Custom EPC software

Design automation, validated calculators and a data hub.

Every EPC firm has spreadsheets that should be software and design steps that should be automated. We build plugins and scripts for your design tools, validated calculators that replace spreadsheets, and an engineering data hub that joins tags, equipment, documents and materials across tools.

// what matters here

What is different in this industry.

01

Design automation

Plugins and scripts for Hexagon Smart 3D, AVEVA, AutoCAD and Revit that run rule checks and generate routine deliverables, built on each tool's API.

02

Validated calculators

Engineering calculations moved out of spreadsheets into software with versioned inputs, an audit trail, and checker and approver sign-off.

03

An engineering data hub

Tags, equipment, documents and materials joined across tools, with digital handover to the owner scoped to a CFIHOS-style standard.

04

Your tools stay

We build around the platforms you license and integrate through their APIs; you supply the access and the licences.

// example projects

Priced examples for this service.

Each one is hypothetical, labelled as such, and priced live from our rate card. Open any of them in the estimator and make it yours.

Example projectWeb app

Earned-value dashboard with P6

Hypothetical. Not a client, not a result.

// The problem

Installed quantities come from the field, the schedule from Primavera P6 and costs from the ERP, so earned value is rebuilt by hand every week.

// What we would build

A progress platform that takes installed quantities from field tools, applies your rules of credit, reads the P6 schedule and ERP costs through their APIs, and shows earned value and progress against the schedule by area, discipline and contractor.

// What is in it

  • Installed quantities captured in the field or imported from contractors
  • Rules of credit by commodity, set by your project controls team
  • Primavera P6 activities and baselines read through its API
  • Costs and commitments from SAP or Oracle
  • Earned value, progress and forecasts by area, discipline and contractor
  • Reports your project controls team can schedule and share

// Stack

  • Next.js
  • PostgreSQL
  • Primavera P6 API
  • SAP or Oracle APIs
  • Azure

Vendor portal with Aconex

Hypothetical. Not a client, not a result.

// The problem

Hundreds of vendors submit drawings and datasheets for review, and the review cycles, comments and overdue items are tracked in spreadsheets beside Aconex.

// What we would build

A vendor data portal that sets each purchase order's required documents, tracks every review cycle and return code, chases what is overdue and exchanges transmittals with Aconex through its API, with dashboards by package and by vendor.

// What is in it

  • A vendor document register generated from each PO's requirements
  • Review cycles with return codes, comments and due dates
  • Transmittals in and out of Aconex through its API
  • Overdue and at-risk documents by package, vendor and discipline
  • Turnover and handover packages assembled from the approved set
  • Single sign-on through your Entra ID

  • PostgreSQL
  • Aconex API

// questions

Questions we get about this.

Do you replace our engineering tools?

No. We build around them: plugins, scripts and integrations through their APIs, and software for the jobs they do not cover.

How are calculators validated?

Each calculator is tested against worked examples your engineers provide, every input version is kept, and results carry the checker's and approver's sign-off.

Can the data hub produce the owner's handover data?

Yes, in the structure the owner specifies. We scope CFIHOS-style handover with you and the owner's data team.
