What Is Project Phasing?

Project phasing is the practice of dividing a large countertop order into multiple sequential fabrication and delivery releases, each timed to align with the construction schedule. Rather than fabricating and delivering an entire project’s worth of countertops in a single batch, phased delivery produces and ships countertops in coordinated groups as each area of the building becomes ready for installation.

On a 10-story office building, for example, phased delivery might produce and deliver countertops two floors at a time, starting with the lowest floors and working up as construction progresses. On a multi-building campus, phasing might align with building completion sequences.

For contractors managing large commercial projects, phasing is not just a logistical convenience — it is a schedule management strategy that reduces risk, improves quality, and keeps the project moving forward even when earlier phases are still being installed.

Why Phasing Matters for Commercial Projects

Construction Schedules Are Sequential

Commercial buildings are not built all at once. Construction proceeds in a logical sequence — typically bottom to top, core to perimeter, wet trades before dry trades. Countertop installation falls late in the finish sequence, after cabinetry, after rough plumbing, and often after painting.

On a large project, the first floor might be ready for countertop installation months before the top floor. Fabricating all countertops at once means the upper-floor tops sit in storage for weeks or months, while the lower-floor tops may be needed immediately.

Storage Space Is Limited and Expensive

Job site laydown space is one of the most contested resources on a commercial project. Storing hundreds of countertop pieces on-site creates problems:

• Space consumption — countertops require flat, protected storage that competes with other trades’ materials and work areas
• Damage risk — every day a countertop sits on a job site before installation is another day it can be scratched, chipped, water-damaged, or broken by other trade activity
• Handling damage — countertops that must be moved multiple times to accommodate other work are more likely to be damaged
• Theft and vandalism — materials stored on-site for extended periods are vulnerable to theft, particularly on urban projects

Dimensions May Not Be Final

On large projects, final countertop dimensions for upper floors or later buildings may not be available when earlier floors are ready for installation. Phasing allows the fabricator to work with confirmed dimensions for each release rather than committing to dimensions that might change.

This is particularly important when field conditions reveal deviations from architectural drawings — out-of-square walls, varied cabinet installations, or design changes during construction. Later phases can incorporate actual field measurements, resulting in better-fitting countertops.

How Phased Delivery Works

Phase Planning

Phasing starts during the preconstruction or submittal phase. The contractor and fabricator collaborate to establish:

• Number of phases — typically determined by the number of floors, buildings, or distinct project areas
• Phase sequence — which areas get countertops first, second, third
• Phase quantities — how many countertop pieces (or linear feet) per phase
• Target delivery dates — when each phase needs to arrive on-site
• Dimension submission deadlines — when the fabricator needs confirmed dimensions for each phase

This information is typically documented in a phasing schedule that becomes part of the project’s overall procurement plan.

Dimension Submission by Phase

For each phase, the contractor submits confirmed dimensions to the fabricator at a predetermined deadline. Dimensions may come from:

• Shop drawings based on architectural plans (for early phases when field conditions are not yet available)
• Field measurements taken by the contractor after cabinetry is installed (for later phases where field verification is possible)
• Templates created by the fabricator’s templating team (for complex or critical areas)

The dimension submission deadline is calculated backward from the target delivery date, accounting for fabrication lead time, order processing, and a scheduling buffer.

Fabrication and Quality Control

Each phase enters the fabrication queue as an independent production order. The fabricator:

1. Reviews submitted dimensions against approved submittals
2. Programs CNC equipment for the phase’s specific pieces
3. Cuts, edges, and finishes all pieces in the phase
4. Inspects each piece against the shop drawings
5. Labels and stages pieces for delivery or pickup

Delivery and Installation

Each phase is delivered according to the agreed schedule. Delivery coordination includes:

• Delivery timing — countertops arrive when the installation area is ready, not before
• Staging location — where on-site the countertops will be stored between delivery and installation (ideally minimal time)
• Access logistics — elevator availability, hoist schedules, floor access for deliveries
• Installation sequence — the order in which pieces are installed within the phase area

Phasing Strategies for Different Project Types

Multi-Story Buildings

The most common phasing approach for multi-story projects is floor-by-floor delivery. Countertops for floors 1-2 are fabricated and delivered first, followed by floors 3-4, and so on.

