Concrete Pour Day Playbook for Commercial Projects: A GC & EC Guide to Zero-Delay Pours in Middle Tennessee

Concrete pour day is where planning meets reality. For general contractors (GCs) and electrical contractors (ECs), it’s also one of the highest-risk days on the schedule: multiple crews converge, inspections and testing have to happen at the right time, and weather or access issues can derail the entire day.

This guide is a practical “pour day playbook” you can use on commercial projects across Middle Tennessee. It’s built around one goal: a clean, safe, on-time pour with no surprises.

At Halemeyer Group, we specialize in commercial foundations, slabs, site work, light pole bases, and trenching for utility lines. We’ve learned that the best pours aren’t the ones with heroic last-minute fixes—they’re the ones where the team runs a repeatable process.

Why Pour Day Performance Matters (More Than People Think)

Concrete is often on the critical path. If the pour slips, downstream trades slip. If the pour goes poorly, you risk rework, schedule compression, and quality disputes.

Common “hidden” impacts of a bad pour day include:

• Lost schedule float that never comes back

• Idle labor for ECs and other trades waiting on slab access

• Overtime to recover the schedule

• Finish quality issues that create callbacks (and owner dissatisfaction)

• Safety exposure from rushed work, traffic congestion, and poor site control

A strong pour day process protects your schedule, your margin, and your reputation.

The 72–48–24 Hour Countdown (Pre-Pour Checklist)

If you want pour day to run smoothly, most of the work happens before the first truck arrives. Here’s a countdown framework you can reuse.

72 Hours Before the Pour: Confirm the Big Rocks

Schedule and scope alignment

• Confirm pour date/time, placement sequence, and estimated duration

• Confirm slab thickness, mix design, PSI, slump, air, fiber, and any admixtures

• Confirm finishing requirements (broom, hard trowel, burnished, exposed aggregate, etc.)

• Confirm jointing plan (sawcut timing, spacing, isolation joints)

Site readiness

• Verify subgrade prep is complete and meets spec (compaction, proof roll, moisture)

• Confirm vapor barrier, insulation, and base stone are installed per plan

• Confirm forms are set, braced, and elevations verified

• Confirm rebar/WWR placement, chairs, laps, and cover

Coordination with ECs (critical)

• Confirm all sleeves, conduits, stub-ups, and blockouts are installed and secured

• Confirm any grounding requirements (ufer ground, rebar bonding) are complete

• Confirm trenching/backfill is complete and compacted where required

Permits and inspections

• Confirm required inspections are scheduled (rebar, underground, forms)

• Confirm testing lab availability (cylinders, slump, air, temperature)

48 Hours Before the Pour: Lock Logistics

Concrete supply and equipment

• Confirm plant booking and truck count

• Confirm pump truck booking (if needed) and hose length/access

• Confirm backup plan if a pump goes down or plant delays occur

Weather plan (Middle Tennessee reality)

• Check forecast for rain, wind, heat, and cold

• Confirm hot/cold weather protection plan (blankets, heaters, wind breaks, fogging)

• Confirm who makes the go/no-go call and by what time

Site logistics

• Establish truck route, staging area, and washout location

• Confirm access is stable (mud control, stone, turning radius)

• Confirm laydown areas are clear of pour footprint

24 Hours Before the Pour: Final Verification

• Walk the pour area with GC + concrete foreman + EC lead

• Verify all penetrations are in the right place and properly braced

• Confirm edge forms, keyways, dowels, and embeds

• Confirm finishing crew size matches pour size and weather

• Confirm lighting plan if the pour may run late

• Confirm safety plan: traffic control, PPE, spotters, exclusion zones

Pour Day Roles: Who Owns What?

Pour day gets messy when responsibilities are vague. A quick role map prevents confusion.

GC responsibilities (typical)

• Overall site control and safety coordination

• Confirm inspections are passed and documented n- Confirm access and logistics (routes, staging, washout)

• Coordinate other trades and keep non-essential traffic out

EC responsibilities (typical)

• Verify conduit/sleeves/stub-ups are installed per plan and secured

• Provide a point person for last-minute field questions

• Confirm no live hazards in the pour zone

Concrete subcontractor responsibilities (Halemeyer Group focus)

• Placement plan, crew staffing, and finishing execution

• Quality control during placement (consolidation, strike-off, finishing)

• Coordination with testing lab and mix adjustments as allowed

• Protecting concrete during cure and advising on sawcut timing

The key is not “who’s at fault” later—it’s clarity before the first truck.

