Recommended Action
RECOMMENDATION:
Staff recommends that the City Council:
1. Approve final payment in the net amount of $156,875.80 to Creative Home, Inc. DBA CHI Construction for the City Yard Cover Project;
2. Formally accept the City Yard Cover Project as complete and authorize filing of the appropriate Notice of Completion;
3. Approve release of retention in the amount of $33,975.16
FISCAL IMPLICATIONS:
Five separate enterprise funds including Capital Improvement, Water, Stormwater, Wastewater and Refuse in the total amount of $886,180 have been appropriated by City Council for this project. Total expenditures for the subject project are $778,695. A summary of budget and expenditures is provided in Attachment 1.
BACKGROUND:
The upper level area of the City Yard maintenance facility is utilized as a bulk material storage area for temporary storage of construction, landscaping and waste disposal materials as shown in Attachment 2. Construction and landscaping materials are used for various, daily City maintenance projects and for emergency repair operations. In addition, this area serves as a temporary storage facility for the transfer of debris collected from street sweeping, catch basins and Continuous Deflective Separation (CDS) storm drain units; as well as, recycling bulk construction demolition materials. The waste disposal and construction recycle materials are divided into separate bin areas then removed per truckload by the City’s waste hauler on a routine daily basis. There is also a single bin area which is used for what is considered refuse.
On November 18, 2014, City Council authorized the City Manager to award a construction contract in the amount of $672,262 (and additional construction work, if necessary, in an amount not-to-exceed $67,738) to CHI Construction for the City Yard Cover Project. In addition, City Council authorized the City Manager to execute an agreement for professional inspection services with Hamilton and Associates, Inc. for construction management and inspection services.
This project qualified as an NPDES stormwater, pollution prevention Best Management Practices (BMP) in addition to those already in place at the City Yard.
DISCUSSION:
Construction started on January 26, 2015. The scope included construction of new canopy structures, pavement, sewer and storm drain improvements. The project was completed in January 2016. The canopy structures portion of the project involved the construction of two separate steel frame roof canopy structures over the designated material storage bin areas to prevent the bulk materials from polluting the localized storm water runoff for this site. New concrete divider wall partitions were constructed in place of the broken and ineffective block walls to keep materials separated.
The pavement portion of the project included the reconstruction of the fifty-year old cracked and failed pavement that previously covered the site to adequately provide the proper drainage and handle the heavy equipment traffic loading.
The sewer portion of the project involved the construction of a new sewer drain line which will collect water that is routinely captured with the collected solids from catch basin cleaning, CDS storm drain unit cleaning and street sweeping then convey the nuisance water into the City’s existing sewer system; subsequently, reducing the amount of ponding water at the site.
The storm drain portion of the project included the reconstruction of the undersized and deteriorated stormwater catch basin and pipeline at the site. This catch basin was fitted with a Los Angeles County certified connector pipe screen (CPS) full capture device in order to prevent trash and debris from entering the storm drain. This full capture device added a third tier of storm drain pollution protection to the City maintenance facility in addition to the existing clarifier and CDS storm drain unit that exists on the lower level of the City’s maintenance facility.
Change Orders
All contract line items have been accounted for in progress payments to date. The final payment for this project also includes one additional work item for asphalt concrete pavement restoration, and two extra work items for formwork reconstruction and a foundation modification. The additional pavement work was paid through added quantities in the Contract proposal. The extra work items were not included in the original Contract proposal but paid through a negotiated lump sum cost. The total cost of the change orders for additional and extra work was $19,298 and was within the approved contract contingency.
Liquidated Damages
Construction of the project was completed on January 15, 2016. Since the Contractor did not complete the work within the 120-working day contract time allotted, plus the time extensions granted in the Change Orders explained above, liquidated damages were assessed per the Contract Special Provisions. A total of $50,000 was deducted from the final contract amount.
ENVIRONMENTAL REVIEW:
The California Environmental Quality Act (CEQA) requires public agencies to document and consider the environmental implications of their actions. Based on the scope of work, the City Yard Cover Project was categorically exempt pursuant to Section 15303, Class 3(e). A Notice of Exemption was filed with the Los Angeles County Clerk’s office for the project.
