Substructure Assemblies Estimate with RSMeans + Bluebeam | Footings, Slab, and Excavation

Disclaimer: For educational use only—always verify with project drawings, local codes, and professional judgment. This lab continues CMP 315: Construction Quantity Surveying at Michigan State University and focuses on developing a substructure assemblies estimate using RSMeans cost data and Bluebeam quantity takeoff workflows. In this lab, we cover: • What an assemblies estimate is—and why it is used in early budgeting • Why estimating begins with the substructure • How to calibrate scale and activate Snap settings in Bluebeam • Strip footing quantity takeoff (LF, width, depth) • Pad/spread footing measurement and classification • Foundation wall takeoff and proportional cost adjustments • Slab-on-grade area and thickness measurement • Mass excavation boundary construction and depth calculation • Foundation underdrain linear measurement • Foundation dampproofing quantity extraction and legend creation • Matching measured quantities to RSMeans assemblies • Applying General Contractor overhead & profit • Why assemblies estimates are not for bidding (±20% accuracy range) This lecture emphasizes proper drawing setup, dimensional logic dictated by cost references, and disciplined quantity extraction before pricing. Assemblies estimating is presented as a structured budgeting method for feasibility analysis and scope alignment—not as a final bid or contract price. 📘 Course: CMP 315 – Construction Quantity Surveying 🎓 Instructor: Armin Yeganeh, Ph.D. 🏫 Program: Construction Management, Michigan State University
