Cable category
CAT6 suits most offices today. CAT6A supports higher speeds over the full distance and resists interference better, though it is thicker, costs more and takes longer to install. Therefore, choose CAT6A where you expect high-speed equipment or a long lease.
Cable length and route
Points far from the rack use more cable and more containment. Similarly, routes through risers, across floors or around obstacles take longer. As a result, a large floor with one rack in a corner may cost more per point than a compact office.
Containment
Trunking, conduit and tray protect cable and keep the office tidy. However, they add material and labour. Exposed routes in warehouses or older buildings often need more containment than offices with suspended ceilings.
Building condition
Finished buildings with closed ceilings and occupied desks are harder to work in than empty shells. In addition, solid walls and slabs may need coring. Consequently, early planning during fit-out keeps costs lower.
Working hours
Occupied offices often need work after hours or at weekends, which raises labour costs. Some Nairobi office towers also limit when contractors may work.
Quantity
Larger projects usually have a lower cost per point, because setup, rack work and testing equipment spread across more points.
