What we do
Prastigh delivers design and engineering support across the full project lifecycle, with a focus on making decisions clear, documents buildable, and designs grounded in how assets actually operate.
A brief overview of our services
Conceptual & Feasibility Studies
We support early-stage project decisions through structured technical and commercial evaluations, so you can commit capital with more confidence and fewer assumptions.
- Preliminary engineering and feasibility studies for new assets, debottlenecking, and brownfield changes.
- Concept development and alternatives analysis that compares technical risk, cost, and schedule impact.
- Site identification and evaluation considering access, utilities, geotechnical aspects, and future expansion.
- Scope definition and review to align stakeholders before detailed engineering starts.
- Risk and uncertainty analysis focused on operability, constructability, and regulatory conditions.
- Cost, weight, and schedule estimation appropriate for concept and feasibility stages.
- Hazard identification and operability (HAZID/HAZOP-style) reviews at early phase, where changes are still economical.
Engineering Services
We provide complete multidisciplinary engineering consultancy across all project phases, from front‑end engineering design to detailed deliverables for procurement and construction.
- Process engineering and simulations for sizing, balancing, and defining process conditions.
- P&ID development and process documentation aligned with project and client standards.
- Piping layout, isometrics, and stress analysis for safe routing, flexibility, and constructability.
- Instrumentation and control system design, including field instrumentation, logic, and panels.
- Electrical and civil/structural engineering design for power distribution, foundations, and supporting structures.
- Vendor drawing review and coordination to ensure purchased equipment integrates cleanly with plant design.
- Cost and schedule control during engineering, with clear priorities when changes are unavoidable.
Project Management
Prastigh offers focused project management support to maintain control over scope, cost, schedule, and quality, especially on technically complex or fast‑track assignments.
- Owner’s Engineer roles to provide independent technical oversight and protect the client’s interests.
- Coordination of engineering, procurement, and construction activities from a design perspective.
- Contractor and vendor management support on technical interfaces, documentation, and change handling.
- Planning, tracking, and reporting that make progress and constraints visible to decision‑makers.
- Documentation and information control to keep revisions, approvals, and handover packages consistent.
Product & Engineering Innovation
Our product and engineering innovation team helps clients develop, refine, and industrialise engineered products, with particular strength in oil & gas and infrastructure applications.
- Concept and detailed product design, from functional requirements to manufacturing drawings.
- Design optimisation and cost reduction without compromising safety or performance.
- Prototype support, including design iterations based on testing and field feedback.
- Production‑ready engineering deliverables, documentation, and change management for scale‑up.
