City Engineer Director of Public Services MEMORANDUM TO: David Shea, Mayor ' s Administrative Aide FROM: Stanton Bigelow, P. E . , Director of Public Services DATE : January 23 , 1992 SUBJECT: Design Schedule and Considerations ; Bertram Field Track Reconstruction Project Ref : Meeting at your office of this afternoon ( 1-23-92 ) As a follow-up to our meeting of this afternoon, which was also attended by William Luster, City Planner and Dennis Daly, City Purchasing Agent, I have put together the following thoughts and the enclosed project schedule. 1) First, as the only licensed professional on staff, and under the Commonwealth' s Licensing and Municipal Engineering laws, I am the only person authorized by law to prepare/supervise the prepa- ration of engineering designs . Unless I am able to fully manage the design and construction project through to completion, I will be unable, in accordance with the Licensing laws, to affix my professional stamp and certifications to the plans or certify the completion of the work. Therefore, it would be appropriate for Luster to have Meridian contact me directly for specific instruc- tions and coordination, then only serve as a facilitator for the completion of our and the contractor' s work. 2 ) I seriously doubt the contention that it would take six ( 6) weeks to complete a design for this facility. That length of time is what it should take to completely prepare all of the contract documents , beginning with the first day of the survey services . The length of time estimated by Planning staff is most likely reflective of their lack of familiarity with complex ,geometric design formulas, which is certainly not the case with the Engi- neering Department staff . I have a COGO software package, Bench- mark, with which we can develop the geometric models and final grading plans and profiles, and an AutoCAD package with which we can rapidly convert those developed geometric models into design plans . 3 ) I want to be able to coordinate with Meridian from the start of their work, to insure that they satisfy our level of detail needs , establish a defined, closed and recoverable baseline and provide sufficient ties to it from site features, locate features we as designers consider important, and develop the working plan in a format that will facilitate our design efforts . Our early involvement during survey will familiarize all of us with the site and its environs, particularly important to making the design workable with a minimum of delays and changes upon review. 4 ) Other early design tasks that can proceed simultaneously with (or even be coordinated with) survey work include research of past design layouts/as-built drawings for Bertram Field; field location of buried utilities , including electrical conduits, signal condu- its, irrigation or service water piping and drain pipes/subdrain laterals ; marking of field-located buried utilities for notation by survey crew; development of geometric model templates (GMT) of finished track surfaces in AutoCAD; preliminary measurements of site areas available to establish basic design limitations; pre- sentation of alternative track operating plans at meeting with School Department staff; checking for wetlands issues, erosion control or drainage requirements, or other environmental issues; cheching for possible utility conflicts/limitations or other land-use issues; research of standard design/material specifications; preparation of draft general conditions , special general conditions and technical specifications; development of design document formats ( in AutoCAD and Lotus/Write-in) ; and pre- paration of itemized bidding format/preliminary engineer' s esti- mate of project cost . 5) Upon receipt of survey information, the surveyor' s data file can be imported to the already-prepared design document formats , compared with geometric model templates and an optimum design alternative selected. The selection of the optimum design is not a function of the aesthetics or operability of the plan, rather a function of the engineering requirements of the site. The selec- ted design template can then be registered over the existing con- ditions plan, and final design grades can be established. Cross- sections should be prepared at ten ( 10 ' ) foot intervals, showing proposed and existing grades, utilities crossings and track construction sections . Site appurtenances such as the pole vault runway, planting box and pit, hig jump take-off and landing pit, shot put circle, discus area and sprint out-run area/protective barrier, should be detailed and located on the site plan. A sepa- rate site plan should be prepared showing all lane/start line markings for all running events . 6 ) Final design tasks should include review of design plans with School Department staff, Mayor' s Office/City Planner, editing and final design checking of contract documents , plan certification, printing and production of copies of project bidding documents, and assistance to Purchasing Agent during bidding phase (pre-bid conference, preparation of any technical addenda, canvass of item- ized bids from bidders ) . 7 ) The encl'osed schedule reflects a running start ON MONDAY, JAN- UARY 27 , 1992 , and no delays or additional work requirements being added during the design phase. To the extent that I can partici- pate in the design, I will ( I will make myself exclusively availa- ble during the next 10 days , while coordination of Meridian ' s and our design efforts is needed) . I would ask that Juli Reimen- schneider be made available to work for me on this project on a full-time basis , as I will make our entire Engineering Department ( Rich and Bob) available. Also, during construction, I would like to have Willy Beaulieu made available to me to clerk the project, reporting to me so that I may maintain regular control of the con- tractor' s activities . Otherwise, I would not be able to certify the construction as being in conformance with my certified design. 8) This schedule represents the best-case scenario, and has the construction being done from April 1 through May 15, 1992 . During that period, weather will be a minimal problem, particularly with respect to availability of materials and their placement/curing. Again, I reiterate that if any additional work tasks arise during the design (permitting requirements not noted herein, special site conditions, unusual design or construction details) , this will result in slippage of the final date of completion. cc: R.

