SUBJECT: APPROVE A PURCHASE ORDER TO HARRIS & ASSOCIATES IN AN AMOUNT NOT TO EXCEED $97,000 TO UPDATE THE PAVEMENT MANAGEMENT SURVEY AND ESTABLISHING A SIGN INVENTORY

FROM: David H. Ready, City Manager

BY: Public Works & Engineering Department

SUMMARY:

Approval of this item will approve the proposal and authorize Harris & Associates to update the City's Pavement Management Survey (PMS) and to establish a regulatory and warning traffic sign inventory database to comply with the federal mandate.

RECOMMENDATION:

1. Approve a purchase order to Harris & Associates, in an amount not to exceed $97,000, to update the pavement management survey and establishing a sign inventory, pursuant to On Call Agreement No. 6444

2. Authorize the City Manager to execute all necessary documents.

STAFF ANALYSIS:

In November 2013, City Council approved Agreement No. 6444 with Harris & Associates for On-Call Civil Engineering Design Services on an as needed basis. When design or consultant services are needed, the agreement authorizes staff to seek a proposal from one of four on-call firms. Council may then approve the proposal, thereby authorizing staff to prepare a purchase order for the design or consultant services. Staff sought a proposal to update the City's outdated Pavement Management Survey and establish a regulatory and warning traffic sign inventory in order to replace needed signs throughout the City as mandated by the federal government.

The last full survey of street conditions was conducted in 2008 and resulted in a comprehensive inventory of all paved City streets. The City is currently using the

5.A. rrEM NO. ___ _

City Council Staff Report July 16, 2014 -- Page 2 Approval of Purchase Order for Consultant Services Harris & Associates for Updating PMS and Sign Inventory

MicroPaver Pavement Management Software to inventory the Pavement Condition Index (PCI) of all City streets. Now that there are additional funds to use for street repair and rehabilitation, a new inventory should be conducted to assure that these funds are being spent as proficiently as possible. Since streets have different volumes of traffic, vehicle use, and environmental factors (lawn/irrigation overspray, engine oils, blow sand areas, etc.) a standard deterioration factor cannot be used for Major, Secondary, Collector and Residential streets alike. The updated Pavement Management Survey will assist the Public Works Department to prioritize the streets that are in the greatest need of street rehabilitation as well as taking into consideration proposed bicycle lanes to be installed. With the cost of petroleum products such as asphalt concrete pavement and slurry seal, on the rise, it is even more crucial to spend every dollar as efficiently as possible. Harris & Associates will take the City's existing streets catalogued in MicroPaver and adjust them accordingly to the true conditions at the time of survey, review their findings with the Public Works Department, input the data into the City's MicroPaver database, and use their experience in pavement rehabilitation to make recommendations based on the latest information.

The Federal Highway Administration (FHWA) standardizes, regulates, and publishes the Manual on Traffic Control Devices (MUTCD) which puts forth the codes behind traffic signing to promote the public's safety on public roads. In January of 2008, the FHWA adopted the MUTCD to require public agencies in charge of public streets and highways an assessment or management method to maintain traffic sign reflectivity at or above established thresholds. Agencies had until January 2012 to implement a sign assessment or management method to comply. The compliance deadline to have all regulatory and warning signs updated to the new reflectivity standards was extended by FHWA to January 2015, while the deadline to have overheads signs in compliance was extended to January 2018. The Public Works Department has adhered to the new standards as signs need to be replaced; however, there is no comprehensive inventory of all the traffic signs within the City limits. There is no reliable data on what signs still need to be replaced and updated to the new standards. A survey of all regulatory, warning, and overhead signs needs to be conducted and create an all-inclusive database so that the oldest signs can be replaced first, much like the street survey will make pavement rehabilitation more efficient. Once the City has an inventory of signs, MUTCD type code, their current conditions, and locations, the Public Works Department can implement an assessment and management method that bring the City into compliance with the language in the MUTCD set by the FHWA. Harris & Associates will survey all warning and regulatory signs using handheld GPS devices. They will then download the data into the City's GIS software, GovCiarity. This will allow the Streets Department to use GovCiarity to budget and schedule sign replacements on an ongoing cycle instead of simply replacing randomly as they are knocked down or damaged. This will put the City back on a path of systematic sign replacement to comply with the looming 2015 & 2018 deadlines.

