Surname 1 Name: Instructor: Course: Date: Assessment of the Estimates The successful construction of the torrent stream flood control dam would require careful planning and at the same time forceful execution. The mere fact that this will be a flood control dam gives the work a great scope that demands major construction and engineering endeavor that further requires a great set of skills that will ensure not only timely completion but also economical completion. After going through the preliminary estimator estimates, notes and comments, I have concluded that not much needs to be changed from what I understand dam construction proceed with similar activities sequences during the development that results to construction. This progression begins with the initial investigation of the sites where the dam will be constructed, a component of the project that will befit the site and project configuration. The work done by the estimator covers the cost that will be incurred while I do not disagree with the estimates I can see that some important information to do with the dam construction was ignored. It is clear that the complexity and work scale was not specified which might result in a further increase in cost. The cost I see that is material, labor and equipment cost is quoted from the market which might significantly increase when the actual cost are incurred. Considering that this is the second dam, it will be hard to tell whether water will flow in the same manner as it does in the first dam. Surname 2 I would propose that without actually stating the actual cost that a detailed cost is developed for the different project parts. The advantages of doing this are that it will allow easier identification of the basic drivers that are necessary for the estimation. These drivers are linked to quantity variation that is associated with location and nature of work being carried out and also the resources that will be used. Each part requires a different quantity of resources. In support of this there two types of cost that are necessary to have in mind that is the direct cost comprising of the labor, equipment, material, subcontractor cost and production rate cost. The indirect cost is the second type of cost that needs to be put into consideration. It is clear that the estimator completely ignored this cost which might end up hurting the budget set aside for this project. The indirect cost that I feel ought to have been put in consideration when the estimation was being made include the safety program, environmental program, quality control program, indirect equipment cost, job facilities and offices, general miscellaneous, warranty cost and insurance and construction surveying. Typically, every new project requires a different cost estimation based on the specification of the project plus the features required for that project. Considering this is a new project the expectation should, of course, be different from what the first dam looks. I am of the opinion that the cost estimation ought to reflect a reasonable defensive cost estimation which is more refined and displaying confidence and accuracy of the estimate. To ensure we do not go wrong on the cost estimation, we need to further branch the work into the following classes 1. Earth excavation 2. Rock excavation and hauling Surname 3 3. Construction of the blanket 4. Tunneling 5. Concrete operations 6. Mechanical items 7. And indirect cost Each of these work classes needs to be broken down into labor, equipment and material costs with the appropriate factor being applied. The cost that might arise as the project progresses includes the quantity variation whereby it is assumed that some things will remain constant such as the length and height of the dam, the intake tower that is the heights and foundations are good, and the spillway won’t make any impact that can affect the budget. In addition to quantity variation, we have the schedule and escalation whereby a cash flow profile was distributed over the given period by the estimator. However, to be practical, some work can extend by 10% in the first year and in the second-year time still extends. Time extension means an increase in cost and in each case the primary cost and the indirect cost ought to be adjusted in a manner that fits the new schedule otherwise work will stop. Another negligible cost that is not a must but necessary to consider is the exchange rate fluctuations which might have a bigger impact if the constructions material will be imported. All in all, I believe this is some of the most important facts that the estimator needs to consider when preparing the final estimation.

