Observations/Finding

At the request of the client’s representative, our AS ENGINEERING AND CONSULTING, LLC (ASEC) representative visited the job site to observe the contractor’s work activities from a quality standpoint to verify compliance with project drawings/specifications, applicable codes, and materials submittals and conducted QC testing per the project drawings and specifications.  The following observations were made during our evaluation:

Site Arrival and Initial Conditions:

Upon arrival at the site, a rain delay was in effect for 2 hours. This delay affected the initial planned activities.

Graded Aggregate Base (GAB) Placement:

• The GAB was placed until completion, ending at the Cul-de-sac.
• The future roadway was compacted using a Hamm smooth drum roller HD14 to seal the surface.
• The GAB placed was not ready for testing at this time.

Future Activities and Equipment:

• The paving company foreman stated that a large smooth drum roller would be delivered next week to provide compaction.
• Compaction testing will need to be completed once the large smooth drum roller is available.

Observations:

• The delay due to rain was managed effectively.
• The compaction process with the HD14 roller was observed, but further compaction and testing are pending.
• Coordination with the paving company is ongoing to ensure timely delivery of necessary equipment.

Recommendations:

• Monitor the delivery and usage of the large smooth drum roller.
• Schedule and conduct compaction testing as soon as the GAB is ready to ensure compliance with project specifications
