SUM ENGINEERS

Some engineers.
Every discipline.

From lines of code to lines on a site plan, we engineer the things people rely on.

01 — About

Two worlds,
one team.

SUM ENGINEERS is the building arm of SUM. We design and build across two worlds that are usually kept apart: the digital world of software, data and connected devices, and the physical world of buildings, structures and infrastructure.

Most real projects need both. By keeping these disciplines under one roof, we can plan a project as a whole instead of handing it between separate contractors who never talk to each other.

Read it out loud: SUM ENGINEERS is "some engineers". A team of specialists who each bring a different discipline to the same problem.

What we engineer.

Σ D 06 services

Digital engineering

Software, data and connected devices.

  1. D-01

    Software development

    Custom business software, internal tools and automation built around the way your organisation actually works.

  2. D-02

    Web and mobile applications

    Websites, web apps and mobile apps for Android and iOS, from first prototype to launch and ongoing support.

  3. D-03

    Cloud and infrastructure

    Hosting, servers, backups, deployment pipelines and the monitoring that keeps systems running.

  4. D-04

    Data and AI

    Databases, dashboards, reporting and practical machine-learning features that turn existing data into decisions.

03 — Combined

Where the two
worlds meet.

Most real projects need both. Here is how the parts add up.

  1. B-02 Construction+ B-04 Electrical engineering+ D-06 Networking and security

    A working office

    A sound structure and reliable power, with the network, access control and software its people use every day.

  2. B-05 Mechanical and plumbing systems+ D-05 IoT and embedded systems+ D-04 Data and AI

    A factory that reports

    Machinery installed safely, with sensors and dashboards that show how it is running.

  3. B-04 Electrical engineering+ D-05 IoT and embedded systems+ D-02 Web and mobile applications

    A home that manages itself

    Solar, wiring and lighting, with connected controls you can check from your phone.

04 — Process

From first survey
to long-term support.

  1. 01

    Understand

    We start with the problem, the site and the people involved before proposing any solution.

  2. 02

    Design

    Drawings, specifications, prototypes and estimates you can review before work begins.

  3. 03

    Build

    Delivery in clear stages, with regular progress updates and quality checks at each step.

  4. 04

    Support

    Handover, documentation and maintenance so what we build keeps working after launch.

05 — Clients

Who we build for.

C-01 Σ

Homeowners
