NV General Contractor cheat sheet

Working capital = current assets - current liabilities; it measures the funds available to meet near-term obligations.

Current ratio = current assets / current liabilities; a value below 1.0 indicates current liabilities exceed current assets.

Quick ratio = (cash + marketable securities + receivables) / current liabilities; inventory and prepaid items are excluded.

Gross profit = revenue - direct job costs; gross profit margin = gross profit / revenue.

Break-even revenue = fixed overhead / gross margin percentage; this is the revenue at which overhead is exactly covered.

Overhead allocation rate = total indirect overhead / selected direct cost base, such as direct labor dollars or direct labor hours.

Retainage is a percentage withheld from progress payments until completion or acceptance; it reduces cash received during the job.

Profit and cash flow differ: a profitable project can have negative cash flow because of retainage, slow payments, or front-loaded costs.

The Nevada State Contractors Board administers contractor licensing, investigates complaints, and enforces NRS 624 and NAC 624.

A qualifying party must meet experience requirements, pass the required examination, and be responsible for the licensee's construction work.

Nevada contractor licenses include Class A general engineering, Class B general building, and Class C specialty classifications.

The NSCB sets a licensee's monetary limit based on demonstrated financial responsibility; work may not be bid or contracted above that limit.

A contractor license bond and workers' compensation coverage are conditions of active licensure unless an exemption applies.

Contractor license numbers must appear in contracts, bids, and advertising so the public can verify licensure with the NSCB.

A licensee must notify the NSCB of changes in ownership, qualifying party, business address, or financial condition as required by regulation.

Unlicensed contracting is prohibited and may result in NSCB citations, administrative penalties, stop-work orders, or referral for prosecution.

A quantity takeoff measures materials and labor quantities from plans and specifications before unit prices are applied.

Labor cost = labor hours x wage rate x labor burden factor; burden includes payroll taxes, insurance, benefits, and paid time off.

Material cost estimate = net quantity x unit price x (1 + waste factor); waste varies by material and installation method.

Total float = late start - early start = late finish - early finish; critical-path activities have zero total float.

Cost Performance Index (CPI) = earned value / actual cost; CPI below 1.0 indicates cost overrun for work performed.

Schedule Performance Index (SPI) = earned value / planned value; SPI below 1.0 indicates work is behind schedule.

A change order must be written and authorized before performing changed work to preserve entitlement to payment and time.

A punch list records incomplete or defective work that must be corrected before final acceptance and final payment.

OSHA construction focus four hazards are falls, struck-by, caught-in or between, and electrical hazards.

OSHA generally requires fall protection at 6 feet for construction work; scaffold fall protection is required above 10 feet.

Excavations 5 feet or deeper require a protective system unless the excavation is entirely in stable rock.

Trenches 4 feet or deeper require a ladder, stair, or ramp so lateral travel to an exit is no more than 25 feet.

The Hazard Communication Standard requires chemical labels and Safety Data Sheets for hazardous chemicals on site.

Respirable crystalline silica controls include wet cutting, dust collection, ventilation, work practices, and respirators when needed.

A Stormwater Pollution Prevention Plan describes erosion, sediment, and pollution controls for construction stormwater discharges.

Nevada NDEP administers stormwater and environmental permits; concrete washout and fuel storage must be managed to prevent releases.
