A ten-county region in north central Missouri has spent the past 21-years planning for construction of a lake that will provide drinking water to over 50,000 customers. Over $118 million of funding has been secured for the future lake. RK Excavation assisted a local 8(a) contractor with roadbed construction this past construction season. The construction team divided the 4-mile corridor into seven excavation sections that balanced. Articulated trucks pulling 32-CY pans moved material efficiently across the corridor. Undercutting of soft areas was required across three low areas near the location of future bridges. Once the embankments are constructed, they will be armored with 60,000 tons of Rip Rap under this same contract. Future contracts will tie the new roadbed into existing state highways ahead of the proposed dam construction.

R&K Excavation was contracted​ to Reconstruct Roads, make Signage improvements and construct a gate repair at Fort Scott National Cemetery, Kansas.

The crews at R&K Excavation are participating in the Marion Cemetery Gravesite Expansion as the site’s excavation contractor and crypt installer.  The cemetery dates to the Civil War and has areas of historic significance.  The excavation plan had to be modified to save several historical trees.  The 5-acre footprint first had to have sanitary and storm sewer pipes relocated and new pipes installed.  Next, the site was excavated and the underdrain system was installed and connected to the newly constructed storm sewer. Crypt delivery was coordinated to coincide with placement production.  String lines and laser graded equipment were used to align the crypts into sections. Crypts were set on the open graded stone and underdrain system and backfilled with pea gravel, clay and topsoil. R&K Excavation also excavated for the columbarium subcontractor, placed the foundation drain, and backfilled after construction.

The crews at RK Excavation are working to complete a relief well collection piping rehabilitation project for the Tulsa District. The Copan Dam project includes digging up all the existing collection piping, installing two weir measuring manholes, 5,650’ of 12” solid wall collection piping and 5,650’ of 12” perforated pipe. Twenty-six new 5’ X 10’ manholes will also be installed and then 37 existing relief wells will be connected to the new collection piping. The relief well water flow will be collected in the solid wall pipes and the shallow groundwater will be collected in the perforated pipe. The final part of the project involves regarding over one mile of drainage swale and rebuilding the dam’s service road.