Considerations:

• Align phase breaks with the building’s vertical construction sequence
• Account for elevator availability — countertop deliveries compete with other trades for hoist time
• Plan for different countertop specifications on different floors (e.g., executive floors may specify different materials than standard floors)

Multi-Building Campus Projects

Campus projects with multiple buildings phase by building or building group. Each building operates as an independent phase with its own dimension submission deadline and delivery date.

Considerations:

• Building completion sequences may not match building numbering
• Different buildings may have different countertop specifications
• Staging and delivery logistics vary by building location within the campus
• Weather can affect outdoor delivery paths between buildings

Phased Tenant Improvements

In speculative office buildings, countertops for common areas (lobbies, restrooms, break areas) may be ordered first, with tenant suite countertops ordered as leases are signed and build-outs begin.

Considerations:

• Tenant suite requirements are not known at the time of base building construction
• Color matching between base building and tenant phases requires careful material selection from the same production lots when possible
• Long gaps between phases require the fabricator to maintain material availability

Renovation and Occupied Building Projects

Phasing is essential when renovating occupied buildings. Countertops are delivered to match the renovation sequence, which is typically dictated by tenant relocation schedules and operational requirements.

Considerations:

• Delivery windows may be restricted to nights, weekends, or specific hours to minimize disruption to building operations
• Elevator access may be limited during business hours
• Finished areas adjacent to renovation zones must be protected during delivery and installation

Phase Coordination Best Practices

Establish Communication Protocols

Define how the contractor and fabricator will communicate about phase scheduling. This includes:

• Primary contacts on both sides responsible for phasing coordination
• Update frequency — weekly status calls or emails during active phases
• Change notification — how schedule changes are communicated and documented
• Dimension format — agreed format for dimension submissions (CAD files, marked-up drawings, dimension sheets)

Build Buffer Into Each Phase

No construction schedule runs perfectly. Build 3-5 business days of buffer between your target delivery date and the absolute latest date you can accept delivery without impacting the installation schedule. This buffer absorbs minor schedule shifts without triggering emergency rescheduling.

Confirm Material Availability for All Phases

Before committing to a phasing plan, verify that the fabricator can supply the specified materials for every phase over the project’s full duration. A 12-month project with 8 phases needs material availability guaranteed for the entire 12 months, not just the first phase.

If using TFL or solid surface colors, confirm that the fabricator stocks sufficient inventory or can source consistent material across all phases. Color variation between production lots is a real concern on long-duration projects.

Document Everything

Each phase should have documented:

• Confirmed dimensions with date of submission and submitter
• Agreed delivery date and any changes to that date
• Delivery receipt signed by the receiving party
• Punchlist items noted at delivery (damage, shortages, discrepancies)
• Installation completion and acceptance

This documentation protects both parties and provides a clear record for dispute resolution if needed.

Plan for Phase Overlaps

On fast-moving projects, phase N may still be installing while phase N+1 is being fabricated and phase N+2 dimensions are being submitted. This overlap is normal and manageable with proper planning, but it requires all parties to track multiple phases simultaneously.

Common Phasing Problems and Solutions

Schedule Acceleration

When the construction schedule accelerates, phase delivery dates move up. The fabricator needs advance notice to adjust production scheduling. Two weeks of notice is reasonable for shifting a phase date; less than one week creates capacity challenges.

Solution: Maintain regular communication with your fabricator about schedule trends, not just confirmed changes. A heads-up that “floors 7-8 are tracking two weeks ahead of schedule” gives the fabricator time to plan.

Schedule Delays

When construction slows, phase delivery dates push out. This is usually less disruptive to the fabricator (they can reallocate capacity to other projects) but can create material storage issues if countertops have already been fabricated.

Solution: Notify the fabricator as soon as delays are anticipated. Fabricated but undelivered countertops may be storable at the fabricator’s facility for a limited time.

Dimension Changes Between Phases

Field conditions often reveal that dimensions on later floors differ from architectural drawings or from earlier floors. Walls may be in different locations, cabinet installations may vary, or design changes may have been made.

Solution: Always submit actual field-verified dimensions for each phase rather than assuming later phases match earlier ones. The few hours spent verifying dimensions save days of rework if countertops do not fit.

Material Inconsistency Across Phases

Color, texture, or pattern variation between production lots of the same material can create visible inconsistency when countertops from different phases are installed in adjacent areas.

Solution: For areas where consistency is critical, order material for all affected phases from the same production lot. Your fabricator can reserve material from a single lot for the project’s full duration.
