Although there were several challenges in utilizing a mini-HDD rig to simultaneously pullback the two conduits, as well as to properly interface with the total of six
handholes, the installations were successfully and efficiently accomplished.
A flush mounted belowground utility box--or "handhole"--is an essential element in the BDN concept.
Figure 2 illustrates a typical handhole design as presently envisioned for the BDN.
The design features also allow the possibility of inserting an additional handhole, at any time in the future, at an intermediate point along the route with minimal disruption and construction, including at locations where it may be decide to cost-effectively omit a handhole during the initial construction stage.
Knockout ports or slots are provided at the side of the handhole to facilitate future routing of cables to the various adjacent equipment or hardware terminals (existing or replaced), as required.
Its ongoing contracts include supplying telecommunications manholes and
handholes to Saudi Telecom, Mobily and Zain.
