SECTION 3.0
MEASUREMENT FOR PAYMENT
3.01
GENERAL
This section defines how pay items, enumerated in Attachment G - Price and Payment
Provisions are measured for payment. The estimated quantities detailed within Attachment
G are for Bid evaluation purposes. Only satisfactorily completed Work will be eligible for
invoicing.
A.
Work Measured
Work shall be measured net as fixed in position and each measurement shall be
taken to the nearest 0.1 meter. This principle shall not apply to dimensions stated in
descriptions.
Unless otherwise stated, no deduction shall be made from items required to be
measured by area for areas of less than 1.00 m2. Deductions shall refer only to areas
within the edges of measured areas; areas, which are at the edges of measured areas,
shall always be deducted irrespective of size.
3.02
METHOD OF MEASUREMENT
This subsection defines the method of measurement of particular items of Work.
A.
B.
Excavation to lower grade levels shall be the net volume of earth before excavation
to lower the grade level of the existing Site to:

The finished grades (adjusted for the required thickness of stone mulch, marl,
S1eet sand fill) in unpaved areas.

Formation levels under proposed roads and pavings.

The bed levels of shrubs and ground cover planting adjusted to the required
thickness of planting soil excluding tree-planting pits in the proposed planting
areas.

The excavation shall be net volume regardless of the method adopted by the
Contractor to execute the Work.
Imported filling material shall be the net volume of imported material less
excavated material used for fill required to fill the Site from existing levels to:
F-1-28
Contract No. 08C-C12

The finished grades (adjusted for the required thickness of stone mulch, marl,
S1eet sand fill) in unpaved areas.

Formation levels under proposed roads and paving.

The bed levels of shrubs and ground cover planting adjusted to the required
thickness of planting soil excluding tree-planting pits in the proposed planting
areas.

The imported filling material shall be net volume regardless of the method
adopted by Contractor to execute the Work.
C.
The measurement for cutting roads shall be measured along the centerline of the
excavation and includes the lengths of road and sidewalk crossed.
D.
The measurement of asphalt surface course, asphalt base course, road base and subbase shall be the area required to fill the excavation as per the required thickness of
each course.
E.
The measurement for curbs shall be along the inside face of the curb.
F.
Measurement for curb marking shall be the length measured along the marked
section of curb.
G.
The measurement of drains, sewers, pipework, ducts and duct bank shall be taken in
the horizontal plane between outer faces of structure and other items, which are
subject to separate measurement.
H.
The measurement of cables or conductors in ducts or direct buried in trench shall be
the straight line horizontal distance between center to center of manholes or main
equipment center or along the trench center line. When changes of direction occur
between points of measurement, coordinates of intermediate points of intersection
shall be used. No adjustment will be made for splices, terminations, tap and offsets
in manhole and chambers for cable staking.
I.
The measurement of pavement markings shall be taken in the horizontal plane
between outer edges.
J.
The measurement of material for asphalt and aggregate courses shall be net volume
regardless of the method adopted by Contractor to execute the Work.
K.
The measurement of planting soil shall be the actual volume to be filled; no
deduction shall be made for the root-ball.
