Title
Consider Authorizing The City Manager To Approve Change Order #1 With Turner Construction Company To Modify The Scope Of Construction To Provide A Structural Steel Staging Canopy, Automated Sensor Site Lighting, And Bicycle Impound Screening Fence For The Police Department Headquarters Facility In An Amount Of $257,362.00 For A Revised Contract Amount Not To Exceed $13,731,235.00.
Body
BACKGROUND:
By Council approval on October 13, 2015, the Engineering Department executed a contract with Turner Construction Company for construction of the new Carrollton Police Headquarters facility. On February 16, 2016, Council authorized the City Manager to approve a Guaranteed Maximum Price (GMP) of $13,473,873 for construction of the new facility which included allowances of $138,200 for fabric staging canopies and $216,200 for secured perimeter fencing. Construction of the facility began in late February and is currently on schedule for a May 2017 completion.
Subsequent to GMP execution, the Police Department expressed a desire for a more durable structured metal canopy that would not only offer a higher degree of protection from the elements but a substantially longer service life that is more comparable to the building. A structured steel canopy was originally planned for the facility but scaled-back to a fabric canopy due to budget considerations.
The Police Department also requested that site lighting be controlled by motion sensors rather than a typical timer system. Under the motion activated system, lighting would be maintained at a minimal level during non-daylight hours, then increase in intensity when movement is detected. The benefit is recognized by increased safety due to a higher degree of light intensity when a person is present in the parking lot, reduced energy costs, and reduced light pollution when the parking lot is not occupied.
FINANCIAL IMPLICATIONS:
Turner Construction Company has submitted a change order to provide all aforementioned construction activities in the amount of $257,362 as outlined below. This increases the original construction contract from $13,473,873 to $13,731,235 or 1.91%. Turner has not requested additional construction time for these modifications. Funding is available for all construction in the Police seized funds.
Structured steel canopy and motion sensor site lighting $395,562
Credit for fabric canopy allowance ($138,200)
Change Order No. 1 Total $257,362
IMPACT ON COMMUNITY SUSTAINABILITY:
This project will contribute to community sustainability by providing adequate long-term police facilities, and ensuring continuance of effective law enforcement operations for the citizens of Carrollton.
STAFF RECOMMENDATION/ACTION DESIRED:
Staff recommends City Council authorize the City Manager to approve change order no. 1 with Turner Construction Company for the construction of the Police Headquarters Building and Site Elements in an amount not to exceed $257,362, for a revised contract amount not to exceed $13,731,235.
