1003.1 1003.4

1003.1DESCRIPTION —This work is the drilling of holes for dowels and the grouting of the dowels in place.

1003.2MATERIAL —

• Nonshrink Grout . Section 1001.2(e)

1003. 3 CONSTRUCTION —Drill holes for dowels at the locations and to the diameter and depth as indicated. Grout the dowels in place, using nonshrink grout to form a complete bond between the dowels and the concrete. Repair structure damage caused by dowel operations.

1003.4MEASUREMENT AND PAYMENT —Each

1005. 1 1005. 2 1005. 1 DESCRIPTION —This work is the furnishing and driving of new, unused test piles and production piles. The following definitions apply: (

a.Test Pile. A pile driven to verify the capability of the pile hammer, determine driving characteristics,

and establis h the predetermined pil e tip elevation, befor e drivi ng production piles. Test piles may als o be used to per form pile l oad tests.

(b)Static Pile Load Test. A test to determine pile bearing capacity and integrity by the application of a

static load.

(c)Dynamic Pile Load Test. A test to determine pile bearing capacity and integrity by the application

of a dynamic load and measuring the force and velocity response with a high strain dynamic load testing system. A dynamic pile load test may include post -driving analysis .

(d)High Strain Dynamic Load Testing System . A portable computer used to determine pile bearing

capacity and integrity through instrumentation of the pile with accelerometers and strain gauges during dynamic pile load t esting. (e)P roduction Pile. A pile installed to provide structural support as part of the permanent foundation. (

f.Point Bearing Pile. A pile that develops bearing capacity primarily by point -bearing on sound, well -

defined bedrock. (

g.End Bearing Pile. A pile that develops bearing capacity primarily by embedment of the lower portion

in a dense or hard bearing stratum such as soft or decomposed bedrock, or hard or dense soil . (

h.Friction Pile. A pile that develops bearing capacity primarily from soil resistance acting along the

pile shaft . (

i.Penetration. The length of pile driven into a soil or rock stratum.

(

j.Driving Resistance. The resistance of soil or rock strata to pile driving, measured in blows per length

of penetration. (

k.Estimated Pile Tip Elevation. The estimated elevation of the pile tip as indicated.

(

l.Predetermined Pile Tip Elevation. The pile tip elevation determined by the Structure Control

Engineer or District Geotechnical Engineer from the test pile(s) . The predetermined pile tip elevation locates the intended bearing strata for point bearing or end bearing piles or establishes the length of friction piles. Predetermined pile tip elevations are used to verify or adjust the estimated pile tip elevations indicated. ( m)Maxim
