DAILY WORK PERFORMED Field construction activities performed during this period: Saturday 09/20/14 1. The general contractor Corman Construction arrived on site to continue assembly of the truss bridge per the approved shop drawings according to Rev. 3. The contractor worked on splicing sections A103, A104 and A106. All bolts have not been installed to snug-fit position at this time as the contractor has been adjusting the grade of the bridge continuously by rigging the bridge at particular locations in order for members to align and connect. Corman continued to use a pneumatic jack and come-along to maneuver truss members into alignment. Once all sections of the bridge were connected the contractor shot grades for the bridge and attempted to get the bridge as close to grade as possible. 2. CSX Flagger Danny Meyer was on site on this date. 3. WMATA Flagger Stephon Paige was on site on this date. CONSTRUCTION MANAGER’S WEEKLY PROGRESS REPORT WEEK OF 09/20/2014 PAGE 4 of 11 Monday 09/22/14 1. The general contractor Corman Construction arrived on site to begin backfilling the Trail Abutment retaining wall. The contractor removed steel forms from the wall facing and plugged all Shea bolt holes. Corman then proceeded to install a waterproofing membrane on all construction joint per DDOT Standard Drawing 703. Corman backfilled the wall with approximately 9 inches of fill material on the inside face and then placed stone atop. Corman test pitted to find the infiltration trench drain located along the east fence of the trail work area; once located Corman started to tap into the drain and connect the 10” PVC pipe. 2. The general contractor Corman Construction had the Skidmore test done on the TCB A325 and A325 Hexagonal bolts. Skidmore test results for TCB 7/8inch diameter were 42000Ibf (2#) and 5100Ibf as against the minimum of 39000Ibf, and they were 58000Ibf (2#) and 6200Ibf as against the minimum of 39000Ibf for the A325 Hexagonal bolt. Corman did the final check on the camber and started torqueing the bolts in place. 3. CSX Flagger Danny Meyer was on site on this date. 4. WMATA Flagger Stephon Paige was on site on this date. Tuesday 09/23/14 1. The general contractor Corman Construction arrived on site to continue backfilling the trail abutment with #57 stone between approximate Station markers 47+00 and 47+50. The contract plans showed compact fill to be placed at this location but according to the approved change order the contractor submitted to place #57 stone in lieu of compact fill. Corman placed the stone in small lifts and employed compactive effort by means of a jumping jack along the edges and a remotely controlled sheep foot vibratory roller. Corman placed and compacted fill material for the 2’–0” bench shown on the outside face of the retaining wall per the approved plans. 2. The general contractor Corman Construction, second crew had the Skidmore test done on the TCB A325 and A325 Hexagonal bolts. Skidmore test results for TCB 7/8inch diameter were 39000Ibf (2#) and 51000Ibf as against the minimum of 39000Ibf for the lot number 16426 (7/8” dia.x2 ¼” TC Bolt) and 46000Ibf (2#) and 49000ibf for the lot number 17460 (7/8” dia.x2 ½” TC Bolt). The wrench check on torqued bolts was done on the splice joint bolts at 110R and 105L (topmost eight) because of the limited spaces to accommodate the calibrated torqueing wrench. Torqueing values recorded were 660,640, 700(2#), for the joint number 110R and 620(3#) and 600 for the joint number 105L compared to the reference torque value of 580 determined with the Skidmore test calibration. Corman was also on the job site installing the angle (1.5inchx2inch) support at 12inch centers for the SIP form installation. 3. CSX Flagger Danny Meyer was on site on this date. 4. WMATA Flagger Stephon Paige was on site on this date. Wednesday 09/24/14 1. The general contractor Corman Construction arrived on site to finish backfilling the trail abutment with #57 stone between approximate Station markers 47+00 and 47+50. The contractor rolled the material with a sheep foot remotely controlled compactor and a sled tamper. The structure which was standing at approximate Sta. 47+00 was demolished by Corman to allow for the surveyors to shoot the proper line and grade. The contractor accepted a delivery of CR-6 stone to place atop the 57 stone at the trail abutment approach. Corman placed 6 inches of material at the approach per the approved plans. The material was compacted with the same aforementioned equipment. DDOT Technician was on site to CONSTRUCTION MANAGER’S WEEKLY PROGRESS REPORT WEEK OF 09/20/2014 PAGE 5 of 11 conduct density test. The first compaction test failed due to a low moisture reading; Corman wet the material, re-rolled it and a passing compaction test was conducted. See DDOT’s Technician report for soil compaction dated 9/24/14. 2. The general contractor Corman Construction, second crew and the sub-contractor TNT welders were on the jobsite welding the 1.5”x2.0” angles for the SIP truss deck pan support and the 7.5”x10”-10GA angle for the curb line (0.125” weld, 1.5inch length at 12inch center to center).
