Surveying

The Company provides legal, topographic, hydrographic and construction layout surveys. Staff are equipped with current technologies for GPS surveys, electronic total stations, Civil3D software and Carlson survey software. Survey data can be provided to clients in drawing format or point data form as required.

CJMac have completed in excess of 2000 legal survey for boundary retracement of residences, commercial lots and woodlots. Boundary surveys have been completed for residential and industrial subdivisions, and water lots. Topographic surveys have been completed to support all types of engineering design such as: water and waster systems, building construction, storm water analysis, landfill rehabilitation, road design and natural gas distribution.

Project: Coalburn Wastewater

Coalburn Wastewater Extension Project
Municipality of the County of Pictou, Nova Scotia

C.J. MacLellan with ABL Environmental Consultants Inc. provided for design and contract administration engineering services for the construction of an extension to the existing collection system and upgrades to the existing sewage treatment plant.

CJMac acted as prime consultant responsible for structural, civil, and mechanical design. ABL provided the process design for the treatment plant and Nova Dynamics provided electrical and controls design. The project commenced in the fall of 2009 and construction commenced in the spring of 2010. Commissioning is anticipated by March 2011.

The design program was undertaken with a very aggressive schedule to meet funding requirements. The capacity of the existing treatment plant is to be expanded by 40% to 80,000 Igpd. The upgrades include additional aeration, a second RBC unit, a tertiary filter and improvements to the building envelope. The collection system extension was intended to service an additional 125 households with capacity for expansion.

The extension consists of: two new pumping stations and upgrade of an existing pumping station, 4,025 m of conventional gravity sewer, 2,125 m of small diameter gravity sewer, 1,525 m of low pressure forcemain, and 2,875 m of forcemain.

The project construction costs were tendered at $3.96 million with design and contract administration fees at fees at $ 333,000.

Project: Pomquet SBR

Pomquet SBR and Collection System
Municipality of the County of Antigonish -2002/2003

In 2002 C.J. MacLellan & Associates tendered over 4.5 kilometres of small diameter collection sewer (150mm diameter) and forcemain (75mm diameter) to service the Village of Pomquet. The project included individual pump chambers at those properties that required a pressure flow condition and cleanout chambers at others that flow by gravity to the local sewer.

One large lift station on Taylors road pumps sewage up to the treatment plant confluence manhole, while another on Cove road receives gravity flow than forces sewage back along the gravity line up to the confluence manhole near the treatment plant. An SBR treatment plant designed by ABL Environmental consists of one EQ tank, two reactors and a digester cell with the necessary

components to discharge effluent to the Pomquet harbour via a 450 metre long 150 mm diameter outfall pipe ballasted on the harbour bottom.

The project considered a number of tenders simultaneously with work extending over a one year period at a cost of $1.5 million.

Overall the Municipality is very pleased with the treatment plant and its connecting infrastructure and has on many occasions provided tours of the facility and system for municipal operators, NSEL staff and other interested parties in this technology.

Project: WWTP Biosolids Removal

Project: Antigonish WWTP Biosolids Removal
Client: Town of Antigonish

The Antigonish Sewage Treatment Plant sludge (1996 & 2005) had the initial stage which involved removing sludges from a twenty year old lagoon system prior to rehabilitation with a new raised wall six cell lagoon and a continuous sand filter. The new STP, after six years of operation, had a sludge quantity/quality test program undertaken jointly by ABL Environmental Consultants and C.J. MacLellan & Associates which recommended disposal by dewatering and biosolids composting at the Guysborough landfill.

A tender in late 2004 resulted in dredging and pumping the sludge biosolids through pre-screens, flocculation tank, and twin centrifuges for dewatering, with 220 bone dry tonnes hauling for composting and stabilization. C.J. MacLellan & Associates Inc provided contract administration, inspection. and sampling/testing services to the Town of Antigonish.

Project: St. Martha’s Hospital

Parking Lot Expansion, St. Martha’s Regional Hospital

C.J. MacLellan & Associates Inc. provided the engineering services for the construction of a new 60 space paved parking lot at St. Martha’s Regional Hospital.

Work included the legal survey to obtain the additional land required for the parking lot. Design and preparation of drawings and specifications. Tendering, Contract Administration and inspection services.

The project construction costs were $120,000. with design and contract administration fees of $20,000.

Project: Green Hill Estates

Killiam Properties – Green Hill Estates
Antigonish County – Nova Scotia

In 2006 C.J. MacLellan & Associates undertook a comprehensive grading exercise to develop an expansion area to an existing mini home park in Antigonish County.

This project, for Killiam Properties considered extensive earth moving in order to achieve desirable road grades in addition to suitable lot sections for proposed mini homes.

CJMac staff undertook a detailed topographic survey which led to the development of a detailed assessment of cut and fill balance in order to minimize earth moving costs.

Once grading tolerances were achieved detailed design of a road system with drainage to a two celled stormwater management facility ensued and the identification of full municipal services including asphalt road and curb system.
