Coordinate the work

Coordination is the unglamorous middle of a building project: knowing, two weeks ahead, which trade is coming, what they need to find when they arrive, which decision is due before they can start, and what inspection has to pass before the next trade can follow. This module gives you the five habits that do that work, the look-ahead schedule, one written channel, a meeting rhythm, a decision and change discipline, and a daily log, and shows what a coordinator actually does when a delivery slips and an inspection cannot happen.

1. What coordination is, and who does it on your project Understand

Module 5 gave you the sequence: what follows what, and where the inspections hold everything. Module 8 gave you the selections: what has to be chosen and delivered before each step. Coordination is the daily and weekly work of making those two things true on the ground, with real people who have other jobs, in weather, with a building department that inspects on its own calendar. It consists of managing five things: people (who is coming, and have they confirmed), information (does everyone have the current drawing, the answer to last week's question, the inspection result), decisions (what is due, from whom, by when), materials (is it on site, undamaged, in the right place) and timing (what moves if this slips).

Who does this work depends on the role you chose in Module 1, and the difference is large.

2. The look-ahead schedule

The master schedule from Module 5 says the project takes twenty weeks. Nobody can act on twenty weeks. A look-ahead schedule is the next two or three weeks of that schedule, pulled out and made specific: day by day, trade by trade, with everything each line needs written next to it. Scheduling guides suggest two-week windows for small residential jobs and three weeks for jobs with long lead times or many subcontractors. It is rewritten every week, because every week something has moved.

The discipline that makes it useful: every line is either confirmed or it is not, and the look-ahead says which. Builders' guides on the subject put it the same way: each task should have a named crew, confirmed material, and its prerequisites done or on track, and tasks too far out to verify should not be on it. One public-works specification structures its three-week look-ahead as the planned work for three weeks, the status of work underway, and the "controlling item of work" (the one thing that, if it slips, moves everything). That last idea transfers well to a house: every week, know which line is controlling.

What each line needs

A look-ahead with every cell filled and honest is a short document that takes an hour a week to maintain. On a project with a general contractor, ask for theirs and read it with these columns in mind; a contractor who cannot produce one is coordinating in their head, which works until it does not.

Where the look-ahead meets the selection log

Module 8's decide-by dates become the "decisions due" column here, and Module 8's needed-on-site dates become "materials on site." If the two documents disagree, the look-ahead is usually the more current, and the selection log gets updated; if it is not obvious which is right, that is a question for the meeting. Keep both in the dependency map and look-ahead schedule and the selection log, and read them together every week.

3. One channel, written confirmations, and the site meeting

One channel for decisions

Projects run on text messages, and text messages are where decisions go to be forgotten. The practice experienced coordinators converge on is simple: one channel for daily chatter (texts, calls, a group thread) and one for decisions (email, or a shared document, or the contractor's project app), and the rule that any decision made in the first channel gets restated in the second within the day. "As we discussed on the phone, the ceiling fan box goes at the center of the room; please confirm." The confirmation is the point. A decision one person remembers is not a decision.

Written confirmations from trades

A trade saying "yeah, we'll be there Tuesday" on the phone in week 3 is not a confirmation for Tuesday of week 6. The habit is a short written message the week before and a reminder the day before: the date, the start time, what will be ready for them, what they are bringing, and any site rule. A trade who does not reply to the week-before message is a line on the look-ahead marked "not confirmed," and that is the line you chase on Wednesday, not the one you discover empty on Tuesday.

The rhythm

Daily, during active phases: a short check at the start or end of the day with whoever is on site, and the daily log (section 7). Weekly: the site meeting, and the look-ahead reissued afterward. Trade-press writers who cover schedule discipline describe the weekly meeting with the schedule, budget changes, open decisions and open RFIs as standing items; that is the agenda below with small additions.