City Council Staff Report July 16, 2014 -- Page 3 Approval of Purchase Order for Consultant Services Harris & Associates for Updating PMS and Sign Inventory

The final point is that public streets and traffic signs are City assets. These assets should be measured, catalogued, and valued for proper tax and insurance purposes. Harris & Associates has proposed completing both street and sign surveys within four months, much faster than the Public Works Department workforce could complete. The proposed cost for the update of the Pavement Management Survey and Traffic Sign inventory is $97,000.

Staff recommends the City Council approve the proposal and authorize Harris & Associates to update the City's Pavement Management Survey (PMS) and to establish a Traffic Sign Inventory database to comply with the federal mandate.

Harris & Associates .. Shaping the Future, One Project at a Time sM

Subject: Assist Inventory of Roadways and Signs

Dear Felipe:

The Palm Springs roadway network is the City's largest and most visible asset. The conditions of the roadways and traffic control measures have a direct impact on public safety and are a reflection of community pride. The maintenance and rehabilitation of roadways pavement and traffic control measures, such as road signs, has always posed challenges with limited funds and ever-changing regulations and requirements. To be eligible for funds and meet federal requirements, agencies are often required to develop condition assessments of the roadways and street signs within their jurisdiction. Inventory's that are current and updatable, make it easier to monitor performance, meet deadlines and manage limited resources wisely.

Our proposal is to perform a condition assessment and develop and update data for the City's roadways and streets signs. The project also includes developing and updating data and software for the City's roadways and streets signs and a nighttime field reviews to check signs for retroreflectivity. This proposal will provide an overview of our understanding and approach to the project and a detailed scope, fee and schedule for the proposed services.

Please let me know if you have any questions or comments regarding this proposal. Resumes for project staff are available upon request. We look forward to working with you and providing comprehensive asset management services.

Sincerely, Harris & Associates

PROJECT UNDERSTANDING

Management and maintenance of large publicly owned assets requires understanding the existing condition and the quantity or scale of the asset. With this basic information, agencies can determine the overall value of the asset, and develop maintenance and rehabilitation strategies for the future. Finding funding for the maintenance and repair of these assets is always challenging and is often dependent on assistance from local, state and federal agencies. Cities are often required to meet minimum reporting requi rements to be e ligible for funding. These requirements allow the funding agencies to monitor results and insure the funding is being used effectively to reduce further costs.

Pavement Management Program (PMP)

California Streets and Highways Code, Section 2 108.1 requires local agencies to develop and adopt a pavement management program to be utilized on local streets or highways that receive funding under the state transportation improvement programs (STIP). Additionally, in 2003, the Coachella Valley Association of Governments (CV AG) notified local governments that they were going to begin using the MicroPA VER pavement management system software to catalogue the pavement condition and mai ntenance priorities for the local Measure A funded arterial roadways in the Coachella Valley. CVAG provided the software and training to all Coachella Valley c ities. The City last performed an inventory of a ll publ ic streets and updated their PMP in 2008. The existing data is outdated and requires reassessment and updating.

Harris & Associates (Harris) wi ll provide the necessary services to update the City's PMP for the C ity's enti re roadway network, including approximately 250 centerline miles of residential and arterial streets with approximately I ,400 existing pavement management sections. Harris wil l perform condition assessments of a ll existing street segments in the City's database. Existing street lengths and widths wi ll be verified for accuracy. Existing street segmentation wil l also be reviewed and adjusted if needed based on fie ld observations. The PMP wi ll be updated using the MiroPA VER Software V6.5 (as required by CVAG). Conditions assessments wi ll be performed based on standardized methods and distresses identified in ASTM Standard 06433- 11 and the distress manuals provided with the MiroPA VER program.

Condition assessments can be performed using several different methods including: windshield surveys; walking surveys, which include surveying a representative sample of the street segment; and automated surveys. A windshield survey is proposed for this project and is consistent with inspection methods performed by the City in the past. In a windshield survey, the inspector travels in a vehicle at slow speeds and observes the pavement condition from within the vehicle. The entire pavement section is surveyed and the distress data estimated and recorded.

Condition information is entered in the MircoPA VER program and a Pavement Condition Index (PC J) is generated for each pavement segment. Once the overall pavement conditions (PC I) are updated, various

Assist Inventory of Roadways and Signs

Page 2 0 5

"what if' scenarios can be run to assist the City in planning and developing long-term repair and maintenance programs to most effectively utilize their existing budgets.

Our services will include generating a report summarizing all findings as well as the development of a pavement condition map, utilizing ex isting Citywide ACAD maps and GIS files. Each street will be assigned a color corresponding to its present condition. The maps will serve as powerful tool for understanding the overall condition of the network and presenting the findings to others.

