CITY OF HALLANDALE BEACH

MEMORANDUM

DATE:                        October 28, 2008

TO:                D. Mike Good, City Manager

FROM:           William M. Brant, P.E., Director, Public Works, Utilities and Engineering

SUBJECT:     Completion of Barrier Wall Construction around Public Works Compound

PURPOSE:

Pursuant to Chapter 23, Section 23-107(5), Unique Circumstances, request authorization to award Shanco Construction Company a contract in the amount of $392,746 to complete construction of barrier wall around the Public Works Compound.

BACKGROUND:

The City of Hallandale Beach has recently completed construction of its new Membrane Treatment Plant at the Public Works Compound.  One of the primary components of the project, a deep injection well, is located on the southwest corner of the compound.  Previously this area was not protected by a barrier wall.  In order to provide a level of security appropriate for this major component of the City’s water production system and in order to provide a barrier that increases the aesthetics of the compound to the adjacent community, the City recently contracted the installation of a barrier wall around the property of the deep injection well.  This work was performed by Shanco Construction Company subcontracting under J.J. Kirlin, the City’s contractor for the Membrane Treatment Plant project.  The wall construction was completed in September.  Pictures of this wall are attached to this item.

DISCUSSION:

While the installation of the wall succeeded in providing needed security for the deep well area, the remainder of the compound is not as well protected.  It would be beneficial to extend this level of security to the Membrane Treatment Plant and the remainder of the Public Works Compound as the Membrane Treatment Plant can be accessed from other sections of the compound.  The wall in the vicinity of the new plant is old and less stable.  Several years ago a portion of this wall fell down and required a patched repair.  The old wall is 7 feet tall, and the new one is 8 feet tall.  The new one is also built to withstand 150 mph hurricane force winds.

Staff believes the surrounding community is better served by a uniform attractive barrier.  There is a stark contrast between the new wall and the old from an aesthetic perspective.  Pictures showing the contrast between the old and new walls are attached.

In order to be consistent both in appearance and in strength, staff recommends utilization of the same contractor that performed the construction of the wall around the deep well.  Shanco Construction Company completed the initial installation and has submitted a base quote of $374,044 and a rate for other charges that may arise from the need to install additional columns to avoid disrupting underground utility lines.  Staff estimates these expenses will not exceed 5% of the base quote.  The total cost will not exceed $392,746.  Staff is in the process of comparing this quote with quotes from other construction companies to assure the cost is reasonable. 

Sufficient funding in the amount of $691,461.30 for this construction is available in CIP #973301, Membrane Water Treatment Plant, Account No. 430-3395-533-6613.

RECOMMENDATION:

Pursuant to Chapter 23, Section 23-107(5), Unique Circumstances, request authorization to award Shanco Construction Company a contract in the amount of $392,746 to complete construction of a barrier wall around the Public Works Compound.
