Nivaar worked solution (AI-drafted; not reviewed by a licensed engineer)
Paper format. 98-Civ-B8 Management of Construction, National Exams December 2016. Three hours, closed book, one approved calculator (Casio or Sharp). Six questions of equal value (20 marks each); any five constitute a complete paper and only the first five presented in the answer book are marked. All six are solved here, because the set is a study resource rather than an examination script.

Both instruments are surety bonds rather than insurance, and the distinction matters before any comparison can be made. An insurance policy is a two-party contract in which the insurer accepts a risk in exchange for a premium and expects to pay claims out of the premium pool. A surety bond is a three-party instrument — principal (the contractor), obligee (the owner) and surety — in which the surety guarantees the principal’s performance and, having paid the obligee, has a right of indemnity back against the principal. The surety therefore expects no losses at all: it underwrites the contractor’s character, capacity and capital much as a lender would, and the premium is a fee for the guarantee rather than a pooled risk charge. In Canada these are issued on the CCDC 220 (bid), 221 (performance) and 222 (labour and material payment) forms.
A bid bond guarantees the tender. It is submitted with the bid, usually for 5 to 10 per cent of the bid price, and it promises that if the bidder is awarded the contract it will enter into the contract at the price bid and furnish the required performance and payment bonds. If the bidder refuses, the surety pays the owner the difference between that bid and the next acceptable one, up to the bond amount. Its life is short — it expires when the contract is signed or the tender period lapses — and its purpose is to deter frivolous or mistaken bids and to protect the owner against the cost of re-tendering or awarding to a higher bidder. Because the surety will only issue a bid bond to a contractor it is prepared to bond for performance, the bid bond also serves as a pre-qualification screen: it is the surety’s statement that this contractor is financially capable of the work.
A performance bond guarantees the contract. It is furnished after award, is conventionally 50 or 100 per cent of the contract price, and remains in force through construction and usually through the warranty period. If the contractor is declared in default and the contract terminated, the surety may complete the work itself, arrange a completion contractor, finance the original contractor through the difficulty, or pay the owner its excess completion costs up to the penal sum. The obligation is much larger, much longer and far more onerous than the bid bond’s, which is reflected in the premium: a bid bond is nominal, while a performance bond typically costs in the range of half a per cent to one and a half per cent of the contract price, on a sliding scale that falls as the contract value rises.
| Aspect | Bid bond | Performance bond |
|---|---|---|
| What is guaranteed | That the bidder will sign the contract at its bid price and provide the required bonds | That the contractor will complete the work per the contract |
| When provided | With the tender | After award, before the work starts |
| Typical amount | 5–10 % of the bid | 50–100 % of the contract price |
| Duration | Tender validity period only | Construction plus warranty period |
| Trigger | Bidder refuses to execute the contract | Owner declares the contractor in default |
| Surety’s remedy on call | Pay the difference to the next acceptable bid, capped at the bond | Complete, re-tender, finance the contractor, or pay excess costs to the penal sum |
| Relative premium | Nominal | Roughly 0.5–1.5 % of contract value |
| Canadian form | CCDC 220 | CCDC 221 |
Neither bond protects subcontractors or suppliers — that is the function of the separate labour and material payment bond (CCDC 222), which is normally required alongside the performance bond and which gives unpaid subtrades a claim against the surety. The three are commonly issued as a set and are the reason public owners can award to the low bidder with reasonable confidence.
A construction lien (builders lien in British Columbia, construction lien in Ontario, mechanics lien elsewhere) is a statutory charge on the improved land in favour of anyone who supplied work or material to the improvement. Its purpose is to solve a problem the common law of contract cannot: a subcontractor or supplier has no contract with the owner, so if the general contractor fails to pay, it has no claim against the party whose property has been enriched by its work. The lien statutes correct that by attaching the unpaid claim to the land itself, giving subtrades security they could not otherwise obtain, and by requiring a holdback that reserves a fund out of which those claims can be satisfied. The right is a creature of statute, cannot be waived by contract in most provinces, and must be exercised strictly within the statutory deadlines.
The mechanics turn on three linked elements:
Two release mechanisms matter in practice. The owner or contractor may pay the disputed amount into court, or post a lien bond, and obtain an order removing the lien from title — the security simply moves from the land to the money, which lets the project financing continue while the dispute is resolved. And a lien filed without reasonable basis exposes the claimant to damages, so the remedy is not a costless tactic. Across Canada the lien framework is now being supplemented by prompt-payment legislation and adjudication, which attack the same problem from the other end by shortening the payment cycle rather than by securing the unpaid claim.
