Today the contractor will be constructing a keyway for the proposed natu- ral log crib retaining system. The contractor has perform the removals to the F/L of the creek bed and has lined it with the mirlfy 140 and the perimeter boulders per plan. The 308 mini excavator began digging a keyway to the north side north of the existing 36" storm drain and wing walls with the soils being thrown onto the cut ramp where the bobcat Is being used to remove and placed in a stockpile adj. the existing barn. The soils being dug where the surrounding topsoil of 1'+-to expose the underlying the yellowish coarse grad- ed alluvial sands and water table. At this elevation of contact, the keyway was constructed with a cantering to the heel of 1. 5' +-. It was observed at the back of the first course of logs the vertical backcut to 5'+. The wall will have a slight canter to which required the contractor to start at the top of the backcut and recut an additional 3' in width so as to keep the additional crib logs on compacted fill. ***** At the toe of the keyway, per design, the toe is part of the line of large perimeter boulders mentioned. These are to aid In support of the first stretchers of logs. The contractor place crushed rock in the keyway zone that equaled 8" just behind the toe boulders to as much as 1.5' at the heel. Once leveled, the area was then cov- ered with the Mirify 140N filter fabric with the crew hoisting the first stretcher logs Into the keyway. This operation will continue tomorrow morning.

On arrival I met with the foreman Brandon with BLT const. co. and Dana, consulting design engineer and we discussed the work to be performed. Today the contractor will be constructing the log units to create the crib wall to the north side of the 36" existing SD. The logs were set In-place in a stacking fashion perpendicular to one another. The labor used an electric and gas powered drill with a 5' long l" drill bit to drill through the first two eucalyptus logs. All thread bolts were inserted with a 3" steel washer plate and two nuts to each end and tightened. No torque requirements were made, but, will be serviced and maintained for the first year after completion. Once the first course of the logs were set and bolted the contractor placed 15"+-sized boulders up against the back side of the face of the logs. These oversized rock are to prevent the finer material from being eroded from the cell create by the fastening of the logs. Once the o.s. rock were in-place. The excavator was used to mix the native soils with some 6"-rock to an unknown percentage and was placed Into the cell from the back of the o.s. rocks to the front side of the rear log. This material was then leveled and hit slightly with the hand whacker. The excavator then used the stockpiled soils from the initial dig to place behind the wall up against the back- cut and the mlrify 140N filter fabric. Testing conducted showed the minimum requirements set by the plans. Today a meeting of all parties involved in making this project possible took place with Q&A on various proce- dures with the success In building the wall. Jeff Kent was among the percipients.

The hand whacker was used to provide light compac- tlon so to allow the rooting system of chosen plant to take. The excavator used the stockpiled soils behind the wall up against the backcut that is separated by the mirify 140N filter fabric and fill. These soils were placed in 6-8" lifts and compacted by the hand whacker. These lifts were placed above the 4th course in the slope zone that will D/L out at the top of the backcut as a short top fill. Testing of the fill was conducted "less the upper 1' due to rooting Issues" to show the minimum requirements ***** per plan of a ?.90%RC above optimum. The contractor decided to begin the excavation for the Rip Rap rock zone Adj. the headwall spillway and start the 1:1 backcut for the northwest crib wall Adj. the headwall spillway. The Rip Rap will not be available until tomorrow. Due to this rock not on site today, the contractor informed me that only Rip Rap placement would be performed tomorrow with the keyway excavation performed on Monday.

On site this day to continue the observation and testing of the wall backfill of the natural log retaining wall. On arrival I met with the foreman Brandon with BLT canst. co. and we discussed the results of the storm damage. The contractor had placed the BMT's on Friday into Saturday with little damage done to the improvement to date . . The work today will include the removal of the remaining backcut for the north wall and keyway zone. At early morning hours the 308 excavator through a track and causing delays to the focused work. Once the track was repaired the excavator removed a large root ball from a previously fallen tree. Once re- moved the backcut was cleaned up when the city PM and inspector showed and inspected the work to date. They suggested additional rip rap be placed at the southerly side of the southerly wall where during the last rain fall over the weekend washed out fines to the lower section outside the crib wall Into the natural ground. Once these rocks were placed, the excavator began digging the very north portion of keyway. The material exposed was the underlying old alluvium that was an SC-wet modeled grayish green in color with very slight porosity present. The keyway was founded Into this material with the remaining keyway length extended to the south up to the designed rip rap that runs parallel with the existing 36" storm Drain. The keyway was cut to equal 6' In width with a 1' tilt to the heel applied. The contractor then place 1'+-of the 6" crushed rock in the bottom of the keyway and will have a section of 140N filter fabric placed over the rock. This operation continued to end the day at 1530hrs. and will continue tomorrow morning.

