Visalia, California Page 3
BASIS FOR INVOICING & LIMITATIONS
Visalia Civic Center Phase 2
North Burke Street and East Goshen Avenue, Visalia, California
BASIS OF CHARGES:
The charge schedule listed below will be our basis for invoicing.
Show-up (No site work performed) Bill R/T Travel Time + 1 Hour Work up to 3 Hrs. Bill 3 Hours
Work from 3 to 8 Hrs. Bill 1-Hour Increments
Work from 8 to 12 Hrs. and Saturdays Time and One Half Work Over 12 Hrs., Sundays and Holidays Double Time
Travel (Portal-to-Portal) Hourly
Parking and Toll Charges (if applicable) Daily Rate
FEES:
Our services will be performed on a time and material basis at unit rates listed herein. Portal -to-portal charge is based from our Fresno office. Rates/charges not specifically quoted will be charged per our published Schedule of Fees. We estimate our fees for this project at $437,933.60. This estimate is based upon our years of experience in this profession, but it is an estimate only. We endeavor to limit our charges to this estimate; however, events beyond our control may affect total cost. For example , if the work progresses quicker than anticipated , fees could be considerably less; or, if the work progresses slower than anticipated, our fees may exceed this estimate.
It is our practice to notify you if it appears our fees will exceed our estimate, but due to the timing and nature of our services and to ensure that your project is not delayed, this may not always be possible. Our invoices, however, will serve as an upd ate of our progress as well as fees charged versus our estimate.
Invoices are payable upon receipt and deemed delinquent if not paid within 30 days. Delinquent invoices may be subject to interest/service charges, and collection expenses including attorne y’s fees, at our election. As necessary to accommodate the construction schedule, BSK may use contract special inspectors to augment our staff. Inspections performed by contract providers will be billed as specified for BSK employees, herein, and at the rates included in the Fee Estimate.
LIMITATIONS:
BSK Associates provides special inspection services to assist you in verifying that the work is in substantial conformance to the project documents and as required by the California Building Code. These services shall not be construed as acceptance of the work or to relieve the contractor in any way from his/her obligations and responsibilities as outlined in the applicable construction documents. BSK assumes no responsibility for the safety of others on the jobsite or the methods and means of construction. BSK will make every effort to respond to the emergent needs of your project, to assure better service we ask that you schedule inspection/testing activities at least 24 hours in advance. To avoid show-up charges, cancel such requests at least four hou rs in advance of our arrival time. Section 1701 of the CBC requires the special inspection agency to file a final report for the project. The report will be issued upon complete reconciliation of your account. This proposal for construction services sha ll be valid for not more than sixty (60) days from the date of presentation.
