ITEM SUMMARY:
On September 8, 2021, City Council approved Resolution No. 20-R-0049 authorizing the Mayor to
execute a contract with Thomas Engineering Group, LLC (TEG) for construction oversight services of
public improvements, to be constructed by Pulte Home Company, LLC, for the Trillium Farm Subdivision
Development Project, for an amount not to exceed $109,830.24. Pulte Home Company, LLC is
developing an 84 home subdivision, known as Trillium Farm, on approximately 34.97 acres of land
generally located at the southeast corner of Gary's Mill Road and Purnell Road in unincorporated
DuPage County. The Subdivision includes construction of substantial public improvements, including,
but not limited to, approximately 8,500 lineal feet of watermain and appurtenances, approximately 5,000
lineal feet of sanitary sewer main and appurtenance, approximately 7,000 lineal feet of storm sewer pipe
and appurtenances, approximately 0.87 miles of residential roadways, approximately 27,300 square feet
of public sidewalk, and a complete street light system.
With a Pre-Annexation Agreement executed between Pulte Home Company, LLC and the City of West
Chicago, said public improvements will ultimately become the ownership and maintenance responsibility
of the City of West Chicago. Therefore, it is extremely important that the City continue to have full time
inspection services conducted for all public improvements to ensure compliance with City standards.
It is estimated that the original contracted amount or $109,830.24 will be exhausted by the end of July
2021. Based on the amount of work that has been completed, which consists of the off-site phase, and
the majority of Phase 1, and the amount of work still required, which consists of Phase 2, and Phase 3, a
supplement in the amount of $66,656.84 is being requested in order to continue to provided oversight
services for the remaining public improvements. An estimate of cost is attached for your information.
The above referenced services will be paid for using Capital Project Funds (08-34-53-4225): however, all
costs incurred, plus a 25% administrative fee, will be reimbursed from Pulte Home Company, LLC per
the Pre-Annexation Agreement and Appendix G of the City Code.
