The 31 NASCLA procurement questions: where the points are
Procurement and Contracting Requirements is the largest subject area on the NASCLA Commercial General Building exam: 31 of the 115 scored questions, about 27%. That is more than Site Construction, Concrete and Masonry put together. It is also the area where a good field superintendent can lose the most points, because much of it is office work: bids, contracts, bonds, money and payroll. This post breaks it into parts, works the arithmetic and points to the listed books. To see your score in this area before you start, take the free 10-question check.
What the bulletin says, and what it does not
PSI's Candidate Information Bulletin (updated 7 Jul 2026) gives the area name and its 31 questions, and nothing below that. There is no topic list. The breakdown below is our reading of the area name and the listed references, not a NASCLA list, and no single topic is promised to appear.
Check the share: 31 / 115 = 0.2696, about 27%. And Site Construction, Concrete and Masonry are 15 + 6 + 4 = 25, six fewer than 31.

The parts of the area
Bidding and the bid package
Invitations to bid, instructions to bidders, bid forms, addenda, bid security, and the difference between a responsive bid (it follows the instructions and form) and a responsible bidder (able to do the work). See reading a bid package like an examiner.
Estimating, markup and margin
Quantity takeoff, unit prices, labor productivity and burden, overhead and profit. This is where arithmetic questions cluster, and where the most common trap sits.
Worked example (invented). Direct cost is $250,000.
- A 20% markup on cost: price = 250,000 x 1.20 = $300,000. Profit is $50,000, which is a margin of 50,000 / 300,000 = 16.67% of price. Check: 0.20 / 1.20 = 0.1667.
- A 20% margin on price: price = 250,000 / 0.80 = $312,500. Check: 312,500 x 0.80 = 250,000, and the profit of 62,500 is 20% of 312,500.
Confusing the two costs $12,500 here (312,500 - 300,000). More in five estimating mistakes that cost points and money.
Bonds and insurance
The three parties to a surety bond (principal, obligee, surety), what bid, performance and payment bonds each protect, and why a bond is not insurance for the contractor. Insurance types such as general liability, builder's risk and workers' compensation sit next to it.
Contracts and project delivery
Lump sum, unit price, and cost plus a fee with or without a capped maximum price (GMP); design-bid-build, design-build and construction management delivery; general and supplementary conditions; and who carries which risk.
Changes, payment, retainage and liens
Change orders and change directives, pay applications, retainage and lien basics.
Worked example (invented). A pay application shows $120,000 of work completed this period, and the contract holds 10% retainage. Retained: 120,000 x 0.10 = $12,000. Paid this period: 120,000 - 12,000 = $108,000. Check: 120,000 x 0.90 = 108,000.
Liens differ by state. Notice rules, deadlines and who may file are set by each state, and the exam is used in many states. Learn the concepts (what a lien is, why notices and waivers exist, how a payment bond relates to public work) and do not carry one state's deadlines into an exam answer.
Business organization and financial statements
Sole proprietorships, partnerships, corporations and LLCs; the balance sheet and income statement; and ratios such as the current ratio.
Worked example (invented). Current assets $540,000, current liabilities $360,000. Current ratio = 540,000 / 360,000 = 1.5. Check: 360,000 x 1.5 = 540,000.
Break-even and depreciation
Straight-line depreciation (invented). A truck costs $68,000 with an $8,000 salvage value over 5 years. Annual depreciation = (68,000 - 8,000) / 5 = $12,000. Check: 12,000 x 5 = 60,000, plus 8,000 salvage = 68,000.
Payroll, tax and employment law
Federal rules that are stable and public: overtime at one and a half times the regular rate for hours over 40 in a workweek under the FLSA, I-9 and W-4 basics, employer and employee shares of FICA, and quarterly Form 941. Skip year-dependent amounts such as wage bases.
Worked example (invented). A carpenter paid $30 an hour works 46 hours in a workweek. Straight time: 40 x 30 = $1,200. Overtime: 6 x 45 = $270. Gross: $1,470. Check: 46 x 30 = 1,380, plus the half-time premium 6 x 15 = 90, gives 1,470.
Which listed books to open
These are our pairings from the book titles, not NASCLA's mapping:
- NASCLA Contractors Guide to Business, Law and Project Management: business organization, contracts, bonds, insurance, payroll, tax and financial statements.
- Construction Project Management: delivery methods, estimating, bidding and contract administration.
- Construction Jobsite Management: changes, documentation and the field side of the contract.
Tab these three first and stack them on top. The reference books guide has the editions.
How to study it
- Do the arithmetic until it is automatic. Markup and margin, retainage, ratios, depreciation and overtime need no book once you know the method, so they are the fastest points on the exam.
- Learn the vocabulary cold. Many questions turn on one term: obligee, retainage, liquidated damages, change directive. A glossary lookup costs minutes.
- Read for the reasoning in contract questions. Ask who bears the risk and what the documents say, not what you would do on your own job.
- Keep state rules out of your answers. When a question needs a specific deadline or amount, it gives you the facts or points to a listed reference.
