According to the given information, develop: a) A balanced bid. b) An unbalanced bid to maximize early income, assuming that ABC changes item prices within +/- 19% only. c) An unbalanced bid to maximize profit, assuming that ABC changes item prices within +/- 21% only. Also assume that you know that the actual quantities of concrete for abutment and reinforcement for abutment are 577 Sq. Ft. and 92,588 Lb., respectively. Hints: The general sequence of construction is: excavation, pile construction, footing construction, abutment construction, backfilling, girder setting, slab construction, guardrail construction, and painting.
