CONSIDER APPROVAL OF 97 -XX A _ DING BID FOR
FIELD AND SECURITY LIGHTING AT PONDS PARK.
SEPTEMBER 15, 1997
At the September 2, 1997 meeting, the Council considered
award of bid for athletic field and security lighting at
Ponds Park. The Council heard presentations by the City
Manager, City Park and Recreation Director, and the
City's Engineering Consulting Firm, Wunderlich-Malec
concerning: 1) Neighborhood meetings held with residents
whose properties abut the athletic fields and 2) How
consultants prepared specifications for a lighting system
that would address concerns raised by the City Staff,
Parks Advisory Committee, and residents that glare and
light spillover not affect residential property.
Also at the meeting were the national representative of
Hubbell Lighting Systems, area representative (R.L.
Mlazgar & Associates), who, through their attorney,
challenged the specifications pertaining to the lighting
fixtures. Specifically, the Hubbell representatives claimed
that the specifications were too narrowly drawn and the
objective of minimizing glare on adjacent properties could
have been achieved by less restrictive specifications. They
further claimed that the City's consulting engineer,
Wunderlich-Malec, has consistently in previously bid
projects, named Hubbell's competitor, Musco lighting, as
the product of choice.
In response to the allegations made by Hubbell
representatives, the City Council deferred action on the
award of bid for the athletic field and security lighting
project at Pond's Park. The staff was directed to respond
to issues raised by Hubbell representatives at the meeting
before the Council takes action to award bid.
Since the Council meeting, additional correspondence has
been received from the City's consulting engineer,
Wunderlich-Malec. It is attached for Council information.

AN EQLAl OPPORTL'NITY E',,1PlOYER
The staff has had the opportunity to discuss the issues
raised by Hubbell representatives at the September 2
meeting and in correspondence. The information derived
from discussions with Wunderlich-Malec are shown in this
memorandum. In light of the responses which Wunderlich-
Malec has offered we continue to believe that the
specifications as prepared by the Consulting Engineer met
the City's objectives and neighbors' concerns and that such
specifications were necessary and essential to meet these
objectives.
Consequently, the staff continues to recommend that the
firm of Electric Service Company of Minneapolis, Inc. be
awarded bid for the athletic field and security lighting at
Pond's Park in the low-bid amount of $310,408.
DISCUSSION:
The information set forth below is derived from a recent
meeting with the City's Consulting Engineer, Wunderlich-
Malec, specifically Wally Sharp and Jim O'Brien. It
continues to be our opinion that it is important for the
City to respond to the concerns of the neighborhood by
providing a lighting system that minimizes impacts of
light spill and glare on their properties from the athletic
field lighting for present homes and for future
developments. Also attached to this staff report is a letter
from Craig Gallop of Sports Technology, Inc. representing
Musco Lighting, Inc. commenting upon the allegations
made by Hubbell representatives and the bid
specifications and their intent.
We have consulted with Wunderlich-Malec and they have
reaffirmed and represented to us that the bidder's use of
Musco lighting fixtures in the specifications: 1) provides
the least degree of spillage affecting adjacent properties
developed or to be developed around the park, 2) places
the most light most consistently on the athletic field,
which is crucial for safe athletic play, 3) entails the least
glare, 4) is upgradable without using custom products, 5)
facilitates ease of maintenance.
Wunderlich-Malec has addressed each of these
factors with the following information:
1) Musco lil!ht orooosal orovides the least del!ree of soilla!!e
affectinl! adiacent orooerties:
Shown below is a table provided by Wunderlich-Malec
which compares the foot-candle data supplied by Musco

and Hubbell which represents the worst case scenarios of
light spillage on neighboring residential properties. The
attached aerial map shows the location of the houses.

fields)

The consultants point out that the foot-candles are
measured at 75 feet from the fields edge, which is just
short of the back door of this property.
Address/Location

The consultant indicates that the foot-candles are
measured at 150 feet from the field's edge, or on the front
side of the houses. The back side of the houses is 110 feet
so foot-candles measured there will be higher than on the
front side of the home.
According to Wunderlich-Malec, the difference in lighting
between 4.3 and 3.07 or between 1.6 and .92 foot-candles
is approximately 40-70% in lighting intensity.
So that Council can observe the difference first-hand,
Wunderlich-Malec has, using a light meter, identified and
labeled (with red flags and lath) various locations in the
Fire Station Parking lot which correspond with these foot-
candle values at about 8:00 - 10:00 p.m. at night.
Councilmembers should take the opportunity before the
meeting to view these lighting intensities. The only value
missing is 4.3 foot-candles. However, a 4.1 foot-candle
reading was achieved and is identified near the front door
of the fire station.