Roadway Sign Inventory

The Federal Highway Administration (FHWA) regulates and standardizes traffic control measures across the country. The Manual on Uniform Traffic Control Devices (MUTCD) published by FHWA, sets forth basic principles of traffic s igns: namely to promote safety and efficiency on public roads. Traffic s igns are critical elements of roadways because they communicate the rules, warnings, guidance, and other roadway information that drivers need to safely and efficiently navigate the roadway network. Well­maintained signs are mandatory as they assist drivers make good decisions.

Approximately 40,000 people are killed on American roads each year. While only one-quarter of all travel occurs at night, about half ofthe traffic fatalities occur during nighttime hours. To address this this statistical disparity, FHWA has established traffic sign retro reflectivity standards. Nighttime visibility of traffic control devices is becoming increasingly important as our population ages. By the year 2020, about one-fifth ofthe U.S. population will be 65 years of age or o lder. ln general, older individuals have declining vision and slower reaction times. Signs that are easier to see and read at night can he lp elderly drivers drive more safely, retain their freedom of mob ility, and remain independent.

FHW A a lso believes that the selection of a reasonable method for ma intaining sign retro reflectivity might serve to help defend agenc ies in tort liability claims and litigation. Public agenc ies that implement and follow a reasonable method in conformance with the national MUTCD guidelines will be in a better position to successfully defend tort litigation involving claims of improper s ign retro reflectivity.

In January 2008, new requirements were officia lly adopted into the MUTCD that requires agencies in charge of streets and highways, to use an assessment or management method to maintain the reflectivity of traffic signs at or above established thresholds. Agenc ies had until January 2012 to implement a sign assessment or management method to comply with the new standard. The compliance date for regulatory and warning signs is January 22, 20 15, while overhead guide signs have a January 22, 2018 compliance date. Although guide signs are included in the minimum retroreflectivity tables shown in the MUTCD, there is not a specified compliance date for gu ide signs (inc luding street name signs) to be addressed by an agency's method. Guide signs are to be added to an agency' s management or assessment method as resources allow. Agencies need to replace any sign they identify as not meeting the established minimum retroreflectivity levels. Agencies' schedules for replacing signs are based on resources and relative priorities rather than specific compliance dates.

Assist Inventory of Roadways and Signs 0 6 Page 3

FHWA retroreflectivity standards provide flexibility for agencies to choose a maintenance method (or methods) that best fits their specific conditions. Agencies do not necessarily need to measure retro reflectivity levels of all their signs, but do need to implement a program that regularly evaluates and assesses the nighttime performance of their signs.

Once an agency implements an Assessment or Management Method, they would be in compliance with the language in the MUTCD even if some individual signs do not meet the minimum retro reflectivity levels at this point in time. Agencies must implement methods on how to maintain the minimum retroreflectivity levels.

Per MUTCD, one or more of the following assessment or management methods should be used to maintain sign retro reflectivity:

A. Visual Nighttime Inspection (Field review and rate) B. Measured Sign Retro reflectivity (Field measure) C. Expected Sign Life (Replace based on sign age) D. Blanket Replacement (Replace all at once) E. Other methods based on engineering studies.

The methods recommended are broken into two categories: management methods and assessment methods. Assessment methods involve sending personnel out to examine and assess the retroreflective performance of signs. Some agencies may find this approach to be more labor intensive and turn to management methods as an alternative. Management methods may require less field work (or none at all in some cases) but may also result in replacing some signs that still have useful life left in terms of retroreflectivity.

Based on the methods outline above and discussions with City staff, the approach for this project will be based on a combination of both assessment and management methods. An inventory of all warning and regulatory signs will be performed. The inventory can be used for current and future management of signs. In addition to the sign inventory, a Visual Nighttime Inspection will be performed is assess the retroreflectivity of all warning and regulatory signs. The following minimum data will be collected for each of these regulatory and warning signs:

I) Sign Type and Size (MUTCD designation such as R 1-1) 2) Sign Location (Street name and address or coordinates) 3) Date sign was installed (Sticker of back of sign) 4) Overall Condition (Good, Fair, Poor) 5) Nighttime visual inspection and assessment of retroreflectivity

Sign inventory information will be collected using hand held mobile devices such as mobile phones or tablets. The data will be input in the field and stored using 'GIS Cloud' technology. All collected data will be downloaded and input into the City's preferred digital mapping program 'GovClarity'.