The Pour Day Timeline: A Practical Run-of-Show

Here’s a simple run-of-show you can adapt for most commercial slabs and foundations.

1) Pre-Start Huddle (30–45 minutes before first truck)

• Review pour sequence and expected truck spacing

• Confirm safety zones and spotters

• Confirm where the pump will sit and where trucks stage

• Confirm finishing plan and jointing plan

• Confirm testing plan and who receives results

2) First Truck: Verify Mix Before You Commit

Before you place 10 yards, confirm:

• Ticket matches spec (PSI, mix ID, admixtures)

• Slump/air/temp testing is performed per spec

• Any water additions are controlled and documented

If something is off, fix it early—bad concrete placed fast is still bad concrete.

3) Placement: Keep the System Moving

Best practices that prevent delays:

• Maintain consistent truck spacing to avoid cold joints

• Keep the pump line moving with clear communication

• Use proper consolidation (vibration) especially at edges and around embeds

• Protect conduits and stub-ups from movement during placement

4) Finishing: Timing Is Everything

Finishing is where schedule pressure can create quality problems.

• Don’t close the surface too early (traps water, increases scaling risk)

• Match finishing method to spec and use case (warehouse vs. exterior flatwork)

• Plan for weather: heat accelerates set; cold slows it

5) Joints and Sawcutting: Prevent Random Cracking

Cracking is normal; uncontrolled cracking is the problem.

• Confirm joint layout before placement

• Protect isolation joints at columns, walls, and penetrations

• Plan sawcut timing based on set and conditions

6) Cure and Protection: The Pour Isn’t Done When You Leave

Curing is performance.

• Apply cure compound per spec or wet cure as required

• Protect edges and high-traffic areas

• Set rules for when trades can access the slab

The EC-Specific Risk Zone: Sleeves, Stub-Ups, and Underground

On commercial projects, EC coordination can make or break pour day.

Common EC-related pour day issues

• Stub-ups shift during placement and end up out of wall lines

• Conduit floats because it wasn’t tied down

• Missing sleeves discovered after forms are set

• Underground not compacted, leading to settlement and slab issues

EC best practices that prevent pour day surprises

• Provide a final “penetrations map” to the GC and concrete foreman

• Mark critical stub-ups with paint and offsets

• Secure conduits with stakes/ties to prevent movement

• Ensure trench backfill is compacted and verified where required

When ECs and concrete crews coordinate early, you avoid the worst kind of fix: core drilling and patching after the fact.

Weather in Middle Tennessee: What to Plan For

Weather is one of the biggest drivers of pour day delays.

Rain

• Confirm subgrade protection plan (plastic, pumps, rework expectations)

• Avoid placing on saturated subgrade

Heat

• Plan early morning pours

• Consider approved set retarders

• Keep finishing crew sized appropriately

Cold

• Confirm minimum placement temperatures

• Plan blankets/heaters and protect from freezing

• Extend cure protection and adjust schedule expectations

Quality Control That Prevents Rework (and Arguments)

A clean QC process protects everyone.

• Document pre-pour conditions (photos of subgrade, rebar, embeds)

• Keep all batch tickets and test results organized

• Record start/finish times, weather conditions, and any mix adjustments

• Confirm flatness/levelness requirements early if the slab is spec’d (FF/FL)

Rework is the most expensive schedule delay. Good documentation reduces disputes and speeds decisions.

Pour Day Red Flags (When to Pause and Fix)

If you see these, it’s usually cheaper to pause than to push through:

• Access is unstable and trucks are getting stuck

• Subgrade is pumping or saturated

• Missing sleeves/embeds discovered late

• Mix is consistently out of spec

• Finishing crew is undersized for the pour size and weather

• No clear washout plan (environmental and safety risk)

A short pause can prevent a long remediation.
