COMBAT CONSTRUCTION EXAM 2026
ENGINEERING OPERATIONS MODULE SOLVED
ITEMS AND RESPONSE KEY
◉ Available Design Methods for Construction Loads. Answer:
Allowable Stress Design (ASD)
Load and Resistance Factor Design (LRFD)
◉ Building Type & Construction Method. Answer: Residential: Light
wood stick framing
Commercial: Wood, steel, or masonry
High-rise and other commercial: heavy steel framing or reinforced
concrete
Long-Span Bridges: steel cables
◉ Wood Framing. Answer: Most common way to build houses in NA
◉ Simplified Building Procedure for Wood House. Answer: 1. Place
concrete foundation
2. Place first floor walls
3. Construct wood platform to build second floor
4. Place second floor walls
,5. Place roof on top of 2nd floor walls
◉ Steel Framing. Answer: Most common for high-rise and
commercial buildings
Similar to wood but with less flexibility
High strength & relatively light weight
Expensive compared to other materials
◉ Concrete Structures. Answer: Concrete systems are commonly
used in high-ride buildings
More resistant to fire than steel or wood
Less prone to corrosion than steel (common for UG structures)
◉ Simplified Building Procedure for Concrete Structures. Answer: 1.
Prepare concrete mix design
2. Prepare formwork
3. Pour steel reinforcement
4. Pour Concrete
5. Allow for concrete curing process
6. Disassemble formwork
◉ Advantage of Precast Concrete. Answer: Higher quality fabrication
from casting off-site
,Can accelerate construction schedules
◉ A two-story multi-family residential structure is being
construction in a high seismic area. Which construction type is most
likely to be used?. Answer: Wood Framing
(2-story, low rise residential)
"High-seismic" is a distractor
◉ Temporary Structures. Answer: May be removed at end of
construction (usually)
May be incorporated into the finished structure
Concrete formwork is a common example of temporary structure
◉ Design Considerations of Concrete formwork. Answer: Dead Load:
weight of fresh concrete plus form self weight
Live Load: 50-75 psf depending on equipment used (to pour
concrete)
Lateral pressure exerted by fresh concrete
◉ Typical formwork material. Answer: 3/4" plywood that is coated
on one side
◉ Types of concrete formwork. Answer: Slab Formwork
, Beam Formwork
Column/Wall Formwork (look at photos)
◉ Equation for Lateral Pressures of Concrete. Answer: ACI 347R-14
Table 4.2.2.1a(a)
◉ Project Management Process Groups. Answer: Initiation ->
Planning -> executing -> Controlling and monitoring (loop back to
planning) -> closing
Ex. of loop (Value Engineering)
◉ Gantt Chart. Answer: Small to mid-size projects
Forecast & manage resources (labor, equipment, budgets, etc)
Disadvantage: doesn't show all the links/sequencing
◉ Critical Path Method (CPM). Answer: Project modeling technique
that identifies the most critical activities on a schedule
Helps monitor the assets, expenses, and advancement of the project
Activity on Node (AON) is most common
◉ PERT. Answer: Program Evaluation Review Technique (also
known as CPM)
