How the EPC Model Compresses Schedule on Industrial Projects
In a strict design-bid-build sequence, procurement doesn’t start until engineering is complete, and construction doesn’t start until procurement has delivered materials to the site. Each phase waits for the one before it to finish and for a new contract to be bid and awarded. On a large industrial project, that sequencing alone can add months to a timeline that has nothing to do with the work’s actual complexity —it’s the cost of the handoffs themselves.
Why Sequential Delivery Takes Longer Than the Work Requires
Design-bid-build’s core assumption is that each phase must be fully finished and competitively bid before the next begins. That protects against certain risks, but it also guarantees that no work on procurement or construction planning happens until engineering is 100% complete — even for portions of a project where the design is essentially finalized early and just waiting on sign-off for the rest.
- Procurement can’t begin until a full engineering package is issued and a new contract is bid
- Construction planning starts from scratch once a general contractor is separately selected
- Long-lead equipment gets ordered later than necessary, extending the critical path
- Each bidding cycle between phases adds administrative time with no construction progress
How an Integrated EPC Model Runs Phases in Parallel
Because engineering and procurement operate under the same project team at Wikota Design & Construction and Fabrication, long-lead materials and equipment can be identified and ordered as soon as the relevant design elements are finalized — without waiting for the entire engineering package to be complete or for a separate procurement contract to be bid.
With in-house fabrication at Wikota’s Brookshire, Texas facility, shop fabrication of skids, structural components, and pressure equipment can proceed in parallel with site preparation and civil work in the field, rather than waiting for construction mobilization to begin fabrication planning.
Because Wikota’s construction management team works within the same project structure as engineering, site logistics, sequencing, and safety planning can begin well before construction officially starts — using design information the team already has direct access to, rather than waiting to receive and interpret a finished design package from an outside firm.
One Schedule, Managed as a Single Critical Path
Perhaps the most direct source of compression: with one project management team overseeing engineering, procurement, and construction, the project schedule is managed as a single integrated critical path rather than three separate schedules that have to be reconciled against each other at each handoff.

Start the ConversationWhat Schedule Compression Does Not Mean
Compressing schedule through integrated delivery is not the same as rushing engineering or skipping quality steps. Wikota’s welding is still performed to AWS D1.1 standards with CWI-certified inspection and NACE- and NDT-certified quality review regardless of schedule pressure. The time saved comes from eliminating the administrative and sequencing delays between phases — not from reducing the technical rigor applied within each phase.
When Schedule Compression Matters Most
This model provides the most value on projects with a hard operational start date — a facility expansion tied to a supply contract, a new build that needs to be online before a regulatory deadline, or any project where the cost of delay exceeds the cost of the work itself. For owners across the Gulf Coast, Permian Basin, and Mid-Continent facing that kind of timeline pressure, integrated EPC delivery is often the difference between hitting a startup date and missing it.
Frequently Asked Questions — Schedule Compression
How much schedule compression is realistic with an integrated EPC model?
It varies by project scope and complexity, but eliminating separate bidding cycles between engineering, procurement, and construction phases commonly recovers weeks to months compared to strict design-bid-build sequencing.
Does schedule compression increase project risk?
Not when phases are genuinely integrated under one project management structure with shared visibility into design, procurement, and field status. The risk in overlapping phases comes from poor coordination, which is exactly what an integrated EPC model is structured to prevent.
Can Wikota compress schedule on a project already in progress with another contractor?
It depends on which phase the project is in and how much design or procurement work is already committed. Wikota's project managers can evaluate a project already underway during an initial consultation to determine where schedule recovery is realistic.
