If you lead accounting and finance for a mechanical, electrical, and plumbing (MEP) or HVAC contractor serving data center projects, a slipped interconnection date is not just the general contractor’s (GC) problem. It becomes your problem when the delay affects purchase orders, labor plans, and billing schedules. When a major equipment package or power milestone moves, the baseline changes for every trade tied to installation, testing, commissioning, and turnover.
The GC or owner may manage the master schedule, but your company still carries the resulting purchase commitments, storage costs, retainage, and change order exposure. If those obligations are not dynamically reflected in work in progress (WIP), a profitable-looking project can consume cash and erode margin before finance sees the full impact.
The Same Disruptions Reach Trade Contractors
Data center MEP contractors face the same two disruptions as GCs: exceptionally long equipment lead times and power milestones that shift after the project baseline is set. The trade contractor has less control over either condition while remaining responsible for protecting its own margin. According to Wood Mackenzie research reported by Data Center Knowledge, substation transformer lead times increased from roughly 140 weeks in 2023 to more than 160 weeks in 2026, while switchgear timelines remained closer to one year.
Large power transformers, medium-voltage switchgear, generators, chillers, and air-handling equipment may need to be reserved before the final design is locked. Procurement frequently begins before the subcontract is fully executed because waiting can jeopardize the schedule. Pre-contract procurement may protect the schedule, but the cost commitment begins when the purchase order is issued, not when the invoice arrives.
Committed Cost Exposure Starts Before Accounts Payable (AP)
A WIP schedule that excludes open commitments cannot show the full financial position of a long-lead package. When committed costs are not captured as purchase orders are placed, estimated cost to complete remains understated until the supplier submits invoices. This gap can:
- Overstate projected gross profit.
- Understate near-term cash requirements.
- Delay recognition of a forecast loss.
- Leave finance defending a WIP position that no longer matches the project team’s commitments.
For data center MEP contractors, purchase commitments should be incorporated into the WIP forecast as soon as they are made.
Power Delays Make the WIP Baseline Obsolete
Construction WIP reporting depends on current assumptions about total cost, percent complete, earned revenue, and remaining margin. A single power delay can quickly make all four assumptions outdated. Electrical contractors may have equipment in fabrication to support energization dates that later move by months. Mechanical contractors may have labor and deliveries sequenced around turnover dates that no longer apply. Storage, escalation, extended supervision, remobilization, and lost productivity can begin accumulating immediately.
A spreadsheet can help you recalculate the numbers, but spreadsheets alone rarely resolve reporting gaps among purchasing, field operations, project management, and accounting. By the next monthly WIP review, finance may still be working from assumptions the project team has already revised.
Design Changes Create Additional MEP Exposure
Rising rack densities and evolving cooling requirements can alter electrical distribution, mechanical capacity, controls, piping, equipment layouts, and installation sequencing after the original package was priced. A shift toward liquid cooling can require a revised mechanical and electrical scope during construction. If your budget is not updated to reflect those changes, prior forecasting will no longer represent the projected project scope. Left unaddressed, revised scope, anticipated costs, and change order status can let margin erosion go unnoticed.
Change Order Recovery Depends on the Record
Scope creep and limited visibility into field productivity become financial problems when an MEP contractor has to support a change order. You may have limited control over changes initiated by the owner or GC, but you still have to document any financial impact. These events can trigger cost escalation, productivity losses, extended supervision, storage costs, and additional mechanical and electrical work. The strength of a change order request depends on timely supporting documentation. You must document:
- When the condition changed.
- Which commitments and activities were affected.
- How the additional cost developed.
- Whether the change is pending, approved, or disputed.
If daily reports, labor data, purchase orders, change events, and job cost data sit in separate systems, reviewers may see legitimate costs as unexplained overruns, increasing the risk of disputes and back-charges.
Field and Finance Need the Same Project Information
Disconnected field and office communication, delayed invoicing, and incomplete retainage information compound each other. Field teams need a current view of budgets, commitments, changes, and remaining costs; accounting needs timely labor, material, purchasing, and progress data. When information arrives late or incomplete, the WIP review becomes an exercise in reconciling discrepancies rather than evaluating project performance. Labor constraints make the lag more consequential. DPR Construction’s Q4 2024 Market Conditions Report found that 77% of contractors reported increased difficulty filling craft positions in 2024. As a result, MEP contractors have less flexibility to shift crews or absorb resequencing. If finance does not see a productivity hit until the next WIP meeting, the window to document, price, or mitigate it may already have closed.
What an Integrated Project and Accounting System Needs to Do
Faster month-end reporting alone will not solve these problems. Purchase commitments, field activity, forecast changes, and accounting transactions need to remain connected throughout the project. Data center MEP contractors need systems that capture purchase orders and subcontracts as commitments, connect them to the job forecast, and keep billing, WIP, change orders, and field activity aligned. Sage for Specialty Contractors brings together four connected applications: Sage Intacct Construction for construction accounting, Sage Construction Management for project management, Sage Field Operations for daily field reporting, and Sage Intacct Inventory Management for materials and inventory tracking. Together, these applications support:
- Job costing and billing.
- WIP reporting.
- Purchasing and commitments.
- Vendor compliance and purchase-order controls.
When contract setup, budgets, cost controls, and operational data remain aligned, field, project, and finance teams can evaluate performance using the same information.
Capture the Commitment When It is Made
Sage Construction Management can track committed and anticipated costs across RFP packages, purchase orders, and bills, allowing finance to monitor long-lead commitments for transformers and switchgear well before supplier invoices arrive. When connected with Sage Intacct Construction, those commitments can be compared with the current budget and contract value. Finance can evaluate the cash-flow and margin effects before the invoice reaches AP, while project managers gain current financial information without waiting for a special report. The TeamLink Portal can extend selected project information to GCs, owners, and other collaborators. This project record can support change order review by documenting when a condition changed and how the change affected cost.
Customer Example: C1S Group
Contractors can also achieve this visibility by integrating Sage Intacct Construction with an existing project management platform. C1S Group connected Sage Intacct Construction and Procore so project managers could access current commitments, job costs, and change orders without waiting for accounting reports. The integration removed a reporting bottleneck and gave project teams timely visibility into job performance. Although each contractor’s workflow differs, project managers still need timely visibility into whether new commitments and changes are reducing forecasted margin.
MEP Contractors Need a Current WIP Forecast
When power delivery, equipment schedules, or design requirements shift, MEP contractors absorb the effects through commitments, labor plans, billing, and change orders. Although they may not control the master schedule, their WIP forecasts must reflect new commitments, revised sequencing, and pending changes as those conditions develop.
