V. FUTURE GEOTECHNICAL STUDIES 



The preceding discussions in this report have provided general 

 geotechnical considerations and preliminary recommendations 

 relative to the Tudor Wharf Development, Future studies will 

 be required to collect additional subsurface information, and 

 to develop definitive design criteria, construction techniques 

 and final recommendations concurrent with the structural and 

 architectural design. 



Future subsurface explorations will be required at building 

 locations or other structure locations to provide the necessary 

 data for design studies. Additional subsurface information is 

 particularly needed in the eastern portion of the site in the 

 area currently occupied by the Constitution Marina parking lot 

 which was inaccessible during the preliminary explorations. In 

 addition, data is required to provide information to 

 prospective contractors for their interpretation and evaluation 

 as they prepare cost estimates. Future explorations should 

 include test borings, test pits, and completion of in-situ and 

 laboratory testing. Test pits will be required to determine 

 the current location, geometry, and bearing level of the 

 existing granite block seawalls and other shore protection 

 elements. Such information regarding the seawall will aid in 

 determining seawall stability and reconstruction. 



The geotechnical design studies to be conducted in the future 

 are necessary to assess the following major geotechnical issues: 



o Foundation pile lengths; 



o Design criteria for foundations and excavation support 

 systems for the below grade garage; 



o Design of permanent hydrostatic pressure relief systems 

 for below grade garage; 



o Stability of existing and proposed shore protection 

 elements ; 



o Construction considerations related to the site work and 

 foundation construction; 



o Long and short term settlement of the miscellaneous fill 

 and organic soil, utility support requirements; 



o Temporary and permanent design soil and water loads; and
