For 37 yrs LAW, Inc has shined in the more difficult jobs…the jobs no one else wants to deal with. One such project was the Dorrs Dam rebuild in Manchester, NH. It showcased new technology (equipment) meshing with one of man’s oldest techniques (siphoning water) in some very non-conducive conditions.
Dorrs Pond Dam
The meeting of modern and old technology.[img src=http://newhampshiresitework.com/leightonawhite/wp-content/flagallery/dorrs-pond-dam/thumbs/thumbs_overview-of-dam-reconstruction-using-recycled-granite.jpg]Dorrs Pond Dam Rebuild
Overview of dam reconstruction using recycled granite.

Five times in the past seven years rainfall in Manchester has been intense enough to cause water levels in Dorrs Pond in Livingston Park to rise above dam level, bringing flow crashing down onto the rocks below. Repeated overtopping can compromise the integrity of a dam by washing away soil necessary to its stability. As a result, the city has recently completed a project intended to fortify the area downstream of the dam to withstand overtopping at a rate more than twice that expected during a 100 year storm.
Leighton A White Inc. of Milford was contracted by the Parks, Recreation, and Cemetery Division of the Highway Department to install some 2500 sf of curbing on a concrete base to resist the forces of moving water. The $100,000 project was designed by TFM Inc. of Bedford. It was reviewed and approved by the NH State Dam Bureau and was funded through grants from the NHDES and the EPA. Dam specialists HTE Northeast Inc. provided inspection services.
Dorrs Pond Dam is classified as a high hazard dam by the state because people live immediately downstream and failure may result in loss of life. As a result, state requirements include the ability to withstand 2.5 times a 100 year storm. Rains corresponding with such a storm would result in water overtopping the dam by two feet; hence the use of robust granite curbstone pieces (minimum size of 3 feet x 1.5 feet x 6 inches). Physically the dam is made up of two walls, a 1.5 foot wide concrete wall along the pond side, and a stone masonry wall capped with concrete along the downstream side. The nine feet of space between them consists of compacted earth fill, and its length is approximately 125 feet. The dam passes pond flow via a 6.5 foot wide spillway, and it last saw work during a rehabilitation conducted in 1986.
Like the previous work, current tasks focused on minimizing erosion on the downstream side to prevent conditions that could lead to dam failure. In just over a month of work at the dam, the contractor removed two feet of soil, built the ground back up with compacted gravel, and placed approximately 200 pieces of used granite curbing on top creating an unerodable surface. The curbstones were laid on their side, and were grouted together with concrete. The spillway was doubly armored, first with two feet of 4000 psi concrete, and then with granite slabs. Granite was chosen not only for its hardness but because it was readily available, relatively inexpensive, and aesthetically pleasing.
In order to dig in the ground in the most favorable conditions Leighton White employed the use of four six-inch diameter siphons to lower the pond level to approximately three feet below the spillway. Siphons, depicted in Egyptian reliefs as far back as 1500 BC, use atmospheric pressure to pull water out of the pond, pass it over the dam, and discharge it below the worksite. The use of siphons was a perfect application on the project because once in operation they required no external power and ran 24 hours a day. Lowered pond levels made for easier and more stable excavation for the contractor. With the project complete, the Dorrs Pond Dam is fully compliant with NHDES regulations. Patrons of Livingston park, whether in the adjacent playground or out on the mile-long trail around the pond can admire the stonework for decades to come.

Featured article in “The Cabinet” about a demolition done by Leighton A. White, Inc.
A steam shovel ate away at the sprawling building on Nashua Street Tuesday morning as a worker from Leighton White Inc. hosed down the growing pile of debris.
The demolition of the house at 98 Nashua St. was good news to town officials who considered it a conspicuous eyesore at the gateway to downtown.
Dale White, president of Leighton A. White, said he only gives the best to his customers. In the case of his current workload, the best comes in the form of a Rototilt attachment, of which he has five.
A hydraulic attachment/tool, which can be used on most excavators and backhoes between 3 and 30 tons (2.7 and 27 t), Rototilt combines side tilt, rotation and a hydraulic quick coupler in one package, allowing a bucket or other attachment to be rotated and tilted at the same time. This makes it easier to operate around or under obstacles, and for any type of ground contouring.
“The Rototilt has the capabilities of doing from a $1,000 job to a million dollar job,” White said.
2008 was a milestone year for Leighton A. White, Inc. We celebrated 30 years in the business of providing exceptional construction quality, value, and timely work, underlined with the consistency of employee and customer safety. We have had another exemplary year with regards to our safety record, with no work-related injuries or illnesses. To further accentuate this landmark year, our product was delivered during one of the most disturbing economic years recently experienced in the United States.
During the past 30 years Leighton A. White, Inc. has focused resources on specialty and retrofit types of commercial, industrial, and municipal site work, plus athletic field construction and maintenance. Our clients include general contracting companies of varying sizes, engineering and architectural firms, manufacturing companies, and large-scale personal site work for home and business owners. In the communications field, our company provides road and tower site construction, drainage, and site maintenance during the harsh winters and heavy rainfalls prevalent in this clime. Job sizes range from $2,000 to $750,000, demonstrating the broad spectrum of situations we encounter. Our employees and jobs primarily cover the southern New Hampshire region, with frequent requests for services in the surrounding New England states. Due to typical cell tower locations, we often find ourselves working remote and rugged terrain, requiring special vigilance and expertise. Because of the varied and unique jobs we undertake, our employees have to be cognizant of multiple factors, including other tradesmen working on-site, civilian traffic levels in downtown areas, deep trenches, live utilities, and potential buried environmental hazards. We perform on tight sites where glass storefronts, existing buildings, and vehicles demand intricate care, and we have successfully completed our work under the utmost difficult weather conditions. As a licensed NHDES/Asbestos Disposal Site Contractor, our employees continually maintain certification which allows Leighton A. White, Inc. to continue its reputation for accepting the “impossible” jobs that no one else wishes to tackle, thus predisposing us to unusual and occasionally extreme work sites.