The site meeting

Who attends: whoever coordinates (you or the superintendent), the owner, the trades starting in the next two weeks if they will come (many will not, and a call the day before serves), and the designer when there are design questions. Notes go out within a day, to everyone who was there and everyone affected, and they say who does what by when. Ask for a reply where you need one; silence is not agreement, and you should not treat it as such on anything that costs money.

If your contractor holds a weekly meeting, go to it, bring your decisions, and ask for the notes. If they do not hold one, ask for a fifteen-minute call each week with the look-ahead in front of both of you. That request is reasonable and many good contractors will welcome it, because it means fewer calls at 7 am.

4. Access and the occupied home

A project in a house you are living in is a different project, and the proposals that did not price containment, dust control and working hours (Module 7) were not pricing your project. The practices that experienced remodelers describe are specific.

• Containment. The work zone is sealed from the living zone with plastic sheeting on a frame (a "zip wall" with a zippered door) or by weather-stripping the interior doors that separate the two. Tack mats at the zipper door catch dust from boots. Paths from the work zone to the door are protected with floor coverings.
• Dust control. Powered HEPA air scrubbers (a HEPA filter removes very fine particles; the units cost roughly $500 to $1,500 to buy and are rentable) running in the work zone, ideally arranged so that air leaks into the work zone rather than out of it ("negative air"). The house's heating and cooling fan off as much as the household can tolerate, supply and return openings inside the work zone blocked, and mid-grade pleated filters on the returns that remain open. Wet methods and HEPA-attached tools for sanding and cutting.
• Working hours. Agreed in writing before the start: start and finish times, noisy work windows, no-work days. Your jurisdiction or your HOA may set limits; those are verification items. Your household sets the rest, and the contractor prices it.
• Bathroom and utilities. Which bathroom the crew uses, or a rented portable toilet; where they wash tools (not the kitchen sink you are keeping); when water and power will be off and for how long, with notice.
• Children, pets and vulnerable people. Nobody but the trades in the work zone, ever; a plan for where children and animals are during demolition and during the days when doors are open; a specific conversation about lead and asbestos (below) if the house is old enough.
• Neighbors. Tell them before you start: what, how long, the hours, the dumpster, where trucks will park. Give them a way to reach you, not the crew. Shared walls and shared drives can make this a matter for your contract, your HOA or condominium rules, or an adviser, as much as a courtesy.

Older houses: lead and asbestos

If the house was built before 1978, lead paint is a real possibility. The Environmental Protection Agency's Renovation, Repair and Painting (RRP) rule requires lead-safe certified firms for renovation work that disturbs paint in pre-1978 housing and child-occupied facilities. The EPA's own page states that the rule generally does not apply to homeowners doing their own work in their own home, but does apply where any part of the home is rented, a child-care business operates in it, or the house is being renovated for sale; the same page recommends hiring certified firms and, for do-it-yourself work, lists steps: test or assume lead is present, contain the area, protect yourself, minimize dust with wet methods and HEPA-attached tools, clean up daily, control waste, and finish with a HEPA vacuum and wet wipe. Read it directly: EPA, RRP program for do-it-yourselfers (explains who the rule covers and the lead-safe steps for homeowners). Whether a trade you hire must be certified is a question for that trade and the EPA's lookup, and whether your state adds requirements is a verification item.

Asbestos is a separate question with its own rules; which surveys and abatement practices apply to a home renovation vary by state and locality. Asbestos was used in many building materials over many decades, and the course cannot give you a cutoff year. If you are disturbing flooring, pipe insulation, textured ceilings, siding or old drywall compound in a house of any real age, ask your building department and your state environmental agency what is required before demolition, and get testing done by a qualified firm where the answer is "test."

5. Decisions, changes, RFIs, and who decides when plans conflict

The decision log

Every decision with a cost or a schedule effect is one line in the decision log: date, what was decided, who decided, why, what it cost or saved, and which schedule line it unblocks. The log is where "we agreed the fan goes in the center" lives after the text thread has scrolled away. It is also what you read when a trade says "nobody told me." Keep it in the decision and issue logs.

