Engineering Research and Development

Until the fall of 1997 the engineering assignments undertaken by Mr. Eckman were design oriented.  Most followed standard engineering practice and procedure and contained little room for added research and development.  After years of repetition he started to wonder where some of the guidelines and traditional methods came from.  Who creates the rules and regulations that have become standard practice?  Do they result in the best possible designs?  Are established computer programs and model techniques used every day by engineers correct?  As a result of these questions, along with others, Mr. Eckman decided to pursue a graduate degree that studied the performance of NHDES designed stormwater control systems.  This research project is described below along with others that he has had the opportunity to investigate.  The major research and development projects are summarized below.

Ø      Assessment of the performance of permanent stormwater control systems with respect to water quality. 

To investigate this objective nine stormwater control systems were selected for study.  They were divided into categories that include swales, detention (dry) ponds, and retention (wet) ponds.  Samples of storm water were then extracted from the inlet and outlet of the systems and tested for  a variety of water quality analytes.  Non-parametric analysis of the  preliminary results indicated that in many cases contaminant analytes increase in concentration as they pass through the system.  Final conclusions are still in progress and will ultimately be used to develop improved stormwater control systems.      

Ø      Comparison of the type III storm distribution with actual measured storm distributions.

To complete hydrologic investigations using NRCS (formerly SCS) methodology a generic storm distributions is applied.  In southern New Hampshire a type III distribution is the one specified.  By field measuring hydrographs and storm patters at individual sites a comparison could be made.  Preliminary results show a significant difference and the data is being investigated for divergence trends.  If divergence trends are determined to be statistically significant further investigation could lead to the development of a more regional storm type distribution.        

Ø      Investigation of sediment contamination at the entrance and exit of stormwater systems.

Grab samples of sediment were extracted adjacent to the inlet and outlet areas of the stormwater control systems under investigation.  This was done in an effort to determine trends as to where contaminants end up when they are removed from stormwater.  Preliminary data indicate significant contaminants sorb to sediments and when inlet and outlet contamination levels are compared the results is higher contaminant loads near the inlet.      

Ø      Investigation of vertical migration of contamination into groundwater below stormwater systems.

Mini-piezometers were installed adjacent to the inlet, outlet, and at an ambient location around each stormwater control system.  To determine vertical migration gradients, water surface elevations were measures in the wells frequently for an extended period of time. In many cases the sediment on the bottom of the system was restrictive creating a significant gradient. Through use of these wells an estimate of hydraulic conductivity was also determined beneath each system.  Samples were taken from each well and contaminant analytes measured. This was done in an effort to determine trends as to where contaminants end up when they are removed from stormwater.  Although further analysis is underway preliminary results indicate that groundwater below the systems’ does not show elevated dissolved contamination.  It appears most contaminants are sorbed to sediments, vegetation, or simply pass through the system suspended within the stormwater.   

Ø      Spruce hole peat bog hydraulic conductivity depth profile

The Spruce Hole Aquifer is located in Durham and Lee, New Hampshire.  At the center of the aquifer is a unique and environmentally sensitive kettle bog formation created by the melting of a glacier.  This area is called the Spruce Hole Peat Bog.  With growing consideration toward extracting water from the overall aquifer, for use as municipal a water supply, the impact on the Spruce Hole Peat Bog was of interest.  Mr. Eckman completed slug tests to determine hydraulic conductivity values beginning at a shallow depth and extending approximately 60 feet below the bog.  This was accomplished by installing mini-piezometers screened at different elevations descending into the peat below the bog.  The results as published by Professor Thomas P. Ballestero, PE indicate that the environmentally sensitive Spruce Hole Peat Bog is a perched wetland and not controlled by the larger Spruce Hole Aquifer. 

Ø      Field measured outfall dilution as compared to the CORMIX computer predicted dilution

To complete this project both the Durham and Dover, New Hampshire wastewater treatment facility outfalls were selected as investigation sites.  The CORMIX computer model is suggested by regulatory agencies and is a standard in the outfall design process.  The investigation attempts to verify the accuracy of the CORMIX model and determine if how precise a calibration is possible.

In completion of this project Mr. Eckman designed and fabricated a system that enabled precise sampling from the water column adjacent to the existing outfalls.  It incorporated an anchor on the ocean floor and a segmental rod with sampling ports as close as 6-inches on center.  The system functioned properly in currents up to 4 feet-per-second with depths reaching 23-feet.  Through use of this sampling system field dilution values were determined for both investigation sites.  The CORMIX modeling process is still underway and no preliminary results are yet available.