~ PJ~JJ~~ MAP ,.J GovCiarity GovClarity is a digital mapping product that the City is already using. City staff is already familiar with this program, which should allow easy access to the newly developed sign inventory data. Use of this program will allow the City staff to obtain data on each street sign using the graphical map interface. Staff

will also have the ability to update sign information data in GovClarity as signs are maintained and replaced.

SCOPE OF WORK

Pavement Management Program (PMP) Scope

Task Pl: Project Orientation

At the start of the program, Harris will meet with the City to discuss the project's goals, field data collection method, and the project schedule. This meeting will ensure that all parties understand all aspects of the work before any work begins.

Key components of these discussions will be the extent of the pavement condition survey and the work completed since the last survey.

At this meeting, Harris will expect to receive the following data or items from the City: • Current detailed City map showing all public streets and alleys within the City that are to be

surveyed. (Already Provided) • All existing available data, such as the City's existing pavement management data (in electronic

format), street classification, ADT, etc. (Already Provided) • Street maintenance history data, including slurry seal and overlay projects. • City's GIS street centerline shape file along with the city limits. (Already Provided)

Harris' project manager will submit project update reports and communicate with the City's project manager as needed to facilitate the project.

Task P2: Field Data Collection

Using the PAVER Distress Identification Manuals developed by the Army Corps of Engineers and included in the PAVER version 6.5 package, Harris will conduct a field inventory on all streets, approximately 249 centerline miles, for a total of 1,385 pavement management sections within the City.

The following data will be collected or confirmed in the field:

• Name of the street

• Limits of the pavement segment (from I to)- A description of the limits of each pavement section. The limits will note the side of the boundary street from which the segment was taken (e.g., "N/S MAIN ST" refers to the north side of the intersection at Main St). If the limits exist between intersections, then the description may be an address, post mile marker, or a distance from a known point of reference (e.g., "500' N/0 MAIN ST").

• Measure street length and width - Street lengths will be measured along the street centerline over the entire length of the street. At intersections the length of two of the intersecting streets will extend to the center of the intersection and the measurement of the remaining two segments will be cut short of the intersection by Y, of the intersecting street width (lip of gutter projection of the intersecting street). This is will insure that the area of the intersections are not counted twice due to overlaps. Street width will include only the AC or PCC pavement area and typically are measured from lip of gutter to lip of gutter, face of curb (if no gutter) or edge of pavement.

• Number of travel lanes - The number of travel lanes, excluding parking lanes. This would include the double left tum lane in the center, if applicable.

Page 5 Q 8

• Surface type- such as AC, PCC, gravel, or dirt.

• Field VerifY Street Lengths and Widths

• Surface distresses

The governing document in performing condition surveys for the City are the PAVER Distress Identification Manuals developed by the Army Corps of Engineers. Both asphalt concrete (AC) and Portland cement concrete (PCC) pavements are included in this protocol. The following distresses are collected for each pavement type.

As11halt Concrete (AC) Pavements Portland Cement Concrete {Jointed) I Alligator (fatigue) cracking I Blowupfbuckling

2 Bleeding 2 Corner breaks

3 Block cracking 3 Divided slab

4 Bumps and sags 4 Durability ("D") cracking

5 Corrugation 5 Faulting

6 Depression 6 Joint seal damage

7 Edge cracking 7 Lane/shoulder drop off 8 Joint reflection cracking 8 Linear cracking

9 Lane/Shoulder drop off 9 Patching (large) and utility cuts

10 Longitudinal & Transverse cracks 10 Patching (small) 11 Patching and utility cut patching II Polished aggregate 12 Polished aggregate 12 Popouts 13 Potholes 13 Pumping 14 Railroad crossing 14 Punchout 15 Rutting 15 Railroad crossing 16 Shoving 16 Scaling and map cracking 17 Slippage cracking 17 Shrinkage cracks 18 Swell 18 Spalling (comer) 19 Weathering 19 Spalling Goint) 20 Raveling

At a minimum the inspectors are primarily concerned with eight distresses: alligator cracking, block cracking, longitudinal and transverse cracking, patches or utility repairs, potholes and weathering and raveling.

A visual survey of I 00 percent of the surface, performed by driving the street at low speeds, of each segment will be made and its condition recorded based upon actual surface conditions and physical characteristics of the segment, based on the field distress manuals. By surveying 100 percent of the surface area, a more accurate indication of road conditions is generated, thereby generating a more accurate estimate of maintenance and rehabilitation costs. The specific types of distresses to be measured will be determined prior to the start of the inventory based upon discussions with City staff during the project kick-off. Where appropriate, Harris will provide pictures of areas exhibiting extraordinary distress.