No change without a written change order

A change order is the written amendment to the contract that adds, removes or alters work, states what it costs or credits, and states what it does to the schedule, signed by both sides before the work is done. Module 7 told you to look for the change-order terms in the proposal; this module is where you use them. The rule is short: no change without one. A change agreed on the phone and done the same afternoon is a dispute waiting for the invoice.

What a change order records:

• A number, and the date.
• What changes, in enough words that someone who was not there can tell what was added or removed, with a drawing or a photo attached where it helps.
• Why, and who asked for it: owner's request, a concealed condition, a design clarification, a product that became unavailable.
• The price, and how it was built: lump sum, or time and materials with the rate and the markup from the contract, and whether it is an addition or a credit.
• The schedule effect, in days, and what it does to the completion date.
• Signatures from both sides, and the date work may start.

The honest exception is genuinely urgent work: a pipe found leaking during demolition, a rotten beam that cannot wait for a signature. Even then, the practice is a written notice before the work (a photo and a two-line email: "found this; proceeding to make safe on T&M per section 9; change order to follow") and the change order within days. As an owner-builder you are both signatures, and you still write it, because the subcontractor's invoice will arrive either way and the budget tracker needs to know why.

RFIs in plain words

A request for information (RFI) is a written question, from the builder or the coordinator to the designer or engineer, when the drawings are unclear, conflict with each other or with the site, or are silent on something the work needs. It is numbered and dated, it says what the question is, what the questioner proposes if they have a view, when the answer is needed, and what happens to the schedule if it is late. Guides on the subject suggest asking roughly ten days before the answer is needed; a question asked the morning the framer needs it is not an RFI, it is a delay. The answer goes in the same log, and if it changes the work or the price, it becomes a change order.

On a small project with no architect, the RFI goes to whoever holds the design: the designer, the engineer for structural questions, or, if the drawings are the owner's own, to the building department for anything the permit depends on. The format still matters, because the written question and the written answer are what you will have when the wall is closed.

When the drawings, the field and the trade disagree

This happens on every project. The plan shows the beam at one height; the existing ceiling is lower. The drawing puts the panel on a wall where the duct now runs. The framer says "we always do it this way" about a detail the engineer drew differently. The question is never who is right. It is who decides, and the answer depends on the kind of question.

Two things the course asks you to hold onto. First, the trade's opinion is usually well informed and often correct, and you still send the design question to the designer, because the designer is the one carrying responsibility for the design and because "the plumber said it was fine" is not a record. Second, the course is never the decider. Nothing in these modules tells you whether a beam can move or a drain can offset; it tells you whom to ask and how to write the question down.

6. The homeowner-as-employer question, and site safety basics

If you hire a general contractor, their workers are ordinarily their employees or subcontractors, and the obligations of an employer are ordinarily theirs. If you coordinate trades yourself, each trade contractor is ordinarily still an independent business with its own employees. But if you hire individuals directly, pay them by the hour, supply the tools, and tell them what to do each day, you may have become an employer, with obligations that depend on where you live. The course cannot tell you whether you have; it can tell you that the question exists, what the sources it found say, and whom to ask.

At the federal level, the Occupational Safety and Health Administration (OSHA) answered a version of this question in a 2004 interpretation letter. As the research for this course reports the letter, OSHA's standards apply to "employers," meaning a person engaged in a business affecting commerce who has employees; the letter states that a typical homeowner who hires independent contractors to build or expand a house does not meet that definition and does not become a "controlling employer" over the contractors' workers, and that the homeowner's own construction expertise does not change that. The course's reading of that, which is a reading and not the letter's words, is that the analysis may change if the owner directly employs workers or supervises and controls the contractors' workers; where that line falls in any real case is for an adviser. Read it yourself: OSHA standard interpretation, December 29, 2004 (OSHA's answer on whether a homeowner hiring contractors is an employer under the OSH Act).

