Modules

Stand-alone modules, each a complete report.

Three modules that do a whole job on their own, in your browser or in the desktop app: the electrical one-line, the Florida product approval form, and the retaining wall. Each one ties to the project's address and site conditions like everything else in PerCode.

One-Line (NEC)

The electrical one-line, panel schedules and load calculations from one model.

Describe the site as a distribution tree — structures, panels, feeders and circuits — and every deliverable is drawn from that one tree, so the riser, the schedules and the load calculation cannot disagree.

  • Load calculation per structure by the NEC 220.82 optional method and the Part III standard method, the larger governing; an existing panel can be entered as a measured 220.87 demand.
  • Every feeder and service designed: conductors, overcurrent protection, grounding conductor, raceway and fill, burial depth and voltage drop.
  • More than one unit on a service — a house with an accessory unit, a duplex — and non-dwelling sites such as an event lot, a garage or a stand, with the separate-structure grounding rules.
  • The permit drawing: a one-line riser, a schedule per panel, plan notes, a PDF report and a DXF in the module's own or NECA 100 symbols.

Limits. NEC 2023, or NEC 2020 where the state adopts it. Single-phase 120/240 V or 120/208 V, one supply per panel. It does not size transformers, and solar, storage and generators are not scheduled as loads.

Florida Product Approval

The product approval form the building department asks for, checked first.

Our best tool for builders, architects and anyone pulling a Florida permit. Cite each window, door, shutter, roof or cladding product by its Florida approval (FL#) or Miami-Dade NOA number, pick the jurisdiction, and it checks every product against the State's and Miami-Dade's approval records before it fills the form.

  • Eight determinations per product: the number resolves, the approval is in force on the permit date, it is approved rather than a pending application, the category and jurisdiction match, and the rated pressure covers the required one.
  • The product approval form for the jurisdiction you pick, with a supporting PDF that shows each determination and the record it came from.
  • The High-Velocity Hurricane Zone rules where the site's county is in it.

Limits. Design pressures are an input — it does not compute wind pressures, select products for you, or design a roof assembly.

Retaining Wall

Cantilever, gravity and masonry retaining walls to ACI 318.

Four stem types in one module: reinforced concrete (uniform or battered), plain-concrete gravity, reinforced CMU, and a CMU stem on a concrete base.

  • Stability: overturning, sliding, soil bearing and eccentricity.
  • Stem and footing design: flexure and shear at the heights you choose, toe and heel, minimum and shrinkage reinforcement, development lengths and crack control.
  • Loads: earth pressure by equivalent fluid, Rankine, Coulomb or at-rest; uniform and strip surcharges; wind on an exposed stem; a seismic increment by Mononobe-Okabe.
  • Drawings of the cross-section and the pressure diagrams in the report.

Limits. ACI 318-25 with ASCE 7-22. Masonry stems are fully grouted only; a plain concrete stem needs a separate reinforced footing and Seismic Design Category A, B or C. Segmental and MSE walls are not covered.
