How many units does a long build need?
The count is set by the peak crew on site and the federal table for construction. A larger crew adds units on that scale. Heat and the length of the job add to servicing, not to the count.
Start with the peak number of workers and the crews working at the same time. A site with a crew at each end of a long building needs units at both ends, so the count follows where the workers are.
A unit that is out of service, too far away to reach in practice or unsanitary does not give the crew the facility the table counts. The count therefore carries a margin for service days and for a unit taken out of use for cleaning.
What moves the price on a long-term job?
Unit count, the length of the job, the number of moves between phases, the servicing frequency and the truck access on a site that keeps changing. The price is explained and approved before work starts.
Length is the largest factor on a long job. A unit on a pad for a year costs more to serve overall than a unit for a month, because the visits add up. Each move between phases adds a visit and needs a truck and a level pad at the new location.
A truck route clear in the first phase may be blocked by the next phase's grading or fencing. The provider confirms the price for the site before delivery, and you approve it before any work starts.
Does a long-term unit need a permit?
That depends on the jurisdiction and the work. The permitting office for the city or county confirms it before the first unit is placed.
Permits follow the jurisdiction. A site inside Austin is handled by the city, a site in Manor, Pflugerville or Buda by that city, and an unincorporated site by the county. The units are one part of the larger permit file for the build.
Right-of-way rules apply when a unit sits in a public street or on a sidewalk. A temporary use of right-of-way permit is required to close a sidewalk or driveway for work on private property, and notice to 311 is required for a planned sidewalk or lane closure.
How is the servicing schedule set?
The schedule is agreed with the site contact before the first unit is set and written into the job file, with service days, hours and an escalation contact.
The schedule has to match how the crew works. A site with an early shift needs servicing before that shift, and a site that works through a hot afternoon needs a check before the afternoon starts.
Austin summers have many triple-digit days, and a unit in the sun gets hotter and is used more on hot afternoons. The schedule can add a visit in the hottest months, and units can be shaded where the site allows.
What happens when a unit is removed?
The unit is emptied, the waste is taken to an authorized disposal facility and the pad is cleared. The removal date is set at the start of the job.
Removal is a visit like any other and needs the truck route and the pad to be open. Waste goes only to an authorized disposal facility, such as a wastewater treatment plant or a sanitary landfill.
A late removal keeps a unit on a pad the site may need for its next phase, and a rushed removal on a busy day is harder to fit into the truck route.
