HILL PARK IMPROVEMENTS PROJECT
Dear Mr. Liu:
LAE Associates, Inc. (LAE) is pleased to have the opportunity to submit this proposal as part of our On-Call contract with the City of Diamond Bar (City) to provide the City with Construction Observation Services. LAE will provide a Senior Construction Observer (SCO) to inspect the subject project. The project consists of and includes new accessible parking stalls, new accessible concrete walks and paving, new playground equipment and wood chip play area, new utility extension for contractor supplied and installed prefabricated restroom building, new landscaping/irrigation modifications; and other incidental and appurtenant work necessary for the proper construction of the Maple Hill Park Improvements Project.
The City opened the sealed bids for the project on July 11, 2024, and a total of thirteen (13) bids were received. The City Council awarded the construction contract to Siterep Construction Services, Inc. in the amount of $1,689,766.33 on August 6, 2024. Per the Contractor’s baseline schedule, the project construction is scheduled to start in October 2024 and will be completed by January 2025.
LAE will assign Mamoun Aldwir, Senior Construction Observer (SCO), as the prime inspector, and Ned Shaffer, Senior Construction Observer, as an alternate to inspect the project. Mr. Aldwir has been providing over thirty-three (33) years of Public Works inspection services for the Cities of Placentia, San Dimas, El Monte, La Mirada, Lomita, Water Employee Services Authority (WESA), as well as Diamond Bar. Mr. Shaffer has over thirty-five (35) years of experience working on infrastructure projects. LAE employees have experience in the public sector and know the intricacies involved in this project’s line of work. The following are the Construction Observers’ recent experiences with similar projects:

• City of Rosemead – Dog Park at Garvey Park, $640,000. • City of Diamond Bar – Area 3 Residential and Collector/Arterial Streets Rehabilitation, $9,369,000.
• City of Lomita – Street Reconstruction of Zones C&F, $2.25 million. • City of La Mirada – Phase 6A Residential Street Rehabilitation, $4.6 million. • City of El Monte – Phase I and II Slurry Seal/Overlay and Street Pavement Resurfacing Project, $5 million.
• WESA – Parking Lot and Street Improvements, $1.2 million.
Scope of Work
LAE’s SCO will be acting as an extension of the City staff. He will thoroughly review and understand the contract documents, bid proposal, visit the sites, and attend a kick-off meeting with the City’s PM prior to the pre-construction meeting as well as the preconstruction meeting. After the pre-construction meeting, Mr. Aldwir will coordinate with the City’s Project Manager to ensure the City designer approves all submittals.
During construction, LAE’s SCO will work with the City staff, Contractor, Utility Companies, and other parties. He will have a set of the latest plans/specifications, Standard Specifications for Public Works Construction, 2021 Edition of the Standard Plans for Public Works Construction (Greenbook), 2024 W.A.T.C.H. Manual and other standards onsite. He will provide the required construction observation services, monitor the project schedule, cost, quality, and quantities. Mr. Aldwir will ensure all design changes have been approved and CCOs have been issued.
Construction Observation/Inspection
LAE’s Senior Construction Observer will:
• Attend all meetings.
• Check for compliance with plans, specifications, and safety concerns. • Ensure construction has minimal impact to residents, pedestrians, business and industrial areas, school children, accesses, and travelling public. • Confirm compliance with Americans with Disabilities Act (ADA) guidelines. • Verify contractor’s construction stakes and other surveying activities. • Verify for NPDES compliance and Best Management Practices. • Ensure proper coordination/scheduling for sampling/testing. • Retain delivery tickets and Certificates of Compliances. • Redline the plans; designer will draft “As-Built” plans. • Have copies of the contract and other documents.
• Take project sites/construction activity photos.
• Communicate with utility companies and other agencies. • Prepare Daily Reports, in the City’s format, to be submitted to the City on an on-going basis, which will consist of:
▪ Contractor working hours on the jobsite.
Construction Observation services for the Maple Hill Park Improvements Project
▪ Contractor and subcontractors’ personnel/equipment on jobsites. ▪ Weather conditions and impact on the work.
▪ Communications with prime contractor and other parties. ▪ Daily use of contractor’s and subcontractors’ equipment. ▪ Work progress, observations, and photographs.
▪ Delivery of materials to the project sites.
▪ Observed or foreseen delays and contractor’s action plans. ▪ Visitors who come to the job sites with interest in project. ▪ Work activities, construction progress, quantities measurements.
Engineering Coordination: LAE’s Engineering Coordinator will print the plans, specifications, contractor’s proposal, approved submittals, and organize them for our inspector, process time sheets, upload LAE Inspector(s) payrolls to the Department of Industrial Relations (DIR) site on a weekly basis. LAE will calculate the required training payments for the LAE Inspector(s) worked hours, prepare the required payments for the LAE Inspector(s) worked hours to the California Apprenticeship Commission and process the required Payments. In addition, the Construction Inspector’s daily reports will be reviewed, formatted, and processed into the project files.
Material Testing (Optional): Materials Sampling/Testing will be provided by GeoAdvantec, Inc. (GAI) of San Dimas. GAI, with Caltrans Certified Laboratory and Technicians, will provide the required Geo-technical and Quality Assurance/Quality Control (QA/QC) services. GAI has assisted the following LAE clients with similar projects since 2016: Arcadia, Azusa, Chino, Compton, El Monte, EVMWD, Lomita, and Montclair.
At the Pre-Construction meeting, the City requested to have material testing services available to review footings, concrete, and other project components.
Labor Compliance: LAE will ensure the prime Contractor and Subcontractor(s) submit Certified Payrolls and other related documents in a timely manner. We will review the certified payroll records, interview the Contractor/sub-contractors, and provide reports.
Labor Compliance services will be performed by LAE’s subconsultant, GCAP Services.
Since 2016, GCAP has assisted LAE’s client Cities of Arcadia, Azusa, Chino, Compton, El Monte, Laguna Niguel, Lomita, Montclair, Norwalk, Seal Beach, and Ventura. Per the City, Labor Compliance Services will be needed due to the project’s funding source(s).
Final Walkthrough: On an on-going basis, preliminary punch list(s) will be prepared.
Then, upon completion of the construction, a final walkthrough will occur with all involved parties. A punch list will be prepared and given to the contractor and City. Inspections will be conducted again to confirm that incomplete work has, in fact, been completed.
Project Completion Report: Upon acceptance of the project by the City (various departments/divisions) and impacted utilities, the SCO will submit final redlined “AsBuilts,” test results, and other correspondence to the City.
Fee: LAE’s fee to provide the requested services will be as follows:
Construction Observation services for the Maple Hill Park Improvements Project
* Based on the Contractor’s twelve (12) week or sixty (60) working day construction schedule, starting October 14, 2024. Per the City, the SCO will be on site three (3) out of five (5) working days. ** SCO Overtime (OT): Should the contractor work overtime or on Saturdays.
Once again, thank you for providing LAE with an avenue to be of service to the City of Diamond Bar. Should you have any questions, please feel free to contact me with any inquiries regarding this proposal at 714-993-2840 or [email protected].
