Business Organization and Management

  • Mississippi LLCs are formed by filing a certificate of formation with the Secretary of State; a foreign LLC must file a certificate of authority before doing business in the state.

  • Sole proprietorships and general partnerships expose owners to unlimited personal liability; LLCs and corporations generally shield owners from business debts.

  • Working capital = current assets − current liabilities; it measures the cash and near-cash resources available to fund short-term operations.

  • Current ratio = current assets ÷ current liabilities; quick ratio = (cash + marketable securities + receivables) ÷ current liabilities.

  • Debt-to-equity = total liabilities ÷ owners' equity; a rising ratio signals greater reliance on borrowed funds and reduced bonding capacity.

  • Mississippi employers generally must carry workers' compensation insurance when they have five or more employees; sole proprietors and partners may elect coverage.

  • Mississippi unemployment tax liability begins after paying $1,500 in wages in a calendar quarter or employing one or more workers for 20 weeks in a calendar year.

  • Contractors are generally consumers of construction materials in Mississippi, so they pay sales tax on materials and do not collect sales tax on the installed improvement.

  • A municipal or county privilege license may be required in addition to the state contractor license; local business licenses do not replace the MSBOC license.

Contract Administration

  • A change order must be in writing and signed by the owner and contractor; oral directives should be confirmed in writing before performing extra work.

  • Liquidated damages must be a reasonable forecast of probable loss at contract formation; a clause that punishes the contractor is unenforceable as a penalty.

  • Substantial completion is the stage when the work is usable for its intended purpose, even if punch-list items remain; final completion follows correction of all punch-list items.

  • Type I differing site condition: subsurface conditions differ materially from those indicated in the contract documents; Type II: conditions differ from those ordinarily encountered.

  • Notice provisions are conditions precedent in many contracts; late written notice can bar an otherwise valid delay or change claim.

  • A pay-when-paid clause generally sets timing of payment; a pay-if-paid clause can make owner payment a condition precedent to subcontractor payment, depending on state law.

  • Under the federal Miller Act, a subcontractor on a federal public project must give written notice within 90 days after last furnishing labor or materials and sue on the payment bond within one year.

  • Retainage is a percentage withheld from progress payments to ensure completion; it reduces contractor cash flow and is released after substantial or final completion per contract.

  • Termination for convenience allows the owner to stop work without cause, typically paying for work performed, reasonable closeout costs, and profit on completed work.

Licensing Law, and Lien Law

  • Mississippi requires a Certificate of Responsibility for construction contracts of $50,000 or more; the license is issued by the Mississippi State Board of Contractors.

  • Public bid envelopes for Mississippi projects over $50,000 must display the contractor's Certificate of Responsibility number on the outside; bids without it can be rejected.

  • Unlicensed contracting above the threshold can render the contract unenforceable and subject the contractor to penalties; licensing is generally a prerequisite to sue for the contract price.

  • A qualifying party is the individual who passes the MSBOC examination and is responsible for the contractor's operations; the license is issued to the business entity.

  • A mechanics' lien claimant must file a notice of lien with the chancery clerk of the county where the property is located within 90 days after last furnishing labor or materials.

  • An action to enforce a Mississippi mechanics' lien must generally be filed within 12 months after the lien is filed, or the lien expires.

  • No mechanics' lien attaches to public property; unpaid subcontractors on public projects look to the payment bond, not a lien.

  • Conditional lien waivers take effect only when payment is received; unconditional waivers are effective on signing and should be limited to the amount paid.

  • A lien waiver is not a release of rights for disputed or unpaid amounts unless the waiver expressly says so.

Project Management, Scheduling, and Supervision

  • Critical path is the longest continuous path through the network; activities on it have zero total float and control project duration.

  • Total float = late start − early start, or late finish − early finish; free float = early start of successor − early finish of activity.

  • PERT expected duration = (optimistic + 4 × most likely + pessimistic) ÷ 6.

  • Crashing shortens duration by adding resources to critical activities; choose the activity with the lowest crash cost per day first.

  • Fast-tracking overlaps design or construction phases to compress schedule; it increases coordination risk and change potential.

  • Resource leveling shifts activities within available float to smooth resource peaks; it can consume float and change the critical path.

  • A three-week look-ahead schedule identifies upcoming activities, constraints, and required resources; it is updated weekly.

  • Daily reports should record weather, crew counts, equipment, deliveries, visitors, delays, and verbal directives; they are contemporaneous evidence.