In 2008, Leighton A. White, Inc. faced some unusual work site circumstances. The New England area had experienced a crippling ice storm in the month of December. As the initial hours of immobility passed (i.e.: no functioning utilities), the requests to our company for emergency assistance began in earnest. We provided around-the-clock service to the cellular companies needing emergency access to remote, mountaintop sites. Heavy equipment and generators were desperately needed at the buildings at many locations all over Maine, New Hampshire, Massachusetts and Vermont. Due to the lack of regular landline telephone service, cellular use was all the more important and essential. Just getting to the work sites was very difficult, with power lines down across roads, and icy travel conditions. Our employees logged in 80-100 hour weeks while keeping vital technology, transport vehicles (i.e.: skidders, snowmobiles and ATV’s), and personnel safe in treacherous situations. One particular site required “visualizing” the transport of a large generator up an icy mountain and positioning it into a narrow spot prior to even beginning the job, allowing our employees to anticipate any safety issues and plan out their approach. During this ice storm event, our transport vehicles were continuously replenished with all anticipated tools and supplies necessary for known and unknown circumstances. Improvising was frequently necessary, yet vigilance with regard to safety remained paramount. It was no “accident” that we thankfully accomplished what was necessary without a single mishap on such short notice.
The single most critical element to the 2008 safety performance of Leighton A. White, Inc. could also be considered the most basic, fundamental concept. It incorporates common sense, known and accepted safety standards, daily verbal reminders to increase employee awareness of any potential hazards to themselves, to other tradesmen working alongside them, to buildings, and to underground construction. Simply put, our employees respect and practice the concept of “you can never be too safe”.
In 2008, our company continued our safety awareness practices and training, coupled with purchasing and implementing up-to-date equipment and technology, such as GPS instrumentation in many of our vehicles. This allows supervisors and owners to be in contact with employees, who in turn, have access to the safest, most efficient routes to remote and/or congested sites. The majority of the trucks in our work fleet are three years old and newer. The staff also has the benefit of an 8-hour Heart Saver CPR Certification Course and the 10-hour OSHA Safety Training Course in their safety portfolios. We also continuously strive to promote strict and safe equipment tie-down and moving procedures, utilizing hooks, straps, and fasteners. Our people have been involved in updating our full equipment list, thus making the tracking of maintenance easier and more thorough, as well as, adding to the overall safety in the workplace. It is obvious in interacting with our staff, that the daily reminders, the biweekly meetings, the specific classes, and the employee involvement in celebrating the receipt of safety awards all have a great impact on the minute-by-minute behavior of our people in the field. Frequently overheard by foremen and laborers as they go about their work is the phrase, “Safety first!”
Leighton A. White, Inc. is honored to once again be considered for this prestigious recognition, especially because it makes our 30th Anniversary Year all the more meaningful.
8/31/04 MISSION: IMPOSSIBLE
11/1/04 MISSION: ACCOMPLISHED
This was a job that could not have, should not have been possible. However the dedicated team at Leighton A. White, Inc. just simply made it work.
On August 26, the VP and director of athletics at Franklin Pierce College in Rindge, NH contacted Dale White; VP at Leighton A. White, Inc. He was requesting help in finishing an NCAA ball field, begun by another contractor. Dale, at first said it could not be done. Then upon seeing the desperate situation the college was in, he decided to evaluate the status of the project.
Upon first inspection the field looked like a war zone. It would be impossible to undo then redo the work in the fast narrowing timetable while maintaining their impeccable reputation for safety and superior work. However by August 30, after meetings with his project manager and company employees, they decided to take on the formidable project. The following day the college job site was in full gear.
Once started, the project became an even greater challenge. Two different sets of plans had been in use, material that was supposedly on-site was not, incorrect elevations, incorrect drainage, improperly backfilled pipe – the list of obstacles was endless. In addition to the seemingly insurmountable challenges, the artificial turf being used was imported from Sweden bringing its own set of difficulties. These included time zone changes, language barriers and no initial personal contact with the company. Added to the mix was a college campus filling with students for the fall semester, bringing foot traffic, parking difficulties, and fall sports.
On November 11, 2004 we looked at the completed project; clubhouse, bleacher pads, backstops, water, sewer, lights, press box, communication office and a beautiful field and knew that, against all odds, we had completed the impossible mission.