Sincerely, Tami Fish Project Addendum & Quote CEM 612 Construction Estimating Spring 2018 The intent of the final project is to provide a scenario giving you a framework to demonstrate your course understanding. Placing you in a realistic position that you may find yourself as a Project Manager will also help you bring the course to a conclusion. As with real situations Project Managers find themselves in, keep the end result in mind and don’t get lost in the situation. Congratulations! You have been hired as a Project Manager for a Local Construction Firm (LCF, Inc.). There is a bid due on May 21 for construction of a new flood control dam on the Torrent Stream. If the project is won, this will be your first project for them. If they don’t get the project, you could get fired. You should use the information provided to determine what risk is associated with the project and what items will not need to be considered. It should also provide some guidance on flexibility in negotiation, or in this case, how to approach the bid. With open ended projects, each statement usually has a specific impact and should be considered (ie. How does this statement affect and estimate?). This project is the second dam on this stream and is located about the same distance from a local materials pit as the first. LCF undertook the first dam project last year. It is only 10 miles from your main office so the boss really wants this job. The project is being contracted by the local municipality who have been awarded a federal grant so funds are in place and there will be no delay in receiving payments on pay requisitions. Although payments will be made based upon % of work complete and materials onsite, the Owner will not take ownership or liability for the project until final completion of the project. The municipality has also secured all necessary permits and easements for the project. The project is anticipated to begin on June 1 and be complete on August 30. The municipality holds an annual Fall Harvest Party on the riverfront in this area in early September so Liquidated damages in the amount of $200/day are included in the contract. Consider what has been covered in this class, potentially establishing a checklist from which to review the estimate. Course topics dealt with well by the estimator should be noted and commended, those missing or mishandled should be noted and if you find it easier to convey the information numerically, then that is recommended, but the intent is NOT to complete a numerical estimate. Course topics should include not only textbook topics but also topics included in personal research and posted. I finally understood open ended projects like this when a Professor explained it as if someone were “…walking through an orchard with the intent to identify the different fruit varieties. Pick some of the fruit as you go by each tree and inspect it, but it’s not necessary or recommend to harvest all the fruit from one tree as you won’t have time to walk through the whole orchard.” An estimator for the company (the owners kid) has been working on this for several weeks and has provided you with a preliminary estimate and their notes and comments. (Attached Excel File) You will need to comment on or correct this estimate as needed, provide the information that you can, and direct the estimator to determine other necessary information to complete a final detailed estimate for bidding purposes. Directions for the estimator should be detailed in methodology and limited to finding missing information that would be common knowledge to the firm. In order to give the estimator time to complete the bid, your report will be required no later than May 5th. The estimator is on vacation until May 5th and refuses to respond to emails or calls while not at work. You may contact the instructor with written questions, but think through the problem first as it may be best to document your concerns Project Addendum & Quote CEM 612 Construction Estimating Spring 2018 and discuss potential assumptions and solutions in your report. Written questions about the design may be asked of the engineer in the form of RFI’s until April 21, but answers to such questions will be made in written form to all bidders. Company policies are meant to be followed, or provide a good deal of justification why it wasn’t followed. LCF has estimating policies it expects all estimators and project managers to follow: 1. Labor taxes and insurance rates will be applied without regard to total pay – This assumes the project is the first of the year for the employee and allows for removal and replacement of employees without a loss to the company. 2. Each project will anticipate fringe benefits for employees. 3. Projects will account for anticipated delayed payments with current line of credit loan rates. 4. Projects will account for and track indirect project costs. The following Requests for Information (RFI) have been received: RFI 1: Is the design we are provided for the second dam the exact same as it would be for the first dam? If not, are the designs/as-builts for the first dam available? The structure of this second dam is the same as the first. Site conditions vary, affecting quantities of materials, clearing, etc., but new material specs are the same. RFI 2: Can we assume that the flow characteristics are the same as those provided (i.e. the first project hasn't affected the engineering aspects of the current project)? The second dam is located upstream of the first beyond any area of impoundment or impacts to stream flow for the second dam. RFI 3: How old are the quotes that the estimator received (can we assume those quotes are current)? The first project was constructed last summer so the values from the previous estimate are a year old. If it was indicated as quote for this estimate, it is current. RFI 4: I am not a construction engineer by trade or by education so I am a bit unclear when hydroseeding would be appropriate on a project such as our final. 