The difference between a lighting intensity of 35 and 40
foot-candles is about 11%, as is the difference between 23
and 26 foot-candles. Using Musco lighting, provides
greater uniformity of lighting throughout the field and
fewer "light and dark spots" than the Hubbell proposal
based upon Musco and Hubbell data provided to our
consultants.
3)Musco Lil!htin!! Prooosal provides for the least !!lare:
Because the Musco system utilizes shields and reflectors,
including a lamp-tip cone, glare is reduced. According to
Wunderlich-Malec, the Hubbell system has no such
reflectors or shielding.
4)Musco Li!!htinl! Prooosal ~s up!!radable without usm!!
custom products:
Based upon the testimony of a Hubbell representative,
Hubbell light fixtures are not upgradable without
customization. With Musco lights, on the other hand, a
second level of shielding is a standard option that is not a
specially customized product.
5)Musco Lil!htinl! Proposal facilitates ease of maintenance.
According to Wunderlich-Malec, the Musco system
facilitates ease in maintenance because of its modularity.
The staff has had the opportunity to review the draft
minutes of the September 2, 1997 meeting. Shown below
are several of the arguments which were made by Hubbell
representatives and responses to each:
1) The City biddinl! process does not conform to Minnesota
Statutes 471.35.
The City Attorney, during the course of the September 2
meeting, read an excerpt from a Supreme Court case Otter
Tail Power Company versus the Village of Elbow Lake
which exempts this bidding from the provisions of
Minnesota Statute 471.35. The ruling reads in part that
the statute: "does not apply to contracts for work or
services or to contracts for the purchase of supplies or
equipment which include also the furnishing of work and
labor to effectuate the installation thereof."
2) The specifications were drawn too narrowly and ril!idly.
The specifications were performance specifications. The
consultant had verifiable data that the standards set forth
in the specifications could be met by Musco but not by
Hubbell. Hubbell, in their testimony at the September 2nd
meeting, claimed that they could have met the
specifications if they had had more time to prepare their
bids.
Hubbell acknowledges in their testimony that qualification
of their product was possible, and they do not object to
specifications referring to "Musco or Equivalent". In short,
Hubbell representatives by their own testimony confirm
that they were not eliminated from competition
The consulting engineers selected and specified the Musco
lights after the City Staff and Parks Advisory Committee
communicated to the engineer that the highest priority
was to 1) Provide minimum spillage and glare, 2)Provide
high quality athletic field lighting, and 3) Allow for future
upgrading of the lighting system to reduce spillage and
glare if necessary. The City Council should be able to
determine the level of protection it desires to provide its
residents and its athletes.
3) Hubbell had insufficient time to prepare their bid m
response to specifications.
Hubbell representatives at the meeting confirmed that
they were aware of the initial bid on June 10. In fact the
City Attorney advised Hubbell's attorney in a June letter
that the City intended to rebid the project. They had
notice for two months before the rebid was due on
91597.DOC
September 4. The argument that they had insufficient
time to prepare a bid is specious.
4) Because the specifications were so ril!id, Prior Lake
residents were deprived of the benefits of competition.
Musco is modular in design, and so according to the
consultants it is easier to install and therefore even
though the Musco lights may be more costly than the
Hubbell lights, often the successful bidders use Musco
lights as part of their bid. The Hubbell equipment, while
less expensive per unit, because of the lack of modularity,
is generally more labor intensive and installation costs are
higher.
The contractor is typically the first one to call if a
specification is non-competitive. Neither Wunderlich-
Malec or the City have received any calls from any
contractors that there was inadequate opportunity for
competition. Moreover, there were six bids and none of the
bidders complained about not being able to bid the
Hubbell lights.
According to information received by Park and Recreation
Director Hokeness, the bids received are comparable to
other bids submitted by both vendors when Hubbell and
Musco products have gone "head to head" (some examples
are shown in Park and Recreation Director Hokeness'
memo).
6) Wunderlich-Malec, the City's consultinl! en!!ineer, has
recommended Musco products in previous bid awards.
This creates the appearance of collusion.
Hubbell had the opportunity to pre qualify, and indeed has
stated on the record that they could have qualified. It is
the consultants position that the Musco product is
generally specified because it outperforms most other
products, due to modular design, glare control, spillage
. control, lighting intensity on field, maintenance, and cost.
7)The difference in product spillover is imperceptible to the
human eye. Moreover, the area of spillal!e is in a I!rove of
trees and does not reach the yards.
The data set forth early in this report refutes this
contention. In fact, there is a 40% - 70% difference in the
lighting intensity proposed, measured on the property of
91597,DOC
Prior Lake residents who will be affected by the lighting
for the next twenty years.
For the reasons set forth above, the City staff continues to
be of the opinion that the consultants specifying the Musco
system or equivalent has merit and is justified by the
unique circumstances of the Ponds Park proposal and
criteria communicated to the consultant by the City.
ISSUES:
The bid provided by Electric Service Company of
Minneapolis, Inc. is the lowest responsible bid. The bid
conforms to the specifications and provides a product
which the City can maintain, athletic field users will be
safe in using, and residents will be protected and should
be awarded the bid.
ALTERNATIVES:
The Council has the following alternatives:
1. Award to Electric Service Company of Minneapolis,
Inc. by Approving Resolution 97 -XX.
2. Reject all bids and authorize rebidding.
3. Defer action for a specific reason.
RECOMMENDATION: On the basis of expert information provided by the City's
Consulting Engineer, Wunderlich-Malec, the staff
recommends that the City Council approve Alternative #1.
FISCAL IMPACT: The bid price is within the limits contemplated within the
referendum budget.
ACTION REQUIRED: Motion and second to approve resolution 97-XX.
Wunderlich-Malec representatives will be present at the
City Council meeting if any clarifications are desired by
Councilmembers.

