GENERAL SPECIAL PROVISIONS
ACHD PROJECT NO. 822042, GIS No: 205289
Allumbaugh St, Franklin Rd to Douglas St
1. BRIDGE AND ROADWAY CONSTRUCTION
The bridge and roadway construction will be performed using two different specifications.
The bridge will follow ITD’s 2023 Standard Specifications for Highway Construction and as modified herein in the Bridge Special Provisions. All other work will follow ISPWC, ACHD’s
Supplemental Provisions and as modified herein in the Roadway Special Provisions. Bridge limits are defined by the work as detailed in Sheets 19 through Sheet 37.
2. ACHD OWNED CONDUIT IMPACTS
ACHD-owned conduit may be shallow and located directly behind the curb or under the sidewalk. The Contractor’s method of sidewalk and/or curb removal shall be done in a manner to avoid damage to conduit and fiber. Any damage shall be repaired at the
Contractor’s expense.
3. AMERICANS WITH DISABILITY ACCESS (ADA) DURING CONSTRUCTION
The needs and control of all road users (motorists, bicyclists, and pedestrians within the highway and/or public right-of-way, including persons with disabilities in accordance with the
Americans with Disabilities Act of 1990 (ADA), Title II, Paragraph 35.130) through a temporary traffic control “TTC” zone shall be an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents. The primary function of TTC is to provide for the reasonably safe and efficient movement of road users through or around TTC zones while reasonably protecting workers, responders to traffic incidents, and equipment.
Temporary facilities, including reasonably safe pedestrian routes around work sites, are also covered by the accessibility requirements of the Americans with Disabilities Act of 1990
(ADA) (Public Law 101-336, 104 Stat.327, July 26, 1990. 42 USC 12101-12213 (as amended)).
Implementation of TTC plans and installation and maintenance of devices shall be the responsibility of the contractor performing the construction, alteration and/or maintenance of the highway or public right-of-way. Temporary traffic control for pedestrians shall meet the accessibility requirements (Standards) set forth in Part 6 of the MUTCD. When an existing continuous sidewalk or street crossing route cannot be maintained for pedestrians because of construction, either temporary walkways with curb ramps are to be provided, or the construction shall be phased to maintain access to the affected addresses. Contractors shall be allowed flexibility as long as the requirements are met.
Allumbaugh St, Franklin Rd to Douglas St | Project No. 822042 Page 3 of 40
The location of the construction project and whether or not accessible facilities are present shall also determine the extent of the needed temporary facilities. The contractor is only required to maintain practical continuity where accessible facilities already exist. On low speed rural roads that do not have sidewalks and are used by bicyclists, no additional measures are needed as the bicycles can share the available travel lanes with other traffic.
On moderate to higher speed rural roads, if a bike lane exists then it should be properly detoured, complete with signage, to provide a safe route through or around the work area.
If a road or bridge project affects vehicular traffic to a business, residence, school or any other type of pedestrian generating location with existing accessible facilities, then pedestrian and handicapped access must be maintained.
A continuous route for all pedestrians, including the disabled and bicyclists, shall be maintained at all times. When existing pedestrian facilities are disrupted, closed, or relocated in a TTC zone, the temporary facilities shall be detectable and include accessibility features consistent with the features present in the existing pedestrian facility. The temporary route should enable pedestrians to bypass the construction site while minimizing the retracing of their steps or going significantly out of their way. Additional consideration must be given to the disabled since they may not have the physical or cognitive ability to improvise (e.g. balancing along the curb or a very narrow path) or use unofficial alternatives
(e.g. using an adjacent grass surface). Temporary routes must meet the accessibility guidelines of the ADA for permanent facilities and shall be marked with the proper signage.
Should existing crosswalks at signalized intersections be closed or made inaccessible, temporary crosswalks should be painted in an accessible location. Temporary signals should include pedestrian phases.
Contractors shall not block temporary walkways with contractor parking, materials piles, signs, rubble or rubbish. Construction equipment and equipment operation must be separated from the temporary walkways. At work zones where higher volumes of pedestrian traffic or school children exist, pedestrian fences or other protective barriers may be needed to prevent access into the construction area.
