CMGT 410 Midterm Exam – 25 Questions on Underpinning, Tiebacks, Slurry Walls – Construction Management 2025/2026

This document features 25 midterm exam questions and verified answers for the CMGT 410 course (Construction Management) for the 2025/2026 academic year. It is specifically tailored for university-level students studying construction engineering, project management, or geotechnical systems. The questions focus on real-world construction scenarios, providing essential knowledge and reasoning for safe and effective ground engineering practices. Topics include: Retaining systems, including the use and limitations of soldier pile walls, soil nails, helical tiebacks, and micropile systems Underpinning methods, including their applications, design responsibilities, and safety concerns like vibrations, surcharge loads, and trench failures Excavation safety standards, such as required spacing for trench boxes, sloping/benching rules, and mitigating collapse risks Jet and fluid grouting techniques, particularly the use of triple fluid jet systems to improve soil-cement mix quality Slurry wall construction, including the properties of bentonite (thixotropy and filter cake effects), and the common causes of system failure (e.g., tremie malfunction) This resource also addresses structural concerns in low headroom scenarios, using micropile or helical piles, and reviews the use of structural slurry walls in geotechnical construction. The content combines factual recall with applied understanding, making it ideal for midterm prep. Recommended for: Construction Management Majors (CMGT) Civil Engineering Undergraduates Geotechnical Engineering Students Architecture or Structural Engineering Students focusing on foundations and site prep This document is a concise, clear, and high-utility study guide for mastering structural underpinning and foundation system principles in construction.