Dear Paul,
I am writing in regard to the information provided at the council meeting by Richard Feig on
behalf of Hubbell Lighting and R.L. Mlazgar Associates. Mr. Feig was portrayed to be an
independent electrical consultant which is not exactly accurate. Mr. Feig and the Hubbell
representative, Ray Mlazgar, have had a close relationship over the past 30 years. Most all of the
athletic field lighting projects, designed by Mr. Feig, have resulted with Mlazgar and Hubbell
Lighting getting the project. However, over the past 4 - 5 years, I am not aware of Mr. Feig
designing any athletic field lighting. This provides additional questions as there has been many
advancements in athletic field lighting just within the past 3 years.
At the meeting, Dick Feig told the Council that he had specified Musco Sports-Lighting as far back
as the mid 1960s. I found this unusual as Musco Sports-Lighting was established in 1978. Mr.
Feig also stated he had done design of controls for spill and glare light. He did not mention that
this work was done for Hubbell lighting and that the spill and glare light control he designed is
what is found on the Hubbell lights at Dred Scott Field in Bloomington. I believe the only reason
Mr. Feig was at the meeting was because of his close relationship with Ray Mlazgar.
My intent is not to discredit anyone but to portray things in an accurate manner. Control of spill
and glare light is a very important part of this project. Musco Sports-Lighting has the ability to
control unwanted spill and glare light. The specifications require control of this light to prevent
the ball field lighting from being an annoyance to the neighbors. Hubbell lighting has little control
of glare light and had trouble meeting the moderate spill light control required by the specification.
There has been no collusion in the design of the specifications as inferred by Hubbell's attorney.
The specifications are based on performance standards which will provide the City with correct
field lighting for safe play and elimination of unwanted spill and glare light from neighboring park
property .
It should also be noted that while Musco Sports-Lighting met both field lighting requirements and
spill control requirements, Hubbell Lighting failed on both requirements. Not only did Hubbell
fail to cut adequate amounts of unwanted spill light, they also failed to provide the required
amount of field lighting.