Ø      July 1996 to July 1998, Secretary of the New Hampshire Society of Professional Engineers (NHSPE) Board of Directors

Ø      July 1998 to Present, Treasurer of the NHSPE Board of Directors

Ø      Fall 1998 to Present, Initiated the NHSPE.org Web Page collecting content, photographing events, and creating text captions. Oversaw updates and design direction of the site.

Ø      Since the initiation the NHSPE/ASCE sponsored Engineers Week Mall Display, Mr Eckman has participated by transporting exhibits from the University of New Hampshire, soliciting student assistants, and helping to staff the exhibit.  He believes it is a great opportunity to introduce young children, elementary and high school students to the profession of engineering as a possible career.  In addition it informs the public as to what engineers do that may not be available to them otherwise.      

Ø      Recognizing student interest in real world engineering projects, Mr. Eckman solicited two engineers from the NHSPE Board of Directors, to speak at UNH.  The first was Woodbury Fogg, P.E., Director of the Office of Emergency Management for the State of NH, who spoke in the spring of 1997 about becoming a licensed Professional Engineer and discussed some engineering projects he has completed.  The second was David W. Gates, P.E., Chief Engineer, CLD Engineering, who spoke in the spring 1999 providing a slide show of the South Willow Street and Mall of New Hampshire rehabilitation.  

Ø      Mr. Eckman is Seacoast coordinator of MATHCOUNTS and has filled the position since the fall of 1998. His responsibilities are to establish dates for the event, assist schools with registration, order awards, order exams, reserve an exam room, organize refreshments, proctor exams, complete grading, and provide both certificates and trophies to the individual and team winners.  For background MATHCOUNTS is a junior high math competition that pairs students from NH high schools in both a team and individual events.  This event is sponsored by the NHSPE and has the goal of providing students incentives to excel in science and mathematics.  Certificates are provided to all team members and coaches along with trophies to the top finishers in each event.  The ultimate prize is a trip to Washinton DC for the group that wins the opportunity to represent the state of NH in the national competition.            

Ø      Mr. Eckman has assisted numerous students with the transition from college to work in the engineering profession.  Through encouragement of student participate in state engineering society events and activities many have begun the networking that has lead to their employment.  Mr. Eckman has reviewed resumes and provided both written and verbal references for worthy engineering graduates.

Ø      Wells National Estuarine Research Reserve:  Mr. Eckman helped them get set up to monitor energy losses in tidal flows passing through a manmade constriction at the entrance to a saltwater marsh.  The staff at the research reserve had not completed such an analysis and required a few days of engineering assistance to enable them to complete it.    

Ø      Manchester and Dover NH Soup Kitchens:  Mr. Eckman has volunteered to assist with serving and meal preparation at both the Manchester and Dover, NH Soup Kitchens.  This was done in Manchester while affiliated with CLD Engineers and in Dover while affiliated with the Civil Engineering Department at the University of New Hampshire.   

Ø      Tutoring:  Mr. Eckman has on numerous occasions spent substantial time tutoring high school and college students with math and engineering.  He believes that sometimes the difference between success and failure for a student is a little help with understanding what problems are asking, and what the real world applications are.  

Ø      Pro Bono Consulting:  Mr. Eckman although not in the habit of providing no cost engineering services, has made a few exceptions.  He designed a septic system at no cost to a family that was facing temporary unemployment and had few resources.  On another occasion he designed a mechanically stabilized earth retaining wall on an emergency basis to protect a house from possible structural damage.  The family who owned the house was under financial stress after borrowing to pay for construction costs and the engineering bill was waived.

Ø      New Hampshire NPS Management Plan:  - In August of 1999, Mr. Eckman was asked to review and comment on the draft copy of chapter 3 and chapter 7 of the New Hampshire Non-point Source Management Plan, by Dr. Tom Ballestero, an NPs partner for the State of NHDES.  Chapter 3 addressed urban runoff and chapter 7 construction activities.  The final report was published in November of 1999 and provides guidelines for protection against non-point source pollution. 

