First-time-approved LLD packs for a 20-year 5G backhaul concession.
Challenge.
Boldyn Networks (formerly BAI Communications) needed the full-lifecycle design for a DWDM optical bearer and high-count fibre feeding 5G small cells on TfL street furniture under the 20-year Connected London concession, with the Streetscape workstream sharing re-used TfL ducts, fibre and street assets. Every span had to close within a 12 km reach budget, and the Streetscape design rules had to hold at scale.
Approach.
As Senior Fibre Design Engineer, we ran survey to IHLD, HLD, LLD and as-built: Base Station Hotel fed cluster architecture, DWDM channel plans, splice and closure schematics, chamber and gel-wrap layouts, and laterals to lighting columns, CCTV columns and bus shelters. We streamlined the QGIS and IQGeo workflow and developed the IQGeo platform against Streetscape design rules, embedding automation and data QA in production.
Outcome.
LLD packs covering link-loss budgets, fibre allocation, splice packs, BoM and civils SLDs, approved first time by the client.
Bring us in at survey, not at rework.
A 30-minute technical call to pressure-test route, reach and margins before anything is committed to civils.
