01

Defining the engineering question

Engineering consulting starts by clarifying the decision the client needs to make. Feasibility, concept selection, design review, due diligence, owner-side verification and construction-stage support require different levels of evidence and should not be treated as the same review exercise.

Gokbilge converts project objectives into design criteria, assumptions, interface requirements and decision points so multidisciplinary work can be reviewed against a defined basis rather than personal preference.

02

Multidisciplinary design review

Electrical, mechanical, civil, structural, automation and operational requirements are reviewed together. Load data, equipment footprints, penetrations, cable routes, utilities, access and maintenance clearances are checked across disciplines before conflicts reach procurement or site.

Assumptions, deviations and unresolved interfaces are recorded in a common register with an owner and required decision date.

  • Interface register
  • Decision/action tracker

Owner-side and delivery-side support

Owner-side assignments focus on technical intent, performance, maintainability, lifecycle implications and compliance with the contract. Delivery-side assignments focus on constructability, vendor integration, field constraints and resolution of information gaps without weakening the approved design basis.

The distinction matters because the consultant's responsibility and decision authority should be clear before recommendations are issued or changes are approved.

04

Deliverables and client value

Typical outputs include design-review reports, technical due-diligence notes, basis-of-design comments, interface registers, risk notes, option comparisons and decision recommendations. The purpose is to make complex technical decisions traceable and executable.

Clients gain earlier visibility of design risk and a structured basis for instructing designers, suppliers and contractors.

05

Technical due diligence and option evaluation

When a project is still at investment, tender or concept stage, the engineering question is often whether the proposed solution is complete, buildable and commercially defendable. Gokbilge reviews available studies, design assumptions, site constraints, utility information, vendor concepts and programme expectations to identify missing inputs and decisions that can materially change cost or execution risk.

Alternative concepts are compared on a common technical basis that can include capacity, constructability, maintainability, interfaces, schedule sensitivity and future expansion. The objective is not to produce a generic preference list, but to give the client a documented basis for selecting an option and understanding which assumptions must be confirmed before that option is committed to procurement or construction.

06

Construction-stage engineering and technical governance

Design intent is continuously tested by field conditions, vendor information and installation constraints. Construction-stage engineering provides a controlled path for RFIs, technical queries, substitutions, non-conformities and site-driven changes. Each issue is reviewed against the approved design basis and its effect on other disciplines before a resolution is released to the field.

For the client, this creates technical governance without disconnecting engineering from execution. Decisions remain attributable, cross-discipline impacts are visible and as-built information can be updated from approved records. This is particularly important on brownfield or fast-track programs where unresolved field decisions can otherwise accumulate into commissioning and handover risk.