Ø      Bunker and Johnson Creek Hydraulic Analysis:  - Mr. Eckman was retained as a consultant engineer by Dr. Thomas P. Ballestero, PE of the University of New Hampshire to work on a hydraulic analysis of Bunker and Johnson Creek located in Durham, New Hampshire.  Both of these creeks had an 8-foot tidal cycle and therefore experienced flow from both directions.  In completion of this project Mr. Eckman installed monitoring equipment and measured elevation and velocity for several days of tidal cycles.  From the field data he computed energy losses and corresponding flows through each structure during several tidal cycles.  A friction coefficient was then computed and applied to peak river flows during a 100-year and 500 -year storm events, superimposed on peak tide events of similar frequency.  This analysis was used to establish hydraulic opening size requirements for proposed NHDOT bridges proposed over both Johnson and Bunker creek.  

Ø      Hannah Dustin Bridge:  - On behalf of Hansen Construction, Ltd. Mr. Eckman designed the method and means to remove the Hannah Dustin Bridge over the Merrimack River in Canterbury, New Hampshire.  Approximately 50% of the bridge had remained since partial demolition took place in the 1960’s and with liability concerns over injuries to swimmers jumping off the bridge, the State of NH decided to remove it.  After investigation into several alternatives the final solution was to remove the deck and approach, pull the bridge off the river pier, lift the shore side off the pier, pull the bridge on shore, and cut it up section by section.  These method and means were developed based upon optimum safety, minimized environmental impacts, efficiency, and economic feasibility. After this procedural method and means was designed, Mr. Eckman solicited the assistance of structural engineering professors, in the Civil Engineering Department at the University of New Hampshire, to complete the complex structural analysis required.  The method served the project well and it was completed under budget and on schedule.  Below in figures 1, 2 and 3 are photographs of the implemented demolition sequence.

Figure 2 – Bridge lifted off shore abutment

 

Figure 3 – Bridge being pulled onto shore

Ø      Patterson Hill Road Bridge:  - On behalf of Hansen Construction, Ltd. Mr. Eckman designed the method and means to complete the Patterson Hill Road Bridge rehabilitation project over the Contoocook River in Henniker, NH.  The objective was to temporarily support the superstructure while replacing the bottom truss chords and deck support system.   Anticipated and as permitted in the wetlands permit plan was a system that placed twelve support columns and bases within the Contoocook River.  For environmental protection reasons and because of major structural disadvantages, this option was not selected.  Mr. Eckman designed a method to support each truss individually while the deck and transverse bracing were removed from the structure.  Then through use of a crane and lifting spreader beam, each individual truss was removed and placed horizontally on the shore for rehabilitation.  Worker safety reduced environmental impacts, reduced construction impacts, protection of the remaining historic structure, and the method of producing the highest quality final product were the controls that lead to selection of this method.  JSN Engineers of Portsmouth, New Hampshire was retained to complete the final structural analysis and design following approval of the proposed method and means.  Below in Figures 4 and 5 are photographs of the implemented method and means.

BACKGROUND

Between 1984 to 1986 Mr. Eckman worked summers, weekends and vacations for a licensed land surveyor and also an excavation contractor.  It was during this period of time that he discovered the profession of Civil Engineering.  Excited about the profession he followed the Surveyor’s advice (to get hands on training first) and went to Vermont Technical College were he graduated with an Associates Degree in Civil Engineering Technology.  In the spring of 1988, for personal reasons, he opted to discontinue full time pursuit of a BSCE degree and took full time employment with CLD Engineering, Inc. in Manchester, NH.  This was the beginning of his engineering experience and part time completion of BSCE degree.      

GENERAL~ ENGINEERING EMPLOYMENT TIME LINE

EXPERIENCE

Mr. Eckman is a Civil Engineer that has site development, highway, and bridge design experience.   The thread that binds his seemingly general experience together is a focused interest in water, soil and their interaction.  On virtually all projects he has completed there was grading, hydraulic, hydrologic, and erosion protection designs required.  Attached is a listing of representative projects that detail the types of work he has completed over the years. 

SUMMARY OF ENGINEERING EXPERIENCE

ENGAGEMENT #1

Employer:  CLD Engineers:                             

Project:  Country Side Village

Client:  Rick Rust III, (Developer)                                             

In the northwest portion of Manchester, this multiphase project encompasses 490 acres of property.  A conceptual master plan created in December of 1989 indicated that the project would ultimately be developed to contain over 3,000 dwelling units.  Each phase of the project represented significant work experience.  My responsibilities are outlined below as specific to phases of the project. 

