Construction Management — Good-to-Know Rules of Thumb

Construction Management — Good-to-Know Rules of Thumb

Construction management lives at the intersection of three hard realities: the license (state GC law — you cannot legally contract without it), the credential (CCM/DBIA — what owners require in RFPs), and the field (OSHA — what keeps people alive). This guide covers the credentials and knowledge that don't get standalone guides, the standards you'll be held to, and the judgment the exams can't test.

1. The niche and standard-practice credentials (no standalone guides — this is their home)

• CACM (Certified Associate Construction Manager) — CMCI's junior tier under the CCM. Take it early-career when you don't yet meet the CCM's 48-month CM experience bar; it's a credible "CCM-track" signal on a resume. Graduate to CCM — don't camp here.
• Associate DBIA — DBIA's junior tier: reduced experience/education requirements, same doctrinal core (Design-Build Done Right). The right move for designers and builders in their first design-build roles; the full DBIA designation follows with experience.
• CAC (Certified Associate Constructor) / CPC (Certified Professional Constructor), American Institute of Constructors — the constructor-side credentials (AIC), complementing CMAA's management-side CCM. CAC is entry-level (often taken near graduation); CPC is the experienced constructor's mark. In hiring, CCM ≈ owner's/CM side, CPC ≈ builder side — know which side of the table you're on.
• LEED Green Associate / LEED AP BD+C (GBCI/USGBC) — GA is the vocabulary credential (anyone on a green project); AP BD+C is the practitioner credential for managing LEED documentation, credits, and commissioning on building projects. Take AP BD+C when you run LEED projects — owners' sustainability requirements increasingly name it.
• OSHA 30-Hour Construction Card — not a certification, a training credential: 30 hours of construction safety training from an OSHA-authorized trainer. Many owners and GCs require it for superintendents and CM field staff; some states (NY, NV, others) effectively mandate it on certain projects. It expires in the sense that employers want it current (commonly refreshed every 3–5 years). Get it before you need it — it's the cheapest credibility on a jobsite.
• PMP (PMI) — the project-management credential many CMs pair with the CCM; see the shared guide: ../shared/pmp-study-guide.md

2. Standards mastery

AIA Contract Documents (A201 General Conditions, A101)

The industry's default contract language. Know cold: the change-order/claim notice machinery (written notice within 21 days of the event or when it should have been recognized — miss it and the claim dies), the architect's role (initial decision maker on claims, certifier of payment — not the owner's agent for means and methods), dispute resolution (mediation then binding arbitration or litigation per the agreement), and termination provisions. Compliance = administering the contract as written; the most common violation is informal practice (verbal directions, late notices) that waives contractual rights.

ConsensusDocs

The AGC/COAA/owner-group alternative to AIA — written from a more collaborative, less architect-centric stance. Know it exists and its philosophical difference (ConsensusDocs assumes best practices like lean and collaboration; AIA assumes traditional roles). On a ConsensusDocs project, don't cite AIA defaults.

CSI MasterFormat (2020) / UniFormat

MasterFormat's 50 divisions organize specifications and bidding (Division 03 concrete, 07 thermal/moisture, 26 electrical — know the major division numbers cold); UniFormat organizes by building element (foundations, superstructure, interiors) for early estimating. Exam and practice rule: UniFormat for conceptual estimates, MasterFormat for detailed bids and specs. Common violation: spec sections that don't match the drawings' division structure — a coordination failure that breeds change orders.

ISO 19650 (BIM information management)

The international BIM standard (UK-origin, BS EN ISO 19650): information requirements (OIR → PIR → EIR), the common data environment (CDE), and level of information need. On BIM-mandated projects (increasingly public work), the CM's job includes information management — know the EIR/BEP (BIM execution plan) workflow and that model liability must be contracted (LOD definitions allocate who relies on what).

PMBOK Guide

The project-management theory under the CCM's domains — see the shared PMP guide. The CM-relevant translation: integration management = the CM's coordination role; the PMBOK's risk and procurement knowledge areas map directly onto CM practice.

