ROSEMEAD CITY COUNCIL
STAFF REPORT
TO: THE HONORABLE MAYOR AND CITY COUN IL
FROM: ANDREW C. LAZZARETTO, CITY MANAGE
DATE: AUGUST 22, 2006
SUBJECT: ACCEPTANCE OF ROSEMEAD PUBLIC SAFETY CENTER PROJECT
SUMMARY
Construction of the Rosemead Public Safety Center has been completed in
conformance with the approved plans and specifications.
Staff Recommendation
Staff recommends the City Council take the following action: (1) Accept the completed
construction work; (2) Authorize the City Clerk to record the Notice of Completion for the
project; and (3) Authorize the release of the retention payment 35 days after recording
the Notice of Completion.
ANALYSIS
In August 2005, the City Council awarded the bid for this project to Abeam Construction
Company in the amount of $609,000. Total amount to be paid to the contractor including
change orders and the retention payment is $746,017.13. Since this amount is
significantly above the contract, staff directed the architect to summarize the change
orders, which include the following:
Mold Remediation
Once portions of the interior were demolished, substantial mold was uncovered. The
total cost for the inspection, repairs and certification totaled $85,390.88. Copies of the
Mold Assessment Report and Post Mold Remediation Evaluation Report are attached.
Unforeseen Site Conditions
The total cost to correct these conditions was $20,827.18. The Fire Department
required an additional $9,188.04 for fire alarm work which also required additional
drywall repair in the amount of $2,029.86. The remaining items included repair to the
concrete, flooring and a leaking water heater.

Owner Requested
The City decided to upgrade the CCTV system by $7,596.60, install additional light
fixtures and electrical outlets, and revise the existing monument sign and some
additional cosmetic upgrades.
The building was originally constructed in 1984 and was operated as the Zapopan
Community Center until the Garvey Community Center opened in 2004. Subsequently
the building had remained closed except for Neighborhood Watch meetings. Staff and
the architect of record feel confident that the newly remodeled building will remain
serviceable for many years to come.
FINANCIAL REVIEW
This project was funded with CDBG funds, tax increment funds and an Office of
Criminal Justice and Planning grant, courtesy of Congresswoman Hilda Solis.

RE: Limited Preliminary Mold Assessment
Rosemead Public Safety Center

Rosemead, California 91770
EXCEL Project No., 05-001-01:751
Dear Mr. Santos:
1. PROJECT INTRODUCTION
The Excel Environmental Group, Inc. (EXCEL) conducted a limited preliminary mold
assessment in the general reception/office, foyer, kitchen, and deputy office of the above-
referenced property on Octobcr 25, 2005. The objective was to determine if water/moisture
damaged from a roofing failure resulted in mold amplification in the affected building
components.
II. PROCEDURES AND METHODOLOGY
The assessment consisted of a visual review of the known affected areas of the property; the
collection of indoor and outdoor baseline air samples; the collection of indoor particulate
samples; and moisture readings. The sampling locations, number, and type of samples taken
were determined based on the areas, building components, and extent of water-damage/suspect
mold amplification. The assessment and sampling was limited to the areas suspected of being
affected by the water/moisture damage and exposed building rnaterials/structural components.
111. LABORATORY ANALYSIS
Non-viable baseline and ambient air samples were collected using Zefon Air-O-Cell cassettes
and high volume air samplers. Non-viable particulate samples were collected using "tape-lifts"
or sterile swabs. All samples collected were delivered, under chain of custody, to Forensic
Analytical of Rancho Dominguez, California for identification and enumeration of mold spores.
Results of the analyses are presented in Attachment 1.

