SWIZ Energy / Divisions / Engineering Services
Division 01 · Engineering Services

Engineering that starts at the specification, not the invoice

Our engineering teams work across electrical, mechanical, HVAC, automation and civil disciplines — from load calculations and single-line diagrams through installation, testing, commissioning and long-term maintenance support.

Process

How a engineering services enquiry moves

Same ten stages as every SWIZ ENERGY scope — the depth of each stage changes with the size of the job.

01

Requirement

You send a BOQ, drawing, part number, datasheet, photo or a plain description of the problem.

02

Technical review

An engineer reviews the requirement and comes back with clarifications, not a guess.

03

Survey & design

Where the scope needs it: site survey, load analysis, sizing, drawings and BOQ preparation.

04

Sourcing & RFQ

We issue RFQs to a matched supplier panel and pull in manufacturer documentation.

05

Comparison

You receive a technical compliance sheet alongside the commercial comparison — both, not one.

06

Order & inspection

Purchase order, manufacturing follow-up, expediting and inspection before shipment.

07

Logistics & delivery

Freight coordination, documentation and delivery to the site or consolidation point.

08

Install & commission

Installation supervision, testing, commissioning and handover with as-built documentation.

09

After-sales

Spares, maintenance contracts, O&M support and repeat-order pricing.

10

Repeat & framework

Call-off pricing, agreed stock holding and framework arrangements for recurring items.
