Chapter 29 — Further Reading

Nine pointers. Every one is a real body, standard, or resource; none of the section numbers, edition numbers, or URLs you might expect are invented here, because inventing them is worse than omitting them. Where I am describing a document rather than citing it precisely, I say so.

1. AACE International — the recommended practice on forensic schedule analysis. AACE International (the Association for the Advancement of Cost Engineering) publishes a lengthy recommended practice that catalogues and classifies the methods of schedule delay analysis: prospective and retrospective, observational and modeled, additive and subtractive. It describes what data each method requires, what it can and cannot prove, and the conditions under which each is appropriate. This is the reference North American practitioners and testifying experts most commonly work from, and both sides of a dispute frequently cite it.

Read it when: you are about to prepare or receive a delay analysis, or you want to understand why a consultant is calling your work "impacted as-planned" and saying it dismissively. Do not expect it to be binding — it is guidance, not law, unless your contract adopts it.

2. The Society of Construction Law — Delay and Disruption Protocol. The international counterpart. It sets out guidance on delay analysis methodology, concurrency, float ownership, time extensions, prolongation and disruption costs, and the treatment of acceleration. It is widely referenced in the United Kingdom, the Middle East, Asia, and Australia, and increasingly cited in North American practice.

Read it when: you work internationally, or when you want a second, independently developed framework to test your instincts against. Reading it alongside the AACE practice is genuinely educational — they agree on more than you expect and differ in ways that reveal how much of this subject is convention rather than physics. Neither is law, and both say plainly that treatment varies by jurisdiction.

3. Your own contract's scheduling specification — and it is not on this list as a joke. The single most valuable document you can read this week is the scheduling section of the contract you are working under. It will tell you the required update frequency and data date, the maximum activity duration, whether constraints are permitted, what the narrative must contain, whether an update is a condition of payment, what form a time-extension request must take, and — if you are lucky — who owns float. Public agencies publish their standard specifications, so you can read a dozen for free without signing anything: state departments of transportation, large school districts, university systems, and federal construction agencies all post theirs.

Read it when: at buyout. Not in month nine.

4. AIA contract documents — A201 General Conditions, and the CM-at-Risk family (A133 with its associated general conditions). The A201 general conditions contain the provisions this chapter keeps pointing at: time, delays and extensions of time, notice, claims procedure, and the initial-decision process. The CM-at-Risk family governs the Northgate arrangement — guaranteed maximum price, cost of the work, contingency, savings split, and audit rights. Read the documents themselves rather than a summary of them, including the summary in this book. ConsensusDocs and EJCDC publish parallel families that allocate several of these risks differently, and comparing two forms clause by clause on the same subject is one of the fastest ways to learn what is negotiable.

Read it when: before you sign anything, and again the first time somebody uses the word "notice" at you.

5. The Construction Management Association of America (CMAA) and the Project Management Institute (PMI) — standards of practice on time management. CMAA publishes standards of practice for construction management covering time management, cost management, and program management. PMI's body of knowledge covers schedule management from a general project-management perspective, and PMI also maintains a practice standard specifically on scheduling. Both are useful and both need translating. PMI's material was not written for a job site with twenty subcontractors and a mill slot in it; take the discipline and adapt the vocabulary.

Read it when: you are studying for a certification, or you need a defensible vocabulary for a process you already understand intuitively.

6. Any serious construction scheduling textbook that works CPM by hand. There are several long-established academic texts on construction planning and scheduling used in university CM programs. Pick one and work its problems with a pencil — forward pass, backward pass, float, resource leveling, crashing. What you want from it is not theory; it is repetitions. The reason this chapter can tell you a critical path moved is that somebody, once, made you compute a backward pass by hand thirty times.

Read it when: you cannot yet look at a nine-activity network and predict which branch will govern. Pair it with Appendix B.

7. Business Roundtable and trade-association studies on the effects of scheduled overtime. The productivity-loss curves practitioners use for sustained overtime trace back to a body of work that includes the Business Roundtable's construction industry cost-effectiveness studies and to schedule-related productivity factors published by mechanical and electrical contractor associations. Use them the way this chapter does: as a starting point, hedged. The magnitudes are widely reported and directionally reliable; the precise percentage for your trade, season, crew, and task is not in any book. If you are going to argue an inefficiency number in a negotiation, you want a published factor and your own measured data, and the measured data is what wins.

Read it when: you are pricing an acceleration, or defending one.

8. OSHA 29 CFR 1926 — Construction, and NIOSH research on fatigue and shift work. The OSHA construction standards are the floor for the physical controls this chapter's acceleration touches: scaffolding, fall protection, and the competent-person requirements that failed in week 34. NIOSH — the National Institute for Occupational Safety and Health — publishes research and guidance on worker fatigue, long work hours, and shift work, which is the mechanism connecting a schedule decision to an incident.

Read it when: you are writing the safety impact review in §29.9. Read the fatigue material especially, because it is the part of the acceleration decision that has no line on any cost sheet and the part your crews will actually feel.

9. ENR (Engineering News-Record), and your own company's closeout files. ENR covers real projects going late, real disputes, and real recoveries, and reading it habitually builds a pattern library faster than any textbook. But the better resource is closer: ask your company for the schedule updates and lessons-learned files from a job that finished late. Read the updates in sequence and find the month the float went. It is always visible in retrospect and it was always visible at the time. Doing that once, on a real job your company actually built, will teach you more about this chapter than anything else on this list.

Read it when: now, and then again after your first project of your own goes sideways.

A closing note on how to read all of this. Every source above describes practice that varies by jurisdiction, by contract form, and over time. Notice periods, the enforceability of float-ownership and no-damage-for-delay clauses, the treatment of concurrent delay, and the doctrine of constructive acceleration are all genuinely different in different places, and they change. None of this — and nothing in this chapter — is legal advice. Use it to recognize the issue, to preserve your position contemporaneously, and to arrive at your attorney's office with a real question and a real record instead of a story.