IV. FINDINGS
Elevated moisture levels were detected in the deputy office (north and west walls)
Visible suspect mold growth was observed in the general reception/offiec (south wall), foyer
(south and east walls), kitchen (wall-mount cabinets and wesVeast walls), and deputy office
(north and west walls). Representative particulate samples were taken.
Forensic Analytical reported major to abundant levels of hyphae, peniclliuWxpergillus, and
scopulariopsis mold in the particulate samples collected from deputy office (north wall) kitchen
(west wall) of the property (see Attachment 1).
Forensic Analytical reported that the total mold spore counts in the samples collected from
deputy office and foyertkitchen (center) were lower than the spore counts observed in the
outdoor baseline non-viable air sample; however stachybotiys was observed in both samples (sec
Attachment 1).
Please note that in addition to the types of spores identified above, multiple types of mold spores
were detected throughout the samples collected; and individual species were identified in
isolated samples in the affected area(s) of the property,
V. RECOMMENDATIONS
Based on the findings of this assessment, the following recommendations are made
A. Remove wallboard wall material (full height) in the
General Recepdon/Office (south wall)
Foyer (south, west, and cast walls)
Kitcben (north, west, and east walls)
Deputy Office (north and west walls)
Utility Room (south and east walls)
Note: Additional wall removal may be required training room (south wall
- opposite kitchen) and bathroom (north wall - opposite general
reception/office) - Please field verify.
Removal of wall material should be a minimum of two studs
beyond visible water damage/mold amplification.
13. Remove any cabinets, equipment, fixtures, and contents to facilitate the
removal of affected materials. Clean and treat any affected cabinets,
equipment, fixtures, and contents, once removed, with an anti-microbial agent

to minimize or prevent future microbial growth. (Note: Some cabinets,
equipment, fixtures, and contents may not be able to be removed without
damage. and some finishes cannot be sufficiently cleaned and treated).
C. Remove and dispose of remaining exposed ceiling insulation in the affected
areas. Thoroughly clean/scrub all exposed ceiling cavities utilizing an anti-
microbial agent and vacuums utilizing HEM filters. The objective of the
cleaning is to remove excess dust, moisture, and residual mold spores.
D. Remove and dispose of any existing wail insulation after removing wall
materials in the affected areas. Thoroughly clean/scrub all exposed wall
cavities utilizing an anti-microbial agent and vacuums utilizing HEPA Filters.
The objective of the cleaning is to remove excess dust, moisture, and residual
mold spores.
Note: Inaccessible areas with shear walls should be treated with an anti-
microbial agent utilizing access holes that do not affect the
structural integrity of the shear walls.
E. Conduct remediation activities in a negative pressure enclosure utilizing
HEPA filtration. The objective is to isolate the remediated area(s) to prevent
dispersion of mold spores to unaffected areas of the property. Avoid activating
any 14VAC systems during remediation activities.
F. Clean any affected HVAC ductwork, registers, returns, and plenums upon the
completion of remediation activities and prior to post remediation
confirmation sampling. Replace all affected HVAC filters. The objective of
the cleaning is to remove excess dust and residual mold spores,
G. Conduct all remediation activities utilizing worker protection: respirators
utilizing HEPA filtration, disposable body suits, eye protection (goggles),
hand protection (rubber gloves in conjunction with work gloves), and ear
protection (earplugs).
H. At the completion of remediation activities and prior to the installation of
replacement building components/finishes, post remediation confirmation
sampling should be conducted. Post remediation confirmation sampling
should include the collection of tape-lift samples in areas where visible mold
amplification was evident prior to remediation. In addition, indoor and
outdoor baseline air samples should be collected and analyzed to determine
the presence of residual indoor air mold contamination in the affected areas of
the property,

V1. LINUTATIONS
Reasonable effort has been made by EXCEL personnel to locate and sample the affected area(s)
for mold amplification. Mold growth may occur in various areas of a property wbere
water/moisture leak(s) are not addressed. These areas include eavitiesienclosures and adjacent
building materials, which house plumbing/drainage lines and areas adjacent to the
perimeter/enclosure system of the building. This assessment did not include areas not known to
have been affected by waterfmoisture damage or inaccessible areas. Therefore, the potential for
mold growth in these areas cannot be dismissed at this time. This report is intended for use in
planning remediation and construction activities and is not intended for use as a document to
render health-related opinions.
EXCEL appreciates the opportunity to sere as your consultant on this project. Please contact