IBC (International Building Code) / ACI 318 / ASTM

The CM doesn't design to them but administers them: the IBC is adopted (with amendments) by the AHJ — know the permit/inspection sequence it drives (footing, foundation, framing, insulation, final); ACI 318 governs structural concrete (the CM verifies testing/inspection per Chapter 26/27 — special inspections); ASTM standards are invoked by reference in specs (the CM's submittal and testing program enforces them). Common violation: proceeding past a required inspection without sign-off — the AHJ can order uncovering.

3. Regulations mastery

OSHA 29 CFR 1926 subpart map (the exam-tested numbers)

Memorization strategy: learn the trigger numbers (6' fall, 5' excavation, 4:1 scaffold, 25' egress, 20' power line, 3' ladder extension, 2' spoil setback) — the exams test thresholds, not prose.

Multi-employer citation policy (OSHA CPL 2-0.124)

On construction sites OSHA can cite more than the employer whose worker was exposed. Know the four roles: creating employer (caused the hazard), exposing employer (its workers were exposed), correcting employer (responsible for fixing it — typically the GC/CM), controlling employer (has general supervisory authority — the GC/CM again). The exam's scenario: a subcontractor's unprotected trench injures the sub's worker — OSHA can cite the sub (creating/exposing) and the GC (controlling/correcting if it knew or should have known). CMs advising owners need this cold.

Davis-Bacon Act (prevailing wage)

Federal construction over $2,000: pay locally prevailing wages/fringes per DOL wage determinations; certified payrolls weekly; the CM/prime verifies subcontractor compliance. State "little Davis-Bacon" acts extend this to state-funded work with their own thresholds and determinations. Common violations: misclassifying laborers as operators (or as independent contractors), and fringe-benefit shortfalls.

EPA Construction General Permit (stormwater)

NPDES permit for land disturbance ≥1 acre: the SWPPP (stormwater pollution prevention plan), erosion/sediment controls, inspections (typically weekly + after rain events), and Notice of Intent/Termination filings. The CM ensures the SWPPP is implemented — violations are per-day penalties that accumulate fast.

Mechanics lien laws / payment bonds

State lien statutes (see the CA/FL guides for deadline mechanics) plus Miller Act bonds on federal work (performance + payment bonds required at the federal threshold — verify current) and state Little Miller Acts. The CM's role: manage lien releases with each pay app (conditional releases with billing, unconditional only on confirmed payment), and verify bond coverage on bonded projects.

Building permits and the AHJ

No work without the permit; the AHJ (city/county building department, fire marshal for life-safety) interprets the code locally. Veteran rule: the inspector's interpretation is the code on that job — argue in the office with code sections, never in the field with attitude.

4. Delivery methods and contract forms (exam cross-cutting knowledge)

Every construction credential's exam touches these — one consolidated reference:

• Design-Bid-Build (DBB): owner holds separate design and construction contracts; linear; slowest; prescriptive documents; owner warrants the plans (Spearin). Best when scope is fully definable.
• Design-Build (DB): one contract for design + construction; fastest (fast-tracking); owner gives up design control, gains single-point responsibility. See the DBIA guide.
• CM-at-Risk (CMAR): CM holds the trade contracts and guarantees a GMP; designer still separate. Owner keeps design control + gets early contractor input and price certainty.
• CM-as-Agent (CMa): pure advisory; owner holds trade contracts. Maximum owner control, maximum owner risk.
• Multi-prime: owner holds many prime contracts directly. Coordination risk sits entirely on the owner — the exam's "who bears coordination risk" answer.
• IPD (Integrated Project Delivery): multi-party agreement with shared risk/reward pool; lean/BIM-native; rare, tested conceptually.

Contract payment forms: Lump Sum (contractor owns cost risk — needs complete documents), Unit Price (owner owns quantity risk — good for civil/earthwork), Cost-Plus-Fee (owner owns cost risk — fastest start, needs trust + audit rights), GMP (cost-plus with a ceiling; savings/overrun sharing per contract — the CMAR default). The exam gives the owner's priority (certainty vs. speed vs. flexibility) and expects the matching form.

