Should Your Site Records Include the Allocation Sheet?

The Allocation Question

Every construction project tracks resources. Timesheets capture hours worked. Plant returns track equipment on site. But ask a simple question: which resources worked on which activities today? The data falls apart.

That's the allocation gap, and it's costing contractors money on every project with variations, disruption, or claims.

What Allocation Sheets Capture

An allocation sheet connects resources to activities. Not just that 20 operatives worked today, but that:

• 8 operatives worked on the drainage variation in area C
• 6 operatives continued with planned foundation works
• 4 operatives were deployed on the access ramp instructed last week
• 2 operatives dealt with the defect rectification from phase 1

This granularity transforms commercial recovery. Without it, you're asking clients to trust your retrospective estimates. With it, you have contemporaneous evidence of actual resource deployment.

Why This Matters Commercially

Consider a typical variation claim. The client instructed additional earthworks. You completed them. Now you're valuing the variation.

Without allocation sheets: You estimate the labour required based on what "should have" been needed. The client disputes your estimate. You have no contemporaneous records proving actual deployment. Settlement ends up at 60% of your claimed value.

With allocation sheets: You have daily records showing exactly which operatives worked on the additional earthworks, for how many hours, over what period. The client can challenge your rates, but they can't challenge the quantum of resource deployed. Settlement achieves 90%+ of claimed value.

The difference between 60% and 90% recovery on a £100K variation is £30K. Multiply that across a project's variations, and allocation sheets become one of your most valuable commercial tools.

The Daily Discipline

Allocation sheets only work if they're completed daily. Retrospective allocation is guesswork dressed as record-keeping. It doesn't carry the same evidential weight, and clients know it.

The discipline required:

• Morning: Planned allocation based on daily brief and programme
• During shift: Adjustments as resources move between activities
• End of shift: Confirmation of actual deployment, signed off by supervisor

This takes 10-15 minutes per day. The commercial value recovered justifies hours of effort, let alone minutes.

What Good Allocation Sheets Include

Essential elements for commercially useful allocation sheets:

Resource Identification

Not just numbers, but specific resources. "J. Smith, Groundworker" not just "1 x Groundworker." Specific identification allows cross-reference with timesheets and prevents double-counting.

Activity Reference

Link to programme activities, work package numbers, or variation references. "Drainage works Area C" might be meaningful today, but six months later when building a claim, you need explicit connections to defined scope items.

Location

Where on site the work occurred. Grid references, chainage, or area descriptions that allow resources to be tied to specific locations where variations applied.

Hours

Start and end times for each activity allocation. Total hours should reconcile with timesheets, providing cross-validation.

Authority

Who authorised deployment, especially for variation works. "Deployed per PM instruction 15/03" creates the connection between instruction and response that supports claims.

Integration with Other Records

Allocation sheets don't stand alone. They form part of a record ecosystem:

• Timesheets: Total hours should match allocation totals
• Daily diaries: Should reference allocation patterns and any significant redeployments
• Plant returns: Equipment allocation should complement labour allocation
• Progress records: Output achieved should correlate with resources allocated

When these records align, they create a consistent narrative that's difficult to challenge. When they conflict, they undermine each other's credibility.

Common Mistakes

Allocation sheets fail for predictable reasons:

Too Generic

"General works" or "various activities" provides no commercial value. If you can't name the activity, you can't link the resource to a recoverable item.

Retrospective Completion

Sheets completed weekly from memory lack the specificity and credibility of daily records. Clients and adjudicators recognise the difference.

No Variation Linkage

Resources deployed on variation works but not flagged as such. When it comes to valuation, there's no record distinguishing variation resources from planned resources.

Inconsistent Format

Different supervisors using different formats, making consolidation and analysis difficult. Standardisation matters for systematic use.

Technology's Role

Digital allocation tracking can address many of these challenges. Drop-down activity lists ensure consistent coding. Mandatory fields prevent incomplete records. Automatic timesheet reconciliation catches errors. Integration with commercial systems enables direct use in valuations.

But technology only helps if people use it properly. The cultural discipline of daily allocation, accurate recording, and consistent completion remains essential regardless of the tools.

What This Means for Your Projects

Should site records include allocation sheets? Absolutely. The real question is how to capture allocation data effectively.

The cost is minimal: 10-15 minutes daily from supervisors who already know where resources worked. The benefit is substantial: defendable claims, credible valuations, and recovery rates that reflect actual entitlement rather than negotiated compromise.

If you're not capturing allocation data today, start tomorrow.

Hours sit with the diary

A site record without labour and plant is a narrative. Keep the allocation with the site diary that shift. Rosie reads those lines against NEC4 so attendance is not offered as the cost.