·                    Countryside Village Residential Subdivision - PAPP Parcel (December 1988 - February 1989

One of my initial assignments at CLD was the conceptual design of a residential subdivision on a portion of the site known as the PAPP parcel.  Design criteria was outlined in the City of Manchester’s Subdivision Rules and Regulations.  Following these criteria I designed over 500 residential lots including access drives with both horizontal and vertical geometry.  My design was presented to the client and with few revisions met with his approval.  Permitting and construction of this portion of the project was scheduled to take place at a later phase. 

·                    Countryside Village Hillcrest Terrace Retirement Community (February 1989 - May 1989)

Although residing on the Countryside Village property the Client for this project was Catholic Medical Center (CMC) of Manchester, NH.  The project included site design for a 214 unit elderly home which resided on a 17.7 acre lot.

As a large fast paced project it took a combined work effort to complete.  I designed building locations, entrance drives and parking locations.  I graded the site including alternate options and designed closed system drainage. I prepared red line markups and back checked the mark ups upon completion by the drafting department.

I checked sewer design computations for average daily flow and pipe capacity for peak hour flow including infiltration.  I designed all sewer manhole structure locations and inverts and checked to avoid conflicts. 

Drainage design was done using the Modified Rational Method in combination with a computer program to model routing through the detention pond.  I computed all watershed characteristics and boundaries.  I graded the detention pond area and utilized computer software to calculate pre- and post-development conditions.  Hillcrest terrace is currently constructed and occupied.

·                    Countryside Village Phase 3A Apartment Units (June 1989 - September 1989)

This phase of development consisted of site design for a 28.7 acre parcel.  Proposed on this site were buildings which would ultimately contain 252 units.

I was assigned to this project and responsible for most tasks required for design.  I designed building locations, parking areas and entrance drive locations.  I completed grading, drainage, sewer and utility design.  I prepared red line mark-ups of design and was responsible to back check drafted plans.  I prepared computations for drainage and sewer design.

I completed drainage design by using the Modified Rational Method utilizing a Civil-soft program called OTTHYMO to complete routing analysis through the detention pond.  I computed watershed characteristics, sized detention pond storage and completed analysis for 10-year and 50-year storms.  On-site drainage structure analysis was completed using Rational Method for a 10-year storm event consistent with NHDOT procedures.  

Proposed culverts under an adjacent street were designed and sized to convey flow for a 50-year storm event and were analyzed for both inlet and outlet control.  On-site ditches were designed and sized for 10-year storms.  Rip-rap was sized and proposed at outlets and ditches where velocities exceeded allowable limitations.  These technical computations were organized for placement in the drainage report.  Project status was on hold in 1992 and is not known to me at this time.

·                    Countryside Village Phase 5, Countryside Boulevard Extension (December 1989 - January 1990)

To provide access to the next phase of Countryside Village a 500 LF extension of the entrance roadway was required.  This roadway would be dedicated to the City of Manchester, New Hampshire and was designed to city street standards.  The roadway had embankments of over 20 feet and included an 8’ x 8’ box culvert to convey a stream through it. 

As an assistant engineer assigned to the project I was involved with most aspects of the design.  I designed typical sections, horizontal and vertical alignments, utility locations, right-of-way and utility easements.  To provide construction access to the already approved Hillcrest Terrace phase, bid documents were required quickly.  It was proposed to provide a temporary vertical profile below the final design grade with a gravel surface to expedite access by construction vehicles.  I designed this vertical alignment, computed quantities, and assisted in preparation of specifications.  This project has been constructed and is in use today.

·                    Countryside Village - Water Booster Station (900 Units) (December 1989 - February 1990)

Water distribution systems owned by the Manchester Waterworks and the University of New Hampshire-Manchester served the Countryside Village Development at this time.  These distribution systems served 448 apartment units already constructed on-site.  As conditionally agreed to any expansion beyond 450± units would require the developer of Countryside Village to construct a water distribution system.  CLD was contracted to prepare a design for this expanded distribution system as future phases were planned.

My responsibilities included computation of design flows for domestic and fire services.  I also prepared coordinates with elevations at hydrants and other points of interest.  To complete the analysis I used software called Civilsoft Water to model the distribution system.  I then iterated the analysis to investigate alternatives and provide an efficient design.  I assisted in the selection of pumps, preparation of construction documents, and establishment of pumping system performance envelopes.  The project has been constructed and now serves Countryside Village residents. 

