Mr. Dietz: A successful bid opening was held at the Eden Prairie Fire Station on December 4, 1986, for the Water Supply Improvements , Contract No. 2, City Project No. 52-072B. A total of 11 bids were received for the various sections, including two contractors who submitted bids for two of the three sections. The bids are tabulated below: r CONTRACTOR AMOUNT SECTION I - WATER WELL CONSTRUCTION 1. Layne-Western Company, Inc. $ 475,000.00 Long Lake, Minnesota 2.

Park Construction Company $ 465 ,060.000) Fridley, Minnesota (1) If awarded Section II and III, a deduct of 1 percent was offered We have included a copy of the bid tabulation for your records . The total of the low bids for all three sections is $2, 285, 315 . 25, which is $35,315.25 higher than the opinion of probable construction cost of $2,250,000 prepared by Black & Veatch, a difference of approximately 1. 5 percent. We believe this is due to the large volume of construction work presently occurring in the Twin Cities. The following is a discussion of the low bidders for each section. 1 . For Section I, the low bid of $475,000, submitted by Layne-Western, was $90,500 below the second low bid, and $5,000 below the opinion of probable construction cost of $480,000 prepared by Black & Veatch. Layne-Western has performed well construction work on numerous Black & Veatch projects across the country and we feel they are one of the better well drillers in the business; however, most of these projects were not performed using the specified cable tool method of drilling. We have checked on several of their references for projects where Layne-Western did use the cable tool method , and have found that they performed satisfactory work. They have indicated that they will do almost all the work themselves, with the possible exception of a small earthwork subcontract. We feel that Layne-Western will be able to construct high quality wells for the City. We have reviewed the Layne-Western bidding documents and find them to be in order; therefore , we recommend that Layne-Western be awarded Section I of Contract No. 2. BLACK ac V EATC H Mr. Gene Dietz 3 B&V Project 12106.CPS Eden Prairie, Minnesota December 11 , 1986 Included in Layne-`western's bid submittal was a letter offering a deduct of $37,200 if they were allowed to use the reverse circulation drilling method in the formation, in lieu of the specified cable tool drilling method. We have reviewed this alternative, and feel that the proposed method of construction is unproven in the Twin Cities area. We therefore recommend that the specified cable tool method be required for this project, and the deductive alternative not be accepted. 2. The low bid for Section II , submitted by Barbarossa and Sons, was $1, 447, 700. This is $19,300 below the second low bid, and $27 ,700 higher than the opinion of probable construction cost of $1 ,420,000 prepared by Black & Veatch. Although the low bid was approximately two percent above the opinion of probable construction cost , we feel that the low bid is an acceptable price for this section as indicated by the other bids for Section II which were within 10 percent of one another. Barbarossa and Sons has worked on Black & Veatch projects in the past including the 1981 water plant expansion at Eden Prairie, and we have found them to be a competent contractor with the ability to satisfactorily perform the work for this section. We have discussed the proposed subcontractors with Barbarossa and Sons, and find that they intend to do the majority of the general and mechanical work. One major subcontractor, Layne Minnesota, will supply and install the well pumps. Layne Minnesota has also worked on previous Black & Veatch projects , including Eden Prairie' s Wells No. 4, 5 and 6 which were constructed in 1981. We feel that Barbarossa and Sons and Layne Minnesota will be able to construct high quality well houses for the City. We have reviewed the Barbarossa and Sons bidding documents and find them to be in order; therefore, we recommend that Barbarossa and Sons be awarded Section II of Contract No. 2. 3. For Section III , the low bid of $362,615.25 was submitted by J. P. Norex. This price is $13,835.75 below the second low bid, and $12 ,615.25 higher than the opinion of probable construction cost $350,000 prepared by Black & Veatch. Although the low bid was approximately 3.6 percent above the opinion of probable construction cost , we feel that the low bid is an acceptable price for this section as also indicated by the fact that the three lowest bids were within 6 percent of one another. J. P. Norex is currently working on several water and sewer projects for Eden Prairie, as well as other municipal projects in the Twin Cities area. One of the other projects involves a ductile iron sewer pipe supported by piles, which is similar to some of the construction required on this project. We understand that the City is satisfied l � BLACK & V E A T C H i Mr. Gene Dietz 4 B&V Project 12106. CPS Eden Prairie, Minnesota December 11, 1986 with their performance. Norex has indicated that they plan to do most of the work themselves, and will not have any major subcontractors on the project. From what we have learned it appears that J. P. Norex is qualified to do the work for this section. We have reviewed the J. P. Norex bidding documents and find them to be in order; therefore, we recommend that J. P. Norex be awarded Section III of Contract No. 2. Should you have any questions or wish to further discuss our recommendation-' , please contact us. Very truly yours , BLACK & VEATCH i J. L.
