Summary of 12 pile design and construction steps

Design steps
1	Develop bridge situation plana
2	Develop soil package, including soil borings and foundation recommendationsa
3	Determine pile arrangement, pile loads and other design requirementsa
4	Estimate the nominal geotechnical resistance per foot of pile embedmentb
5	Select resistance factor(s) to estimate pile length based on the soil profile and construction controlb
6	Calculate the required nominal pile resistance R _n b
7	Estimate contract pile length L b
8	Estimate target nominal pile driving resistance R _ndr-T b
9	Prepare Cadd notes for bridge plans
10	Check the design depending on bridge project and office practice
Construction steps
11	Prepare bearing graph
12	Observe construction, record driven resistance and resolve any construction issues

Construction steps
11	Prepare bearing graph
12	Observe construction, record driven resistance and resolve any construction issues

These steps determine the basic information for geotechnical pile design and vary depending on bridge project and office practice

These steps are modified for piles that are end bearing in bedrock (refer to Green et al. (2012) for more details)