ENGAGEMENT #2

Employer:  CLD Engineers                             

Project:  Reviews                                                         

Client:  Derry, NH/Epping, NH Planning Boards

When projects were proposed within the Town of Derry or the town of Epping, CLD Engineering completed a technical review of these projects.  As an Engineer’s Assistant I would review the project for the licensed engineer responsible.  This would generally involve around one half day of my time and would focus on drainage computations, site grading, erosion control measures, and general town requirements.  The number of these reviews varied and occurred about twice per month.  From this review experience I was exposed to different methodologies applied by other engineers and companies.  I consider this experience to be important to my professional development and have included it.

I developed a method to check the plans efficiently and covered critical areas summarizing my results for the responsible engineer.  Key points evaluated with respect to drainage were equivalent pre- and post-development watershed areas, reasonable curve numbers or Cn values, correct design storm(s), and verification that subcatchments were added correctly to obtain balanced flows.  Adequate pipe sizing was also checked based on use of NHDOT nomographs. 

ENGAGEMENT #3

Employer:  CLD Engineers                                                       

Project:  Shutes Corner                                          

Client:  Town of Derry, NH                                                        

This was an intersection reconstruction and widening project required due to dangerous existing conditions.  I designed horizontal alignments that were complex due to the intersecting curved roadways and lane tapers.  A traffic engineer provided stacking requirements and I applied these to design of the alignment.  I designed vertical alignments, cross-sections, prepared super-elevation calculations in the curved approaches and also designed an intersection grading plan.

As part of this project, I attended a Public Hearing in Derry, New Hampshire to answer technical questions from owners of abutting properties with respect to impacts.

ENGAGEMENT #4

Employer:  CLD Engineers                  

Project:  Keller Street Improvements        

Client: Carpionato (Developer)                                                  

This project involved a 1,600 LF extension of Keller Street to a connection with Auto Center Road in Manchester, New Hampshire.  Since this road would be dedicated to the City of Manchester it was designed to City Street Standards.

I designed the vertical alignments and typical sections for the project.  I designed grading for the roadway and designed each cross section.  I computed drainage structure inverts and designed a 1,011 LF water line which was located in the roadway.  I prepared mark-ups for drafting and back checked them upon completion.

ENGAGEMENT #5

Employer:  CLD Engineers      

Project:  Stonehedge Site Plans

Client:  Unknown                                                                            

This project consisted of site design for a 13.3 acre commercial development.  A 3-story 98,000 sf office building was proposed on-site with associated drives and parking.

As an Engineer’s Assistant on this project I was responsible for a variety of tasks.  I computed watershed characteristics and associated input data for a TR-55 analysis of the 72 acre drainage basin.  I designed domestic and fire water services to the building and assisted with a large on-site septic system design.  I was responsible to prepare and back check drafting mark-ups for the full set of approval drawings.

ENGAGEMENT #6

Employer:  CLD Engineers        

Project:  Souhegan High School

This project was adjacent to the existing Amherst Middle School and involved construction of a new high school on a parcel over 30 acres in size.  Tom Summers, P.E. the Vice President of CLD was a resident of Amherst and for the majority of the project worked directly with me.  I was responsible for the site approval package including creation of mark-ups and back checking.

I designed the location of the building, drives, parking areas, and 12 proposed athletic fields.  I used state requirements to establish the official size of all the athletic fields and overlapped them as seasonally possible.  I designed all horizontal and vertical geometry and graded the entire site.  I designed drainage, utility locations, and assisted with a septic system design.  During the duration of the approval process I was responsible to coordinate all comments from town committees and the architect.

ENGAGEMENT #7

Employer:  CLD Engineers

Project:  Lamarre Concrete Site Plans

Client:  Lamarre Concrete                                                    

Location:  Greenville, New Hampshire

This project consisted of site design for an 8 acre commercial project.  My responsibilities included design of building locations, parking lots, and access roadways.  Many alternate designs were completed to conform to the client’s wishes.  I prepared input data for an SCS TR-55 drainage analysis of the 150 acre runoff basin upstream of the site.  This included field visits to analyze existing conditions and establish watershed boundary locations.  This information was used by another engineer to design a box culvert on-site as well as analyze downstream culverts crossing NH Route 31 in Greenville, New Hampshire.

