Date of Assessment: June 28,2017
Date of Revised February 25,2018
Proposal:
RLA Conservation is pleased to submit the following proposal for conservation and maintenance of
two artworks—one si*-specific bridge mosaic installation and one bronze sculpture-4n the
permanent public art collection of the City of Fort Worth. The pieces were examined June 27,
2017, by chief conservator Rosa Lowinger, in conjunction with City Public Art Manager Jenny
Conn. The purpose of the assessment was to come up with recommendations for maintenance
and/or conservation and provide general cost/time recommendations for the work.
Based on the assessment,we anticipate that the treatment of Prarie W»d,as well as sounding&
the collection at Embroidery Dreams will take place over the course of a one week trip. Any
replacement tessera needed will be notated, researched and installed during a subsequent visit
(TBD). After the first visit, we will be able to provide a better estimate for the treatment of
Emlxoidery Dreams.This will also give us time to determine the logistical needs for these mosaics.

1. ARTIST:MICHAEL PAVLOSKY
TITLE:PRAIRIE WINO
Date:2010
Location:HadleyPark
Materials:Bronze
Dimensions:Not available at this time
Description:This is a single component bronze monument with a figure on top.The piece sits in
the center of a circular double concrete platform with expansion joints and water run off points cut
into the concrete. The sculpture itself is a hollow cast bronze column,pyramidal in profile, with
embossed figures of woodland animal:K, birds, and sea creatures respectively on each face. The
animals are heavily articulated with raised and incised lines to create the shapes. The relief is
approximately V in depth at the highest point.The sculptural figure on top is a female in a long
flowing dress with amts up stretched over her head and her left arm extending to the left. She
arches backwards and her hair flows to the left. The surface color is a mottled golden-brown
patina.The patina has been worked on in the past and there are areas of golden color with depth,
surrounded by areas that appear to have been abraded off and not fully integrated.
Condition:Overall the piece is intact structurally,with no apparent breaks,cracks,or losses.This
was examined from ground level and the figure itself should be checked for stability. The main
concern with this artwork is extensive and pervasive bird droppings and patina alteration. The
piece is the only tall item in the landscape in this area for approximately 40'.Therefore,birds roost
on the top and have covered the top and sides in droppings.The most badly affected side is the
one that has the fish on it.The hands of the figures,especially the proper right hand,are especially
thick with droppings. One assumes that the top of the pyramidal column is also covered but it
cannot be seen from ground level. This artwork suffers greatly from this condition. A previous
conservation treatment to remove the droppings resulted in damage to the patina. According to
Jenny Conn, this was addressed by partial or full re-patination. The color, however, remains
uneven especially on the column, and especially on the face with the birds that looks to the
Southwest.There are patches of mottling and color shifts that do not look appropriate.Overall the
figure is darker than the column.The base has striations as if it had been cleaned harshly with an
abrasive pad leaving silvery patches of metal.

Recommended Conservation:
NOTE:There is no water at this site and the cost for bringing in a tank of water is not caiculatea
within these estimates.
1. Test mock-ups of color off site at RLA studio prior to arrival in Ft.Worth to hone in on
proper patina formulation.Alternatively,obtain proper patina formula from artist's studio.
2. Dry brush bird droppings using proper face protection.
3. Rinse the sculpture with filtered tap water. Wash with a conservation grade detergent and
filtered tap water to remove dirt and grime.
4. Remove corrosion mechanically with mild abrasive pads.
S. Clean with organic solvents as needed to remove oily residues and old wax in preparation
for local re-patination.
6. Re-patinate areas of patina loss to blend with desired effect.
7. Apply an RLA formulated conservation grade wax to heated metal. RLA proposes using a
high-milting temperature formula.
8. Apply one coat of cold proprietary paste wax to the surface.Buff in early morning or in
conditions that will not remove the wax.
9. Prepare a detail report describing the materials and methods used for treatment and
maintenance recommendations.

TITLE:EMBROIDERY DREAMS -�
Date:2012
Location:28'St.Bridge
Materials:Glass and ceramic tiles
Dimensions:Not available at this time
t
Description: This artwork is a major architectural feature consisting of an entire bridge that was
fabricated to include cast concrete panels and mosaic panels.There are four sides to the artwork.
Two of the sides face the roadway,and two of the other skies face a riverbed.
The decorative cast concrete is all on the river— facing portions. These consists of high relief
concrete forms and figures, primarily in decorative recognizable forms. The main subject of this
report are the mosaic panels.There appeared to he 58 panels in varying lengths.All are the same
height which is ca.4'.
On the river facing portions there are also long thin vertical mosaic elements that go from the base
of the bridge down to the level of the water. The images are of doves flying with outstretched
wings, flower garlands, and peacocks. The most common of the panels depict the outstretched
winged doves.34 of the parcels represent this image.There are 16 flower garland parcels and eight
Peacock panels. The Peacock panels are larger than the other ones. There are also round inset
mosaic parcels in the bridge deck These appear to be exhibiting excessive damage. There is
wholesale detachment of the tesserae and they are not well bonded to the surface.
Condition: Most of the mosaics are in good condition. The colors appear stable and the grout
appears stable. There are two main types of damage. One is large areas of tessera loss due
primarily to impact of some son.There are two main areas of the bridge that exhibit this condition
—both on the south side.The second area of damage is more perplexing,and that is widespread
detachment of individual tesserae. Almost every panel exhibits some variety of this condition.
From a quick observation it appears that the panels with the blue doves have the condition the
worst.It is not clear what is causing this;however,there is excessive vibration on this bridge and
it's possible that constant movement is jostling the tesserae off of the mortar and grout beds. At
least three of the long vertical panels on the interiors exhibit large areas of loss as well. The area
around this artwork is very dirty and there is a great deal of broken glass and debris mixed in with
detached tesserae on the bridge deck.

Recommended Conservation:
NOTE: This treatment should be performed in stages. Phase 1 consists of steps 1-5 and will be
completed during the initial,one week site visit and assessment.Treatment of the mosaics would
occur at a later date TBD.It is possible that due to heavy traffic,the work would be best performed
at night If so,cost for labor would rise 15-20%and additional safety equipment and lighting
would be required.
1. Perform a full sounding of the panels to determine how much detachment is present.
Sounding of the river-side portions can only be achieved if there is major debris removal in
that area and protections are put in place for work to be carried out. We recommend
beginning on the bridge decks themselves.
2. Examine the materials used to set the dies and see if something that has a bit more
elastomeric quality can be used to prevent popping from vibration.Test the condition of
the adhesive and work with the manufacturer who provided the adhesive.
3. Gather the loose tesserae on a regular basis and save them for reattachment.
4. Source replacement tiles for future treatments.Provide samples of replacement tiles for
approval.
S. Determine if a different adhesive needs to be used.
6. Repair floor mosaics.•
7. Mobilize a full conservation program for the bridge,with the possibility of resetting large
swaths of tile as needed.
B. Clean all loose rises and all areas to be worked on.
9. Adhere loose tiles in place.
10.Inject areas that are detached but not lost.
11.Perform the same on the river-side portions(costs are not included for this as they will
need to be determined in phase 1.)
12.Grout areas where tiles are replaced.
13.Prepare a detail report describing the materials and methods used for treatment and
maintenance recommendations.
'Consider relocation of floor mosaics.
