Overview
Incidental Construction covers a large variety of infrastructure. These items are generally used and seen in the right of way and part of the City's infrastructure. Some items covered under this section include sidewalks, driveways, rock blankets, fencing, guardrails and other assortment of items that can be project specific. It will be important to be familiar with all the various types of construction. Review of approved submittals and manufactures recommendations will be of the upmost importance.
Sidewalk and Curb Ramps are to be ADA compliant.
Specifications/Contract Documents
Specifications will be either project specific or standard MoDot. APWA Specifications could also be used on the project. It will be up to the inspector to determine which specification is followed or a hybrid of specifications.
Submittals
General Requirements:
Review plans and specifications , (special provisions and addendums).
Certifications:
Review the materials being installed and any certification requirements. Insure that delivery tickets depict the approved material prior to placement. Warn the contractor that any material that does not meet those required by contract and has been pre-approved will cause non payment until removal and replacement with approved materials are in place.
Traffic Control
Review the traffic control plan. Verify if time schedules are addressed in the contract and all detours needed are MUTCD approved. Usually the City's Traffic Engineering Department approves all plans prior to construction starting and the inspector shall verify compliance.
Pre-construction Video:
Review the videos of the project. Check for clarity and being in compliance of the contract. On large projects, phases are videoed individually to reflect "real time".
Field Observations
Testing:
Contact the predetermined testing lab that the City has set up to when work will be taking place and locations. Advance notice is required. Work closely with the Contractor for scheduling.
Have proctors taken on the soil or base rock used for compaction.
Review the frequency on the test requirements. You will find this in the Quality Control- Quality Assurance portion of the contract documents. Development inspectors shall refer to the City's Design and Construction Manual.
When concrete is being placed, an entrained air test, slump test, and cylinders shall be taken. Follow the American Concrete Institure for proper procedures. Placement and curing details is described in the contract documents.
A compaction test needs to be taken on the sub-grade before material is placed. This is for the first and each and every lift after that. No material shall be placed on lifts of material not tested unless other arrangements have been previously approved.
Review the temperature requirements for any material being placed. Asphalt, concrete, flyash, etc. all have parameters of temperature ranges.
Discuss the scheduling with the testing lab and what test are required. This should be addressed in the Pre-construction meeting as well as in the field to the lab technician.
Review the testing guidelines for Quality Control (QC) and Quality Assurance (QA)
Field Observation:
Identify the location of right-of- way lines and easements on the project.
Check daily that the traffic control is set up correctly.
Identify that the correct material is being placed and installed correctly.
Review the testing requirements and is the correct testing being performed.
Take photos of the progress of work and any unforeseen damage to property that may have happened while the work was taking place.
Perform wage rate interviews every two weeks if required.
Keep a punch list during the project of any items that need to be addressed and at the end of the job have a walk through with the contractor to discuss any outstanding issues that need to be completed before final acceptance of the project.
Fill out the field book daily on the work completed and review the quantities with the job supervisor or foreman.
Documentation
Documentation:
Set up your field book for documentation. Keep it up to date daily. This is one of the inspectors's primary duties. Material records are to be logged at the same time.
Pay Application:
Document all of the pay items on the contract that have been completed so the information can be given to the project manager for a pay application.
Confirm pay items with Contractor Supervisor for his input of quantities prior to submitting to the construction project manager. This eliminates errors and saves time in the pay application process.
