Generally, perforated pipe is used to accelerate the removal of subsurface water in soils or to allow storm water to percolate into the soil.Currently,two classifications of perforations are specified in the AASHTO material specifications for HDPE pipe: Class I,and Class II. Class I perforations are commonly used in combination storm/underdrain systems while Class II incorporates subsurface drainage and detention/retention systems.Both classes are explained in more detail in the AASHTO materials specifications(M294 and M252).AASHTO M252 covers pipe diameters 3-through 10-inch(75-250 mm) while M294 covers 12-inch through 60-inch(300-1500 mm). Standard Perforation Patterns AASHTO Class II Perforation The following terminology for perforations is derived from the applicable AASHTO specification. Differences between the specifications are covered in the table below. Class II perforations shall be located in the outside valleys of the corrugations,be circular and/or slotted and evenly spaced around the circumference and length of the pipe.The perforations shall be located in the outside valleys of the corrugations.The water inlet area shall be no less than 0.945 in2/ft(20 cm2/m)for pipe diameters 4-through 10-inch(100-250mm), 1.42 in2/ft (30 cm2/m)for pipe diameters 12-through 18-inch(300-450 mm)and 1.89 in2/ft(40 cm2/m)for pipe diameters larger than and equal to 24 inches(600 mm).

KENT 1 LS Erosion Control addition for Clearwell#2 and Creek Berm $ 182,629.43 $182,629.43 WHY: It became evident during construction that there was excessive erosion on recent excavation and sloping of the fill material around the existing clearwell. This excavation was required to construct the new High Service Pump Station. Soil utilized during backfill of the clearwell during its original construction, experienced erosion well beyond design expectations during construction of the High Service Pump Station foundation. This was not anticipated and a new erosion control measure design was required to permanently stabilize the slope. HOW TO AVOID: Additional soil borings and test during design could have avoided the need for this change but not the costs associated. From:Grady Atkinson [mailto:gatkinson@Invinc.com) Sent:Monday, November 20,2017 10:51 AM To:Kent Power<KentP@cctexas.com>;Alex Barabanov<AlexBa@cctexas.com> Cc: Marcus Naiser<mnaiser@Invinc.com>;Victor Vargas[Engineering)<VictorV2@cctexas.com>;Arturo Hernandez<ArturoH2@cctexas.com>;Jiangang Deng<JiangangD@cctexas.com>; Ernesto De La Garza <ErnestoDLG @cctexas.com> Subject: FW: RFP#8 Erosion Control for CW#2 and creek berm Kent/Alex, Attached is PLW's proposed cost for the addition of CW2 and creek erosion control to be added to their scope of work. LNV reviewed PLWs initial proposal and provided comments which have been addressed by PLW in the email below. I want to note that I'm ok with allowing larger stone to be used in lieu of the size specified in our design only if it is at a cheaper price. The larger stone will enhance protection of the berm down at the creek. I'm also ok with allowing 12"pipe in lieu of 8"only if it is at a cheaper price. The larger pipe size will increase the handling capacity of the drainage system proposed. I took a look at the existing wedge anchors during a site visit last week and some do look to be in a poor condition. That said and in regards to PLWs response below, I would expect some of the existing wedge anchors to be replaced. An exact number will not be known until they begin installation,so it's up to the City on how this item needs to be addressed initially. All in all,the big ticket item on this proposal is labor/equipment costs(approximately 70%of the cost). Materials are approximately 30%of the proposal cost. In my experience, I typically see labor/equipment percentage of cost around the 50%range as well as the material percentage of cost. Evaluation of the time estimated in the proposal for the work at hand seems reasonable,so it's hard to argue labor overweighting the cost. The only thing that can be looked at further would be to compare the labor unit rates to PLWs certified payroll,which Construction Services has in hand. Other than that, I have no additional comments and so I am submitting to the City for approval. If there are any questions or you would like to discuss,please don't hesitate to contact me.

Please review these comments and address at your earliest convenience. 1. Item 10(Page 2)—Fine grade,excavation and backfilling($7,004) Comment:The Landlok 300 is being proposed in a location that is already proposed to be graded in the original set of plans. Please provide explanation on why additional grade,excavation and backfilling is required.After the installation of the drain pipe there will be pea gravel from the existing drain mixed with dirt we dig up on this scope of work. The area will need to be regraded to a clean flat surface there is also excavation and backfill at the toe of the trench(figure 3 drawing C18B)That is not included in item 2. 2. Item 22&38(Page 2)—Water Truck($15,000) Comment:The unit rate for a water truck is reasonable for a day rate rental in this area;however, it is specified to be used for a total of 30 days. That said,it is typical that a reduced rate is provided when rented for an extended period(such as renting by the month or week in lieu of a day to day basis). Please provide rental quote and/or explanation supporting the$500 unit rate. Please provide the same information for Items 33 and 35 as they are proposed for 20 days as well.Considering a monthly rental(1 • month instead of 20 days),we can reduce the price for the water truck to$7,300, Mini excavator to $4,250 and skid steer to$4,800. 3. Item 25(Page 2)—4x12 Stone(if available) Comment: Please confirm 4x12 Stone"is available"at the cost of$35.5 per ton.The only product we can find in a small order is 8"to 12"crushed concrete.That price is good 1 to 2 weeks lead time is required.It would come from Southern Crushed Concrete.The product will be crushed concrete.See attached quote. I did find stone in San Antonio$100 a ton. 4. Item 29(Page 2)—Wedge Anchors($3,980) Comment: Please provide purpose for the wedge anchors and confirm if they are needed or not. If not needed,please remove item and associated cost from the proposal.The existing metal bracket looks in good shape but I'm not sure every nut will be able to be removed off every stud.Some or most may need to be cut off and new ones added. If you are agree we can consider 50%of new anchors in a safe position. 5. Item 40(Page 2)—Small Equipment&Consumables($4,000) Comment: Please provide detail on what all equipment is included in the item"small equipment"with detailed cost breakdown for each equipment included.Generator 20 days($705),Water pump 20 days ($657),Air compressor chip and hummer 10 days($886),Eye level 20 days($894)and consumables ($768). 6. Item 43(Page 2)—Foreman($7,460) Comment: It appears man-hour costs are already provided for each individual scope of work. Please provide detailed explanation for purpose of Item 43.It will be for the supervision,as you can see we haven't added any general condition for those works. 7. (Page 4)—French Drain Pipe Cost Proposal Comment: Please provide explanation for why 12"perforated pipe is quoted in lieu of 8"as specified in the drawings and the cost difference between the two sizes.8"perforated pipe was not available from any of our venders.To buy 8"drill and rap the pipe was much higher with the labor included.The 12"is a stock Item next size down was 4"or 6" but we never had it quoted. 8. Item 40(Page 6)—Powerstud 304SS''/:X 4''A(50/BX) Comment: Please provide detail for the purpose of this item.This would be the concrete anchor used to hold the Batten or metal strip on the wall if the others are not reusable. If there are any questions, please don't hesitate to contact me.
