Who is responsible for providing and identifying the lengths of splices in reinforcement?

• A. The Engineer
• B. The Contractor
• C. The Inspector
• D. The Owner

Answer: (A)

Splice lengths are a design detail defined by the structural engineer. The engineer analyzes factors like bar size, concrete strength, and load requirements to determine how long a lap splice or mechanical splice must be and then marks those lengths on the drawings or shop drawings. The contractor then fabricates and places the reinforcement to match those specified lengths, while the inspector checks that the installed splices conform to the engineer’s design and applicable codes. The owner provides the project scope and funds the work, but does not dictate the splice lengths beyond the engineer’s design.