Task P3: Pavement Management System Data Entry

Harris proposes to continue using the APWA Micro PAVER software for the City's PMP project. A large number of Southern California agencies currently use this software. As the City may be aware, this software package is Windows based and provides the following features:

Assist Inventory of Roadways and Signs

Page 6 09

• Fast database operations • The ability to store scanned or digital images • Built-in field inspection capability • Pavement inventory including limits, features, and geometry oftbe segments • Allows the City to manage its pavement network by tracking street conditions, identifY cost­

effective maintenance strategies, developing capital improvement budgets, and tracking historical work-loads on each street segment within the City.

Micro PAVER has the capability of:

• Defining maintenance strategies, unit costs, and deterioration curves. • Developing budget and cost infonmation which can be readily changed to reflect annual changes

in fiscal requirements, and to reflect multi-year budgeting needs (i.e., "what if' budget analyses comparing the impact on maintenance programs and service levels based on various funding levels and cost benefit analysis.

• Demonstrating graphically (i.e., pie charts, bar charts, etc), and in tabular format, the overall condition levels for the entire street network based on the above-mentioned codes.

• Analyzing pavement condition and developing priority lists. • Entering and storing completed maintenance projects to keep an archive of all work-related

activities relative to each pavement section. • Identifying improvement strategies for each pavement section.

Harris will enter all data collected into the Micro PAVER pavement management database. A Pavement Condition Index (PCI) will be calculated for each street surveyed after the data entry has been completed.

Upon completion of the data entry, a condition report will be generated showing each street section and its current PCI. The PCI is presented using a scale of 0 to 100, where 0 is the worst condition and 100 is the best condition.

The condition report from the database results, in Excel fonmat, will be transmitted to the City for review and discussion.

An electronic copy of the updated Micro PAVER database will be provided to the City.

During this data entry phase additional user defined data fields can be added so the data can be sorted or evaluated in different groupings. The City has requested that Neighborhood Organizations (N.O.) fields be added to the existing street segment data. The addition of the Neighborhood Organizations will be added to the existing MicroPA VER data.

Task P4: Define Repair I Rehabilitation Strategies

Following review of the pavement condition inventory data, the various repair/rehabilitation strategies will be discussed. Harris will review the City's existing repair and rehabilitation strategies, and assist the City witb development of the most cost effective preventative maintenance, repair, and rehabilitation strategies.

The strategies will be developed based on road class, type of surface, and specific needs of the City. This will confinm that the recommended strategies are based upon the selection of appropriate activities, unit costs, and life cycles for the City.

Task P5: Develop 5-Year Capital Improvement Plan

Once the repair/rehabilitation strategies have been defined, Harris will identifY the recommended maintenance and rehabilitation projects for each street over a 5-year period. The recommended projects

Assist Inventory of Roadways and Signs

Page7 10

would be identified on the basis of several criteria: cost/benefit analysis, present pavement conditions, current and unconstrained funding levels, future routine and major maintenance needs based on projected deterioration rates, and desired levels of service.

The primary emphasis of this task is to maximize the programming of street maintenance projects using the most cost-effective maintenance strategies available, and taking into account a life cycle cost analysis of each strategy recommended. Following this analysis, project lists would be generated for three (3) funding levels:

• Unconstrained funding level • Zero funding level; and • City's current projected funding level

In this way, if available funding is less than required for completion of recommended projects within a given year, it will be easy to determine which projects can be deferred with the least impact on current pavement condition and future rehabilitation cost, in addition to showing the total backlog of street maintenance work.

The funding scenarios will be re-run twice (2), based on the City's comments on the Draft Report.

Task P6: Final PMP Report

Harris will prepare an executive summary report that will summarize: the objectives for a sound pavement management program, the field data collection techniques and data necessary to generate a reliable pavement management program, the assessment and evaluation results, and present condition of streets evaluated and rehabilitation and maintenance strategies proposed. Harris will also provide our conclusions and recommendations within the executive summary.

The Pavement Management Program Report will provide a summary of the findings from the condition survey with the corresponding recommendations for the implementation of the most cost effective maintenance program.

The report will be prepared in a format that will utilize the information gathered and analyses performed by Harris during the course of the project. The report will provide the City with information on:

• Current pavement conditions shown in tabular format (best to worst condition) for all street classifications and surface types.

