Utilizing another case study project, prepare a work package for direct labor for a system of work such as concrete foundations, cast-in-place concrete walls, tilt-up concrete walls, or slab-on-grade. Attach the original portion of the estimate that refers to this work package. Assume the following percentages complete and spent:

Portion of work complete Portion of estimate spent Excavation: 100% 80% Form work: 90% 100% Reinforcement steel or mesh: 85% 110% Concrete placement: 50% 40% Slab finish (if appropriate): 40% 75% Tilt-up panel erection (if appropriate): 10% 7%
