City of Tukwila Allan Ekberg, Mayor INFORMATIONAL MEMORANDUM TO: City Council FROM: Rachel Bianchi, Deputy City Administrator CC: Mayor Ekberg DATE: October 16, 2018 SUBJECT: Lydig GCCM Contract Amendment for Demolition of existing structures on future Fire Station 54 site ISSUE The City purchased the property at 42nd Ave. S. between S. 139th and S. 140th earlier this year in anticipation of siting the new Fire Station 54 at this location. Since that time, the Council has chosen to defer construction of the building. The existing structures on the site — a single family home that has been long vacant and a former greenhouse — are a public nuisance and need to be demolished. The Administration proposes to amend the GCCM preconstruction services contract with Lydig Construction, the GCCM already contracted to complete the Fire Station projects, to demolish the buildings. BACKGROUND In November of 2016, the voters in Tukwila approved the City's Public Safety Bond as a part of the overall Public Safety Plan. Higher than expected construction cost escalation rate as well as extremely saturated construction market in the greater Seattle area have resulted in the construction budgets much higher than originally anticipated in the Bond measure. As a result, Fire Station 54 was removed from the program and Public Works scaled to the original budget of $30M. In November 20, 2018, the City signed a GCCM contract with Lydig for Fire Stations 51, 52 and 54, including $372,000 in preconstruction services. In July, the City authorized Amendment 1 to Lydig's contract which removed Fire Station 54 from the contract. In order to accomplish the demolition of the structures on the site, the demolition scope must be included in the contract. However, the savings in preconstruction services from not moving ahead with building the new 54 will cover the cost of demolition services, and no additional funds are needed. Council is simply being asked to modify the scope to include demolition. At the City's request, Lydig has completed a competitive bid process for the demolition of existing structures on the future Fire Station 54 site. The City seeks to amend Lydig's scope of work for preconstruction services to include demolition of these existing structures. The cost of this effort is approx. $67,998 plus Washington State sales tax, to complete the demolition of existing structures and is within the already approved preconstruction budget. RECOMMENDATION The Council is being asked to authorize the Mayor to sign Amendment 2 to Lydig's GCCM pre - construction services contract for the demolition of existing structures at the future Fire Station 54 site after the October 22, 2018 C.O.W. at the Special Meeting that same night.
