NOTICE TO PROPOSERS

ADDENDUM NO. 1: Q & A

ITB No. PW-22-151 Transportation Mobility Supplies - Delineators

This addendum changes and supersedes the language in the original ITB. Please acknowledge receipt of this addendum by signing and submitting with your proposals. Any proposer who fails to submit this addendum may be disqualified.

The City would like to remind Proposers that pursuant to Page 4, Section 5 of the ITB, the City will not be responsible for or bound by (1) any oral communication or (2) any other information or contact that occurs outside the official communication process specified in the ITB, unless confirmed in writing by the City Contact or Alternate City Contact.

The questions and answers are as follows:

1. Q: When reviewing the specs for the custom wide delineator, we will need some clarification to ensure that we identify the correct item being requested. A Type K Marker is usually an 18” high object marker with either a solid 12”x6” reflection (OM2- 2H) or (3) 3”x3” reflections (OM2-1H). Also included in the spec is black ink and 6” sergeant stripes. Doing some searching on the internet, it looks like the 6” sergeant stripes is also described as a Type R sign. One result of the search was a Sergeant Stripe Panel was an item from Impact Recovery as part of their hazard directional series. Is this the basis of the spec? If so, it looks like there are two over all dimensions, 12”x36” and 18”x36”. What dimension is the City looking to get?

A: 12”x36” is what the City is looking for.

2. Q: Approved Equals Request: Pexco City Post EAC Embedded Anchor Cup. The City

Post is a solid one-piece channelizer with an anchor cup designed for superior durability and quick replacement, and meets MUTCD, NCHRP 350 and MASH requirements for channelizing devices. Tested to remain flexible at 100 impacts at 70

MPH. The City Post can be used in multiple applications including HOT/HOV lanes, dangerous curves, gore areas, toll plazas, bike lanes, parking lots, airports, traffic circles, pedestrian walkways and emergency vehicle access. The installation of the

EAC

Embedded Anchor Cup

The City Post® Model EAC is the post that jumpstarted the ultra high performance / high durability market for flexible channelizers. Introduced in 2012, there was nothing on the market with the performance or versatility of this post, designed and built purposefully to be easily replaceable.

The City Post EAC provides the cleanest, most compact look and smallest footprint available today in the market with the largest target value. It looks great and is extremely durable.

The anchor cup allows for easy removal of the channelizer if needed. Anchor cups are mounted below the roadway grade and feature an optional removable cap. The caps keep debris out of the cup when posts are removed for winter plowing operations, or in areas where parades or festivals take place. This post is the ideal answer for installations where occasional removal is required or desirable.

The City Post EAC is a fully tested and certified channelizer.

Testing was conducted at Texas A&M Transportation Institute at 70 MPH speeds to 200 Impacts. The results are shown below:

P/N 800BASE213 4-Inch Anchor Cup

Release Date: 10/15/2014

Unit of Measure: Each

List Price: Call for Price

Construction: Cast Aluminum

Minimum core bit: 2.00”

Purpose:

The 4-inch anchor cup is intended for use in thin, aged or poorly compacted asphalt roadways.

Technical Information:

The new aluminum cup is a solid one piece design, with machined threads to accept the City Post bolt and anchor cup plug cap. The diameter is identical to the 2” cup; equipment to install is the same.

Installation Tips:

Pre-fill the large cavities in the anchor cup to eliminate air bubbles; refer to installation instructions.

EPOXY NOTE: Use two part raised pavement marker epoxy adhesive only.

When coring make sure the cutting bit is water cooled; this will help prevent drawing petroleum products to the edge of the hole during coring, resulting in subpar adhesion.

An alternative to coring is to use a rock drill which drills the hole dry; refer to installation instructions.

NOTE: DO NOT short fill the cored hole. The epoxy is the weakest component in the structure. Bad epoxy or poor application will result in poor results.

Refer to the City Post installation instructions for full details. This can be found on our website at www.pexco.com/traffic or ask your sales person or customer service to send you a copy.

1. Purpose

This is a visual guide to aid in the installation of the City Post anchor cups. This document covers the recommended procedures for installation.

2. Definitions/Tools City Post Assembly: The complete City Post assembly includes:

• Post – the taped final assembly

• Anchor Cup – Aluminum molded anchor that will be imbedded into the roadway

• Adhesive Shield – Clear sheet used to prevent epoxy from making contact with the post.

• Rubber Gasket - 0.20” rubber ring to seal the base and anchor cup

Core Drill : Any drill capable of accepting and centering a 2.1” minimum sized core bit.

Core Bit : Any masonry bit capable of creating cores a minimum of 2.1” in diameter.

Numerous Suppliers have bits: HILTI, Grainger and BOSCH, etc.

