Sample Project – Road Survey – Hardin County, OH

Filed in Road Surveys by on January 15, 2020 0 Comments • views: 88

A large wind energy generation project was in the final stages of negotiation when the county suggested that roads damaged by the installation of the towers would require replacement. The customer hired us the document the preconstruction existing conditions of the roads to be affects.

This project documented existing conditions of multiple roadways sections scheduled to be used as access roads and haul routes by heavy trucks bringing equipment and materials to a adjacent worksites.

This also required shooting documentation of county maintained farm field access roads.

8.5 minute sample from MiniDV camera fed to hard drive recording 480P.

As is our policy the client and their specific requests or requirements will not be included here. However I can present samples of projects to show you what we do and some of the variation in the type of projects, subject properties covered and types of presentation.

This includes a short sample from a vehicle mounted SD camera with typical descriptive audio and custom overlays including location, Road name and plotted path of survey section. Areas of roadway with preexisting damage can easily be identified by comparing the footage with audio description to satalite mapping imagery.

Camera hard mounted on rig over cargo van approx. 10ft over road surface.
Footage shot with vehicle maintaining approx. 10-15mph speed, shooting in progressive mode so all surface details retained and visible. Mastered as uncut AVI file (archived with original tape). Section 5 of 8 produced for project over 2 days. Editing included syncing separately recorded audio (for clarity as camera microphone was outdoors and subject to wind noise).
Overlays added and adjustments to overall exposure, contrast, etc.
Delivered on DVD as narrated uncut video documentation of subject area.

A custom roof rig for mounting a tape based SD camera with a feed into the van to a computer monitor. Driving approx. 15mph with flashing lights and hazard signs shooting progressive footage captures all tar fills, oil stains and surface conditions, and allows reasonably sharp screen captures.

We now shoot jobs with these requirements with a second 4K wide view camera, providing additional resolution as well as GPS tracking including elevations.
