THE KING CO., INC. was selected by Zahn Builders to design-build a vibration free earth retention/foundation system to support a new private residence located along Lake Michigan in Grand Haven. The earth retention system consisted of an innovative semi-tangential auger cast wall that also served as foundation support piling for a portion of the house situated over the dune slope face. Auger cast piling were also installed to support other portions of the residence. All construction took place in limited access areas, included low overhead areas to preserve surrounding trees. All installation support members were designed according to MDEQ permit conditions.
THE KING CO. INC., installed over 525 linear feet of temporary left-in-place earth retention consisting of vibration free soldier pile wood lagging. The system was designed/built for excavation depths over 22-feet from existing grade. This sensitive project, located in downtown Grand Rapids, involved installing temporary earth retention to allow the removal and replacement of an existing stone retaining wall along the Fulton St. Cemetery. 82 grouted tiebacks were installed as part of the earth retention system.
THE KING CO., INC. was selected by The Christman Company to provide design-build earth retention services. The Scope of Work involved the retention of the adjacent revenue control builidng during airport expansion construction. Over 200 linear feet of vibration-free soldier pile wood lagging wall was installed to protection the structure and nearby roadway. The depth of excavation exceeded 16-feet and involved the protection of adjacent utility lines.
THE KING CO., INC. was selected by Velting Contractors, the sitework contractor, to design and build an earth retention system consisting of a vibration free soldier pile wood lagging wall to allow the expansion of St. Mary's Hospital. Approximately 200 linear feet of temporary earth retention was installed in downtown Grand Rapids along an active roadway and numerous utilities. The earth retention system was designed for excavation depths up to 19-feet from roadway grade.
THE KING CO., INC. was selected by MPI Research and MAVCON to provide design-build services for the installation of temporary earth retention for the K2 and M2 expansion projects. Both projects involved the design and selection of appropriate earth retention to support the adjacent buildings and numerous underground utilities. On the first project, vibration free soldier pile wood lagging was installed up to depths of 22-feet. The earth retention system was tied-back with earth anchors. On the second project, a tangential auger cast-in-place wall was installed in low headroom conditions to support interior foundation columns. The wall was designed for an excavation depth to 14-feet.
THE KING CO., INC. was selected by McGraw Construction to design-build an earth retention system to protect the adjacent CSX railroad during excavation. The temporary earth retention system consisted of an internally braced steel sheet pile system designed to meet CSX railroad design criteria. The sheet pile system was installed along the CSX railroad easement. After installation, the maximum deflection measured along the earth retention was 0.25-inches, exceeding the design specification criteria - and providing a safely supported excavation for the concrete foundation installation.
THE KING CO., INC. was contracted to provide design-build earth retention services for the recent Gentex expansion project. The earth retention system was installed during off-production hours in the evenings and weekends so the installation impact would not effect the sensitive equipment and machinery in the production areas.
