What does it cost?
Overview
In schools, there are typically two costs that will account for most of
the network infrastructure investment: network switches and network
cabling. There are many factors that will affect costs (both positively
and negatively), and we will do our best to find the best value route
for you. Adhering to the BECTA standard does not mean incurring onerous
costs. Below are some of the factors that we know will impact costs, all
of which we would take account of during a site-survey.
Network switches
Switches should be carefully specified so that they provide what you
need, but not excessive features that you don't need. We will
assess your needs (capacity, application, future-proofing, resilience,
flexibility, existing hardware), take into account the BECTA
requirements, and recommend the best value switches that will satisfy
all requirements at the minimum costs.
Age and type of building
New buildings often have cable-trays fitted in suspended ceilings,
making cable runs relatively simple. Older buildings tend to have high
ceilings and very little accommodation for cabling which often means
fitting cable trunking.
The layout of the building
If your building is compact with two or more floors, the cable
routing is likely to be more simple than if it is spread over a large area
on a single level. A connection between buildings may be more
cost-effective with line-of-sight wireless link rather than cabling.
Existing network infrastructure
If you already have a network in place, there is a good chance
that we can use some of your existing containment (cable-trays,
trunking, etc) instead of running new. If we are replacing cable (eg,
upgrading CAT5 to CAT5e), we will almost certainly be able to re-use
what you already have. CAT5e to CAT6 or fibre may require some changes
to reduce corner radii, but again, we can probably re-use much of what
you already have.
Presence of asbestos
Asbestos may require us to route cables differently, or contain
cables in trunking. We will be able to determine this by examining your
asbestos register and a site survey.