Install approximately 660 square feet of new bituminous concrete pavement . New pavement shall conform to Section 02513 of the Middle School West Specifications, and shall meet existing pavement in line and grade. Transition between proposed and existing shall be even and flush. EXISTING BITUMINOUS CONCRETE PAVEMENT: Existing pavement shall be saw cut at edge of proposed slab. Finish course of existing pavement shall be ramped up at the upper ( side closest to the gate) side of the slab. Bituminous concrete shall meet this edge of the slab flush. Transitions shall be smooth and even. ELECTRICAL TRENCH: It is the contractor ' s responsibility to notify Dig Safe and to check project drawings to locate any underground utilities prior to conducting the additional excavation required for extending the electrical conduit . Excavation for electrical trench shall conform to section 02200 of the Middle School West Specification. Trench dimensions and backfill shall meet the City Electrician ' s standards . ELECTRICAL HOOK-UP: Electrical service shall meet the City Electrician ' s requirements . Further Specifications shall be provided. CHAIN LINK FENCE: Approximately 100 lineal feet of chain link fence shall be removed. Relocated or new fence (approximately 75 lineal feet ) shall be installed where shown on the plan. Fence in the new location shall conform to the details and Section 02832 of the Middle School West specification, and shall be the same as what presently exists in this location. Appropriate grading of the fence relocation area shall be conducted prior to installing the fence. Grading shall result in a smooth level area on which the fence will be located. A smooth transition shall be made so that there is no ridge which could block water from flowing toward the field. CONCRETE SLAB: It is the contractor ' s responsibility to notify Dig Safe and to check project drawings to locate any underground utilities prior to doing any excavation . Excavation for the slab shall be conducted to the extent shown on the detail . Six inches of crushed stone compacted to 95% standard proctor density shall be placed below the slab. If a condition exists where there is not six inches between the bottom of the slab and the ledge the slab may be tied into the ledge. The landscape architect shall approve the number and extent of the tie ins, and shall determine whether other accommodations can be made to avoid ledge removal . Concrete shall be 4000 psi with #4 rebar placed 12" on center in both directions . Concrete and reinforcing bars shall meet section 02515 of the Middle School West Specification. Slab dimensions shall be as shown on the detail . Finish shall be broom finish with two inch troweled edges, at edges of slab and at expansion joint . Expansion joints shall be as called for in the concrete pavement section, 02515 of the Middle School West specification. MEMO RE: Relocation of Concession Stand at Bertram Field FROM: Juli Riemenschneider DATE: November 5, 1992 Please review the attached plan. The following is a summary of what has to be done to accomplish the relocation: 1. The existing pavement has to be saw cut to the size of the concession stand. 2 . This area has to excavated to a depth of 3 feet minimum. The depth of bedrock is approximately six inches below the existing grades, so bedrock removal should be anticipated. 3 . A 4000 psi concrete slab has to be constructed. 4 . The underground electrical service has to be continued to the new slab location. 5. The fence has to be relocated. 6 . A new bituminous concrete area has to be constructed between the proposed slab and the new fence and ledge. 7 . A small area of bituminous pavement has to be ramped up to meet the slab. Please note the concrete slab will be level, and will be constructed at the existing elevation of the highest corner. At the low side, the slab will protrude up to 1 '-4" above existing grade, this will mean that the windows of the concession stand will be higher from the ground. As presently proposed the door of the concession stand will be closest to the gate. This will allow a truck to back it onto the slab, and allows the shortest distance for the electrical service. Please get back to me if you have any comments on this plan. I will begin more detailed plans at the end of next week. Bertram Field Survey INS. RAL Nov. 5, 1992 ROD JR F.S.. H.I. ELEV.

EXT. 31 1 'aF FAX(508)744-5918 umn, TO: Stan Bigelow Rich Lis Bob Geswell Larry McIntire Willy Beaulieu FROM: William Luster , City Planner RE: Track Design Issues DATE: January 28 , 1992 To facilitate the incorporation of many of the concerns of people I have been working with on this project up to now, and some of my own, I have prepared the following list . Most of these items are touched upon at the January 27 , 1992 design meeting . If there were other concerns not included or any inaccuracies which will influence the design, please let me, Rich or Stan know. Having a working check list will helps us during the design process . Thank you. Site Design Issues : The track should be as long as possible, even if it turns out to be an uneven increment . People in route to the visitors stand should not have to walk over the track and field, this is particularly unfeasible during a football game. The track should be partially or completely fenced in, to prevent people from walking on the track during a football game. Incorporation of paved walking paths to both sets of stands should be included in this design, or allowances for such should be made so that they can be built in the future. Long jumps, triple jump, and high jump runways and landing areas should be located in the semi-circular areas between the track and football/soccer field. This probably will not be possible, the next best location is the north side of the practice field. The field area inside the track should be widened to as close as possible to 65 yards to accommodate a soccer field. The track straight-a-way should be located on the visitor stand side of the track . Ideally the straight-a-way should be seven lanes , six lanes will be acceptable. Four lanes will be acceptable for the other portions of the track . There should be an area at the north end of the straight-a-way for runners to slow down. A minimum of two feet of paved area should be left between the outside of the outside lane and the concrete wall at the base of the grandstand. It is my suggestion that, an interceptor drain run along the entire inside perimeter of the track . The concession stand should be relocated either in ' this contract or in the Middle School West contract . The score board may need to be relocated to allow room to enlarge the track . Relocation, or installation of a new score board should be planned. If budget does not permit the work to be done now, we should be sure future installation of conduit will not disturb the track . The irrigation controls will need to be relocated. Drain inlets where the existing field house may need to be relocated. Investigation of bed rock material below proposed track expansion should take place, prior to bid document completion, to determine whether blasting will be necessary. I have noticed that the area north of the track , below the rock ledge is wet. Drainage alternatives for this area should be addressed. Criteria for Track Design: The following standards were taken from the Track Construction Manual published by the National Federation of State High School Associations, and the Tennis Court and Track builders Association, copyrighted 1983. If anyone can get a copy of this it is an excellent reference. The measuring line for a lane is defined as 20 cm from the inside of the painted line of each lane. Lanes should be 1 . 067 meters or 42 inches wide. The track should be a continuous elevation along the inside edge and should slope up from this point at 1% .