WME Project #4406
Dear Paul:
This letter serves to address var ious issues presented by
R.L. Malasgar and Associates (RLM) at the Prior Lake City
Council meeting on September 3, 1997. In particular, I
would like to comment on the performance-based nature of our
specification, the fairness with which we have treated RLM,
and the allegation of "collusion" which was raised by their
representatives.
While we would have been quite content to discuss the merits
of our design, which we believe to be the best possible
solution to the engineering task presented to us, I cannot
let certain assertions go unanswered.
Concerning the performance-based structure of our
specification, we feel that Musco has an extensive track
record which establishes their typical lighting systems,
distribution, and glare and spill control as a reasonable
benchmark for performance. We further believe that the base
specified performance intent is attainable by most
manufacturers under most conditions and that the process for
approval is very clear. On this basis, our specification
establishes a reasonable opportunity for competitive
bidding.
On the issue of overall fairness to this vendor, I would
like to make it clear that we have afforded RLM
extraordinary opportunities to demonstrate their ability to
effectively comply with our specification.
Our dealings with them have included lengthy and detailed
discussions concerning product characteristics and
performance. We have generally felt that the Hubbell
product is viable for many applications, but that submittals
by RLM have routinely been flawed. In fact, they have been
quite contentious in nature, exhibiting an "I know what is
best for you" attitude. They have submitted materials that
they have known to be expressly contrary to the preferences
of us and our clients, even when suitable alternatives are
readily available. In particular, they have insisted that
Cor-Ten finish poles and integral fixture ballasting should,
in their opinion, be routinely accepted by us. We certainly
do not agree.
On this project, we actively solicited a bid from Hubbell.
Solely at our request (not Hubbell's), a meeting was
conducted at our office where we walked them through the
specification and explained our position on each issue. In
some cases we offered clarifications which we feel were
beneficial to Hubbell. We also made certain concessions
regarding the requirement for computer-generated printouts,
where we offered to manually calculate certain areas.
In their final submittal, RLM could still not even nearly
meet the specified performance for spill light, a major
criterion for the project. As we illustrated in the graphic
presented to the Council, the numbers aren't even close.
Since they have subsequently stated that they can meet the
specification, the contention that we are not being fair is
without merit. We also find their comments regarding the
available time frame to be groundless.
Most importantly, I must comment on the RLM allegation of
"collusion". This is a serious matter that should not be
taken lightly. We certainly do not, nor should you, as such
allegations reflect directly on our respective reputations.
Our position in this matter is a follows:
1. We have, over the course of many years, developed
appreciation for the Musco product and maintain a
cordial, wholly professional relationship with their
representative. This relationship is a directly
attributable to their usual excellent performance,
exhibited at all levels of a project. Such performance
is precisely what we wish to deliver to our clients.
We have similar relationships with many of the quality
vendors in this area.
2. We overtly specify the Musco product performance
criteria. As I have previously stated, these criteria
are intended to be attainable by other manufacturers.
That our specification is attainable has now been
validated by Hubbell. We encourage, accept, and
evaluate submittals for alternate products. In all
cases, our clients are kept fully aware of our
activities. By definition, this could hardly be called
collusion.
3. As a firm, we have an obligation to promote competition
and do so at every opportunity. We do not have an
obligation to artificially create competition by
accepting substandard systems or products, nor do we
control the cost competitiveness of alternate products.
Upon review of our past projects it is evident that Musco
has, in fact, been the successful supplier for all or nearly
all of our recent sports lighting projects. From our
viewpoint, this is true by circumstance rather than intent.
Our records indicate that we have actively solicited
submittals from other vendors such as GE and Hi-Tek, but
they have had little interest in these projects. From our
discussions with these suppliers and bidding contractors,
the Musco specification has influenced their interest in a
negative way only to the extent that they do not feel they
can be competitive from an installed cost standpoint. They
typically have stated that the performance aspects are
"tough" but "attainable". This stated, it is certainly
plausible in our opinion that Musco has simply found a
market niche of performance versus cost that is hard to
beat. If so, the ultimate winner is the end user.
We flatly reject allegations of "correlation" or
"collusion" . Our actions have always been in the best
interest of our clients, honorable and entirely without
complicity. They will withstand any scrutiny. I am
prepared to offer letters from other major vendors which
endorse our specification and approval policies. However,
in my 20 plus years in this industry, nobody has made such
ridiculous claims. It troubles me that such endorsements
might be necessary and I would prefer not to take this
course.
We regret that the City has become so involved in this
dispute. Obviously, the easy solution would be to
compromlse, but compromises such as these so often end in
poor results. I believe the principles of this dispute are
worthy of this effort.

