Established in 1984 as a specialist project and construction surveying company in the Upper North Island region, WalkerSEP has grown from a background of land title/cadastral and engineering surveying for provincial consultants based in the Wanganui/Taranaki/Central North Island region in the 1970s/early 1980s. These included project works on the ski fields of Mt. Ruapehu followed by open-cast mining, marine and gas pipeline construction planning and setting out surveys.

WalkerSEP's involvement in one of New Zealand's think big energy projects, New Zealand Steel at Glenbrook (south of Auckland) during the mid-1980s signaled the beginning of the company's role in providing a specialised surveying service to large-scale industrial, high-rise, airport and civil construction projects, which involved WalkerSEP with many of New Zealand's largest construction projects in the last three decades.

(Details of major projects WalkerSEP has undertaken are shown here.)

Some benchmark projects include 18 years of expansions/projects at Auckland International Airport, as well as new terminal building contracts; roading and airport projects in Pacific Island territories including American Samoa, the Marshall islands and Tonga; heavy industrial projects at New Zealand Steel (Glenbrook), Southdown and Te Rapa Co generation Power Stations, America's Cup 2000 Viaduct Harbour basin development, the interesting geometry of the Aotea Centre and the TVNZ Network Centre, Sky City Casino (Auckland), ANZ Tower and Metropolis projects, and the Botany Town and Sylvia Park shopping centres.

WalkerSEP has grown with a client base comprising most of New Zealand's largest construction companies (Hawkins, Multiplex, Fletcher, Mainzeal, etc.), organizations (Auckland International Airport Ltd.), and design architecture/engineering consultants on a long standing relationship basis extending in many cases over three decades. WalkerSEP stay engaged for the duration of the contract, from the initial pre-construction planning phase, through to the piling/foundation and main cyclical/structural construction, and often also in the finishing works, final certification and as-built mapping stages, working with clients, contractors and design consultants alike as part of the teamwork approach required for the successful completion of the project.

The company's solid grounding in large-scale projects has been the result of a proven track record of providing an accurate (often to plus or minus 1mm) and reliable surveying service in accordance with the critical path programming timetable and budget constraints typical of these works. Accordingly, a long standing company philosophy is to position the assigned field survey teams at the work face, operating on less than one day's notice (if not on site full time) and reacting immediately to a contractor's needs if at all possible, often on a 24 hours a day/7 days a week basis where required. The benefits are include increased construction productivity from such construction tradesmen as machine operators, carpenters, concrete placers, boilermakers, riggers, piling constructors, and more.

While this work involves standard surveying work, measuring and setting out specific construction positions and as-built mapping at pre- and post-construction phases to complement project planning and design purposes, the company has vast experience at working at heights, enclosed spaces, high security and safety zones (motorways, international airport runways, etc.), with many projects adding extra geometrical shape challenges. WalkerSEP has worked at times in conditions of considerable physical demands involving noise, weather, temperature, time deadline, aircraft operation and darkness challenges.

All staff are construction experienced and site safe accredited.

WalkerSEP have qualified civil engineers and planners working on a variety of projects ranging from local authority drainage upgrades to large land development projects. Working in partnership with our planners and surveyors, WalkerSEP can take projects from concepts through design and resource consent to construction and completion. Our land transfer surveyors complete all title work necessarily for the land development projects to obtain titles as quickly as possible.

Some of the projects our engineering team are involved with include Matarangi Beach Estates, Spinnaker Bay, Pine Harbour Marina, Flat Bush Storm water detention Pond DIA.

The company now employs over 40 full-time staff members with up to 12 survey teams in the field at any one time, each equipped with the leading edge technology equipment, including electronic reflector less total station laser and Bluetooth GPS technology. Engineers and Surveyors are registered, graduate and technician qualified via Unitec/University, with experience in all types of engineering surveying with the strong emphasis obviously on civil, high-rise, airport and heavy industrial surveying.

The combination of the company's high standards, experience and meticulous checking procedures makes WalkerSEP a team you can trust to deliver your engineering, planning and construction/project surveying works reliably, accurately, and on time.
