44 cards. Read the term and the definition here. The deck at the top of this page is optional.

Critical path definition

The longest duration sequence of dependent activities through a project network. Its total float is zero, so any delay on it shifts project completion by the same number of days.

Total float formula

Late start minus early start, or late finish minus early finish. It is the time an activity can slip without delaying the project completion date.

Cost performance index

Earned value divided by actual cost. A value below 1.0 means the work performed cost more than budgeted; above 1.0 means under budget at that point.

Schedule performance index

Earned value divided by planned value. A value below 1.0 indicates the project is behind the planned schedule progress at the measurement date.

Estimate at completion by CPI

Budget at completion divided by the cost performance index. This forecast assumes remaining work continues at the same cost efficiency observed to date.

Percent plan complete

Completed commitments divided by total commitments made in the weekly work plan. It measures short-interval planning reliability rather than physical progress alone.

Labor burden rate

The percentage added to base wages for payroll taxes, insurance, and benefits, commonly 25 to 40 percent. Burdened rates must be used in all cost comparisons.

Margin versus markup

Markup is added to cost as a percentage of cost. Margin is a percentage of selling price, so price equals cost divided by one minus the margin.

Learning curve effect

Repetitive operations improve roughly 10 to 20 percent per doubling of units until reaching a plateau. First-unit rates should not be applied to total quantity.

Fall protection trigger height

In general construction, fall protection is required at 6 feet or more above a lower level. General industry work uses a 4-foot trigger height.

Excavation protective system threshold

Excavations 5 feet or deeper require a protective system such as sloping, shoring, or shielding. A competent person must classify soil and inspect daily.

Excavation egress distance

In trenches 4 feet or deeper, a means of egress such as a ladder must be within 25 feet of lateral travel for every worker in the excavation.

Spoil pile setback

Excavated material, equipment, and supplies must be kept at least 2 feet back from the edge of an excavation to reduce surcharge and collapse risk.

Extension ladder slope

Extension ladders are set at a 4-to-1 ratio, meaning 1 foot of base setback for every 4 feet of working height, with 3 feet extending above the landing.

Hazard control hierarchy

Controls ranked from most to least effective: elimination, substitution, engineering controls, administrative controls, and personal protective equipment as the last line of defense.

Hearing protection threshold

Hearing protection is required when noise exposure reaches an 8-hour time-weighted average of 85 decibels, with a monitoring and training program in place.

Lockout tagout verification

Each worker applies a personal lock, then verifies zero energy by attempting start-up or testing. Only the worker who applied a lock may remove it.

Guardrail height standard

Top rail is 42 inches plus or minus 3 inches above the walking surface, with a midrail at approximately 21 inches and a toe board where required.

Concrete cylinder specification

Standard test cylinder is 6 inches diameter by 12 inches tall, cured and tested at 28 days. Cylinder strength is roughly 0.8 times cube strength.

Water-cement ratio effect

Lower water-cement ratio increases strength and reduces permeability. Each 0.01 reduction typically adds roughly 250 to 400 psi of 28-day strength.

Footing area calculation

Footing area equals total load divided by allowable soil bearing pressure. Typical allowable values are 1,500 psf for firm clay and 3,000 psf for compacted granular soil.

Minimum drainage slope

Site grading and flat roofs drain at a minimum of 1/4 inch per foot, which is 2 percent, directing water away from structures and ponding areas.

Rebar tension lap splice

For Grade 60 reinforcement in normal-weight concrete, a tension lap splice is typically 40 bar diameters, with a standard hook extending 12 bar diameters.

W-shape designation meaning

A W12x26 is a wide-flange beam with nominal depth 12 inches and weight 26 pounds per linear foot. Weight, not depth, uniquely identifies the section.

Nominal versus dressed lumber

Dressed lumber is smaller than nominal size: a 2x4 measures 1-1/2 by 3-1/2 inches, and a 2x10 measures 1-1/2 by 9-1/4 inches.

Typical span of control

A working foreperson effectively supervises about 5 to 12 workers. Beyond that range, add a lead or split the crew by task area.

Progressive discipline sequence

Steps run from verbal coaching to written warning, suspension, and termination. Each step requires a dated record of behavior, expectation, and consequence.

Toolbox talk standard

A 10- to 15-minute hazard briefing at the start of shift, focused on that day's tasks, with each attending worker signing the attendance record.

Delegation confirmation rule

Assign by result and deadline, then ask the worker to restate the task to confirm understanding. Check at agreed milestones rather than continuously.

First-inspection quality control

The first unit of repetitive work is inspected and approved against the specification before production continues, preventing repeated defects across the run.

Hold point definition

A stage in the inspection and test plan where work cannot proceed until the required check is performed and signed off by the designated party.

Change order required content

A change order states the scope change, price adjustment, time impact, and resulting schedule adjustment, and requires written authorization before work proceeds.

Nonconformance report content

It records location, requirement, actual condition, disposition such as rework, repair, concession, or reject, and verification that the corrective action closed the item.

Submittal review statuses

Return statuses are approved, approved as noted, revise and resubmit, and rejected. Installation may not begin until an approved or approved-as-noted status is issued.

Substantial completion effect

Substantial completion starts warranty periods, allows owner occupancy, and typically releases part of retainage, while a deficiency list remains to be corrected.

Document order of precedence

The agreement usually governs first, then addenda, specifications, and drawings, with standard conditions last. The more stringent requirement generally controls conflicts.

Shop drawing definition

Contractor-prepared details showing fabrication and installation. Designer review confirms general conformance only and does not relieve the contractor of contract compliance.

Daily site report content

It records date, weather, temperatures, crew counts by trade, equipment, work performed, deliveries, visitors, delays, and instructions received that day.

Written notice of claim

Most contracts require notice of a claim within a set number of days after the triggering event. Late notice can bar an otherwise valid claim.

Punch list item standard

Each entry must state location, specific description, responsible trade, and target date. Vague entries cause disputes at final acceptance and delay closeout.

Performance documentation standard

Record observable behavior and outcome rather than personality, including date, time, location, witnesses, and the specific standard that was not met.

Shift handover log

A written record of open work, hazards, equipment status, and pending inspections, signed by both outgoing and incoming forepersons at shift change.

Cross-training matrix purpose

It maps workers to tasks with proficiency levels, revealing single-point skill dependencies that could stall production if one worker is absent.

Crew meeting minute timing

Minutes circulated within 24 hours create a contemporaneous record of assignments and commitments that later supports schedule and claim positions.
