CHAPTER 10.
| The inspection of the residence did find a number of problems [including]: - Numerous cracks in the foundation walls - Large cracks in the basement floor slabs - Sloping floors on various floors - Cracks in the drywall, indicative of building movement It is suspected, some of the problems are due to poor soil conditions. It is strongly recommended a soils investigation be performed to determine the soil conditions under the residence. A local geotechnical testing firm will be retained to perform this work...The results of the soils investigation and its impact on the residence's problems will be included in the report. |
| I propose to do all the work as listed in your letter in addition to the items I have added for the amount of $102,000. It is understood that the residents will have to vacate the house for approximately three months while work is under way, and all furniture will have to be removed from the areas involved. |
| The distresses within this structure [sloping floors, bowing walls, basement cracking] are not caused by any foundation related, other subsurface related, or other unusual external factors or unforeseen conditions. Identification of causes of distresses is to proceed to an analysis of (a) the design of the superstructure, and (b) the quality of the construction materials and workmanship. (It is apparent, as noted earlier, that the basement floor slab is of flawed construction. We suspect a high water to cement ratio which, combined with poor contraction and isolation jointing, is responsible for its cracking. We also suspect, as noted earlier, the possible lack of suitable granular drainage blanket.) Such superstructure and materials/workmanship analysis is to be done by the principal consultant. |