Detour and diversion routes, when used for pedestrians and bicyclists, should be evaluated for the following items:
• Direct conflicts between pedestrians and vehicular traffic, work vehicles, and other work activities must be reduced with protective barriers or continuous high contrast fencing (min 36” high with a 6” high toe board). See MUTCD 6F.68 and 6D.02
• Temporary pedestrian facilities should provide safe, accessible routes that replicate as nearly as practical the most desirable characteristics of the existing facility, and parallel the disrupted route whenever possible. A smooth, continuous hard surface should be provided throughout the entire length of the temporary pedestrian facility. There should be no curbs or abrupt changes in grade or terrain that could cause tripping or be a barrier to wheelchair use. The geometry and alignment of the facility should meet the applicable requirements of the Americans with Disabilities Act Accessibility
Guidelines (ADAAG) for Buildings and Facilities. See MUTCD 6D.01 and 6D.02
Allumbaugh St, Franklin Rd to Douglas St | Project No. 822042 Page 4 of 40
• Advance information placed at appropriate distances before the work zone allowing pedestrians to make timely decisions about routes through or around the work zone.
See MUTCD 6F.14
• Transition information allowing pedestrians to find a safe path through and around work zones, which is critical when the pathway is restricted, diverted or detoured. See
MUTCD 6F.14
• Work area information assisting in safe passage of pedestrians through the work zone.
This information is needed on all pedestrian routes except detours. See MUTCD 6F.14
• Exit information directing pedestrians back to the original route. See MUTCD 6F.14
• Crosswalk placement at intersections may need additional signage, temporary striping, traffic signal modification, pedestrian signals with audible alarms if justified, proper push button height, and ramps. See MUTCD 6H.29, 6F.80, and 4E.06
• Accommodations for other transit forms (busses, trains etc.) are made. See MUTCD
6D.02
• Requirements of the ADAAG and MUTCD are adhered to.
• Access is maintained to the affected businesses and residences.

SECTION 100 – General Conditions
Add the following:
Ada County Highway District Quality Control and Quality Assurance Procedure
Definitions
Quality Assurance (QA) is defined as the process or set of processes used to measure and assure the quality of a product and/or workmanship. This encompasses ACHD’s oversight of the Developer’s/Contractor’s processes and materials. This includes review of the inspector, sampler, tester and laboratory qualifications (per ACHD Independent Assurance Program
Allumbaugh St, Franklin Rd to Douglas St | Project No. 822042 Page 12 of 40 defined below); verifying the results of the quality control and process control testing; and inspecting for conformance to plans and specifications.
Quality Control (QC) is defined as the actions necessary to produce quality workmanship and materials. QC includes, but should not be limited to, inspection of the production and placement operations, quality control and process control testing and inspection of the finished product. QC is the responsibility of the Developer/Contractor. No separate payment will be made for this work. If quality control testing is not being performed at the required frequency, ACHD may stop production of work until the tests are supplied, or ACHD determines the work can proceed.
Quality Control Testing and Process Control Testing are defined as the testing and inspections conducted by the Developer/Contractor to determine if the construction materials have been produced and placed in compliance with the project specifications and applicable standards. Process control testing is conducted to demonstrate that the construction materials being produced and used continue to meet the requirements for the product.
Independent Assurance Program (IAP) is the process provided by ACHD, through trained and certified staff, to ensure that all testing is performed correctly and testing equipment is functioning and calibrated properly.
Acceptance is determined by the QA test results, in combination with the assurance that the
Developer/Contractor has satisfied the specification requirements for materials quality and workmanship, with the exception of Superpave Hot Mix, as specified below. In addition to the specified testing results, visual inspection of the end product is also taken into consideration in determining acceptance. Acceptance will be determined by ACHD. All samples required for QA testing will be supplied by the Developer/Contractor to ACHD. Prior to obtaining a sample for QA testing, ACHD shall be notified of when and where the sample will be taken from. ACHD will determine if it needs to witness the obtaining of the QA sample. Superpave Hot Mix acceptance shall be based on ACHD’s supplement to the ISPWC
Section 814 under Part 4.2.