State law can be different, and the owner-builder statutes and handouts the research found say so in their own words:

• Florida's owner-builder exemption statute, for example, states that any unlicensed person working on an owner-builder project must be employed by the owner, who must withhold federal income tax, pay social security contributions and provide workers' compensation, and that the owner may be liable for injuries to such workers, which homeowner's insurance may not cover. Source: Florida Statutes 489.103 (the exemptions section, including the owner-builder disclosure text). That is Florida's rule for Florida; your state's exemption text, if there is one, is a verification item.
• California's licensing board, as summarized in one city's owner-builder handout, warns that an owner who pays an unlicensed individual above a stated threshold may be treated as an employer, responsible for payroll registration, withholding, disability and unemployment contributions and workers' compensation. The board's own owner-builder pages describe the broader risks: CSLB, the downside of being an owner-builder (California's licensing board on liability, liens and injured workers). Again, California's statement for California.
• Workers' compensation is commonly a separate matter from homeowner's insurance, and the thresholds at which a household becomes a covered employer vary by state, by hours and by number of workers; a payroll-services page was the research's source for that, so treat it as a prompt for the agent and the agency, not as a rule.

Whom to ask: your state's labor or workers' compensation agency, your insurance agent (in writing, about what your homeowner's policy does and does not cover on a construction site, and whether you need builder's risk and liability coverage), and an attorney or accountant if you intend to pay anyone directly. Put the questions in the verification list before the first hire, not after the first injury.

Site safety: the practical minimum for anyone coordinating a site

None of the following makes you a safety professional, and none of it replaces the trades' own obligations. It is the minimum experienced coordinators describe keeping regardless of role. Whether any of it bears on the employer question above is part of that question, for the same advisers; the course does not know.

• Verify each contractor's workers' compensation and liability coverage on a certificate of insurance before they start (Module 7), and note the expiry dates in the team directory.
• Give every crew a short site orientation on day one: access, parking, where the panel and the water and gas shutoffs are, where the first-aid kit is, the hours, what is off limits, and that children and pets are never in the work zone.
• Expect the trades to follow their own fall-protection, ladder and scaffold practices, and say so in the written site rules; if you see something that frightens you, raise it with the contractor or the trade's owner rather than instructing the worker on the ladder, and if it looks like an emergency, treat it as one.
• Keep emergency numbers and the address posted where the crew can see them; keep a first-aid kit; keep the site tidy enough that nobody trips over your materials.
• Do not direct how a trade performs its work. This is the "means and methods" line again, and it matters for safety as much as for liability.

7. The daily log

Five minutes at the end of each working day. The log records the weather; who was on site and roughly when; deliveries and their condition; inspections requested, held and their results; visitors; decisions made that day; problems found; photos taken. Coordinators who keep one describe it as among the most valuable documents they have when a delay or a dispute surfaces months later, because it is the only contemporaneous record of what actually happened on a given Tuesday.

A format that survives: the date on one line; one line per trade or visitor; one line per delivery; one line per inspection; a "decided" line; a "problems" line; a "tomorrow" line. If you are rarely on site, the daily log is written by whoever is, and sent to you; ask the contractor whether they keep one, and ask to see it. If nobody keeps one, that is a fair thing to ask for.

The daily log, the decision log, the issue log (Module 10) and the look-ahead are four documents, and that is fine. They answer four different questions: what happened, what we decided, what is wrong, and what is next.

8. See it: a two-week look-ahead for the Birch Lane addition, with one conflict See it

Where the project stands

It is Friday, October 9, 2026. Framing is nearly done; Tollan's crew finishes the roof and wall sheathing and sets the last headers next week, and the roofer follows with underlayment and flashing at the tie-in. Nine windows are due to ship the week of October 12 and go in the week after. Once the building is dried in, the interior rough-ins follow, and then the framing inspection. In this fictional jurisdiction, the building department inspects framing after the rough-ins have passed, and will not inspect an addition that is not dried in; inspections are requested at least 48 hours ahead.

