Muhtasari

Roseville Tunnel huko New Jersey ilijengwa mwanzoni mwa miaka ya 1900 na ina urefu wa futi 1,000 hivi, ikiwa na miamba wazi isiyo na kitambaa kwa asilimia 85 hivi na kitambaa cha zege kwa sehemu iliyobaki. Mradi huo unajumuisha ubunifu wa mwisho wa ukarabati na ujenzi wa kichuguu hicho na njia zake za kuingilia — ukarabati wa miundo, kibali salama cha uendeshaji wa reli, uimarishaji wa miamba wa njia za kuingilia za kichuguu, upunguzaji wa uingizaji wa maji kupitia uboreshaji wa paa na kuta za pembeni, ufungaji wa CCTV, na maandalizi ya msingi wa reli ndani ya mipaka ya mradi. Kwa kuwa mradi huo umezungukwa na ardhioevu, ubunifu ulihusisha mpango wa kina wa udhibiti wa mmomonyoko na mchanga, wenye mabwawa ya kukagua na uzio wa mchanga kuzuia utuaji wa mchanga wakati wa ujenzi.

Uongozi wa Uhandisi wa Kiraia na Trafiki

Gedeon GRC Consulting alihudumu kama mhandisi mkuu wa kiraia na trafiki mwenye jukumu la vipengele vyote vya ubunifu wa uhandisi wa kiraia/eneo na trafiki wa mradi: tathmini ya eneo; huduma za jamii; MOT/MPT; usimamizi wa maji ya dhoruba; Mpango wa Kuzuia Uchafuzi wa Maji ya Dhoruba (SWPPP); mipango ya udhibiti wa mmomonyoko na mchanga; mifereji ya maji; maelezo ya kina ya msingi wa reli ikiwa ni pamoja na muunganisho wa mpangilio wa kijiometri, sehemu za kawaida, sehemu mtambuka na vibali vya nafasi; usawazishaji wa ardhi; uundaji wa hati za mkataba; huduma za msaada wa ujenzi; uratibu wa mashirika; na utoaji wa vibali.

The area, surrounded by waterbodies, has flooded in the past during heavy rains — and one of the project’s objectives was to alleviate, if not eliminate, that flooding. Gedeon GRC performed a comprehensive watershed analysis to determine flow within the project limits and adequately size the drainage system, which consists of ditches with perforated pipes through the tunnel. Drainage calculations were prepared pursuant to the NJDEP Best Management Practices Manual for the 2-year, 10-year and 100-year events; sizing the under-drain pipes also required factoring in water percolating through the tunnel wall.

The design was performed on a fast-track schedule requiring multiple submissions and extensive coordination with all parties, with document controls managed in Bluebeam, Autodesk BIM 360 and Autodesk Construction Cloud to track and maintain deliverable schedules.

Uthibitisho kwa Kutumia Ndege Isiyo na Rubani

Bila gharama kwa mteja, Gedeon GRC anatumia Flyability Elios 3 — ndege isiyo na rubani yenye LiDAR — kuchora ramani ya ndani ya kichuguu hicho. Uchunguzi wa mara kwa mara wa eneo unaweza kukamilika kwa chini ya dakika 30 na kubadilishwa kuwa michoro ya CAD, ikimwezesha mkandarasi kuthibitisha kuwa eneo hilo linajengwa kulingana na vipimo vya ubunifu.
