3. INTRODUCTION

A specialized team from the Construction and Sustainable Buildings centre (CSBC) at the Royal Scientific Society made several visits to the mentioned site in the extended period from 29 June to 7 July 2020, as they conducted a careful visual inspection of the building and its surroundings. The team recorded the internal / external dimensions of the buildings in order to prepare as-built drawings that represent the reality of the building as much as possible by using modern surveying instruments (Total station and Level).

3.1. Existing geometrical documentation on the building

Architectural plans for the mentioned building were presented by Karak Municipality as AutoCAD file, Most of these documents that was provided by Karak municipality can be summarized as:

Basement Plan

Ground Floor Plan

First Floor Plan

General site map

All presented files weren’t completely accurate according to the visual inspection and the results of the survey work which is done by CSBC, so new architectural plans have been prepared for the mentioned building (as-built drawings) as possible and as circumstances permit.

All new prepared drawings are included in the annexes.

3.2. Type of survey adopted

In order to carry out suitable accuracy of the existing architectural survey, the adopted survey types by CSBC are through using modern survey instruments, mainly Laser Total station, Level, in order to prepare as-built drawings that represent the reality of the building as much as possible, besides using image-based survey (photogrammetry). This type of survey could also help the team to conceptualize and prepare accurate plans to represent the building, in addition of that, it is considered as the most suitable/ flexible method to deal with the privacy of the site and its precise details, especially due to the presence of narrow places and the presence of a mixture of old stone and new stone also the historical value of the building.

4. SITE CONDITIONS

The building was constructed in 1893 at Al-Karak city which lies about 140 km to the south of Amman on the ancient king’s highway. It is located in AL-Karak Governorate, specifically opposite the ancient Karak Castle, on an area of about (240) square meters (Picture 2 + Drawing 1). The building was constructed on two stages as the follow:

1- Stage No. 1 in 1893 (Othman Era):

The basement floor was constructed from true arches and vault made of limestone.

2- Stage No. 2 (from 1913-1926): The ground and first floors was constructed from true arches and vault made of limestone with steel/ I-Beams embedded in the slab supported by stone columns in the first floor.

The whole building was renovated several times, the first was in 1950, and the last time was in 2003.

The facades of the building are clad in old stone and new stone [Pic.s (1, 3 & 4)], the building is surrounded by a pavement from the front side (street side) containing some plant tubs, in addition to the presence of dirt portion from the back of the building [Pic. (4)]. in the eastern side of the building, there is a stair which leads into the basement [Pic.5]; the roof floor is isolated by asphalt rolls [Pic.s (1, 3 & 4)/ Drawing No.2]. The building is located in AL-Karak Governorate, in the area opposite to AL- Karak Castle. there is a public street from the front façade of the building with a tiled pavement for pedestrian [Pic.1], while there is a nearby building on both sides (western and eastern sides) of the building, and a dirt portion from the back side of the mentioned building, with a staircase leads to the basement in the eastern corridor of the building. There is a raised plant tub is connected to the building from the backside contains a big tree [Pic.4].

5. PRE PLANNING ACTIVITIES

5.1. Pre planning activities description

According to the correspondence between the National Energy Research Centre (NERC) and Construction and Sustainable Buildings Centre (CSBC) at Royal Scientific Society, The National Energy Research Centre (NERC) assigned “the Construction and Sustainable Buildings Centre (CSBC)’’ to provide a complete georeferenced geometric survey of the exterior and interior of the building by using the traditional-direct instrumental survey methods and photogrammetry, in order to obtain a complete representation of the building, ground and/or aerial scans (as-built drawings).

A specialized team from the Construction and Sustainable Buildings centre (CSBC) made several visits to the mentioned site in the extended period from 29 June to 7 July 2020, as they conducted a careful visual inspection of the building and its surroundings, and they recorded the internal / external dimensions of the buildings in order to prepare as-built drawings that represent the reality of the building as much as possible by using modern surveying instruments (Total station and Level).

Accordingly, drawings were prepared representing the reality of the mentioned building as much as possible, recording all observations in the building and its surroundings and including the results in this technical report.

5.2. Equipment

The Survey Instruments were used in survey works consists mainly of:

Laser Total Station (geo-FENNEL): - Provide efficient and easy solutions for setting out. - Three-dimension measurements of coordinates. - Visible laser pointer to improve targeting accuracy and allowing measurements

to be taken without looking through the telescope. - Measuring range of up to 200m in the reflector less mode.

Level: - Provide accurate levels and giving a general view of the Topography of the land

surrounding the building.

Cameras: - Using different type of cameras with clear\ proper resolution.

6.1. Description of the performed data acquisition activities

A specialized team from the Construction and Sustainable Buildings centre (CSBC) made several visits to the mentioned site in the extended period from 29 June to 7 July 2020, as they conducted a careful visual inspection of the building and its surroundings, and they recorded the internal / external dimensions of the buildings in order to prepare as-built drawings that represent the reality of the building as much as possible by using modern surveying instruments (Total station and Level).

6.2. Site Visits Results

6.2.1 Site Plan (Drawing 3)

The building is located in Karak Governorate, in the area opposite Karak Castle. And there is a public street from the front façade of the building with a tiled pavement for pedestrian [Pic.2], while there is a nearby building on both sides (western and eastern sides) of the building, and a dirt portion from the back side of the mentioned building, with a staircase leads to the basement in the eastern corridor of the building.

There is a raised plant tub is connected to the building from the back side contains a big tree [Pic.4].

7. POST PROCESSING

The following post-processing steps have been followed:

1. All data collected on the site moved to the office work stage, all the required data, which is done by Total Station, was downloaded to be prepared and equipped according to the followed work steps.

2. All the data of the topographic\ Levelling work have been collected and prepared to complete the office work on them according to the work steps.

3. Work on preparing the technical report that includes all the steps in cooperation between the field work team and the administrative supervision in the office

8. RESULTS

8.1. Survey Work results

Some necessary survey investigations (mainly Levelling) were conducted on the area surrounding the building [Pic. (29+30)]; the following are the most important results of the mentioned investigations:

– From the front side of the building, the levels drop towards the east in line with the decrease in the level of the opposite street naturally, without noticing any significant settlement.

– The level of the side lanes of the building decreases from the eastern side and the western side of the building towards the north/ backside of the building, taking into account the presence of external stairs from both sides.

– The levels of the backside of the aforementioned building/ dirt portion decrease towards the north / away from the building (The level of the natural earth).
