ILORIN INTERNATIONAL CONFERENCE CENTRE, (IICC) ILORIN. 1 PROJECT TITLE: INTERNATIONAL CONFERENCE CENTRE, ILORIN ARCHITECTURAL DRAWING: OBSERVATIONS 1. Some of the rooms are not labelled for ease of determining the Illumination requirement and usage; 2. Service ducts are required to be provided to allow for seamless installation of varying sizes of pipes and maintenance; 3. Floor plan of the Gate House which is assumed will be located by the gate is not provided; 2 PROJECT TITLE: INTERNATIONAL CONFERENCE CENTRE, ILORIN ELECTRICAL DRAWING OBSERVATIONS 1. The incoming voltage level from the supply Authority is 11kv and not 33kv. This implies that the required transformer shall be 1500kva, 11/0.415kv and not 1500kva, 33/0.415kv; 2. External Lighting lay-out not detailed to standard specifications. The 2No. 12-ways 100A TP&N Distribution boards proposed for the supply of Power to the external light is in appropriate for effective performance of the installation; 3. There should be a separate drawing for External Cable layout that will indicate cable route from the Generator/Power House to other ancillary unit within the premises. With this arrangement there shall be main Distribution Panel located at the Generator House and Sub Distribution Panels as may be required; 4. The Distribution panel tagged drawing EDI is not detailed enough to carry the total load of the main building. 15No. Lift cars, Fire pump are completely omitted; 3 5. Distribution Board DBOA, DBOB, DBOC & DB-M1 are designed for Basement Floor. Actual Location of the 4Nos. Distribution Boards are not indicated. It is also professionally in order to have a Sub-Distribution Panel at the Basement Floor to replace DB-M1 because all the Air-conditioning Unit connected to DB-M1 are 3- Ø by design; 6. Distribution Boards DB1A, DB1B and 8-way, 200A TP&MCCB Distribution are designed for Ground Floor. Actual location of the 3Nos. distribution Boards are not indicated on the ground floor. It is professionally in order to have a sub-distribution panel at the Ground Floor to replace the 8-way, 200A TP7N MCCB Distribution Board because all the Air-Conditioning Unit connected to the Distribution Board are 3-Ø by design; 7. Ditto as above for all the Distribution Boards for as follows; (a) DB2A, DB2B, DB2C, DB2D and 8-way 100ATP&N MCCB Distribution Board – Air conditioning load Distribution (First Floor); (b) DB3A, DB3B, DB3C, DB3D and 8-way 100A TP&N MCCB Distribution Board – Air conditioning load Distribution (Second Floor); (c) DB4A, DB4B, DB4C, DB4D and 8-way 100A TP&N MCCB Distribution Board – Air conditioning load Distribution (Third Floor); (d) DB5A, DB5B, DB5C, DB5D and 8-ways 100A TP&N MCCB Distribution Board – Air conditioning load Distribution (Forth Floor); 4 (e) DB6A, DB6B, DB6C, DB6D and 8-ways 100A TP&N MCCB Distribution Board – Air conditioning load Distribution (Fifth Floor) 8. The load cables recommended for all the Air conditioning load Distribution did not take into cognizance of the starting current of all the 3-Ø Air Conditioning Units recommended; 9. There is the need to check and confirm the Number of fittings considering the lamp specification without proper reference to Manufacturer’s catalogue; 10. So many fittings are observed to be concentrated on a sub-circuit for no reason. Sub circuit re-distribution in this case is necessary for a balance load distribution system; 11. The Number of Smoke Detectors is a function of the area of a Particular room. There is the need to review the number specified in compliance with standard regulatory Body; 12. All the Fire Alarm initiating call point, Smoke Detectors and Sounders are not classified to know which zones they are connected to as recommended by standard practice. Thus making it extremely difficult to know how many Zones of Fire Alarm to be installed; 13. The type of Fire Alarm Distribution panel is not indicated on the legend neither the location on the drawings. This is quite necessary for ease of piping and monitoring; 14. A detailed schematic diagram of fire alarm installation is necessary which is not included on the drawing; 5 15. The closed circuit Television system is not detailed enough on the drawing forwarded. It is quite important to specify the type of CCTV system that is recommended, whether Analogue or Internet Protocol (IP) System. The position of the CCTV Visual Display Unit not indicated. It will be difficult to interpret the drawing provided particularly at the stage of first fixing by the contactor; 16. Detailed line schematic diagram showing the position of VDU, PTZ joystick NVR, Video Switchers and IP Camera is required for ease of cabling; 17. Access control system(ACS) are equally not detailed on the drawings. It is not indicated the type of access control to be deployed and the location of all the control panels; 18. IP Television Layout not detailed on the drawing for ease of piping and installation; 19. There is the need for detailed Data/voice design which is very important in an International Hotel for ease of Communication. The existing drawing only indicated location of Telephone/Data point and Wi-Fi without detailed connection and schematic layout; 20. Public Address System(PAS) not indicated on the drawing which is necessary. 6 GENERAL REMARKS ON ELECTRICAL DRAWINGS The drawings forwarded can be considered to be 60% completed and there is the need to fix all the above discrepancies in order to make it a complete working drawing. 7 PROJECT TITLE: INTERNATIONAL CONFERENCE CENTRE, ILORIN MECHANICAL DRAWING The following are required to be added to Mechanical drawings for a complete working drawing: 1. Fire hydrant at different location on the external site layout is required; 2. External drainage system is necessary; 3. External cold water layout indicating the following: (a) Raw water storage tank (b) Water treatment plant (c) Potable water storage tank (d)Booster pump and (e) Elevated water tank 4. All pipes shall be PVC dignity or approved equivalent. No galvanized pipe is Permissible; 5. Fire hydrant, shall be connected to fire pump, whose location shall be by the Gate or appropriate position on the site. 6. All toilets are required to be provided with inlet fan which are completely omitted in the Mechanical Drawing forwarded; 7. All drain pipes from Air conditioning Unit shall be property discharged to the main drains 8. A dedicated tank is necessary for the Fire Hydrant, Fire Hose Real and Water Sprinkler. 8 GENERAL REMARKS ON MECHANICAL DRAWINGS The drawings forward can be considered to be 60% completed and there is the need to carry out all necessary amendment as observed to make the drawing a complete working drawing. 9 17th November, 2021 The Managing Director, EDIL Management & Consultants, No.11A Asa Road, Ilorin. RE: ILORIN INTERNATIONAL CONFERENCE CENTRE: OBSERVATIONS ON THE ELECTRICAL & MECHANICAL DRAWINGS Please find attached our observations on the Electrical & Mechanical Drawings in respect of Ilorin International Conference Centre for necessary amendment. 2.
