Explanation: A constructability review is a critical process during the design and planning stages. It involves a detailed analysis of the construction documents to identify potential obstacles, conflicts, or inefficiencies that could impede construction, increase costs, or lower quality. By addressing these issues proactively, the project team can save significant time and money. While the review may influence the budget and contractor selection, its primary goal is issue resolution.

Explanation: The Design-Build (DB) delivery method is characterized by a single point of responsibility for the owner. The owner contracts with one entity, the design-builder, who is responsible for both the design and construction of the project. This contrasts with Design-Bid-Build, where the owner has separate contracts with the designer and the contractor.

Explanation: The critical path is the longest sequence of dependent tasks in a project schedule. The duration of the critical path determines the shortest possible duration for the entire project. Any delay to a task on the critical path will delay the project completion date. Tasks not on the critical path have 'float' or 'slack' and can be delayed to some extent without affecting the project deadline.

Explanation: When a contractor submits a claim for differing site conditions, the construction manager must first consult the contract. Most construction contracts contain a 'Differing Site Conditions' or 'Unforeseen Conditions' clause that outlines the procedures for handling such claims. The CM must follow these procedures, which typically involve investigating the claim, notifying the owner, and evaluating the claim's validity based on the contract terms.

Explanation: Lagging indicators measure past performance and outcomes. The OSHA recordable incident rate is a classic example of a lagging indicator because it measures the number of incidents that have already occurred. Leading indicators, in contrast, are proactive measures that can predict future safety performance, such as safety training hours, audit results, and near-miss reporting.

Explanation: An RFI is a formal written process used by contractors to ask for clarification of the plans, specifications, or other contract documents. RFIs are essential for resolving uncertainties before they lead to costly mistakes or disputes. While an RFI response might lead to a change order, the primary purpose of the RFI itself is to seek clarification, not to request a change.

Explanation: Value engineering is a systematic method to improve the 'value' of a project by analyzing its functions. The core principle is to achieve the essential functions at the lowest life-cycle cost without sacrificing quality, reliability, performance, or safety. It's about finding the best balance between cost, function, and quality, not just cutting costs.

Explanation: A performance bond is a type of surety bond, not an insurance policy in the traditional sense, but it serves a similar purpose. It is issued by a surety company to guarantee the contractor's performance. If the contractor defaults, the surety can either complete the project or provide funds for the owner to do so. Builder's Risk covers damage to the project itself, CGL covers third-party claims, and Workers' Compensation covers employee injuries.

Explanation: 'Pay-when-paid' clauses are common in subcontracts and make the general contractor's receipt of payment from the owner a condition for paying the subcontractor. A stricter version, the 'pay-if-paid' clause, can shift the entire risk of owner non-payment to the subcontractor. The enforceability of these clauses varies by jurisdiction.

Explanation: Quality Assurance (QA) is a proactive process focused on preventing defects. It involves establishing a system of procedures, standards, and policies to ensure that quality is built into the project from the start. Quality Control (QC), on the other hand, is a reactive process focused on identifying defects through inspection and testing of the completed work. A comprehensive quality management program includes both QA and QC.
