 3 is knockoff time for Beer, make sure they are not having their tailgater parties at your jobsite.In many places work is allowed to start as soon as the sun creases over the horizon, (just after Dawn), other places have hours to construct specified.

We discovered a bum sleeping in a dumpster bin enclosure.

We're about to replace the bathtub/enclosure (est: $2,500-$3,500) in one bathroom because the bathtub have developed a crack.

And as someone who used a quad every week for work for 10 years and so has loaded one hundreds of times the lower the ramp angle the safer it is  and if you saw the presentation the ramp slides out of the tail gate and is full width so if you slip sideways your not going to run a wheel off of the skinny ramps we had to use in those days.. .. 

For exterior areas, visually inspect that bare soil within 3 feet surrounding the perimeter of a building on the property has been covered, enclosures have been installed properly and painted surfaces have been properly sealed.o Following a visual assessment, a dust sample shall be collected from a floor, and if present, window sill and window trough in no fewer and four separate rooms.

Account ClosedAfter a couple of vans and 'classic' N.A. pickups, we found a preference for the Euro-style flat-bed pickup: a flat-bed pickup (sideboards and tailgate fold down);3-way dump (dumps to the rear or to each side)has removable frame and curtains (for carrying drywall in the rain);has all-wheel drive;has crew-cab (doka) with an auxiliary heater (we plan to remove part of the rear bench to install a parts cabinet/shelf.

I got confused with the improvements I made on a rental - I paid the contractor XYZ amount (materials and labor) and he purchased the rough materials (drywall, insulation, recessed lights, bath tub, shower enclosures, paint, etc).

When all was said and done, our $12k got us:New windows throughoutInterior and exterior painting for the house and exterior painting on the garageA small amount of roofing - The house's roof was only a year old, but the cover for the back porch never got redone for some reasonGutter guards along the whole houseNew floors throughoutNew kitchen appliancesNew bathtub enclosure (including moisture-resistant drywall)Some light electrical work (new lights, flipping out receptacles, etc) What was the outcome?

You will also need to install a shower pan, a shower enclosure, and a showerhead.
