Robots Tackle Tight Waikīkī Demolition Spaces
Demolition is officially underway at 436 Ena Road in Waikīkī, where the City and County of Honolulu is using specialized, remotely operated demolition robots to dismantle an existing vacant building and clear the path for a future affordable housing development.
The city showcased the technology on a Friday morning, drawing curious onlookers to Ena Road. Mayor Rick Blangiardi, donning a hard hat and a safety vest, took the remote control to deliver the initial swipes against the structure.
“This is a great day for the City and County of Honolulu,” Mayor Blangiardi told the gathered crowd. “This has been years in the making and I will tell you, for us, it’s very fulfilling. … I’m really excited about how we’re going to take this down because that was one of the biggest challenges we had — dealing with this density, the proximity, if you will, to the adjacent properties.”
Compact Sweden-Manufactured Machines Solve Tight Site Challenges
The remotely operated units are manufactured by Sweden-based Husqvarna. They are specifically engineered to move through confined spaces while letting operators work from a secure distance.
Kevin Auger, director of the City and County of Honolulu’s Department of Housing and Land Management, explained the logistical hurdle facing the site. Because the property lacks space for large cranes or massive dump trucks, the compact robots are designed to travel up through the building’s elevator shafts to the roof, where they will begin dismantling the structure downward. Debris will then be loaded directly back down through the elevator shaft.
“We don’t have room here for large trucks. We don’t have room here for a large crane. So that was an extraordinary solution,” Auger told the crowd.
Acquisition History and Rebuilding Plans on City-Owned Land
The city originally acquired the 33-unit property back in 2018. Funding came via federal Community Development Block Grant allocations intended to provide housing for low-income residents and people experiencing homelessness. The roughly 6,000-square-foot parcel includes both a vacant eight-story building and a detached parking structure.
Final unit counts and exact affordability tiers remain to be determined as planning and financing come together. The project will also handle community engagement, environmental reviews, and standard land use approvals. Last year, the city introduced a strategic housing plan that features collaboration with the development community as a key method for creating housing on municipal property.
“436 Ena Road presents a valuable opportunity to reinvest in city-owned land and preserve affordability in the heart of Waikīkī,” Auger said in an announcement. “Demolition is an important milestone, but our focus is on what comes next — creating a high-quality development that maximizes long-term affordability, makes efficient use of this property and delivers lasting value to the Waikīkī community.”
Demolition Timeline and Future Partner Bidding
Demolition contractor R.H.S. Lee Inc. is scheduled to start structural demolition the week of Nov. 2. Work and site clearing is expected to continue through February 2027 during standard construction hours, with safety fencing remaining active throughout the project duration.
Although the city previously selected EAH Housing as its preferred negotiating partner alongside co-developer Core Tech in July 2025, that partnership has since dissolved. Auger confirmed that the project must now be rebid, with a new request for proposals expected by the end of the year. City officials do not anticipate this administrative reset will delay the broader timeline.
Concurrently, Honolulu was wrapping up demolition activities at the former Dee Lite Bakery property in Kalihi, planned to become a transit-oriented affordable rental housing complex expected to house roughly 150 units.
