Contractors presented updated schematic-design cost estimates and a timeline for the Law Enforcement Center (LEC) expansion at the Cook County Board meeting on March 25.
Dean Johnson of Johnson Wolseley Constructors told commissioners the team verified market pricing at the schematic design level and separated costs between the new addition and existing-building upgrades. He reported a schematic-design estimate of $6,010,948 for the new addition and $1,984,241 for work in the existing building, and said the team also identified early value-engineering items that could reduce cost without degrading core performance.
"We were charged with verifying the budget based on the SD plans," Johnson said. He said the estimate accounts for potential supplier tariffs and that some previously listed items (for example, a full fire-alarm replacement) may not be required because a large portion of the system was updated in 2019.
Rowan Watson and others explained why the design separates new construction items from existing-building items: the county intends to use different bond types for each (general obligation bonds for the new construction versus other funding for existing-building work) and some maintenance items in the existing building would need replacement whether or not the expansion proceeds.
Commissioners discussed solar options and insulation and asked for a return-on-investment analysis for a rooftop solar array and for insulating the existing exterior walls. Johnson said the addition could be "future-proofed" so that the roof and pathways could accept panels later with modest up-front infrastructure.
The team said drawings are being completed with a target to return to the board on May 27 for a decision about bidding; if approved, the project would be put to bid in June. No procurement vote was taken at the meeting; commissioners asked for additional cost clarifications and for the team to provide requested ROI figures before the May meeting.
Speakers identified construction constraints including precast manufacturing lead times (14โ18 weeks) and the need to phase work to avoid disrupting ongoing LEC operations.
