The Department of Construction and Projects has undertaken a comprehensive rehabilitation process for the external walkways of the Technological University Presidency building. The executed works included several steps aimed at improving and renewing the walkways, and the tasks were detailed as follows:

• The team removed the old granite flooring from the walkways around the Presidency and cleared the debris.
• Demolition work was carried out for the flowerbeds in the external walkways of the Presidency, with debris removed from the university premises.
• Concrete flooring was poured in the walkway leading to the Presidency's entrance and the corridor opposite the incoming and outgoing rooms, using resistant concrete, sand, and crushed gravel with reinforcement through expansion joints.
• The team used cement and sand to apply new granite to the flooring in front of the information desk entrance, the side door, and the side ramp.
• Flowerbeds in the walkways were designed and poured using reinforced concrete and rebar, with the inner surface polished using plywood.
• Layers of granite and rounded porcelain were applied to the surface, finished with a marble-specific material.
• Flowerbed walls were painted with moisture-resistant epoxy paint, and granite mirrors were applied using a particular substance.
• Ground lighting brackets were installed with lighting fixtures connected to a control panel, and power outlets were installed with plastic pipes.
• Marble and cobblestone pieces were installed on external walls and around the walkways using adhesive materials and cementitious seam filler.
• Expansion joints for the walkways around the Presidency were filled using polysulfide material.
• The metal tank was removed, and a plastic water tank was prepared, installed, and connected with accessories.

These works were carried out according to technical standards and specifications, and the relevant committee approved the results. Daily site cleaning was ensured during the work period, with no work residues left for the next day.

The Construction and Projects Department has conducted comprehensive rehabilitation works on the flooring and garage of the main building in the Oil and Gas Engineering Department. The steps by which the work was carried out are detailed as follows:

• External cooling device components were lifted and repositioned in their original locations after completing the works.
• Furniture and damaged materials behind the department's building were temporarily removed to facilitate the works and were later returned and arranged appropriately upon completion.
• The external walkway flooring of the main building was removed and lifted.
• The garage floor of the Oil and Gas Engineering Department was removed and lifted.
• Preparation, leveling, and adjustment of the sub-base layer was performed using a site leveler.
• Concrete was poured using salt-resistant cement, sand, and gravel, using SBR material for bonding with the existing concrete.
• According to the plans, Full-body porcelain tiles were applied to the front external walkway flooring using weather-resistant adhesive.
• Pieces of kerbstones were installed and secured.
• A layer of nylon was laid, and stamped concrete was poured.
• The sewer network was rehabilitated by changing its routes and placing new manholes with covers to improve drainage efficiency.
• Daily site cleaning was maintained, ensuring no leftover debris for the following day.

The rehabilitation works were executed with high quality, significantly enhancing the overall environment around the main building of the Oil and Gas Engineering Department.

The Construction and Projects Department has constructed an emergency staircase in the Oil and Gas Engineering Department. The project was carried out following these steps:

• The team excavated the ground in the adjacent side corridor of the building.
• Damages resulting from the excavation process were addressed.
• The old sewage pipes and manholes were lifted under the stair foundations.
• A new drainage network was established, connecting to the existing network.
• Plastic manhole molds connected to the drainage network were installed and secured.
• Walls below windows were demolished to create openings for emergency doors on each building floor.
• Damaged walls from the interior and exterior were repaired based on demolition-related damages.
• A layer of sub-base was laid with proper leveling.
• Foundations for the emergency stairs were poured with reinforced concrete using resistant cement, sand, and gravel, with reinforcement according to the plans.
• An iron door was installed on the emergency staircase on each building floor.
• The emergency staircase was constructed using iron sections outlined in the plans.
• LED emergency exit lighting with directional indicators was installed on the ceiling and walls on each building floor. The lighting includes a charger and battery that operates for at least three hours.
• Daily site cleaning was ensured during construction, with no leftover debris for the next day.

These activities were carried out following engineering standards and with high quality, ensuring the safety and security of students and staff in emergencies.

The Department of Construction and Projects has successfully executed a comprehensive rehabilitation process for the Communication Engineering garage. The following steps were undertaken:

• The garage floor was dismantled and removed until the damaged sewage pipes were reached.
• The laying, connection, and installation of heavy sewer pipes were carried out using plastic pipes with all attachments, and the process also included connecting them to manholes.
• The old manhole and its frame were removed, and a new plastic manhole cover was installed.

• The sub-base layer's preparation, leveling, and adjustment were accomplished using a site leveler.

•  

   A nylon layer was laid, followed by pouring reinforced stamped concrete using ready-mix concrete and welded wire mesh (BRC), using SBR material, and creating joints using cork.

• Pieces of kerbstones were installed with paint.
• Daily site cleaning was ensured during the work period, with no work residues left for the next day.

These tasks were carried out with high professionalism and per technical specifications, ensuring the quality and durability of the structure at every step.