The look-ahead as issued on Friday, October 9

The conflict

On Monday, October 12, the supplier emails: the nine windows will ship two weeks late, on October 26. Without them the building cannot be dried in, and in this jurisdiction the framing inspection cannot be requested until the rough-ins pass and the addition is weathertight. As written, the look-ahead's controlling item has just moved: a week if the windows can go in the week they arrive, two if they cannot. The openings are open to the weather, the insulator is booked for the week after the inspection, and the next progress payment under Tollan's contract is tied to the dry-in milestone.

What the coordinator does, in order

1. Get the facts in writing, and ask the recovering question. The owner replies to the supplier the same morning: confirm the new ship date in writing, and can any of the nine units ship earlier? (Answer, in writing by Tuesday: October 26 for all nine; nothing ships early.) The issue log opens item I-01 with the email's date and a photo of the openings.
2. Ask the building department, do not assume. A call to the inspection desk, confirmed by email: can framing be inspected before dry-in, with the rough-ins following? (In this fictional jurisdiction: no; framing is inspected after the rough-ins pass and the building is dried in.) The answer goes in the issue log so nobody re-asks it in three weeks.
3. Price the options, then decide, and record the decision. Tollan proposes closing the two large openings with temporary plywood and wrapping the rest, so the roofer and the interior rough-ins can proceed; the owner asks what that costs ($380, time and materials) and whether stock windows could be substituted for the two large openings instead (three-week lead anyway, and mismatched sightlines with the other seven). On Tuesday, October 13, the owner decides with Tollan: accept the slip, temporary closure, re-sequence the interior rough-ins forward. It is decision D-01 in the decision log, confirmed by email that day; the closure labor is change order CO-02, signed October 14.
4. Re-sequence what does not depend on the windows. The roofer's tie-in proceeds. The electrician starts Wednesday as planned, once the owner decides the island outlet and sconce locations on October 13 (a decision that was due anyway). The plumber and the heating contractor stay on the week of October 19 under the finished roof. The tub model is confirmed October 16 (D-02) and the tub arrives October 17, uncrated and checked before the receipt is signed (I-03). Nothing that could have moved forward is left waiting for the windows.
5. Tell the downstream trades now. The insulator hears on October 14, not on the day the inspection fails to happen, that the date has moved; asking in October for a slot in the week of November 9, with a warning that it could be a week later, keeps them.
6. Protect what is now exposed longer. The tarps and the plywood are checked after each storm; after wind on October 16 the owner walks the exterior and photographs every opening.
7. Reissue the look-ahead on October 14 to everyone, with the changed dates in one email, and name the new controlling item: the windows' arrival on October 26 and the inspection the week of November 2, on the assumption, confirmed with Tollan, that nine windows can be set and flashed in the week they arrive; if they arrive late in the week, the inspection moves to the week of November 9. At the site meeting on Monday, October 19, the standing items pick all of this up: the slip and its cause under progress, D-01 and CO-02 under decisions and changes, the moved dry-in payment under budget, and the actions with names and dates (Tollan: revised look-ahead by October 20; owner: confirm the heating equipment's ship date by October 21; electrician: finish rough-in by October 23). The notes go out that evening.

The result: the windows are still two weeks late, and the inspection moves with them. But the rough-ins are done when the windows arrive, the insulator is still booked, the openings have been looked after through a windy week, the extra cost is one signed change order, and every person affected heard the new dates from the coordinator on the day they were known. Coordination does not make deliveries arrive; it limits what a late delivery costs.

The informed-homeowner version of this story is shorter and no less important. On Monday the contractor calls: "Windows slipped two weeks; we'll board the big openings and keep the rough-ins moving." The owner's questions are the seven steps above in question form: Is the new date in writing? Did you ask the department whether framing can go first? What does the closure cost, and is there a change order? What proceeds anyway? Have the insulator and the drywall crew been told? What is exposed, and who checks it after a storm? When do I get the new look-ahead? A contractor who has good answers is doing the job. One who is irritated by the questions is telling you something too.