ENGAGEMENT #8

Employer:  CLD Engineers

Projects:  Seven Bridge Replacement Projects

Client:  Vermont Agency of Transportation

Due to fewer site development projects anticipated CLD began to involve me in highway/bridge projects.  The goal was to utilize site development experience I had with respect to roadway design.  Although these were bridge replacement projects, my involvement was primarily highway design with only limited structural involvement. 

                                                                                                                                                            As an Engineer’s Assistant on these projects I was given assigned tasks with respect to design.  Tasks included design of horizontal and vertical alignments including various options for each project.  I computed super-elevation and stopping site distances.  I designed critical cross-sections, determined guardrail limits and designed intersections.  These projects were in their early stages and iterations were performed to evaluate design alternatives.  The following details the general scope of each project:

·                    Braintree, Vermont - Route 12A (0.26 mile Highway Approach) – Involved the realignment of a dangerous reverse curve on an otherwise straight portion of road.

·                    Cambridge, Vermont - Route 108 (0.25 mile Highway Approach) – Involved the evaluation of 2 alternate alignments approximately 1,000 feet apart.  One alignment was close to the existing while the other was upstream and would connect into Vermont Route 15 forming a new intersection.

·                    Jamaica, Vermont - Route 100 (1,400 LF Highway Approach) – Involved the realignment of the roadway to fit as close to the existing bridge as possible, in order to maintain traffic during the construction phase.

·                    Warren, Vermont - Route 100 (0.25 mile Highway Approach) - Provided a safe geometric design while minimizing costs and social impacts.

·                    Johnson, Vermont - Route 15 (0.25 mile Highway Approach) – Involved a bridge replacement project that had to be constructed in phases.  In addition, a partial detour and a traffic control plan were required.

·                    Pownal, Vermont - Route 346 (0.25 mile Highway Approach) – Involved realignment to provide a safer geometric design which eliminated existing reverse curves.  The project required phased construction.

·                    Royalton, Vermont - Route 14 (0.25 mile Highway Approach) - Provided a temporary bridge with detour approach roadway that maintained traffic while the replacement bridge was constructed.

ENGAGEMENT #9

Employer:  BA&C Engineers

Project: Four Bridge Replacement Projects

Client:  Vermont Agency of Transportation

These projects involved the replacement or rehabilitation of four bridges in the Town of Barre, Vermont.  As part of the VAOT Town Highway Bridge Program, Bettigole, Andrews and Clark (BA & C Engineers) was contracted to complete inspections, structural studies, highway and bridge designs, utility designs, and cost estimates.  My involvement with these projects was in the initial alignment and structure type study phase.

I was given a variety of tasks with respect to completion of design for these projects.  Tasks included design of horizontal alignments, vertical alignments, intersections, closed system drainage and typical sections.  In addition, I evaluated critical cross sections, computed quantities and prepared cost estimates.  Of importance is the fact that for each project up to four alignment options and four structure types were investigated.  I completed on-site inspections and limited field surveys of the projects including both taping and transit work.  With VAOT surveys and BA&C inspection data I designed longitudinal sections, elevations, and general plans for each bridge.  The following details the general scope of each project:

·                    Parkside Terrace Bridge BRO 1446(19) -(900’ Highway Approach/ 100’ Span) – Motivated by a proposed elementary school on a public park parcel owned by the Town of Barre, VT this project proceeded quickly.  Realignment and complete replacement of steep approach grades to an existing bridge, which was closed in winter due to an inability to support snow plows, was required.

·                    Granite Street Bridge HDP 9281(1)- (300’ Highway Approach / 120’ Span) – Rehabilitation of the existing 1928 structure was required due to extreme deterioration of the superstructure.  Once closed, the bridge had been reopened after the VAOT constructed a temporary Baily bridge to convey a single lane of traffic. The temporary condition was less than ideal and the project was a high priority.

·                    Willey Street Bridge BRZ 1446(17) (800’ Highway Approach / 75’ Span) – Existing structure was both functionally deficient due to a narrow (20’) width and structurally deficient due to deterioration.  Realignment of the roadway was difficult due to the close proximity of a three- way intersection to the bridge.

