Step 01
Intake & scope
Site visit, analysis of the current situation, requirements mapped. A scope with estimate, lead time and risks follows the intake. No surprises halfway through.
Technical modifications from sketch to commissioning. Steel, piping, mechanical and electrical work in our own workshop and on site. You bring the requirement, we deliver the validated result.
Modifications rarely involve just one trade. We combine steel, piping, mechanical and E&I under one project lead. No hand-overs between parties, no grey areas in responsibility.
Steelwork, pipe supports, frames, platforms and stairs. Drawings in AutoCAD/Inventor, strength calculations to EN standards. Welders EN-ISO 9606 certified.
Process and utility piping, coolants, compressed air, steam. Including pressure tests, insulation and flange connections to the required standard.
Pumps, motors, drives, couplings. Laser alignment, vibration analysis on request. For overhauls we keep critical spares in stock.
Cabling, control panels, PLC integration, instrumentation. NEN 3140 inspections, IO mapping on your existing system (Siemens, Allen-Bradley, Schneider).
Not three subcontractors, no grey areas. One project lead guides the work from intake to hand-over. Drawing, preparation, production in our workshop, installation on site, commissioning. Everything in-house or via regular, certified partners.
Site visit, analysis of the current situation, requirements mapped. A scope with estimate, lead time and risks follows the intake. No surprises halfway through.
2D/3D drawing in AutoCAD and Inventor. Strength and stress calculations for structures. EEMUA/API/EN standards as the basis. Separate drawings for welders, mechanical fitters, E&I technicians.
Steel construction, piping, skid build, support structures. Welders certified to NEN-EN-ISO 9606. Coating/painting via a regular partner. Pre-assembly and testing before transport.
Removal of the existing installation, foundation adjustment, placement of new components, connection of process and E&I. Work permits via your system (iGP, eWP) or our own process.
Trial running, pressure tests, electrical tests, statutory checks. Together with your crew we verify that the modification does what was agreed. Reporting in line with FAT/SAT protocol.
As-built drawings, parts list, maintenance instructions, material and welding certificates. Warranty terms recorded in the quote.
No formal lower limit. Small jobs (a single trestle, a small frame) we prefer to bundle. For projects with full project management we look at what is reasonable for both sides.
Both. We can start from a note on the back of a delivery slip or from a finished engineering pack. Our own engineering team supplies workshop drawings and strength calculations to EN standards.
VCA** (petrochemical), NEN-EN 1090 for steel construction, welders certified according to EN-ISO 9606. PED 2014/68/EU for pressure equipment where applicable. Certificates included in the project file.
Often, yes, with the right method: isolation, LOTO, hot-work permits. For critical interventions we prefer to fit into planned shutdowns to minimise risk.
We set out warranty terms on workmanship and materials per project in the quote. Manufacturer warranties on components (pumps, motors, instrumentation) are passed on in line with the manufacturer's terms.
Tell us what you want to change. We listen, ask questions, and shortly afterwards bring scope, price range and a realistic lead time to the table. No letter of intent required.
Same people, same approach, different angle. Clients often combine multiple services in a single framework agreement.