PAUL HOKENESS, PARKS & RECREATION DIRECTOR
CONSIDER APPROVAL OF RESOLUTION 97-XX AWARDING
BID FOR ATHLETIC FIELD AND SECURITY LIGHTING AT
POND'S PARK
SEPTEMBER 2, 1997
DATE:
INTRODUCTION:
One of the items which was included in the 1997 Parks and Library
Bond Referendum was the installation of athletic field lighting at the
Pond's Park (Mangan Fields). The purpose of this agenda item is to
award the bid for installation of the athletic field lighting. Field
lighting at the Pond's has been requested by P.L.A.Y. and adult softball
for many years. The referendum gave us the opportunity to address this
request and was a major selling point in the referendum.
BACKGROUND:
At the April 7, 1997 Council Meeting, the Council approved
proceeding with the bidding of the Pond's lights. The City retained
Wunderlich-Malec as electrical engineering consultants to prepare
plans and specifications. The specifications were prepared with the
understanding that the amount of light spilling onto neighbors yards
had to be kept to a minimum. The project was advertised with a bid
opening date of June 24, 1997. After only receiving two bids with the
lowest being $332,000.00 and the highest at $417,388.00 the electrical
engineering consultant suggested that the City Council may want to
consider rejecting all bids and rebid the project with the hopes of
attracting more contractors and reducing the costs by having a fall
installation. At the July 21, 1997 meeting Council concurred with the
recommendation of the electrical engineer, approved the rejection of
bids and authorized the rebidding of the project. The project was rebid
and bids were opened on August 26, 1997 at 10:00 a.m.. Wunderlich-
Malec has tabulated the bids and recommends that the City approve
Electric Service Company of Minneapolis, Inc. as the responsible low
bidder in the amount of $310,408.00. The rebidding of this project
resulted in a savings of $21,592.00.
Staff is pleased with the results of rebidding this project. We were able
to come in under the original estimates, Electric Service Co. of
Minneapolis is very reputable firm with field lighting experience, and
the City will have a lighting system that will meet our needs and have
minimal impact on our park neighbors.

