Geotechnical Engineering Study 00-2267 T, hree Story Addition - 500 Laurel Street, Everett January 31, 200 � Paga 2 to be addressed, it should be done by a suitably qualified exper+ under a separaie contract. Project Descri�tion We understand from ourdiscussions with you and the limited information provided � us that the current "conceptual" plan is to construct a three story addition to the westem side of the existing single-family residence. The structure will probably I comprise wood-frame construction with a concrete slab-on-grade floor at the lower level. The addition is expected to be approximately fouReen (14) feet deep [in a roughly east to west direction out from the existing structure.] Although no spe :ific design plans or structural loads are currently available for these proposed residences, basPd on our experience with similar multi-story single family residential construction, we estimate that the maximum combined building dead a�d live loads should not be expected to exceed the following: Perimeter footings Interior column loads Floor loads = 2 to 3 kips per Linzar foot = 75 kips = 120 psf ' Based on the concep;ual design plan, and taking the sites' existing topography into � account, it appears that only a minimal amount of earthwork should be anticipated on tl��s project. We estimate that excavation work might extend to a maximum depth of between about eighteen (18) inches and two feet for conventional spread � footing installation. We also estimate that a small portion of the existing sloping yard area at the northwestem comer of the proposed addition will need to be excavated, and that the excavation could be between abeut three and six feet I deep. It appears unlikely that any significant backfilling will be required on this project.