Epoxy/Adhesive : There are two adhesive systems approved for use: EAS-06 / FIRMmarker epoxy (for all surfaces) and Hilti HY 200 (concrete only). Please refer to the table below: all times are for a nominal 86oF; higher temps will result in faster times, lower temps will take longer to cure. Approximately 7 – 9 fluid ounces or 200 - 260 ml of epoxy for estimating for one install.

Work Time Cure Time Dispensing / Application EAS-06 / FIRMmarker 8 min 1 hr Qts./Gallon Hand Mixed & Poured EAS-06 / FIRMmarker 8 min 1 hr 20 oz. Cartridge / Gun Systems

Hilti HY 200A Hybrid

(CONCRETE ONLY)

4 min 30 min Cartridge system / multiple guns

Depth Gauge : Disposable tool used as a stop point for epoxy fill, see below.

Protective Gear : Glasses, latex gloves, rag for cleanup, etc…. your list may vary.

3. Preliminary Preparation – CRITICAL for new installations

Ensure that the clear adhesive shield and the black rubber gasket are installed between the City Post and the anchor cup. Screw down the anchor cup tightly until it stops.

Installation Guide and Recommendations

This shows how to create a depth gauge to speed your process along in the field. There are several ways to mark the depth, this is one simple and effective way. Please refer to the table below to determine your fill depth of epoxy.

*SFD = Stop Fill Depth

For example: using a 2.25” core the adhesive can reach a maximum fill that leaves 1.61” of air space. The air space will be displaced by the anchor cup when inserted.

Making a simple depth gauge tool using a business card:

Layout Draw two lines to be cut per the SFD dimension shown above.

Cut Make cuts on the lines drawn.

Fold Fold flap back 90 degrees.

The flap of the card should match the stop fill depth required. When filling the core hole with epoxy, stop as soon as contact is made with the edge of the flap that is inserted into the hole.

Caution: Overfilling the core hole can result in the City Po st being permanently adhered to the roadway. Do Not Overfill.

Core - opening into which adhesive and anchor will be installed

4. Coring your Holes

Guidance – the suggested core depth is 3” (2” Cup) or 5” (4” Cup). The hole will leave a jagged bottom when the core is broken off. The extra ½” of depth ensures that the minimum depth of 2.5” or 4.5” is achieved.

Check Fit – Insert the assembled City Post into a dry hole, does it sit level, if not remove more material and recheck.

Clean – Holes must be free of debris and dust, blow them out with an air hose.

Dry – if using a wet bit core drill, ensure the holes are completely dry before applying adhesive.

5. Installing the Anchor Cup Using the Hilti Cartridge System

Tools needed to proceed:

• HILTI Adhesive dispenser – Manual or electric

• HILTI Adhesive and

• Depth gauge.

• City Post Assembly

Using the adhesive dispenser, evenly distribute the adhesive into the hole to keep air bubble/pockets to a minimum.

Fill to SFD depth shown in table above.

Insert the SFD gauge into the hole. It is critical to STOP the adhesive at contact with the gauge to ensure you do not over fill the opening.

This will give you a clean and installation.

Caution: Do not overfill.

Adhesive contact with the SFD gauge should leave a little adhesive on the edge of the flap.

Backfill the flights of the 4” cup with adhesive prior to installation.

Slowly, insert and rotate the anchor cup into the adhesive filled hole and twist one full turn.

Rotating the post spreads the adhesive evenly around the anchor cup. This is critical to get a good even distribution of adhesive.

Once final depth has been reached, no adhesive should be visible around the base.

Allow the anchor and epoxy to set up, refer to the adhesive manufacturer’s directions for cure time.

Once the adhesive is fully cured you can remove the City Post from the anchor cup. If the steps are followed correctly and in sequence you should have an installation that looks very similar to this.

Finally, tighten down the City Post with the City Post wrench.

This tool is also useful to loosen the City Post when it needs to be removed. (Wrench is sold separately).

Size UP Your Application 3-inch wide posts offer 50% greater target value than narrower products.

Color Counts Fluorescent orange posts yield higher visibility in work zones

– especially at dawn, dusk, and in stormy weather. For permanent applications, post colors should match the pavement markings they supplement.

Components are Critical The fewer components a post & base have, the lower the potential for post failure. Simpler is better.

Materials Matter How many different materials make up the assembly?

Fewer components and parts typically provide greater durability and lower maintenance.

Independent Testing ABCs Independent third-party testing provides documented proof of durability under various conditions. Ask to see the complete analysis before making your choice. Results often differ on concrete and asphalt surfaces, and post top (open, flat, capped, etc.) configurations.

Flexibility vs. Failure A rigid tube must have a spring or mechanical hinge to rebound.

Designs with inherent rebound using resilient polymers, such as polyurethane, have proven to be far more durable.
