Drainage checks for Austin site plans, before the City reviewer.

Bolteniq reads the drainage tables in a City of Austin site-plan set and runs two dozen checks against the DCM, ECM and LDC. It flags arithmetic and consistency errors. You confirm every value. Your PE stays the engineer of record.

Austin review is long, and some of it is arithmetic

From the City's own comment reports on 85 recent Austin site plans, public on AB+C.

4resubmittals for the median plan after the City's first review. Nearly 4 in 10 took 5 or more.
9 weeksmedian from one City comment report to the next, redesign and resubmittal included.
13 of 32sampled plans got at least one comment in the first review about a calculation that did not check out or numbers that disagreed.

Those are the comments Bolteniq is built to catch before you submit: the plan above is one where the City asked for the R-3 and drawdown calculations to be rechecked.

What it does with a plan set

Reads the drainage tables

Drainage areas, Tc, peak flows, ponds, R-3, R-6 and R-11 forms, pipes and inlets. Each value sits next to the sheet it came from.

Runs two dozen checks

Against the City of Austin DCM, ECM and LDC. Each finding names the rule it is based on and the printed values it points at.

Leaves the decisions to you

You confirm or correct every value. It does not design anything.

We pull one of your recent approved Austin site plans from AB+C ourselves, run it, and send you what it flags, next to the comments the City made on that plan. You don't need to send anything.
