F
OUNDATION
FOR

A SIX

STOREY

Bureau of Internal Revenue

Revenue Region No. 13

Cebu City


BACKGROUND



The Bureau of Internal Revenue, Revenue Region No. 13, Cebu

City is a 3
-
storey building
situated on a 7,268 sq.

m.

lot

and was inaugurated on January 1982 where the Revenue District
No. 81, Cebu City
-
North is co
-
located with the Regional Office. For 31 years, the building
survived from natural calamities such as earthquakes, typhoons including major physical
renovations.

Aside from the increased number of personnel assigned in the regional office as
well as in RDO
No.

81
-
Cebu City North the management deemed it necessary to put up a new
building rather than put annex building beside it. Adding another floor of the old b
uilding is not
advisable

due to the absence of “as built plans” of the building and DPWH cannot issue
structural stability certificate. With the old regional office building occupying only 1,155 sq.

m.,
there is still enough space to put up another big bu
ilding.



One of the many projects of the Commissioner of Internal Re
v
enue

is the construction
of a DPD Building in all Regional Offices. In line with th
is mandate
, Revenue Region No. 13,
Cebu City will construct a
One
-
Storey DPD (
Document Processing Divi
sion
)

Building
with a
Foundation for a Six
-
Storey Structure
to comply with the instruction that at least Level I should
be ready by end of 2014. With the funds in the amount of 23.5M being made available for the
construction of the said DPD Building, the
construction project will be undertaken by the
regional office.

Subsequent construction of the upper floors will depend on the availability of
funds.
