“Cement Concrete Compliance Adjustment”, by calculation.
Payment for “Cement Concrete Compliance Adjustment” will be calculated by
multiplying the unit Contract price for the cement concrete pavement, times the
volume for adjustment, times the percent of adjustment determined from the
calculated CPF and the Deficiency Adjustment listed in

Section 5-05.5(1)A

5-05.5(1) Pavement Thickness

Cement concrete pavement shall be constructed in accordance with the thickness
requirements in the Plans and Specifications. Tolerances allowed for Subgrade
construction and other provisions, which may affect thickness, shall not be construed to
modify such thickness requirements.

Thickness measurements in each lane shall comply with the following:

Thickness Testing of Cement Concrete Pavement

Thickness Lot Size

15 panels maximum

Thickness test location determined by

Engineer will select testing locations in

accordance with WSDOT TM 716 method B.

Sample method

AASHTO T 359

Sample preparation performed by

Contractor provides, places, and secures

disks in the presence of the Engineer

Measurement method

AASHTO T 359

Thickness measurement performed by

Contractor, in the presence of the Engineer

Reflectors shall be located at within 0.5 feet of the center of the panel. The Contractor shall

supply a sufficient number of 300 mm-diameter round reflectors meeting the requirements

of AASHTO T 359 to accomplish the required testing.

The Contractor shall provide all equipment and materials needed to perform the testing.

Thickness measurements shall be rounded to the nearest 0.01 foot.

Each thickness test location where the pavement thickness is deficient by more than
0.04 foot, shall be subject to price reduction or corrective action as shown in Table 2.

Table 2

Thickness Deficiency

0.04’ < Thickness Deficiency ≤ 0.06’

0.06’ < Thickness deficiency ≤ 0.08’

Thickness deficiency > 0.08’

Remove and replace the panels or the panels

may be accepted with no payment at the

discretion of the Engineer.

Cement Concrete Pavement

The price reduction shall be computed by multiplying the percent price reduction in
Table 2 by the unit Contract price by the volume of pavement represented by the
thickness test lot.

Additional cores may be taken by the Contractor to determine the limits of an area that
has a thickness deficiency greater than 0.04 feet. Cores shall be taken at the approximate
center of the panel. Only the panels within the limits of the deficiency area as determined
by the cores will be subject to a price reduction or corrective action. The cores shall be
taken in the presence of the Engineer and delivered to the Engineer for measurement.
All costs for the additional cores including filling the core holes with patching material
meeting the requirements of Section 9-20 will be the responsibility of the Contractor.

General Requirements for Structures

6-01.1 Description

This section relates to structural and incidental items used in any or all types of existing
or proposed Structures. These provisions supplement the detailed Specifications supplied
for any given Structure. These provisions apply only when relevant and when they do not
conflict with the Plans or Special Provisions.

6-01.2

Foundation Data

Foundation data in the Plans (from test borings, test pits, or other sources) were
obtained only to guide the Department in planning and designing the project. These
data reasonably represent the best information available to the Department concerning
conditions and materials at the test sites at the time the investigations were made.

6-01.3

Clearing the Site

The Contractor shall clear the entire site of the proposed Structure to the limits staked by
the Engineer.

6-01.4

Appearance of Structures

To achieve a more pleasing appearance, the Engineer may require the Contractor to adjust
the height and alignment of bridge railings, traffic barrier, and structural curbs.

6-01.5 Vacant
6-01.6

Load Restrictions on Bridges Under Construction

Bridges under construction shall remain closed to all traffic, including construction
equipment, until the Substructure and the Superstructure, through the bridge deck, are
complete for the entire Structure, except as provided herein. Completion includes release
of all falsework, removal of all forms, and attainment of the minimum design concrete
strength and specified age of the concrete in accordance with these Specifications.
Once the Structure is complete,

Section 1-07.7

shall govern all traffic loading, including

construction traffic (equipment).

If necessary and safe to do so, and if the Contractor requests it through a Type 2E
Working Drawing, the Engineer may allow traffic on a bridge prior to completion. The
maximum distributed load at each construction equipment support shall not exceed the
design load by more than 33 percent. The written request shall:
1. Describe the extent of the Structure completion at time of the proposed equipment

loading;