Construction Testing and Inspection Responsibilities
Quality Control
A. The Developer/Contractor shall be responsible for the Quality Control of all construction processes and materials quality. The Developer/Contractor will be responsible for quality throughout the construction process. Therefore, the Developer/Contractor must ensure that the materials and workmanship provided by themselves, Subcontractors, Suppliers, and
Producers meet all pertinent specifications. All tests listed under Quality Control in the
Minimum Testing Frequency Table are required for quality control, however only tests listed as Acceptance shall be used in determining pay.
B. The Quality Control laboratory must be approved by the Idaho Transportation Department.
All testing personnel and facilities used by the Developer/Contractor must be currently
Allumbaugh St, Franklin Rd to Douglas St | Project No. 822042 Page 13 of 40 certified by the Western Alliance for Quality Transportation Construction (WAQTC) and by the ACHD Independent Assurance Program. All test results must be supplied to ACHD the next working day after the test was performed. All Quality Control tests will be supplied to
ACHD directly from the lab performing the tests. Tests results shall have the ACHD project/permit number listed and be sequential.
C. Quality Control Testing must occur in a random frequency and at a minimum, at the intervals specified in the table provided in the corresponding ISPWC sections. The
Developer/Contractor shall determine the random locations. Upon request, documentation must be supplied showing how the random numbers/locations were determined by the
Developer/Contractor. All random sampling for ACHD will be done by the
Developer/Contractor and witnessed by an ACHD representative.
D. For gradation testing by the Developer/Contractor during production, each sample size shall be taken per AASHTO T2, except the sample size shall be doubled. The sample obtained shall be split in accordance with AASHTO T248, and half of it shall be marked with an ID number and tested by the Developer/Contractor. The other half of the sample shall be sealed in a canvas sack or plastic bucket, and marked with the ID number, stored in a weather protected container, and reserved for use in retesting if needed. Material shall be retained until written notification is given by ACHD that it can be discarded.
E. Acceptance, gradation, binder content and volumetrics for plant mix pavement and/or
Superpave Hot Mix asphalt shall be performed on the loose mix sampled from the roadway, haul unit, or an approved sampling method at the Hot Plant. At the start of each project the location for sampling shall be determined by ACHD and all samples for the project shall be obtained from that determined location. The hot mix sample used for asphalt binder content, gradation and volumetric testing shall be doubled in size. The sample shall be split in accordance with AASHTO R47 and half of the sample shall be used for the appropriate testing. The other half of the sample shall be sealed in a box, marked with the sample ID number, stored in a weather protected enclosure, and reserved for use in retesting if needed. Material shall be retained until written notification is given by ACHD that it can be discarded.
Quality Assurance
A. ACHD shall oversee the Developer’s/Contractor’s fulfillment of the QC requirements, and independently verify that the QC test results being submitted by the Developer/Contractor are representative of the workmanship and product quality. ACHD will also be responsible for determining general project acceptance based on conformance to the approved plan and specifications.
B. ACHD will perform random Quality Assurance testing at the intervals specified in Minimum
Testing Frequency table.
Allumbaugh St, Franklin Rd to Douglas St | Project No. 822042 Page 14 of 40
C. Acceptance of material will be based on the Quality Assurance test performed by ACHD. If no QA test is performed, acceptance will be based on the QC tests results and inspections as determined by ACHD.
D. ACHD will perform random inspections of material storage and handling practices.
Dispute Resolution
A. The dispute resolution process is to resolve differences between the Developer/Contractor and ACHD when a disagreement regarding the test results occurs.
B. When a failing QA test occurs, production may be suspended until the differences are resolved and ACHD is satisfied.
C. ACHD may run one or more tests of the split material from the QC process to help resolve differences.
D. When ACHD and the Developer/Contractor are unable to resolve the differences, a Third
Party prequalified independent lab shall be brought in to verify testing.
