February 12, 2014 the City Commission approved to amend the City's Storm Water Management Master Plan by modifying the
design criteria for the tailwater elevation and adopted an elevation of 2.7 ft-NAVD for all tidal boundary conditions. The Public
Works Department(PWD) requested that staff implement the enhanced stormwater system criteria including increasing from 6-
inch to 7.5-inch,5-day,24-hour rain event.
On March 5, 2014, the City Commission adopted Resolution No. 2014-28528 approving Amendment No. 3 for the re-design and
permitting phase services associated with the enhanced stormwater system criteria.SS&A completed their design,and submitted
it to Miami-Dade County Department of Regulatory and Economic Resources(RER), Environmental Resources Management for

to PWD and concurrently,change order negotiations were taking place with Lanzo Construction.
The City retained AECOM to assist in the implementation of a citywide comprehensive flood management plan and to review
stormwater improvement plans prepared by City's Consultants. On October 13, 2014 a follow up meeting took place in the City
Engineer's office and additional design modifications were identified and added to the scope. Based on the comments issued by
the City Engineer,SS&A had to revise stormwater drainage plans to meet the new criteria implemented by the City Engineer.

meeting was to discuss the stormwater pump station design and the process of constructing the improvements within the
easement. The meetings with residents took place from February to March 2015. The residents expressed great concern on the
visual impacts from the proposed structures and equipment components associated with the pump station installations.As a result,
on April 1, 2015, a meeting was held with concerned residents,their legal counsel, and staff from CIP, PWD, the City Attorney's
Office and the City Manager's Office. It was determined that the City would explore alternatives attempting to minimize the visual
impact of the stormwater pump stations and related components.
In order to maintain the project on track, and to minimize impacts on the overall schedule, this change order will capture all
stormwater drainage conveyance components that can be installed without affecting the exploration of possible alternatives
related to the installation of pump stations.The work related to the pump stations is not included in the scope of this change order.

BACKGROUND
Pursuant to Invitation to Bid (ITB) No. 49-11/12, for the Right-of-Way Infrastructure
Improvement Program — Venetian Islands Bid Package 13C, on March 13th, 2013, the
Commission approved Resolution No. 2013-28163, recommending the award of a
construction contract to Lanzo Construction Co. Florida, (Lanzo) in the amount of
$9,699,509 base bid plus $640,028 for selected alternates (sanitary sewer lining and
road reconstruction) and a project contingency in the amount of $1,033,954; for a total
construction cost of$11,373,491.
On February 12, 2014, the City Commission approved Resolution 2014-28491,
recommending Change Order No. 1 to the construction contract with Lanzo Construction
Co. Florida, for the purchase and installation of automatic meter readers in the amount
of$195,532, plus contingency in the amount of$19,553, for a total of$215,085.
As recommended by the Mayor's Blue Ribbon Panel on Flooding and Sea Level Rise
and the Flooding Mitigation Committee, on February 12, 2014 the City Commission
approved to amend the City's Storm Water Management Master Plan by modifying the
design criteria for the tailwater elevation and adopted an elevation of 2.7 ft-NAVD for all
tidal boundary conditions. The Public Works Department (PWD) requested that staff
implement the enhanced stormwater system criteria including increasing from 6-inch to
7.5-inch, 5-day, 24-hour rain event. The new criteria required the Engineer of Record,
Schwebke-Shiskin & Associates (SS&A) to revise the design included in the contract
documents for this project.
On March 5, 2014, the City Commission adopted Resolution No. 2014-28528 approving
Amendment No. 3 for the re-design and permitting phase services associated with the
enhanced stormwater system criteria.
SS&A completed their design, and submitted it to Miami-Dade County Department of
Regulatory and Economic Resources (RER), Environmental Resources Management for
approval. On July 22, 2014, RER issued approval for the revised design. On August 5,
2014, the revised design was submitted to PWD and concurrently, change order
negotiations were taking place with Lanzo. Occurring on a parallel path with the change
order negotiation, the City's Public Works Department (PWD) was in the process of
completing their final review of the revised stormwater improvement plan when, the
Mayor's Blue Ribbon Panel on Sea Level Rise directed PWD to provide the revised
stormwater improvement design to AECOM for their review.
The City retained AECOM to assist in the implementation of a citywide comprehensive
flood management plan and to review stormwater improvement plans prepared by City's
Consultants. On October 10, 2014, AECOM reviewed and issued comments. On
October 13, 2014 a follow up meeting took place in the City Engineer's office and
additional design modifications were identified and added to the scope. Based on the
comments issued by the City Engineer, SS&A had to revise stormwater drainage plans
to meet the new criteria implemented by the City Engineer.
On November 19, 2014, the City Commission adopted Resolution No. 2014-28821
approving Amendment No. 4 to SS&A Agreement to implement additional enhanced
stormwater drainage design modifications to existing design and incorporate AECOM's