AN EQUAL OPPORTUNITY EMPLOYER
DISCUSSION:
When the Parks Advisory Committee conducted it's neighborhood
meeting with the residents adjacent to the park one of the concerns
raised was a lack of security lighting in the park. The P.A.c. and staff
felt that this would be worth pursuing at this time so that security
lighting could be included in the bid. It would make sense to add this
lighting at this time as we would save money by using the same
trenching, conduits, and poles. For this reason the project was bid with
an alternate for security lighting. There have been virtually no
complaints from the neighbors concerning the installation of lights at
the Pond's. The commitment that was made to the neighbors was that
the field lights would be designed so that the light is directed onto the
fields and would do everything possible to minimize the amount of
light that would spill into their yards, and into the sky. The Parks
Advisory Committee also told the neighbors that we would consider
additional security lighting and include this as a bid alternate.
The following table shows the bid tabulations for the project:
Vendor Bid Alt. Total
Electric Service Co. 5301,108.00 $ 9,300.00 S310A08.00
Klein Electric, Inc. S309,800.00 $ 9,190.00 $318.990.00
Jay Bros. Inc. $317,447.00 $14,605.00 $332,052.00
Electrical Installation
& Maint. Co. $325,000.00 $21,000.00 $346,000.00
Arcade Electric Co. S343,877 .00 $15,120.00 $358,997,00
Ridgedale Electric, Inc. $342,000.00 $20,000.00 $362.000.00
ISSUES:
Staff wanted to achieve two objectives when it requested that the
council reject all bids and authorize rebidding. The first objective was
to encourage greater competition. This objective was achieved in that
six contractors bid this project as opposed to the two bids originally
received. The second objective was to save money. Because of the
additional competition and the time of year the low bid is $21,592.00
less than the previous bids.
We received the attached letter from the attorney who represents R.L.
Mlazgar Associates Inc. (R.L.M.), a firm which supplies athletic field
lighting. The letter protests the fact that RLM was unable to supply
materials for this project because their lights exceed the spill light and
glare specifications which were identified in our specifications.
R.L.M. was given every opportunity to prequalify, however, they failed
to meet the specifications.
AGPNDLlTDOC
The attorneys letter also implies that the addendum which was sent out
specifies that Musco is the only product that would be considered.
This addendum was sent out to the contractors only after RL.M. failed
to prequalify for the project Prequalification is a common practice and
when a supplier of a product meets specifications the engineer sends
out an addendum to the contractors who are bidding on the project to
let them know what materials to use when preparing their bids. In this
case RL.M. failed to meet the specifications and the engineer sent out
the addendum to let the contractors know that they should use Musco
light fixtures and poles, and Sternberg fixtures for security lighting.
RL.M. did meet the specifications for the security lighting and would
be able to provide these fixtures if they so desired.
The specifications were designed to protect the adjacent homeowners
from light spilling onto their yards, as well as into the sky. At the May
12, 1997 neighborhood meeting the Parks Advisory Committee made a
commitment to do just that. (Attached is the neighborhood meeting
announcement and the map which shows the mailing area.)
The other concern when preparing specifications was to make sure that
we are directing as much light as possible onto the fields and reducing
the amount of glare that the players look into. This factor improves
play and player safety.
R.L.M. cannot provide the protection our residents should have and
consequently were not approved as an acceptable product supplier.
Attached is a letter dated August 19, 1997 form the City's lighting
engineer which elaborates upon this fact. Representatives from
Wunderlich-Malec Engineering, Inc. will be present at the Council
meeting to answer any questions that the Council may have regarding
this project.
Staff and the lighting engineer believe that the specification were
designed to meet the City's objectives of protecting its residents and
athletes and as such are appropriate and defensible. The City Attorney
has verified that the City appropriately followed the applicable bidding
statutes.
If the City Council approves the low bid and this contract is let, a
Musco lighting system will be installed in The Pond's park. With a
Musco lighting system it is possible that in the future we could install
additional shields on the lights which would provide even greater spill
light and glare control. We chose not to specify a total light control
system at this time due to budget limitations.
The option to further reduce light spill and glare is not available with
the Hubbell system. The best spill and glare control that the Hubbell

system can offer is what they have already proposed, and that was not
able to meet the specifications.
By rebidding this project we were not able to provide lights for fall
football this year and P .L.A. Y. was disappointed, but they understood
our rationale for rebidding. If this project is delayed again we will not
be able to provide lights for spring baseball, softball, and soccer and we
believe that the disappointment may turn to anger. With our current
shortage of athletic fields the addition of lights at Pond's Park will
relieve some of the pressure until our new fields can be constructed.
The low bid came in lower than our original estimates which were
$300,000.00 for field lighting and $20,000.00 for security lighting,
Funding for this project is included in the 1997 Parks and Library
Referendum.
The alternatives are as follows:
1. Adopt Resolution 97-XX awarding the bid for field and
security lights at the Pond's Park in the amount of
$310,408.00 to Electric Service Company of Minneapolis
Inc.
2. Deny this item for a specific reason

Bids were received this morning at 10:00 a.m. from six of the
nine plan holders. Base bids were within 17% ($51,592.00) of
each other, low to high. Please refer to the bid tabulation.
The apparent low bidder is Electric Service Company of
Minneapolis, at $310,408.00, base bid. WME has had considerable
experience with this contractor and considers them one of the
best in the Twin Cities Area. As a matter of fact, WME has
provided the engineering for three other ball fields currently
under construction in the metro area, all of which are being