5. Rules of thumb

• Scheduling: total float belongs to the project (unless contracted otherwise); 10% of activities typically drive the critical path — manage those daily, the rest weekly.
• EVM: CPI < 0.9 or SPI < 0.9 sustained two periods = recovery plan territory. TCPI > 1.1 to hit BAC = unlikely without scope change.
• Estimating: conceptual ±15–25%, detailed ±3–5%. Contingency: 5–10% construction on well-defined work, 15–20%+ on renovation (unknown conditions).
• Concrete: order ~5–10% over theoretical; 1 CY ≈ 81 sq ft at 4" thick. Cure 7 days minimum (longer in cold).
• Earthwork: soil swells ~20–30% when excavated (swell factor) and compacts to ~90% of bank volume — the takeoff trap that bankrupts beginners.
• Fall protection: 6' in construction (1926), 4' in general industry (1910) — know which standard governs your site.
• Crane: never work under the load; power-line clearance 20' for lines up to 350 kV (verify per 1926 Subpart CC for the voltage).
• Lien math: prelim notice → record → foreclose; every deadline is fatal; when in doubt, serve early.
• Cash flow: underbilling (costs ahead of billings) kills contractors faster than unprofitability — watch the over/underbilling report monthly.
• Unit reflexes: 1 CY = 27 CF; board foot = 144 cu in; roofing square = 100 sq ft; a 2×4 is 1.5" × 3.5" (the exam tests nominal vs. actual).

6. Veteran knowledge

• Exams don't test: how to run an OAC meeting with a hostile architect, how to tell an owner his budget is fiction without losing the job, or how to read a superintendent's silence. The CCM gets you shortlisted; judgment gets you hired.
• Costly beginner mistakes: (1) Trusting the schedule update the GC hands you — always check logic ties and constraints before believing float. (2) Approving pay apps against % complete claimed rather than work in place — that's how overpayment happens. (3) Letting submittals lag — every late submittal is a future delay claim wearing a disguise. (4) Verbal direction — if it isn't written, it didn't happen, and you'll pay for it.
• When to call a specialist: construction defects litigation (construction attorney — before you write anything about the defect), structural questions in the field (the EOR — never freelance structural judgment), environmental contamination discovered during excavation (environmental consultant + attorney — stop work first), and tax/nexus issues on multi-state work (CPA).
• The document is the project. In claims, the party with the daily reports, dated photos, and written notices wins. Superintendents who "don't do paperwork" are manufacturing someone else's claim.
• Buyout discipline. The estimate is a hypothesis; buyout (negotiating final subcontractor pricing after award) is where margin is made or lost. Track buyout savings/slippage against the estimate weekly — a project that "looks fine" at 60% bought out can be underwater by 90%.
• RFI hygiene. Requests for information are the project's early-warning system: an RFI log with aging unanswered items is a delay claim in gestation. The CM's job is aging the log, not just filing it.
• Subcontractor default risk. A sub 15% below the next bidder isn't a bargain — it's a default waiting to happen. Prequalify (financials, backlog, key personnel), and on critical trades consider subcontractor default insurance or dual-sourcing.

7. Change orders, claims, and disputes (the exam's favorite storyline)

Every construction exam — CCM, DBIA, and every state law exam — runs variations on one storyline: something changed, someone didn't write it down, and now there's a fight about money or time. The doctrine:

• Change order vs. construction change directive vs. field order. A change order is bilateral (agreed scope + price + time). A construction change directive (AIA) orders the work before price is agreed — the contractor proceeds and the price is determined later by agreed method. A field order / minor change is architect-authorized and supposedly cost-neutral — the trap is that "minor" changes accumulate into real money without paperwork.
• Notice requirements are conditions precedent. A201 requires written notice of claims within 21 days of the event (or when the claimant should have recognized it). Miss the notice and the claim dies regardless of merit — exams test this as a pure procedural kill.
• Delay taxonomy: excusable + compensable (owner-caused — contractor gets time and money), excusable + non-compensable (force majeure — time only), non-excusable (contractor-caused — neither; liquidated damages apply). Concurrent delay (both sides delaying simultaneously) generally yields time but no money — the exam's "who pays" answer for concurrent delay is nobody.
• Liquidated damages vs. penalty. LDs are a genuine pre-estimate of the owner's daily loss, enforceable; a penalty is punishment, unenforceable. The exam tests whether a per-day figure looks like a real estimate (tied to financing, lost revenue) or a round-number threat.
• Dispute ladder: negotiation → mediation (non-binding, usually contractually required first) → binding arbitration or litigation (per the contract's election). Know that mediation is not binding and arbitration generally is, with very limited appeal rights.