review comments issued on October 10, 2014 plus other comments issued on October
13, 2014 by the City Engineer.
On February 18, 2015, SS&A responded to additional comments issued by AECOM and
finalized the enhanced stormwater drainage design modifications and on February 23,
2015, submitted the 100% documents to PWD for final review.
Once the design was completed, the Capital Improvement Projects Office (CIP)
contacted the twelve (12) property owners that reside adjacent to the six (6) easements
where the stormwater pump stations were proposed to be located. The purpose of the
meeting was to discuss the stormwater pump station design and the process of
constructing the improvements within the easement. The meetings with residents took
place from February to March 2015. The residents expressed great concern on the
visual impacts from the proposed structures and equipment components associated with
the pump station installations.
As a result, on April 1, 2015, a meeting was held with concerned residents, their legal
counsel, and staff from CIP, PWD, the City Attorney's Office and the City Manager's
Office. It was determined that the City would explore alternatives attempting to minimize
the visual impact of the stormwater pump stations and related components.
On April 15, 2015, the City Commission adopted Resolution No. 2015-28993 approving
Amendment No. 5 to SS&A Agreement for additional Construction Administration and
RPR services due to the increased construction schedule plus design modification
services required to minimize the impact of the proposed structures and components.
The design modifications will include conceptual design, meetings with City staff,
electrical and structural revisions and permit submittals.
ANALYSIS
In order to maintain the project on track, and to minimize impacts on the overall
schedule, this change order will capture all stormwater drainage conveyance
components that can be installed without affecting the exploration of possible
alternatives related to the installation of pump stations. The work related to the pump
stations is not included in the scope of this change order. The scope of work, for this
change order, will include; stormwater drainage structures with all associated pipes and
drainage inlets, concrete valley gutter, roadway reconstruction, first and second lift of
asphalt and driveway aprons.
Lanzo has presented a change order proposal, (Attachment A) that address the
following:
• Additional scope relating to stormwater drainage conveyance improvements
designed to comply with the City's new stormwater.
• Exercising the provision of Article 38.1.1 of their contract with the City of Miami
Beach that allows for the adjustment of unit prices from the original contract
wherever the unit quantities are adjusted in excess of 20% of the original
amount.
• Effects of recently imposed weight restrictions on the Venetian Causeway
bridges.

Re: Venetian Island iVeighborhood 13 BID Package "C"—Drainage Redesign Proposal
Analysis(Drainage Collection System Only)
Dear David,
As requested, we have completed our review of the Change Order proposal provided by Lanzo
Construction Company for a portion of the drainage improvements designed to comply with the City's
recent sea level rise criteria. The portion of the drainage improvements in Lanzo's proposal includes all
drainage construction upstream of the designed water quality units for each respective island. Note that •
the proposal includes full road reconstruction of all roadways as mentioned in more detail in this letter.
Based on the most recent information provided to us in a proposal by Lanzo Construction Company dated
April 27,2015 and in summary of our review of the project costs:
Total Stormwater Redesign Improvements(Excluding Pump Stations&•Outfalls)_ $2,834,683.00
Bridge Weight Restriction Cost Impact= $1,200,461.00
Unit quantity increases/decreases greater than 20%= $54,950.00 u
Original Contract Amount, including change orders= $11,588,575.13 .
Total Project Cost= $15,678,669.13 •
The change order proposal submitted by Lanzo Construction Company included a combination of Unit
Price and Lump Sum values for change order work.
- Pursuant to Article 38.1.1 of the contract between the City of Miami Beach and Lanzo
Construction Company(ITB 49-11/12)we found that unit prices from the original contract were
used wherever the unit quantities did not exceed 20%of the original amount. However due to
recently imposed weight restrictions on the Venetian Causeway,Lanzo Construction Company
provided supporting documentation used to determine the additional cost of construction to
comply with the regulated bridge weight restrictions. Based on the documentation provided,the
weight restrictions on the Venetian Causeway require that the number of trips needed to import
and export materials to and from the project be increased to transport the mentioned materials in
lighter loads. We find that the documentation provided clearly defines the impacts of the
bridge loading restrictions,however,please note that the change order proposal and supporting
•

documentation provided by Lanzo Construction Company was not independently verified by this
firm and that our firm does not have information available on the pricing structure and
comparison of Lanzo's truck capacities used in the original contract. As such,for our review of
the supporting documentation,we could only assume that the truck capacities used to bid the
project were based on full truck loads as shown in the supporting documentation.
- Pursuant to Article 38.7 of the contract between the City of Miami Beach and Lanzo Construction
Company(ITB 49-11/12),where unit quantities increased or decreased more than 20%of the
contracted quantities,we found that Lanzo Construction Company adjusted unit prices based on
negotiated values. It is our opinion,to the best of our knowledge,that the negotiated values of
these items are within an acceptable value..
- Pursuant to Article 38.1.2 of the contract between the City of Miami Beach and Lanzo
Construction Company(ITB 49-11/12),a change order for individual items proposed for
construction that were not included in the original bid documents was provided. The proposal
provided by Lanzo Construction Company included a redesigned drainage collection system,
furnishing and installing FPL conduits and pullboxes for anticipated electrical systems,and
fitrnishing and installing a geosynthetic grid below the proposed roadway limerock base. Based
on our review of the change order proposal for these items it is our understanding that a
component for overhead and profit is included and to the best of our knowledge it is our opinion
that the unit prices for these items are within an acceptable value for the work proposed.
•
Our review consisted of an independent cost analysis while also taking into consideration the unique
circumstances regarding the bridge loading restrictions of the Venetian Causeway. Using these factors
we determined that the cost proposed by Lanzo Construction Company an acceptable value for the
proposed work.
1
It is our understanding that the project duration is anticipated not to exceed 12 months from the date of
Notice to Proceed for construction of the re-designed collection system. As such,it is our understanding
that the total project duration shall be 422 days from last day of the original contract date(2/2/2015).
Based on this duration,we find that the Final Completion date of the project shall be March 31,2016.
As always,if you have any questions please contact me.
Respectfully submitted,