Re: Pond Athletic Complex
Site Lighting
WME Project #4406
Dear Paul:
As you may know, our firm has been going to great lengths to
accommodate the Hubbell product in the rebid of this
project.
In response to concerns that have been expressed by their
local representatives, we have made several specification
revisions and have been quite aggressive in soliciting a
viable submittal.
Largely at our request, the local representative as well as
a Hubbell National Accounts Manager and the local Miller-
bernd (pole) representative hand-delivered their submittal
to us on August 14,. We discussed our design positions at
that time and came to agreement on several specific key
points relating to product quality and performance.
The meeting adjourned with an understanding that we could
generally accept the products as submitted (with noted minor
exceptions) on the condition that, under our subsequent
closer evaluation, the lighting performance would be
comparable to that specified. In our closer evaluation,
however, we have found significant variations in their
submitted values, particularly in the area of average
illumination and spill light.
Unfortunately, even though we have made every effort to
cooperate with the Hubbell people, we seem to be back to
square one. Despite the progress we have made, we are once
again faced with the difficult issue of recommending against
the submitted system.
Given the attitude and past actions of this vendor, we would
certainly understand if you might still prefer to accept a
bid from them. We will proceed with any recommendation you
may offer.
Please let me or Jim O'Brien know of any comments you may
have. Again, thank you for your patience in this matter.

Dear Wally.
It sounds to me as if you have given Hubbell and Millerbernd every opportunity to pre-qualify
for this project. As a matter of fact you have gone out of your \oval' to assist them in their efforts
to provide poles and lighting equipment for this projec:.
The bottom line is if they do not meet specifications, especially in the area of field illumination
and spill lighting, then we should not be accepting their product. Kno\oving the sensitivity of a
field lighting project in a neighborhood with residents less than 100 feet from our fields it is
imperative that the lighting manufacturers meet the specifications that you have set forth.
The City of Prior Lake has hired you to make a recommendation regarding the lighting of the
Pond's Athletic fields and \ove support your recommendations.

Re: City of Prior Lake Ponds Park Athletic Field Lighting Project
Dear Ms. Pace:
Recent events in the ongoing efforts of the City of Prior Lake to acquire lighting
for the Ponds Park Athletic Field require that I again correspond with you on this
subject.
To satisfy your previously-expressed curiosity, our client is R. L. Mlazgar
Associates, Inc., a family-owned company which 'n the business of supplying
lighting for projects such as this for over 25 year RLM Id provide ve satisf
lighting materials for the Ponds Park project and ~ m eSlres an 0 ortuni to
jOI In the competition for this work. However, despite extensive effort to receive
consideration, including the expenditure of over $1,000.00 in independent engineering
services, RLM again has been frozen out of this project by action of the engineering
firm managing the project for the city. Enclosed with this letter is the final word on this
~subject from that firm, Wunderlich-Malec Engineering. This "addendum" to the lighting
specifications discloses that bids from electrical contractors on this project will not be
considered if they include materials from any manufacturer other than the MUSCO
Sports Lighting Company of Muscatine, Iowa, except for a small portion of the job for
which MUSCO does not carry the necessary item.
RLM was advised by Wunderlich-Malec that its products were rejected from
consideration because they exceeded the "spill light" and "glare" specifications
prescribed by the engineer. RLM has advised me that the only products known to it
which can meet those specifications are those of MUSCO, That fact alone should be
very troubling to anyone favoring competition in public procurement. Even more
LT01:433581_1
..
LINDQUIST & VENNUM P.LLP.
August 25, 1997
Page 2
troubling is the apparent fact that the amount by which the RLM products exceed the
specifications for "spill light" and "glare" may be undiscernible to the human eye. In
other words, competition for lighting materials has been eliminated for the sake of
specifications which are of no practical benefit to the citizens of Prior Lake.
The refusal of Wunderlich-Malec to approve the RLM product for bid
consideration was simply the final act in a course of hostile treatment accorded to RLM
during its efforts to receive consideration for its products. RLM's aggressive pursuit of
an opportunity to compete has been quite unwelcome, as we fear our bringing this
matter to your attention may also be unwelcome. The easy course, and the common
course for materials suppliers in these situations, is to do everything possible to curry
favor with the engineering firm responsible for issuing specifications. Challenging the
engineer may jeopardize the supplier's fortunes not just on the instant job, but on future
jobs as well. RLM consciously runs this risk in its current effort to provide the citizens
of Prior Lake with the benefit of competition. I encourage you and the public officials
whom you represent to be mindful of this fact as you evaluate this situation.
As you know, Minn. Stat. 8471.35 requires that materials specifications for
public bids "shall not be so prepared as to exclude all but one type or kind but shall
include competitive supplies and equipment." It is our firm belief that the current
specifications for the Ponds Park lighting project violate that statutory requirement.
Testimony supporting this contention will be offered at the upcoming meeting of the city
council in opposition to any contract award based upon the existing specifications. I
urge you and the other city officials to give that evidence careful consideration before
proceeding with the award of the contract.
Very truly yours,
Thomas L. Fabel

