Dear Sir:
As requested, lue ret rrith 1ou and },lr. Jim l,tcDonald on rl.rbber 28,19Bl to observe tfie build.irq distress and deterrnile tlre prcbable cause.
Distress of tlre 2 front buildi:rg @rners on both structures has
bee.n operienced. Tfe distress, consisting nrainly of fou:rdatic,n walland floor srab separation frcrn the original structure, wa.s npst severeon the west corner of Building Unit 13 and both scrners of Buildingunit 15. M.inor distress qaas noted at ttre east corner of errildlng r3nit13. Ttre corners of these build"ings are fornd.ed on spread fmtingsplaced on approxjnately 10 feet of baci<fill. Ccxrpactj-on testing wasapparently not perforned on th_is rnaterial. The f,ourr:lations su6rynrtingthe crcrner additlons are dord"led into the nain buildilg for:rrdauion.
Surface drainage adjacent tte buiJ-ding and the addition area !,rasrelatiirely poor ard appea-rs to tr,ave al1cx,'ed ncistrrre to pond adjaoenttle structure. I€ r:rxlerstard ttrat the final backfi-}l to the presspggrade was just reoently placed. Drainage adjacent the east oorner ofBui-1ding Unit 13 is relatirrcIy good.
Drainage along the roadmy r:phill of the site alpears to outletonLo lot 13. Ilre draia grate located on the rphill road shoulder
was observed to be plugged with debris.
The observed hrilding distress has been catrsed by differentialfoundatlon settlsrent. The outside @rner appears t.:o have settJ.eddiffererrtialry with req)ect to the dc,h,elled section causing uplift ofthe interior srab oorner. Tl€ settlerent has probably been accreleratedby wetLing of ttre backfirl. settl-enent of this tlFe can be e4ncted forfootings placed on wetted backfill especi_a11y wtrere the backfill has
