Also enclosed is Fig. 1, which shows a north and west'side view of the, foundation and the, approximate penetration depth for each of the 2 -inch diameter steel pipe underpinning piles. Fig: 2 shows the pile depths, with the approximate boring log data, as reported by Mr. Larry Johnson, Driller. Table 1, attached, shows the results of pile load tests we performed. Ten piles were load tested to two times the design load (i.e., 8,000 lbs.). The Table shows that piles B; M and Q did not have the design factor of safety of 2.0. Additional piles were driven at 8', M' and L/ to provide additional load carrying capacity. In dddition, piles M and Q were re -driven and then retested to establish new Ultimate load capacity. The Table shows that the average factor of safety for the nine piles (not including B) tested is about 1.85. This is less than the 2.0 factor .of safety specified in our letter of February 16th. Nevertheless, in our opinion, we believe this factor of safety is satisfactory since the foundation wall loading Used for establishing the pile spacing is believed to have been conservatively esti- mated. In our opinion; to the extent of the observations made during our visits to the site during Ehe coarse of the work, we believe that this project was properly constructed. We recommend that you continue to monitor the wall cracks on a monthly basis for at least the next twelve months to estab- lish if movements cease. Frederick C. eauhol, P.E.

He has also given us a drill hole log and soil samples from a boring he made near your house. :our interpretation of this log is shown on Fig. 1 and'grain•size curves of the typical soils are shown in Fig. 2, attached to this letter. We have evaluated thepeinetratibn'data and the soils that Mr. Johnson submitted. Without.knowing the historical • aspects of the site preparation and house construction, we have had to make some assumptions regarding the cause of the problem. However, it appears that your house was bUilt on loose soils that have gradually consolidated. from the overlying weight of the house and also from seasonal pre- cipitation and/or yard water seeping through the soils. 'Naturally occurring sandy soils normally are more densely consolidated than the penetration tests indicate and it is likely your house was built upon a dumped or poorly con- structed fill. Densifying fills after they are placed is difficult and expensive. Properly constructed structural fills must be built up layer by layer, with each -layer being systematical- ly compacted at a specified moisture content. Short of removing the house and fill and starting from scratch, there are a few options open to yoti to prevent further settlement. These options consist of: 1) Pipe pile underpinning, 2) Augercast piles, Frederick C. sauhol, P.E. Manlger Byron Wittl February 16, 1987 Page 2 3) Hand excavated piers, or 4) Consolidation grouting. "-0821-01 All of these can be effective if properly installed, but soil conditions and cost factors generally determine the best method for the individual situation. A building contractor could help you in determining the best and least expensive method. The options suggested above are discussed in the following paragraphs: 1. We have had experience in arresting settlements of small buildings constructed over loose soils by using underpin- ning. Where the depth to dense soil is shallow, it may be possible to use augered or hand -excavated pits beneath the existing footing foundations., If the thickness of the loose soils is thick, it may be,necessary to use small diameter pipe piles. This technique involves excavating the soil along the sides of the footings and then driving 2 -inch diameter extra heavy steel pipe alongside the footing using a pneumatic jack hammer. ;.The piles are driven to substan- tial bearing and then jacked laterally under the footing. The'tops of the piles are fitted with a screw jack so that the load can be transferred from the • footing to the piles and thereby enable raisingor.ieveling the building. The attached .Fig. 3 describes the concept and specifications that are generally recommended. We have successfully used pipe•piles on numerous projects to underpin houses, small buildings, and concrete slabs. The work requires coordina- tion with a structural engineer to work out the pile spacing and underpinning details. The cost of installing pipe pile underpinning is variable and depends upon the length of the pile and the ease of access to the foundation to be underpinned. Depending on the footing loads, the house may require twenty to thirty piles. Drilled piers, or hand -excavated piers may be less expensive if the depth to the competent soil is shallow. 2. Augercast piles (drilled pier supports) involve boring 4 to 6 in. diameter holes down to firm soils beneath the footings, and filling the hales with concrete. The spacing of the piers would also need to be determined according to the bearing loads imposed by the house. 3. Hand -excavated piers involve digging out beneath the footing, one section at time, enlarging the footing bearing area, and pouring a new concrete footing and pier beneath 0 Byron Wittl February 16, 1987 Page 3 E-0821-01 the existing footing. Typical bearing loads for a one- story, wood frame structure are on the order of 2 to 3 kips per lineal ft. on wall loaded footings and 50 to 70 kips on column footings. 4. Consolidation grouting to densify soils involves pumping thick cement grout under pressure into the soil beneath the footing. The pressure of the cement "bulb" against the soils causes them to densify and increase their footing bearing capacity. The determination of the best method to support the existing footings and slabs requires more boring information than is available from the one boring. If you decide to go ahead with the stabilization of your house, you will need to know the depth to firm soils beneath your whole house. We recommend that more borings be drilled around the perimeter of the house to provide this additional information. - If we can be of further assistance to you on this project, or if you have questions, please contact me.
