About this file
This document contains a camera inspection report of runway crossing ducts at a military base in Belgium and the related federal contract opportunity for utility modernization at that base. The inspection report details a visual and sewer robot inspection of two awaiting ducts located underneath the runway, one of which was accessible. It describes flooded conditions, oval duct shape and dimensions, existing water and gas pipes, and obstacles preventing full inspection. The related federal contract opportunity is a Request for Proposal for utility modernization work at the base, with a pre-proposal site visit planned for a future date. Interested offerors must register to attend by submitting contact information by June 18, 2021.

Visual inspection:
On the received utility map, 2 awaiting ducts are situated underneath the runway. Only the western duct is accessible via CV40 (see figure 1). This one consists out of 2 manhole covers leading to the same shaft to access the awaiting duct. Based on the utility map, this duct should contain one PE160 water pipe. The entering shaft can be seen in figure 2 where the PE 160 water pipe can be seen. It’s entering the shaft, and immediately going to the bottom of the concrete structure. The bottom of the system is situated approximately 2.5 m below the ground surface. The underground system is flooded with 1 m of water. For the other awaiting duct, no entering shaft was found.

The awaiting duct has an oval shape. Its diameters are:
- Height: 970 mm
- Width 750 mm
It contains one ‘Grès 110’ pipe (not in use), attached zo the side of the construction.
The second pipe at the bottom of the duct is the PE 160. It’s been holding up by perpendicular metal partitions. The first one is already broken down.
In the first 10-12 m, no obstructions were found in the duct. Further visual inspection was not possible.

Sewer robot inspection:
Sewer robot inspection was not executable. This is because of:
- Crossing metal partitions at the bottom of the duct
- Pipe at the bottom of the duct
- 20 cm of sludge
