Importance of Point Cloud to BIM Modeling Services

Point Cloud to BIM modeling services make it possible for AEC surveying companies to base their designs on actual as-built dimensions and conditions of a site or structure, as contained in 3D models which have been digitally reconstructed from laser scan data. This ensures a high rate of success in designing for renovation or retrofit projects.

AEC surveying companies often struggle in renovation or retrofit projects lacking proper documentation. In culturally sensitive projects, quite often, missing or damaged structures need to be reconstructed and their signature architecture restored, without detailed plans to go by. Point cloud data obtained from laser scans and photogrammetry go a long way in bridging the information gap when the data is properly converted to 3D BIM models.

Survey firms employ technically proficient service providers to convert point cloud to Revit models. They help surveying companies detect the actual measurements of hard to reach or concealed structural elements

What is "Double Rodding" in Land Surveying?

Double rodding is a technique used in land surveying to ensure the accuracy of measurements taken with a leveling instrument, such as a level or transit. The process involves using two rods, one placed in the location where the measurement is being taken and another at a predetermined distance away.

Reasons Why the Public Should Not Attempt to Survey Their Own Land

This post isn't really for our members as much as it is for the public- those looking to "Survey my own land." This post can be shared outside of the surveying community as a plea to understand that it is never a good idea to attempt to survey one's own land. If you are a member, add your comments below and share this so that we might be able to collectively educate those outside of our circle.

BEING THE SURVEYOR OF AN AIRFORCE BASE DURING THE 1980’s

BEING THE SURVEYOR OF AN AIRFORCE BASE DURING THE 1980’s

Introduction

The South African Defence Force, now the South African National Defence Force (SANDF), was involved in a Bosoorlog or Grens oorlog (Bush war or Border war)¹ from 1966 till 1989.

In order to protect the most northern borders of South Africa, a number of smaller, shorter perhaps, airstrips or airfields, sometimes referred to as tactical airfields, were constructed or in some cases upgraded.

Examples of the above are Ellisras, Punda Maria (in the Kruger National Park) and then a full scale air force base with a 4000 m runway at Louis Trichardt.

The construction at Louis Trichardt was given the project name Braambos.

A Little Bit of Background

I joined the South African Airforce during June 1972. My initial mustering was Construction Machine Operator and I was deployed at 402 Airfield Maintenance Unit (402AMU) with head quarters at air force base Ysterplaat in Cape Town. I completed the training course on 11 February 197

CURIOUS STATIC DATASETS

I have been using VRS for project location for some years. I need to set up a control network for the Highway Department using a static network. I dug out the old Ashstech Extremes to set up the network. When I downloaded the files, both the almanac and datasets were dated 02.107 instead of 21.333. I was always under the impression that the receivers got their time stamp from the GPS signals.

Why is Land Surveying Beneficial?

Land surveyors use special instruments and techniques to measure the boundaries of a piece of land. They use this information to create a detailed map of the property, which is used to plan out developments or create legal documents. It is also used to make sure the boundaries of a property are clearly identified.

How BIM can affect Quantity Surveyors?

BIM automates core processes for quantity surveyors in the preconstruction stage by reinforcing the 3D BIM model with material and component cost estimates, model-based BOMs, and scheduling.

THE GREAT DIAMOND HOAX OF 1872 - UPENDED - Part III

We are sorry to skewer the sacred surveyor, Clarence King, (maybe we should call it the King shish kabob) but his Great Diamond Hoax of 1872 was not a hoax. Modern science has determined that John Slack's and Phillip Arnold's Diamond Peak and Diamond Flat are in diamondiferous areas, along with other nearby areas in Colorado and Wyoming. Clarence King was the hoax, and the only surveyor in history to start his own bank. How did he get that money?

The Great Diamond Hoax of 1872 - Upended - Part II

The misuse of men of science, by industrial and political leaders, has a long and sordid history. Such misuse happened in the diamond fields of Brazil, South Africa and Colorado/Wyoming. A South African whopper told in 1868 by one Geologist J.R. Gregory led to the labeling of such blatant whoppers as "telling a Gregory". Can there be the telling of "a Clarence King" or perhaps a "Fuchi"?

The Great Diamond Hoax of 1872 - Upended - Part 1

At the 2020 Tucson Gem Show we approached Clint and Louisa Cross and asked them what they knew about the Great Diamond Hoax of 1872, that hoax uncovered by USGS surveyor #1, Clarence King. Clint Cross is from the Missisquoi band of the Abenaki Nation and the owner of North Star Turquoise out of Cripple Creek Colorado. Since that hoax happened at the Colorado/Wyoming boarder and as their's was the only Colorado or Wyoming booth that we found among the 4000+ Tucson booths, they seemed to be just the ones to ask. However, Clint's immediate and unflinching response drove us to our knees: “That wasn’t a hoax”!
