Takeoffs & estimating · 13 min A plumbing estimate is counting and measuring: fixtures, connections, supply and DWV runs, fittings. Work a two bathroom rough-in by hand, then hold any software to the same rows: fixture tags, hot and cold apart, vertical runs, sticks and coils, and a written scope boundary.
Electrical · 11 min A single line diagram shows how power moves from the utility to your panels and big loads. Learn what one line means, how it differs from a three-line and a panel schedule, and how to draw one that survives review.
Permits & site plans · 13 min A site plan for permit shows your lot, existing buildings and the proposed work with measured offsets to each boundary. Here is what to include, a worked 60 x 100 ft deck example, and checklists for fences, pools, sheds, ADUs and solar.
Takeoffs & estimating · 13 min Roofing estimating software turns planes, pitch, edges and penetrations into a shingle, underlayment and metal order. Here is the math behind every line, a worked 2,000 sq ft gable at 3.5 in 12, and five checks to run before you trust any tool's total.
Permits & site plans · 13 min Deck permit drawings come down to three sheets: a site plan, a framing plan and connection details. This guide builds all three around one fictional 16 x 12 ft ledger deck, with every span, footing and guard number traced to a table you can open.
Electrical · 11 min Electrical estimating software turns plans into device counts, route lengths and a written scope. Here is how to run a takeoff you can defend, a worked route allowance example, and the one test that separates useful tools from pretty totals.
Load calcs · 11 min HVAC estimating software should trace every duct run, fitting and condenser line back to a sheet, an airflow and a dated load. Walk a worked six branch takeoff, see why per run rounding beats a blanket allowance, and get five checks for any tool.
Takeoffs & estimating · 12 min Paint estimating software earns its place when every gallon traces to a measured surface, a coat count and a spread rate from the data sheet. Work one bedroom by hand in 8 lines, then hold any app to the same rows, with prep, access and lead-safe work kept separate.
Takeoffs & estimating · 12 min A lumber takeoff lists every framing piece by size, length, count and wall. Count in a fixed order, convert to stock lengths and add one stated allowance. Worked example: a 20 x 12 ft addition needs 80 studs, 14 plate sticks and 17 sheathing panels.
