Why Most Project Schedules Fail
Every contractor starts a project with a schedule. And almost every project falls behind that schedule. The reason is simple: traditional project schedules are too rigid and too long-range to account for the reality of construction. Weather changes, materials get delayed, subs no-show, clients change their minds, inspections get pushed back.
Malcolm MacInnes of MGM GC shared his scheduling approach on the First Shift Podcast, and it centers on a concept that top general contractors have used for decades: the two-week look-ahead.
What Is a Two-Week Look-Ahead?
A two-week look-ahead is a rolling, detailed schedule that covers the next 14 days of work on a project. Unlike your master project schedule, which might span 6 months, the look-ahead is granular, actionable, and updated weekly.
Here is what it includes:
- Daily task assignments. Who is doing what, on which days, and in what order.
- Material requirements. What needs to be on-site and when. This flags procurement issues before they cause delays.
- Subcontractor coordination. When each sub needs to be on-site, what they need from you, and what needs to be completed before they arrive.
- Inspection milestones. When inspections need to be called and what needs to be ready.
- Decision points. Any client decisions, design clarifications, or approvals needed in the next two weeks.
- Potential conflicts. Where trades overlap, where weather might be a factor, or where a delay in one task cascades into others.
Why Two Weeks Is the Sweet Spot
One week is too short. You do not have enough runway to solve problems before they hit. If a material delivery is delayed by three days, a one-week look-ahead gives you no time to adjust.
One month is too long. Too much changes in a month. You end up spending time planning activities that will inevitably shift, which wastes effort and creates false confidence.
Two weeks is just right. It gives you enough visibility to catch problems early while staying close enough to reality that your plan actually holds. Most variables in construction, weather, material lead times, sub availability, can be predicted with reasonable accuracy within a 14-day window.
How to Build Your Two-Week Look-Ahead
Step 1: Start with Your Master Schedule
Pull the relevant section from your overall project timeline. What is supposed to happen in the next two weeks according to the master schedule?
Step 2: Reality-Check Every Item
Go through each task and ask:
- Do we have the materials on-site or confirmed for delivery?
- Is the crew or subcontractor confirmed and available?
- Is the prerequisite work actually complete?
- Are there any inspections that need to happen first?
- Has the client made the necessary decisions?
This step is where most delays get caught two weeks early instead of the morning they happen.
Step 3: Build the Daily Breakdown
Assign specific tasks to specific days. Be realistic about production rates. If your crew can frame 200 square feet of wall per day, do not schedule 400. Account for setup time, cleanup, breaks, and the inevitable interruptions.
Step 4: Identify and Communicate Risks
Flag anything that could derail the plan. Then communicate those risks to the relevant people:
- Call the supplier about the delivery that is cutting it close.
- Confirm with the sub that they are locked in for Thursday.
- Email the client about the tile selection they have not made yet.
- Check the weather forecast and have a rain day plan.
Step 5: Review and Update Weekly
Every Monday (or Friday, depending on your preference), update the look-ahead. Roll it forward, add the next week, adjust for what actually happened, and repeat the process.
The Compound Effect of Consistent Scheduling
Malcolm's point on the First Shift Podcast was that the look-ahead is not just a scheduling tool. It is a communication tool, a risk management tool, and a leadership tool all in one.
When you share the two-week look-ahead with your team, your subs, and your client, everyone knows what is happening and what is expected of them. Surprises go down. Accountability goes up. And projects run smoother.
Contractors who use the two-week look-ahead consistently report:
- 20 to 30% fewer schedule delays. Because problems get caught early.
- Better subcontractor relationships. Because subs know exactly when they are needed and what will be ready for them.
- Happier clients. Because they see a well-organized contractor who communicates proactively.
- Less stress for the team. Because everyone knows the plan and can prepare accordingly.
Tools to Make It Easier
You can run a two-week look-ahead with a whiteboard and a marker. But digital tools make it easier to share, update, and track:
- Buildertrend or CoConstruct. Full construction project management platforms with look-ahead scheduling features.
- Monday.com or Asana. General project management tools that work well for smaller contractors.
- Google Sheets. Free, shareable, and good enough for most small to mid-size projects.
- A simple spreadsheet template. Columns for date, task, responsible party, materials needed, status, and notes.
Start This Week
Pick your most active project. Sit down for 30 minutes and map out the next two weeks in detail. Share it with your team and your client. Do it again next week. Within a month, you will wonder how you ever ran projects without it.