3 possibilities occur to me, the hydroseeding could be applied near the beginning of the project, after site clearance, but the excavation and moving equipment around would probably tear most of it up. It could be applied after excavation and backfilling, which would disturb the hydroseed less, which is the direction that I am currently leaning. It could be applied near the end of the project for minimal disturbance, but also would provide minimal erosion protection. It could also be applied at both beginning and end of the project, if the Scope of Work indicated such. Hydroseeding is typically completed after an area has been final graded. Most contractors wait until the end of project to complete it. However, since we are near an active water source the areas should be final graded and stabilized as soon as possible per the NPDES permit. Project Addendum & Quote CEM 612 Construction Estimating Spring 2018 RFI 5: 1. What was this company’s last year’s revenues, and are this year’s revenues forecast to be significantly different? In what way? The company revenues will not be significantly different this year from last and you do not need to anticipate any significant changes. 2. Is the equipment operator trained and licensed to operate a 70’ boom crane? Yes What bonding requirements does the project have? Assume a bond rate of 2% of project bid. What general liability coverage does the company currently have? The company is financially stable and is self insured. 3. 4. RFI 6: 1. 2. 3. Is it acceptable to consider cofferdam options other than the indicated sandbags? Yes, a word of caution. Cofferdams can incur some significant costs, but provide a level of safety and security on a project. Instead of building the spillway in two 50’ sections, can it be built in a 60’ section and a 40’ section to avoid the concrete seam being located on the rock anchor? Yes. Can the safety railing be attached to the wing walls utilizing bolts rather then setting the posts into the concrete? No, the posts must be embedded in the wall. RFI 7: (1) There are no labor, material, or equipment costing done for the 4" perforated PVC pipe. 4” pvc is $1 per foot and the labor is $2 per foot. No equipment. (2) There are no labor, material, or equipment costing done for the 4" water-stop 4” water stop is $2.50 per foot materials and the labor is $6.50/foot (3) There are no labor, material, or equipment costing done for the 1-1/2" guardrail. The guardrail will be completed by a subcontractor at a cost of $17.65 per foot RFI 7: 1. 2. RFI 8: What is the curing time that the concrete will require prior to allowing water flow? Assume the concrete has additives that allow it to cure in 10 days. Flow may resume upon the 11th day if strengths are met. Will there need to be time scheduled for inspections from outside groups to comply with regulations such as the Dam Safety Act of 2006? As this is a high-profile project, the inspector will reside on the project. Assume no loss of time due to inspection issues. Our crews are the best and safest. What are the general weather conditions of the work site during the months of May-Nov? Approximately how many days of rain/snow could we expect each month? Does the location start to have hard freezes in that window which might hamper concrete work? Assume conditions are the same as the previous year when LCF completed the first dam on time. No weather impacts other than rain to hinder work. Project Addendum & Quote CEM 612 Construction Estimating Spring 2018 Are there issues with having crews work overtime? Do we need to schedule the work around weekends and holidays? If so, which holidays? Overtime is a fact of life in construction. It should be bid into the project as typical weeks run 50-60 hours. Remember, OT cuts into profits. Work will begin June 1 and finish on August 30. Final cleanup and establishment of vegetation must occur NLT September 15th to insure the Fall Harvest Party will go on as planned. RFI 8: There are grave concerns with the spillway design based on the provided estimated flow data. Essentially, any flow depth exceeding 2.0 feet over the completed spillway crest would overtop the dam with potentially damaging impacts to the spillway, the dam and the surrounding area. This leads to the following questions: 1. Is the provided flow data a maximum flow rate observed in a given month as opposed to an average flow rate? If so, over what time frame was the data collected, and what year over year variance was observed in the maximum flow rates? 2. Are modifications to the spillway design possible where the differential between the spillway crest and the top of the dam itself could be increased to 3.0’ which would allow flow rates up to 1600 CFS on the completed weir before overtopping (but no more the 500 CFS during construction) (based off weir flow calculator found at http://irrigation.wsu.edu/Content/Calculators/Water-Measurements/Rectangular-ContractedWeir.php)? 3. Is there an emergency spillway or other outflow for the reservoir located at an area outside the scope of this project that would prevent overtopping the dam at flow rates in excess of 904 CFS (the calculated maximum flow rate the current complete weir design can sustain before overtopping)? At this point in the project you must assume the calculations are correct. There is a similar dam a short distance upstream. The Feds have approved the design. I have seen designs questioned, and it is our right and obligation to do so. INSTRUCTOR NOTES: These are the items I came up with that are not addressed above. 1. Use delivered gravel cost from last years project. The pit agreed to hold their price. 2. Only use operator cost as the excavator is fully company owned and since the owner want the job he will not include the machine cost in the estimate. 3. No manual labor to clean rock. 4. Use taxes to figure costs on labor, but forget about unemployment and workers comp. 5. Figure same low sandbag height for both sides (second side will need to send water over new dam). 6. Rock anchor cost but not drilling costs assumes drill onsite for 1 day – need two days for phasing. 7. Crew labors only calculate foreman and 1 laborer when some require multiple laborers (sum vs. +..+) 8. Tool Trailer not included 9. No power or temporary facilities are included. 10. Using bank quantities for in place quantities, not a discrepancy in volumes from last project but attribute to varying site conditions. Project Addendum & Quote CEM 612 Construction Estimating Spring 2018 The final report should be as if you are presenting our estimate to the boss. Support your work. Walk him through the process. How are we going to build it. What will it cost? What are the issues? What is the cash flow? Since this is a dam project it will most likely be a lump sum bid, but the boss wants to see a detailed cost breakdown. Lastly put together a mock bid package, Bid, bond, insurance, recognize addendums, any other documentation that may be necessary on a fed job.
