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 i\Ieeting, 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 Minneapol\s. Inc. as the responsible lo\v
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 ofrebidding this project. We were able
to come in under the original estimates, Electric Service Co. of
Minneapolis is very reputable firm \Vith field lighting experience. and
the City will have a lighting system that will meet our needs and have
minimal impact on our park neighbors.

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.e. 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. $301,108.00 $ 9,300.00 $310,408.00
Klein Electric, Inc. $309,800.00 $ 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. $343,877.00 $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 tirm 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.
AGPNDLIT.DOC
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 R.L.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 R.L.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.
R.L.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.

AGPNDLIT.DOC
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
3. Table this item for a specific reason.
Staff recommends Alternative No.1.
Motion and second to approve Resolution 97-XX accepting the bid of

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
installed by Electric Service Company.
Based on the bid furnished and Electric Service Company's
experience with the specified products, I would recommend award
of contract to them.

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 way to assist them in their efforts
to provide poles and lighting equipment for this project.
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. Knowing 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 we 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 has been in the business of supplying
lighting for projects such as this for over 25 years. RLM could provide very satisfactory
lighting materials for the Ponds Park project and very much desires an opportunity to
join 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
LTOl: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 "spilllight" 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. S 471.35 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

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
15, 1997 at 11:00 a.m. This submittal did not include structural
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 bid".
They were submitted on August 22, 1997, five days after the
deadline for submittal. The Hubbell submittal showed light scans
on the 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-candles"
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.

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 hours 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 are calculated with the higher 166,550 lumens
per lamp. When adjusted, the average maintained foot-candl~
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) .
In 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.