E. ACHD will hire the Third Party independent lab. If ACHD tests are found to coincide with the independent lab, ACHD will not grant additional contract time due to any delays in production and the Developer/Contractor shall bear the costs associated with the Third Party resolution. Likewise, if the Developers/Contractors tests are found to coincide with the independent lab, ACHD will bear the costs associated with Third Party resolution and will grant additional time for any delay caused by this additional testing.
F. For hot mix density dispute testing, cores shall be obtained by the Third Party from the same locations as the nuclear gauge tests.
Independent Assurance Program
A. ACHD practices the standards of the Western Alliance for Quality Transportation
Construction (WAQTC).
B. ACHD Independent Assurance personnel may observe testers and verify that the equipment and techniques used for the required testing are calibrated and performing accurately, per
WAQTC. During construction, it may be necessary for an IAP representative to verify the reliability of the tester by witnessing sampling and testing, and by splitting samples and comparing results.
C. All independent testing laboratories to be used shall be pre-qualified by ACHD prior to construction. To request an inspection and certification, contact the ACHD Lab Coordinator at 387-6310 to schedule. Laboratories that are currently certified by the Idaho
Transportation Department (ITD) can provide ACHD with their current certification as
Allumbaugh St, Franklin Rd to Douglas St | Project No. 822042 Page 15 of 40 confirmation of qualification. In the event that the lab is ITD certified; a facility inspection by
ACHD IAP personnel may still be required.
Price Adjustment for Non- Compliant Materials or Products
A. When material fails to meet the required specifications, they will be subject to a price adjustment or rejection. ACHD may also request a lengthened warranty period.
B. ACHD will, in its sole, discretion determine the price adjustment or rejection.
C. The determined price adjustment or rejection of material shall be applied to the quantity of material that is represented by the non-compliant test results, as outlined in the Minimum
Testing Frequency table.
Minimum Testing Requirements
A. The requirements outlined herein are the established minimum acceptance requirements for materials used in standard applications and paid for under standard bid items. For special provision items, material used in non-standard, non-roadway, temporary applications, or small quantities of materials, alternative materials acceptance requirements will be determined as discussed herein or as specified in the contract documents, or as otherwise approved by ACHD. Material placed without appropriate testing shall be subject to a price deduction or rejected as determined by ACHD.
B. Minimum testing frequencies are included in the Minimum Testing Frequency table. The
Developer/Contractor frequencies may only be altered by Change Order approved by ACHD.
ACHD may elect to increase its own testing frequency at any time. Testing frequency should be increased when accepting material from newly developed sources or those with varying results.
C. Material source approval requirements are not listed in this document. All fill and aggregate material imported to the project must be obtained from ACHD or ITD approved materials sources.
D. Based on inspection and without regard for testing frequency, ACHD may isolate and reject obviously defective material.
E. When the material is not listed in the Minimum Testing Frequency table and not identified in the ISPWC, acceptance shall be determined by ACHD.
F. When the material is required by the Contract to meet a given specification, such as ASTM or
AASHTO, acceptance of material will, at a minimum, require a manufacturer’s certification. A partial list of such material is outlined in the List of Miscellaneous Material Accepted on the
Basis of Manufacturer’s Fabricator’s Certification.
Small Quantities
Allumbaugh St, Franklin Rd to Douglas St | Project No. 822042 Page 16 of 40
A. ACHD may accept small quantities of certain materials without sampling and testing. The determination to accept materials using this provision rest solely with ACHD.
B. The following are not eligible for small quantity acceptance:
i. Concrete with a specified strength of greater than 3000 psi.
ii. Paving on the roadway with quantities above 100 ton.
C. Materials may be accepted as a small quantity if the estimated quantity is less than the minimum QC testing frequency. The small quantity exception may be used on pavement items such as; small patches, utility repairs, pavement placed outside the traveled way
(driveways, approaches, mailbox turnouts, asphalt sidewalk and curb), and temporary pavement.
D. The minimum requirements that must be met for small quantities includes; approved sources, mix design, material certifications, inspection, and a core for density acceptance of mainline and intersection paving less than 100 tons.
