Industrial Electrical Project Delivery: Greenfield, Brownfield, Tie-Ins & Commissioning
What Project Delivery Means as a Managed Capability
Field execution is one part of project delivery. The other parts are what happen before the first cable pull and after the last system test. Pre-construction planning, procurement coordination, QA/QC hold points, commissioning protocols, and handover documentation determine whether the project finishes on schedule, within budget, and with a system that operates as designed.
Wikota Electrical Services manages the full project delivery lifecycle for industrial electrical scopes. Project managers coordinate engineering, procurement, field execution, and commissioning as a connected sequence rather than as separate phases handed off between teams.
Greenfield and Brownfield Builds
Greenfield projects are new facilities built on undeveloped sites. The electrical scope can be planned and sequenced without the constraints of existing systems, which allows the construction schedule to be structured around equipment deliveries and logical installation sequences. Brownfield projects involve working within or adjacent to operating facilities, which introduces outage coordination, temporary power requirements, and live-plant interface procedures that must be planned before work begins.
Tie-Ins, Turnarounds, and Shutdown Execution
Tie-in work connects new systems to operating electrical infrastructure during a planned outage window. The scope requires isolation verification, LOTO procedure development, outage duration planning, and energization step documentation. Turnarounds involve larger-scope maintenance and modification work within a defined shutdown window. Wikota Electrical Services develops detailed tie-in and turnaround plans that are reviewed with the facility operations team before execution begins.
Integrated EPC via Wikota Design & Construction
Projects requiring full EPC delivery can be executed through the Wikota-affiliated platform. Wikota Design & Construction LLC provides engineering and project management, Wikota Fab Solutions provides prefabricated skids and modular assemblies, and Wikota Electrical Services provides field construction, instrumentation, and controls. All three entities operate under coordinated project leadership with shared document management.
Construction Management and QA/QC
Construction management covers schedule development and tracking, submittal management, RFI processing, change control, and daily field coordination. QA/QC hold points are defined in the project quality plan and require documented inspection sign-off before the next phase of work proceeds. Field checklists, material certifications, and inspection and test plan records are maintained throughout construction and included in the closeout package.
Startup, Commissioning, and Handover
Commissioning begins with pre-functional checks that verify installations are complete and ready for energization. Functional testing confirms that each system operates as designed under simulated operating conditions. Startup transitions the system to live operation. Handover documentation includes as-built drawings, test records, equipment certifications, O&M manuals, and warranty information. Training for facility operations personnel is available as part of the handover scope.
Frequently Asked Questions
Greenfield electrical construction takes place on a new site with no existing electrical infrastructure. The work can be planned and sequenced based on equipment deliveries and logical installation order without accommodating operating systems. Brownfield construction takes place within or adjacent to an existing operating facility. The primary differences are outage coordination requirements, the need to protect operating systems during construction, temporary power planning, and the additional safety planning required for work near energized equipment.
A tie-in connects new electrical systems to the operating distribution system during a planned outage window. The scope includes isolation procedure development, LOTO plan preparation, outage duration estimation, energization step documentation, and post-energization testing. A turnaround is a broader planned maintenance and modification event that may include multiple tie-ins along with other electrical maintenance and upgrade work. Both require detailed advance planning and coordination with the facility operations and safety teams.
Quality assurance on an electrical project establishes the standards and procedures that govern how work is performed. Quality control verifies that work meets those standards through inspection and testing. QA/QC hold points are defined stages in the construction sequence where work cannot proceed until an inspection is completed and documented. Examples include cable tray installation inspections before pulling wire, termination inspections before energization, and grounding system tests before equipment is connected.
A startup and commissioning package includes pre-functional checklists confirming installation completeness, functional test procedures for each system, energization plans with step-by-step sequences, test records documenting results, punchlist tracking and resolution, as-built drawing updates, O&M manual compilation, equipment warranty documentation, and operator training materials. The specific deliverables are defined in the project specification and confirmed in the quality plan.
Prefabricated electrical assemblies such as skids, control panels, and modular distribution equipment are built and tested in a controlled fabrication environment while site civil and structural work proceeds in parallel. When the site is ready to receive electrical equipment, pre-tested assemblies can be set and connected rather than built in the field from components. This reduces field labor hours, compresses the electrical installation schedule, and moves quality control testing to a controlled environment where defects are identified before the equipment reaches the site.