·                    Blackwell Street Bridge BRM 6000(13) (300 feet Highway Approach / 80’ Span) -  The existing bridge had steel superstructure constructed in 1955 which had experienced significant deterioration due to an open grid deck.  Supporting substructure was combined granite block and concrete where the initial construction date was unknown

ENGAGEMENT #10

Employer:  BA&C Engineers

Project: 5 bridge Projects

Client:  NHDOT

·                    I-93 NB & SB over Pemigewasset River, Holderness-Plymouth, NH – Rehabilitation design of twin 3-span (130’-160’-130’) continuous interstate bridges.  Widening of existing decks, abutments, and piers was required to accommodate new roadway alignments and ramps.

I designed abutment, deck and fascia reinforcement layout, masonry details, bridge rail spacing, and proposed pier extension interface with existing pier.  I computed abutment bridge seat elevations and  a grid of deck elevations as requested by the contractor during construction.  I calculated both concrete and reinforcement quantities for use in cost estimates. 

·                    I-93 NB, SB, & Ramp over NH Railroad, Plymouth, NH - Rehabilitation design of three, 3-span continuous bridges.  Widening of existing decks, abutments, and piers was required to accommodate new roadway alignments and ramps.

I designed deck and fascia reinforcement layout for all three bridges, two of which were radial decks that added complexity.  I designed masonry details, bridge rail spacing, computed abutment bridge seat elevations, and a grid of deck elevations as requested by the contractor during construction.  I calculated concrete and reinforcement quantities for use in cost estimates for all three projects. 

ENGAGEMENT #11

Employer:  BA&C Engineers  

Project: Stoddard Box Culvert                           

Client:  New Hampshire Dept. of Transportation                    

Construction of NH Route 9 over Little Granite Lake outlet was completed using a 100’ cast-in-place concrete box culvert.  This project was designed in conjunction with realignment of NH Route 9.  Special design features included fish weirs, an outlet dissipation pool and a walkway through the culvert.   

I designed reinforcement layout for the project, masonry details, a longitudinal section, a general plan, and elevation. I calculated concrete and reinforcement quantities for use in cost estimates. 

ENGAGEMENT #12

Employer:  BA&C Engineers

Project: Avon, Maine                                                               

Client:  Maine Dept. of Transportation                                    

This project involved redesign for 3 miles of rural route 4 highway along the sandy river in Avon, Maine.  As a sizable project several engineers and technicians were involved with the project.   

I designed typical sections, vertical profiles, and evaluated critical sections including those along the Sandy river.  I prepared a procedure to efficiently import MDOT cross section survey data into the computer on an MDOT format sheet with a proposed template.  This procedure included customized programming and when complete was applied by BA&C technicians to prepare over three miles of cross sections.

Project:  Shaw’s                                                                 

Client:  Desco Associates

As my first assignment at Appledore I was supervised closely and given only specific design tasks to complete.  Shaw’s engineering standards were completely new to me as were the specifics of Appledore’s methods and procedures.  Excited with the magnitude of the project and the challenge of a new job I worked extremely hard to get up to speed.  Shaw’s Bristol required a complete site design along with roadway relocation of a portion of Lewis Street.  Completion of the overall project was done as two separate smaller projects which are detailed below.

·                    Lewis Street Relocation – A dangerous four-way intersection existed where Lewis Street intersected Lewis Road and Concord Street.  By removing the skewed Lewis Street leg of the intersection it provided for a safer three-way intersection.  Further, by discontinuing a portion of Lewis Street a larger developable parcel suitable for a Shaw’s would be created. The removed intersection leg would be relocated perpendicular to Lewis road which created a safe 3-way intersection.  Relocation of all utilities within the discontinued portion of Lewis Street was required along with construction/reconstruction of 1,500’ of roadway.   

I designed pavement markings, signage, typical sections, sewer and drainage structure location and inverts.  I completed quantity estimates including earthwork and assisted with horizontal and vertical alignment design.      

·                    Shaw’s, Bristol, Connecticut – The site Project consisted of construction of a 62,000 SF Supermarket with accompanying access drives, parking areas, drainage infrastructure, utility connections, lighting, and landscaping.  Space was limited on the 8 acre site and retaining walls were required along with pedestrian stairways.    

 I designed the location of the building, drives, parking spaces, grading, and retaining walls.  The computations I prepared for the cast-in-place retaining walls were superceded when the contractor substituted a pre-cast-concrete segmental retaining wall system.  I computed drainage watershed areas and longest flow path for use with pre/ post-development computations and drainage structure analysis.  I designed site lighting to meet minimum and maximum requirements specified by Shaw’s criteria and designed roadway entrances and exits to provide adequate turning movement for a WB60 design vehicle.
