Time-location schedules (linear schedules) have always fascinated me for their ability to convey information in a powerful, visual, straightforward way. However, the literature on time-location scheduling is insufficient and needs to be boosted." Aldo says the main takeaway he wants readers to get from his article is that "time-location scheduling is important in presenting the full schedule in one page (rather than in multiple-sheet bar charts) and its applicability in forensic analysis, allowing the analyst to identify production patterns, use the measured mile technique, and identify causes of delays." Aldo believes his article is "useful to anybody dealing with linear (rectilinear or repetitive works), either with mining, or an oil and gas, or a roadwork project."

Winter, PSP FAACE, says, "While working on the recommended practices for Critical Path Method (CPM) baseline schedule analysis and update schedule analysis, I noticed that we kept recommending that schedulers check milestone activities, but we never said how to do this. I realized this is because milestones require entirely different rules than standard activities." In commenting on the main takeaway Ron wants readers to get, he says, "Formal rules for creating and reviewing CPM milestones are required to manage milestones in CPM schedules professionally. Proper statusing a milestone should be a paramount consideration, way above that of a standard CPM activity. Many milestones represent a contractual requirement. Since logic is the sole property of a milestone, then every logical relationship to and from a milestone should be well justified. Sadly, statistical evidence from the construction industry shows that milestone logic is regularly violated in practice."

I have also personally been experiencing the issues set out in my article on several projects, from issues with major equipment to small parts that significantly impact the schedule." 1. Consider the global supply chain when building your schedule 2. Start engaging with the market early to explain the project and the timescales to create interest 3. Make your organization an organization that supplies the desire to work with. In a heated market, the supply chain can be selective, so professionalism and collaboration with the client are very important.

However, many planners don't exploit the full capacity of time-location schedules. In this article, the author shows some applications and benefits of time-location schedules in project validation and forensic analysis: (i) consolidation of information, (ⅱ) schedule validation, (ⅲ) progress monitoring, and (ⅳ) tool for forensic schedule analysis.

查看更多>>摘要：Several AACE recommended practices (RP) mention that the scheduler should specifically consider milestones in creating and reviewing the typical construction schedule. These RPs do not detail what should be considered when reviewing milestones. It is not enough for the scheduler to look at them and hope that something 'pops out.' Advanced schedulers should focus on a list of specific topics. This article discusses the hows and whys of the proper use of milestones in CPM schedules and how to make better schedules. From baseline schedules to schedule updates, this handy guide gives advanced schedulers more tools to ensure better schedules and better run projects. This article was first presented as PS-4151 at the 2023 AACE International Conference & Expo.

Impacts such as COVID-19, the war in Ukraine, economic pressures and focus on social value added additional challenges to procurement in an industry already dealing with several fundamental problems. The additional impact of a booming construction market for major and mega programs across many sectors in the US, has created an unprecedented challenge in securing supply chain. The competition for scarce resources: materials, services and work, has put an increased emphasis on procurement methodologies and brought procurement planning forward in the project lifecycle. The wide range of contract and commercial models available today, from traditional design-bid-build, through the progressive design build or CM-GC to various creative hybrid models, offer a wide range of options and opportunities for procurement to ensure project success. However, the selection of a suboptimal procurement strategy can have significant implications on project deliverability within assumed parameters, which may not be felt even for 24 months post contract award, at which time it generally cannot be changed or adjusted. To ensure creation of a sound procurement strategy, the development of procurement options that aligns with the Total Cost Management Framework offers promising results. The proposed process, in which clients can work through in a structured and methodical way, to identify the criteria, prioritize them and then systematically assess them against a range of contract and commercial options, offers a robust method of arriving at the optimal procurement strategy for the major project today.
