A survey assignment’s complexity depends on the type of surveys needed, the time required to complete the field work, and the office time it takes to process the data and generate maps and plans. It’s not uncommon on large projects to utilize several different land surveying teams.
When the job calls for more than one survey team, the land surveyor’s primary intent is to efficiently collect all necessary data. The challenge, however, is to effectively plan, coordinate, and manage these teams in such a way to avoid mis communications and task redundancy, overlap, and need to re-survey. This post provides a number of construction project planning tips in order to help managers seamlessly oversee these multiple teams.
Managing Multiple Land Survey Teams
Land surveying firms offer a variety of services. For any major project there is a need for:
- Pre-construction planning
- Amendments and changes
Within any project phase there are needs to simultaneously provide layout, staking and control services:
- Permits– Accesses, drainage and pipeline crossings, river and stream diversions, relocations.
- Environment Concerns– Pre-construction and construction delineation and mitigation.
- Site Design / Earthwork – Boundary lines and plats, well pads, staging, building, production.
- Layout And Control – Grade, pipe and pipeline bridges, structure and equipment foundations
- Geotech Data – Borrow sites, volume calculations, bearing capacity, slope stability
- Post Construction – As-builts, claims.
Criteria for Survey Team Management
Utilization of the latest land surveying technologies and current software is important to efficiency. Land surveyor teams with better tools are more flexible, mobile, and scalable. The land surveying manager then is not as concerned with equipment reliability, availability, and accuracy, and can focus on deploying teams that can fully execute their assignment in a timely manner.
There are three basic things that can be done in order to effectively coordinate multiple survey teams and help ensure survey assignments are completed on time and within budget:
1. Utilize Land Surveyors Experienced In Working Together And/or Familiar With The Particular Region.
When teams have experience working together, there is usually better communication. This communication is especially helpful if at least one of the teams has experience working in the region that is being surveyed, as they can provide better insight into how to go about the survey.
Land surveying teams are comprised of a party chief/lead, and technicians knowledgeable in the specialty (utility, right of way, seismic, geotechnical, and environmental, boundaries) that the particular assignment requires. Familiarity with the region, landmarks, markers, and unique obstacles such as streams, rivers, rugged terrain and total open space help reduce the potential for unpreparedness and unnecessary complications. These issues can include un-calibrated equipment, poor field organization, slow decision making and problem solving delays. It is also not uncommon to find a survey team lost enroute to a remote jobsite. When at least one team is experienced working in a particular region, they are able to communicate and wok through the challenges.
2. Establish Criteria for Plats at the Start of a Project
Preliminary plats are used as a starting point for most projects. They are considered comprehensive tools and may be changed during the course of the project. They should contain significant information to lay out the proposed project. Plat maps should show:
- As-built geological data and legal descriptions
- Identified boundaries, floodplains, drainage courses, road accesses, easement, right of way
- Past and proposed site development
- Underground as well as above-ground structures
- Ownership, occupancy, legal rights, third-party rights, claims, and liens
However, different surveying teams may use different criteria for each of the plats that they create. This can create confusion and miscommunication when information needs to be compared between plats from two different teams. If you are bringing in multiple survey teams, make sure to establish the criteria for the plats early on to prevent this confusion.
3. Utilize a Project Management System
A project management system is invaluable to construction project planning. A project management system allows different survey teams to easily share information on a single platform and collaborate effectively with the client. This improves communication between teams and creates a single depository of information for them to put upload data to. This greatly increases the speed from which the multiple teams work and makes it less likely to have discrepancies between data collected between the two different teams.