RE:
Ponds Athletic Complex
WME Project No. 4406
Specification Article 16010 1.6.D mandates submittals for prior
approval be submitted ten days prior to bid date, that would make
Friday, August 15, 1997 the final working day prior to the cutoff
date. Hubbell made their submittal for prior approval On August
IS, 1997 at 11:00 a.m. This submittal did not include structura:
calculations for poles and bases due to the explanation that the
engineer for Millerbern Pole Company was on vacation. They
stated in the submittal that they would provide these
calculations "on or after August 18, 1997, but prior to bidu.
They were submitted on August 22, 1997, five days after the
deadline for submittal. The Hubbell submittal showed light scans
on ~he softball field ~o 26U' and the fence is at 275'. They had
Pole C3 in the wrong location as well. They were requested to
correct these two items. They could not complete the correction
on August 15, 1997, so WME allowed them to submit prior to noon
on August 18, 1997, re-submittal was made at 9:40 a.m. on August
18, 1997.
All calculations are to be based on a lamp with 155,000 lumens
(standard 1500 watt metal halide lamp) per Specification Article
16500 2.4.A.2 and 16500 2.5.A.2. Hubbell's submittals are based
on 150,000 lumens for the softball initial foot-candles. This
lumen level will consequently skew their spill lighting levels
lower. This is represented on Hubbell's drawing #97-1262FR.
Hubbell's calculations for the softball "maintained foot-candlesu
should be based on the specified 155,000 lumens with a specified
0.8 maintenance factor, calculations submitted on drawing
#97-1262ER use 166,500 lumens with a 0.8 maintenance factor.
This skews the numbers higher. WME pointed out the areas where
they did no~ comply with the specifications. It was agreed by
Hubbell representatives and WME that WME would interpolate the
numbers to arrive at the correct foot-candle levels.
...
\
MEMORANDOM
Mr. Paul Hokeness
Augusc 19, 1997

WME recalculated the softball maintained foot-candle levels and
arrived at 29.0 infield and 19.6 outfield. Specifications call
for 31 intield and 21 outfield. Hubbell does not meet
specifications on this point.
WME did a straight number-to-number review of the spill lighting
for the softball fields even though Hubbell used a lower than
specified lumen level. Foot-candle levels horizontally and in
maximum plane will be higher than indicated on their drawing
#97-1262FR. Specifications call for a maximum horizontal foot-
candles of 0.15, Hubbell's calculations indicated 0.4 (a 160%
variation). The maximum foot-candles in maximum plane is
specified at 0.92, Hubbell's calculation indicates 1.6 (a 74%
variation.
On the softball fields Hubbell submitted a lighting system which
would require more fixtures on some poles and less on other poles
than was specified on the plans. This will require more
engineering time to recalculate the circuit breaker, conduit, and
wire size for each of these twelve poles. We would then have to
reissue these updated draWings to the electrical contractor.
This will take several hou~s of engineering time as well as
expenses associated with reissuing the drawings. Our fee does
not include additional services for redesign due to vendor
modifications.
The football fields a~e calculated with the higher 166,550 lumens
per lamp. When adjusted, the average maintained foot-candle
level per field is 24.2, specifications require 26 (a 7.4%
variation) .
The football spill lighting maximum plane maximum specified foot-
candles is 3.07, Hubbell's adjusted level is 4.0 (a 32%
variation). The maximum initial horizontal foot-candles
specified is 1.02, Hubbell's adjusted level is 1.76 (a 73%
variation) .
Ln all cases the lighting calculations for the Hubbell equipment
proves that the amount of spill lighting directed onto the
neighbors properties exceeds the specification~. This is not a
minor difference as suggested by the Hubbell representative, but
in most cases there are major variations from the specifications,
as noted above. We realize that one of the major concerns is the
amount of spill lighting on the neighbor's property, but please
note that Hubbell did not meet specifications for the amount of
light needed on infields and outfields of the softball fields.
