Safety 3. resource 4. preferential PDM formation - Answers - collaboration of people - each node has a # w/ activity scheduling phase - Answers HOW LONG first determining durations tool - Answers - the cost estimate (because its usually deriven from durations and created for you before you schedule) - things to think about when scheduling - Answers - evaluate each task individually - consult experienced pros - assume standard crew size etc. - adjust timing for job conditions - 8 hour workday how long is a workday in basic scheduling - Answers 8 hours overall schedule length - Answers how long will project take (according to schedule) activities that must stay on track / in order - Answers critical path float - Answers scheduling leeway total float - Answers total amount of delay of an activity before WHOLE project is delayed free float - Answers amount of delay of an activity before succeeding activity is delayed ES - Answers early start - earliest possible time to start EF - Answers early finish - earliest possible time to finish LS - Answers late start - latest possible time to start before project's completion is delayed LF - Answers late finish - latest possible time to finish before the project's completion is delayed forward pass - Answers uses table to total up ordered days - can use to calculate ES and EF backward pass - Answers uses table to total up ordered days - can use to calculate LS and LF forward pass formula - Answers early start + duration = early finish backward pass formula - Answers late finish - duration = late start who should know about schedule changes right away - Answers SUBS, senior managment, owner, vendors, designers, (Everyone) most popular scheduling programs - Answers - primavera - asta 3 calcs - Answers forward pass, backward pass, total float what activities are on the CRITICAL path - Answers ones with no float Project Control - Answers keeping score --- monitoring+reporting field info who anticipates in project control - Answers PM & Super components/tools to monitor in project control cycle - Answers plans&specs(quality), estimate(cost), schedule(time) 7 steps to control cycle - Answers 1. develop project plan 2. establish benchmarks 3. monitor performance 4. assess deviations 5. evaluate corrective options 6. adjust 7. document, report, evaluate results how to track progress (tools) - Answers field reports, time cards, sub billings, delivery tickets, material invoices, equipment time tickets, job logs 2. field data collection purposes - Answers - gives a sense for deviation from what was planned to see if you are on track with project cost & sched. - adds to database so you can estimate better next time factors impacting project performance - Answers -weather conditions - quality of workforce -quality of supervision - sequencing accuracy - change orders - overcrowded jobsite - defective materials - inadequate tools & equipment quality tracking tools (more than plans & specs) - Answers field data/reports, submittals, shop drawings, mock ups, inspections, tests cost control - Answers the tracking of performed cost vs. planned cost (in terms of cost & time) cost code - Answers number corresponding with activity (part of CSI div. ) for reference of cost, time, & info variance - Answers - difference between planned and actual performance; important to look at discrepencies for next time + project evaluations T or F - overruns on material budget and sub prices are the biggest contributers to losses on projects - Answers False - typically this is not the main contributer material price fluctuations effect - Answers - typically non-event (esp since its smaller in terms of overall project cost) - usually GC will eat the charge - if its CRAZY drastic, GC can try to negotiate with owner escalation clause - Answers agreement in contract that a material has high flux - pre-emptively assumes increase/dec Subcontractor price increase effect - Answers - subs are contract bound with quoted price -usually sub will eat overrun - if sub contract hasn't been executed yet they can renegotiate price /rebid quantity takeoff error effect - Answers - GC will try to negotiate best price and (again) eat cost worst case schedule control - Answers managing durations of activities crashing the schedule - Answers happens when you think you'll go overtime - compressing certain
