Our role

An internal tool Youssef built as part of his business development role at MCL Design, a Paris construction company. It is deployed for the company’s own use; it is not a client commission.

Context

AXION answers an internal need: bring site tracking, teams, quotes and tender responses into a single tool.

Scope

  • Projects, teams and site scheduling
  • Files, reports and client sharing
  • Quotes and conversion of bills of quantities to Excel
  • Tender module: import of the tender file and assisted drafting of the technical proposal
  • Persistent file storage

Key decisions

  1. 1Match each line of an imported bill of quantities with items already priced, to prefill missing prices.
  2. 2Restore the service in successive phases: reliable start up, security, then persistent storage.