On site this day to continue the observation and testing of the wall backfill of the natural log retaining wall. On arrival I met with the foreman Brandon and today will be the continuation from yesterday's stoppage. The contractor placed three stretcher logs running perpendicular to the keyway with two cross logs. One log was placed at the front with the second placed at the rear. These logs were then bolted together creating two different cells. These cells were then lined with boulders from 1' to 2' in diameter to the inside front. Once these boulders were in place, I observed the excavator place a mixture of the 6" crushed rock and na- tive soil into the cells. The native soils without the rock were then placed at the very back of the wall behind the logs and in front of the 140N lined backcut. The hand whacker was then used to apply compaction effort to the 8" lifts to the rear of the logs to achieve the minimum requirements of a ~90% RC at above optimum. The moisture levels are approaching the maxi- mum above optimum to maintain the 90%RC. I spoke to the foreman and he is aware. The hand whacker was also used within the cells themselves to moderately compact the soils to the 85%RC. No testing was conducted within the cells. Due to the forecasted rain for Sunday the 27th the contractor spend the remaining part of the day placing plastic over the work area. This operation continued to end the day at lS00hrs.

On arrival I met with the foreman and the compaction effort will continue on the 3rd course of logs behind the back of the crib cells. ***** The hand whacker continued compaction effort making several passes over the 8" lifts. It was observed that the backfill soils that were being supplied from the stockpile had become again wet. I spoke with the foreman about my observations and he elected to use this material in the 90%RC zone behind the wall. When compact- ing with the hand whacker left ruts in the grade and pumping was observed. Moisture and density testing revealed <the minimum 90% requirement at 5.5% above optimum moisture. The foreman elected to perform the removals of the wet soils and mix in dry soils in attempt of drying back the failing zone and re-compact. This method chosen was performed with the use of the bobcat and retested to show the minimum requirements of the ;::90% RC at near optimum. Additional logs were placed to create the 41n course of the crib wall with additional backfill soils placed and compacted. Again the material was wet with additional testing showing the same results as this morning. The contractor performed the same repair method with re-testing passing. The contractor then placed rock to 2' at the front of the cells behind the expander logs. The labor used a shovel to spread 8" lifts evenly throughout the inside cell area and moderately provided compaction to the 85% ***** zone. Due to variances in the cell area of soil and rock, no testing was conducted.

Plan File No.: ProJect Street Address: CARLSBAD, CA. 92010 Contractor: BLT CONSTRUCTION CO./ HABITAT WEST Approved Documents: CODE DESCRIPTIONS OF WORK PERFORMED, SAMPLES TAKEN, WORK REJECTED, JOB PROBLEMS, PROGRESS, REMARKS, ETC. On site this day to continue the observation and testing of the wall backfill on the natural log retaining crib wall. On arrival I met with the foreman and the compaction effort will be concentrated on the rebuilding of the slope zone above the crib wall. The wall portion of backfill is complete with the filling above for the daylight fill. Roughly 5' of slope zone needs filling with the backhoe feeding 6-8" lifts to the 4-6ton dual steel drum roller. Oversized rock to 8" and deleterious material is being removed from each lift with the drum roller making several passes in compaction effort. Moisture and density testing was conducted on the backfill soils to show one failure which was reworked to the minimum relative compaction of a > 90% at above optimum. ***** This operation continued throughout the day to end the construction of the two contracted walls. This will also end the services of N&M in providing soil inspection. I notified N&M dispatch, P.M. and the city of Carlsbad. Weather: Attachments: P/C Mild STAFF START STOP REG.