9. Practice: your look-ahead and your meeting agenda Practice

Time: about 45 minutes for the first version; an hour a week after that. Open the dependency map and look-ahead schedule and the meeting agenda and notes. The look-ahead tool's example rows are the Birch Lane two weeks above, and the meeting notes and logs tools carry the same story.

1. Pick the two weeks. If your project is underway, the next two weeks. If it is not, pick the two weeks around the inspection you understand best from Module 5 (rough-in and framing for most projects) and build them as a rehearsal.
2. One row per trade-day block. For each: the trade, confirmed or not (and how you will confirm), the prerequisites and their status, the decisions due with a name and a date, the materials that must be on site and who receives them, and the inspection the work leads to with the day you must request it.
3. Name the controlling item for the two weeks, and write what moves if it slips.
4. Pull the decisions-due column into your selection log (Module 8) and check that the two agree.
5. Build the agenda in the meetings tool from the standing items in section 3, and fill the decisions, deliveries, inspections and RFIs from your look-ahead. If you have a contractor, send it to them as "the things I would like to cover in our weekly check-in."
6. Write tomorrow's daily log entry, even if tomorrow is a rehearsal, so the format exists before the first real day.

Then check your look-ahead against the criteria in Check your work.

10. Your project Your project

11. Check your work Check your work

Criteria

• Every row in the look-ahead says whether the trade is confirmed, and how; no row relies on a phone call from three weeks ago.
• Every row lists its prerequisites with a status, the decisions it needs with a decider and a date, and the materials it needs with a receiver.
• Every inspection has a request day written next to it, at least the lead time your department requires before the inspection day.
• The controlling item for the two weeks is named, with what moves if it slips.
• The meeting agenda has the standing items, and the notes format has an action list with names and dates.
• A decision log, an issue log and a daily log exist, even if nearly empty, and you know which question each answers.

Worked example: one look-ahead row, done fully

Common mistakes

• Listing tasks as if listing confirmed them. A row on a look-ahead is a plan; a written reply from the trade is a confirmation. Mark the difference.
• Forgetting the inspection request lead time. Work finished on Friday is not inspected on Monday unless someone called on Wednesday.
• Putting the owner's decisions on the owner's calendar instead of the trade's. The decision due date is the day before the trade needs it, not the day you feel ready.
• Making decisions by text and not restating them. One written channel for decisions; everything else gets restated there.
• Letting a change proceed on a handshake because the trade is standing there and the signature would take a day. The day is cheaper than the invoice argument.
• Deciding a design or approval question yourself because the designer is slow. Chase the designer; do not replace them.
• Telling a trade how to do their work. Ask questions, photograph, escalate. Means and methods are theirs.

What is still unresolved after this module

• Your building department's inspection request lead time and whether partial inspections are ever possible: ask, and record it in the verification list.
• Whether your contract has a delay clause and what notice it requires.
• Whether you are, or could become, an employer under your state's law if you hire anyone directly, and what your homeowner's policy covers on a construction site: labor agency, insurance agent, adviser.
• Working-hours limits in your jurisdiction and under any HOA or condominium rules.
• Whether lead or asbestos rules affect your house and the trades you hire.

12. Knowledge check and scenario

Before you move on

• I built a two-week look-ahead (real or rehearsal) with every row marked confirmed or not, and prerequisites, decisions, materials and inspections filled in.
• I named the controlling item for those two weeks and wrote down what moves if it slips.
• I built a site meeting agenda with the standing items and a notes format with an action list, and (if I have a contractor) asked for a weekly check-in.
• I set up a decision log and a daily log, chose one written channel for decisions, and told the people I work with what it is.
• I added to my verification list: inspection request lead time, working-hours limits, lead and asbestos questions for my house, and (if I might hire anyone directly) the employer and insurance questions for my state.
• I can say, for a design question, an approval question and a contract question, who decides, and I know the course is not on that list.
