Item 4D Memo[Type text] Item 4D Page 1 of 2 M E M O R A N D U M (March 6, 2018) To: Shana Yelverton, City Manager From: Rob Cohen, Director of Public Works Subject: Award a construction contract for Whispering Lane and Whispering Dell Court Water Distribution System Improvements project to Wildstone Construction, LLC in an amount not to exceed $580,000. Action Requested: Award a construction contract for Whispering Lane and Whispering Dell Court Water Distribution System Improvements project to Wildstone Construction, LLC in an amount not to exceed $580,000. Background: Whispering Lane and Whispering Dell Court Water Distribution System Improvements are located in the Whispering Dell Estates subdivision. The improvements entail waterline replacement including all its appurtenances as well as complete pavement rehabilitation. Whispering Dell Estates is an older development with an aging water system that requires frequent repair and maintenance. The paving rehabilitation will repair existing deficiencies and provide a clean end product so there is no patching as a result of the waterline replacement. Two (2) bids were received on Tuesday, February 13, 2018. The bids have been reviewed by Baird, Hampton & Brown, Inc. and City Staff. The BHB Opinion of Probable Construction Cost was $546,600.00. Below are the bid tabulations: BIDDER BID AMOUNT Wildstone Construction, LLC $553,017.00 TexGlobal Contractors, Inc.** $464,009.40 **TexGlobal Contractors, Inc. did not provide the best value criteria (key personnel, similar projects, and references) required by the contract documents. Thus, their best value score was substantially lower than Wildstone Construction, LLC Item 4D Page 2 of 2 The recommended contract award amount for the base bid is $580,000. This award amount is within budget. All work associated with this project must be complete, by contract, in less than 120 working days once notice to proceed has been given. Financial Considerations: Funding for this contract has been allocated through the FY 2016 and FY 2018 Water Impact Fee and General Fund Residuals. Strategic Link: This item relates to the City’s strategy map focus areas of Infrastructure. The specific corporate objective that is met by this project is to (F2) Invest to provide and maintain quality public assets. Citizen Input/ Board Review: N/A Legal Review: N/A Alternatives: The City Council may approve or deny this amendment. Supporting Documents: Recommendation Letter Bid Tabulation Location Map Staff Recommendation: Award a construction contract for Whispering Lane and Whispering Dell Court Water Distribution System Improvements project to Wildstone Construction, LLC in an amount not to exceed $580,000.

The City specified that the contractor would be selected based on Best Value,with the following weighted criteria: 50% Purchase Price (bid price) 15% Reputation of Bidder and Key Personnel 15% Reputation of Work and Product Quality 10% Relationship with City of Southlake 10% Responsiveness A detailed tabulation of bid prices is enclosed. Bid tabulations are summarized as follows: BHB Opinion of Probable Construction Cost $ 546,600.00 OPCC Wildstone Construction, LLC $ 553,017.00 101%ofOPCC TexGlobal Contractors, Inc. $464,009.40* 85%of OPCC *Note that a discrepancy between the unit price in words and the unit price in figures for bid item#10 in TexGlobal's bid worksheet resulted in a$1,608.00 reduction in the bid price,compared to what was read out during the proposal opening. To evaluate the reputation of the bidder, key personnel, work, and product quality,the Notice to Bidders required a list of at least five similar, completed projects. Results of BHB's investigation of qualifications and references for each contractor are as follows: 1. Wildstone provided references for more than five similar, completed projects, including two projects that BHB designed. Feedback was universally very positive from three municipalities having experience with Wildstone and/or its subcontractor PaveCon. The BHB engineering project manager also reported a good experience with Wildstone. The municipalities reported that the infrastructure Wildstone and/or PaveCon constructed 2-4 years ago is in good working order,and no issues have arisen since the infrastructure was placed in service. 38011villiamUate,Suite500I Grapevine,TX760511 P8:817-251.85501 FX:817-251-8810 TBPE Firm#44,TBPLS Firm#10011300, #10011302,#10194146 engineering I surveying I landscape E:\2016.000.000\201e.723.000\Dou\&tl&Award Prmess\Best Value evaluation and recommandation.doca Mr.Jim Flint, PE February 19, 2018 Page 2 of 2 2. TexGlobal stated in its proposal that the company was formed in March 2017,described one project that is currently in construction, and provided no contacts for references. Despite the lack of information, I thought it was in Southlake's best interest to thoroughly evaluate the proposal with the most favorable bid price, which might ultimately result in the best value to the City. Among my resources, I spoke with one person with municipal oversight responsibility for the project TexGlobal described in its proposal,from which I learned the water line portion is complete and in service. I also spoke with two other people familiar with the key personnel listed. Half of the feedback was positive. I understand from our conversation between myself and City of Southlake staff after the proposal opening,that the City has not been engaged in any contract with either Wildstone or TexGlobal. Wildstone is believed to have done other construction within city limits with no known issues. Based on these figures and findings, and excluding the 10%factor of contractor relationship with the City, BHB's contribution to the Best Value evaluation is summarized here: RANK SCORE CONTRACTOR 1. 88 Wildstone Construction, LLC 2. 60 TexGlobal Contractors, Inc. A copy of the Best Value worksheet is enclosed for your reference. I did not attribute a final score,assuming the City would normally perform further evaluation. However,TexGlobal's lack of similar, completed projects is a shortcoming I believe they cannot overcome,even if they had all positive references. Further,the City would likely be justified if it rejected TexGlobal's proposal for not meeting the requirement in the Notice to Bidders regarding evidence of having completed similar work. The information Wildstone included in its packet indicates completion of 12-15 projects in each of the past two years, and 7-8 projects in each of the two years prior. Wildstone is based in Fort Worth,TX, with a bonding capacity exceeding$10 million. Wildstone's proposed paving subcontractor PaveCon is headquartered in Grand Prairie,TX,and provided a list of eight municipal projects with contract value up to $5 million. BHB therefore recommends Wildstone Construction, LLC for the Water and Paving Improvements-Whispering Lane& Whispering Dell Court construction project. As written, the contract documents stipulate that the City is responsible for testing,for which we anticipate $10k±in additional expenses. Furthermore, the potential for change orders is always present and we typically suggest budgeting 5%to 10%for this possibility. BHB recommends the total construction budget be set at minimum $590,700, up to$ 618,300, depending on the City's preference for availability of contingency funds. I look forward to completing this project with you.