• Recommended maintenance and rehabilitation strategies. • Project schedules and associated budgets (i.e., adjusted for inflation within the software based on

user selected inflation factors) for the entire network, as well as each street segment, for each fiscal year over the seven year period.

• Priority projects that should be scheduled for immediate maintenance, based on existing conditions.

• An analysis that allows the City to measure and understand the impact on and cost of deferred maintenance for the City street network.

Task P7: PMP Segmentation and PCI Map Generation Harris will produce a pavement condition map for the PMP from existing GIS street centerline shape file. The map will show the condition of each street in the roadway system. The segmented PMP shape file will match with the existing street section definitions from the Agency's pavement management program. Currently the City's PAVER inventory has 1,385 PMP sections (249 centerline miles of street network). Further discussions about the condition map requirements will be discussed at the kickoff meeting.

City Responsibilities

1. Provide access to historical budgets, work reports, bid sheets, and unit costs related to

pavement maintenance within City.

2. Provide maps in ACAD or G!Sbase map file with City limits file.

Sign Inventory Scope

Task Sl: Data Collection

One of the challenges in providing a scope of services for a sign inventory is estimating the potential number of signs that will require inspection. For the purposes of this proposal some assumptions need to be made and stated to establish a basis for this effort. The following was assumed:

I) Each arterial segment typically has 3 to 4 warning or regulatory signs per half mile segment. 2) There are approximately I 20 arterial segments; therefore there are approximately 350 to 500

signs on arterial streets. 3) There are approximately 1,400 street segments in the PMP. If 120 of these are arterial segments

than approximately I ,300 are residential streets. 4) It is assumed that half the residential segments have stop signs for a total of approximately 600

signs in residential areas. 5) It is assumed that approximately 1,100 signs will need to be inventoried.

Data collection will be performed using hand held mobile devices such as smart phones or tablets. Data will be entered in the field using pull down menus for the various sign types and attributes. At a minimum, is it assumed the following attributes will be collected during the field inventory:

I) Assign a unique ID for each sign inventoried 2) Sign Type and Size (MUTCD Designation) 3) Sign condition (Visual- Good, Fair, Poor) 4) Sign location (By GPS locating or by street address) 5) Sign installation date (Date on back of sign) 6) Take a Goetag photo of each sign

Data will be entered in the field and stored using the 'GIS Cloud' mobile data collection platform. Advantages include; data can be accessed by staff in the office as it is being collected in the field and also minimizes the need for a data storage device in the field.

Task S2: Data Management and GovCiarity Graphical Interface

Sign data collected in the field can be exported via a comma-separated values (CSV) file and imported directly into the City's existing version ofGovCiarity (using one of the City's existing licenses). Once the data is delivered to the City, City staff will have the ability to use and enhance the data via the GovCiarity platform in the future.

Task SJ: Summary Report of Sign Inventory Findings

A report will be prepared summarizing the findings of the field inventory. Information will include basic tables and charts illustrating the total number and types or signs. Average sign age and condition will be provided. The total estimated replacement value will be provided as well as cost needed to replace deficient or damaged signs.

Assist Inventory of Roadways and Signs

Page9 L2

Task S4: Retroreflectivity Assessment

Visual nighttime inspection is a common method for maintaining traffic sign retro reflectivity. The method is simple and requires a trained or experienced inspector to view traffic signs from a moving vehicle during nighttime conditions. The inspector subjectively concludes if a given sign passes or fails. Visual nighttime inspection can be performed with one individual, but is more effective with two; a dedicated inspector monitoring and recording sign fai lures and a focused driver following a predetermined inspection route. The fo llowing procedure wi ll be included in nighttime assessments and are based in part on recommendations* outlined by FHWA:

I) The visual inspection will take place during typical nighttime conditions and that viewing not be affected by adverse or inclement weather such as fog or rain.

2) Sign failures and noteworthy comments wil l be documented in a standardized procedure. 3) Inspector will be at least 60 years old* 4) A sport utility vehicle, model 2000 or newer will be used*

The inspector will document the evaluations by means of the ' GIS Cloud' solution and standardized forms. The duration of a nighttime inspection session will be limited so inspectors do not become fat igue. Inspections will be consistent with agency procedures and be able to document when the nighttime sign inspections have been completed.

SCHEDULE AND FEE

The fo llowing is the pro posed schedule for both project e lements. We have staff avai lable now and can begin this project upon receiving a forma l notice to proceed. Fees will be at the not-to-exceed lump sum cost shown below. Harris reserves the r ight to negotiate mutua lly acceptab le contract language.