  • RFI log tracks questions and responses; unresolved RFIs can justify delay if they affect critical-path work.

Estimating, Bidding, Plans, and Specifications

  • Concrete volume in cubic yards = length (ft) × width (ft) × depth (ft) ÷ 27.

  • Roofing quantity: one square = 100 square feet; divide roof area by 100 to get squares.

  • Board feet = thickness (in) × width (in) × length (ft) ÷ 12.

  • Markup on cost = (price − cost) ÷ cost; gross margin = (price − cost) ÷ price; price = cost ÷ (1 − desired margin).

  • Bid bond typically equals 5% to 10% of the bid; performance and payment bonds typically equal 100% of the contract price.

  • Addenda are written changes issued before bid opening; bidders must acknowledge each addendum on the bid form.

  • CSI MasterFormat Division 01 covers general requirements such as submittals, temporary facilities, and closeout.

  • Unit-price bid total = estimated quantity × unit price; actual payment is based on measured quantities.

  • Contingency in a conceptual estimate is commonly 5% to 10% for design-bid-build and higher for early schematic estimates.

Construction Safety and Risk Management

  • OSHA construction fall protection is required at 6 feet above a lower level for general construction; scaffolds trigger at 10 feet and steel erection at 15 feet.

  • Excavations 5 feet or deeper require a protective system unless a competent person determines stable rock; access/egress is required every 25 feet.

  • Spoil piles and equipment must be kept at least 2 feet from the excavation edge; the competent person inspects daily and after rain.

  • Scaffolds require a 4:1 height-to-base ratio, fully planked work platforms, guardrails, and competent-person inspections.

  • Permit-required confined spaces require atmospheric testing, an attendant, ventilation or respiratory protection, and a rescue plan.

  • Hazard Communication requires safety data sheets, labeled containers, and worker training on chemical hazards.

  • Risk treatment options are avoid, reduce, transfer (insurance/bonds), and retain; safety programs primarily reduce frequency and severity.

  • Mississippi workers' compensation covers employees injured on the job; the exclusive remedy generally bars employee tort suits against the employer.

  • Crane operations require a load chart, qualified operator, signal person, and barricaded swing radius.

Financial Management

  • Balance sheet reports assets, liabilities, and equity at a point in time; income statement reports revenue and expenses over a period.

  • Percentage-of-completion revenue = total contract price × (costs incurred ÷ total estimated costs).

  • Underbillings (costs and estimated earnings in excess of billings) are an asset; overbillings are a liability.

  • Break-even revenue = fixed costs ÷ contribution margin ratio, where contribution margin ratio = (revenue − variable costs) ÷ revenue.

  • Gross profit margin = (revenue − cost of goods sold) ÷ revenue; net profit margin = net income ÷ revenue.

  • Cash flow is not the same as profit; construction typically requires cash outlays for labor and materials before progress payments arrive.

  • Aging accounts receivable measures how long invoices remain unpaid; slow collections increase borrowing needs and can impair surety capacity.

  • Sureties evaluate working capital, net worth, liquidity, debt, backlog, and completed-project history when setting bonding capacity.

  • Equipment ownership costs include depreciation, interest, insurance, and taxes; operating costs include fuel, repairs, and tires.

Labor, and Environmental Compliance

  • Davis-Bacon requires prevailing wages on federal construction contracts over $2,000; contractors submit certified payrolls weekly.

  • FLSA child labor rules limit 14- and 15-year-olds' hours and prohibit hazardous occupations for workers under 18.

  • Mississippi employers with five or more employees must use E-Verify to confirm employment eligibility under the Mississippi Employment Protection Act.

  • OSHA injury and illness logs (Form 300) are required for most construction employers, but establishments with 10 or fewer employees are exempt from routine logkeeping.

  • NPDES Construction General Permit applies to land disturbance of one acre or more; a Stormwater Pollution Prevention Plan (SWPPP) and inspections are required.

  • Stormwater controls include silt fence, sediment basins, stabilized construction entrances, and immediate seeding or mulching of disturbed areas.

  • NESHAP requires an asbestos survey before renovation or demolition of a facility; regulated asbestos-containing material must be removed by trained workers.

  • EPA's Renovation, Repair and Painting rule requires lead-safe certified firms and workers for renovation of pre-1978 housing and child-occupied facilities.

  • Section 404 of the Clean Water Act requires a U.S. Army Corps of Engineers permit before dredging or filling wetlands.
