Construction Management Services for the widening of Honoapi’ilani Highway from Lahainaluna Road to Aholo Street: from a two lane, undivided roadway to a four lane highway with raised median landscaping. Additional improvements included 6,700 linear feet of retaining wall, topped with 4,450 linear feet being topped with a pre-cast sound barrier wall, a new 5-foot wide sidewalk along one side of the roadway, ADA upgrades at all intersections, drainage improvements including eighteen 50-foot deep drywells, new traffic signals at two intersections and new guardrails and chain link fences were installed as a means of protecting motorists and homeowners along the travel way.
The construction of the retaining wall directly adjacent to neighboring properties required extensive coordination with property owners to ensure minimal impact and disruption during the construction process. During excavation of the wall footings, monkey pod trees that were scheduled to remain in place were found to have roots in conflict with the construction. B+K worked closely with the project arborist and structural designer to redesign the footings to accommodate the root system, allowing the 100-year-old trees to remain in place as had been committed to in the project environmental statement.
