Aerial Fiber Route Design Verification and Documentation Harris, Fort Bend, Brazoria, Galveston, and Waller Counties DCCM performed an as-built field survey of the aerial fiber route to verify that it was installed according to design at the correct attachment height. We obtained and documented the heights of all telecommunications cables and electrical conductors in a database spreadsheet. We analyzed the field data for compliance with the design. We created a pass/fail analysis indicating which fiber attachments complied with the design and the National Electrical Safety Code® (NESC) clearance standards. Our team determined which fiber attachments failed and did not comply with the design and NESC clearance standards.

Denton County Fiber Audit Documentation Denton County, Texas DCCM performed a fiber audit for Denton County’s single-mode fiber network, including auditing splice enclosure configurations, fiber patch panel configurations, and fiber-optic cable routing. The project involved over 70 miles of fiber audits with field verification to document patch panel and splice enclosure configurations. Our team provided GIS Esri work to update the Denton County Crescent Link Database with the fiber audit information for the splice enclosure and patch panel configuration documentation. SERVICES PROVIDED Existing fiber network audit Documentation of splice enclosures and patch panel configurations Measurements Redlines on prints Field verification and documentation Photos and identification of splice enclosures, patch panels, and telecommunications bay/racks Created Geospatial reference in GIS using Esri tools Update Crescentlink database with fiber audit documentation At a Glance 70 miles Fiber Audit 2024 Construction Completion Markets Power Services Utilities

Addicks Substation Telecommunications Site Elevated Platform Houston, Texas DCCM performed civil/structural and telecommunications engineering and designed a telecommunications site with an elevated platform for a 10-foot by 12-foot telecommunications shelter on an elevated 22-foot by 36-foot by 12-foot-high structural steel platform. The scope of work included the engineering and design of the telecommunications site and the creation of site plans, fiber route plan and profiles, plans of the telecommunications shelter, generator, propane tank, ice bridge connection to the tower, fiber route, and electrical power conduit connections. We provided design from the telecommunications shelter to the substation control rooms, existing backbone fiber ring connections passing through the substation to insert the telecommunications site onto the network, completing telecommunications-specific power designs for generators, UPS, battery, charger, loading, grounding, breaker panel, wire and fuse sizing, all applicable calculations, etc. Our team provided the appropriate hardware in accordance with the client’s design standards. The project included complete grounding and bonding design for the ground ring, creating site plans, grounding system plans and details for the elevated platform, telecommunications shelter, equipment, and tower in compliance with CenterPoint Energy, manufacturer, and industry standards. The design of the structural steel and concrete engineering and foundation included structural engineering, design, and calculations for concrete pier foundation supports and reinforcement, structural steel fabrication drawings, isometric platform drawings, stairs, and handrails.