Environmental mot)itoring Group (EM Q) was retained by A Beam Construction to perform a
post re-mediation air sampling and a microbial evaluation at a commercial building property
located on 267 East Badillo Street in the city of Covina, California. W, John Pbam with EMG
performed this evaluation, this evaluation focused on 4 different containment area which
includes kitchen, reception office, Pro-offices and Deputy office area inside containment, which
bad beet impacted by previous fimgal growth to the structure said had been subsequently re-
mediated.
In conducting this investigation, EMG performed air sampling for nonviable fu4 within the
residence and in the outdoor air to determine if the residence can be released for re-construction
work. The scope of sampling was limited to the collection of four indoor and one outdoor air
sample for the determination of non-culturable fungi.
This report presents the results of the microbial evaluation for non-viable fungi air sampling and
our observations made dwing this field investigation, Laboratory information is provided in the
Appendices.
2.0 BU[LDING DESCRTMON
TTlio comracrcial property that was evaluated is a one story building property. it is constructed on
concrete slab foundation. The affected are four different contauunerrt areas which includes
kitchen, reception office, Pro-offices and Deputy office area inside containment, which had been
impacted by previous fungal growth to the structure and had been subsequently re-mediated.
3.0 BUILDING OBSERVATIONS
EMG inspected the construction materials and their present condition (to the extent feasible and
practical) and furnishings to identify conditions that could contribute to microbial amplification,
and poor indoor air quality.
There was no visible suspect mold growth and musty/mildew odor observed during this
evaluation. The water-damaged materials (drywall .material) had been removed to the extent
feasible during the re-mediation in the affected areas. Moisture content of the wall, components
was measured and all readings registered below 1S percent. Any reading greaser than l5 percent
deems the substrate as significantly wet or satrnrated, which can lead to potential fungal growth
or wood decay.
4.0 SAMPLING ME'T'HODOLOGY, RESULTS AND DISCUSSION
EMG conducted air sampling for non-viable fungi within the lcitch=, reception office, Pro.
offices and Deputy office area inside containment work area and an outdoor air (for comparison).

Spore trap air samples for non-viable fungi samples were submitted to an independent
microbiology laboratory for microscopic evaluation and fungal identification, The remits of air
sampling for non-viable (spore-trap) fungi are Summarized in Section 4.3.1. Sampling results are
also disoussed in the sections below.
4.1 METHODOLOGY
Air samples for noD.viable ;fungi were collected using Zefon Air-0-Cell cassettes for
microscopic fungal identification and enumeration. Samples were collected at a flow rate of 15
liters per minute for a period of 5 minutes (75 liters).
4.2 AM SAMPLING RESULTS
EEG collected two indoor and one outdoor spore trap air sample during the course of the
evaluation. The total fungal concentrations of the indoor sample is 619, 1.189, 1289, 1598
structures per cubic meter (FS/m3), inside work area (inside containment), wheroas, the
concentration of the outdoor sample is 2,836 FS/m3. Fungi identified in bout the itadoor acid
outdoor air samples includes, A=spores, Asp-Pen like, Basidliospores and Cladosporium.
4.3 DATA INTERPRETATION
4,3.1 Non-Viable Air Samples
Results of sampling for ton-viable fungi taken indicate that the total indoor concentration. is less
than, that of the outdoor concentrations- Furthermore, the biodiversity of indoor and outdoor fuzigi
samples was found to be relatively similar when compared to fungal spores identified indoors.
Ail other fungal spores identified are common to the outdoor environment. These results do not
indicate the presence of a fungal reservoir it) the containment areas,
4.4 REGULATORY GUIDELINES
No national and interoational quantitative exposure level regulations or reoommended guidelines
have been established by occupational health standard-setting agencies (e.g., OSHA or NIOSH)
or professional associations (e,g., ACGIH or AMA) for "safe" exposure lialits to Aingi or
bacteria. There is international consensus, however, that in a well-maintained building, indoor
airborne fungal or bacterial concentrations will be lower tt= outdoor concentrations and the
type and relative percentages of fungi will be similar, except at lower concentrations, indicating
that indoor fungal reservoirs or amplification (growth) sates are not present

5.0 RECOMWNDA TIONS
Based on the results of the post re-mediations air swVling performed, the microbial evaluation,
and observations of the areas re-mediated for water damage, the re-mediation effort was
considered successful in haviAg reasonably eliminated structural mold growth associated with
the subject lose. These areas can be released for re-construction work.
Mold, Mildew and fiuigi area naturally occurring, as such, the owner takes responsibility for the
repair and water intrusion and humidity/climate control. Mold growth is known of occur in
hidden area where chronic and recurrent water releases, may occur in residence. These areas
include wa1Ls and insulating materials in bathroom, kitchens, laundry room, garages and attics
under leaking roof. This evaluation & inspection reported here did not include area not knows
to have been affected by aeoidental water release.
