Alpha Testing, Inc. - Laboratory Agreement Work Order No. 2- Honey Springs- Cedar Crest Trail TAPP 90162

ATTACHMENT A SCOPE OF SERVICES

It is our understanding that a new trail will be constructed alongside Corinth St, Illinois Ave, and Van Cleave Dr. in Dallas County. The trail extends approximately 5.4 miles and consists of 6" think reinforced concrete. Some intersections, driveways, and turnouts will also require concrete paving. We understand that sanitary sewers manholes wi ll be adjusted and storm drains will be installed at the proposed development. In this cost estimate, we are providing our estimate of the testing anticipated based on our understanding of the project information provided in the contract documents: civil plans dated: 7/28/2017; quantities provided.

SITE PREPARATION, FILLING, BACK FILLING (BASE BID) Based on our understanding of the information provided for this project, field density testing is required on the sub­grade and fill materials placed. It is estimated that an engineering technician could be required on site for about 80 hours to perform field depth verifications and 87 field density tests. In addition, the technician could obtain approximately 3 soil samples for laboratory proctor analysis.

UTILITIES (BASE BID) Based on our understanding of the information provided, fie ld density testing is required on the backfill material placed. We have estimated that approximately 370 linear feet of storm drains would be excavated and installed. In addition, about 13 linear feet of water lines, and an estimated 5 sanitary sewer manholes would be adjusted. We have estimated that our engineering technician could be required on site for approximately 24 hours to perform approximately 76 field density tests. In addition the technician could obtain approximately 2 soil samples for laboratory proctor analysis.

CONCRETE TESTING (BASE BID)

Based on information provided, it is our understanding concrete wil l be placed. It is estimated that an engineering technician could be required on site for an estimated 225 hours to mold approximately 358 test cyl inders and beams.

ATTACHMENT A SCOPE OF SERVICES

SITE PREPARATION, FILLING, BACK FILLING

Paving: 1 FDT each 3,000 cubic yards feet and 6 inch lift

Wall Backfill: 1 FDT each 3,000 cubic yards feet and 6 inch lift

All areas supporting slab foundations, flatwork, pavement or areas to receive new fill should be properly proof-rolled , compacted and tested.

UTILITIES

Trench Back-fill: 1 density test for every 300 linear feet each 6 inch lift.

Trench backfill for util ities should be properly placed and compacted in accordance with requirements of local City standards

CONCRETE TESTING

Paving: 1 set of 4 test cylinders every 100 cubic yards.

Utility Structures: 1 set of 4 test cylinders every 50 cubic yards.

Hardscapes or Sidewalks: 1 set of 4 test cylinders every 50 cubic yards.

Note: This cost estimate assumes sanitary sewer structures are pre-cast and will not require any testing and storm drain structures are cast- in place and will require testing. Should some of these items not require testing, this cost estimate could be revised upon request.
