1 Additional Guidelines for Structural Requirements (i) (ii) (iii) (iv) (v) (vi) (vii) (viii) The Tenant s contractor shall ensure that no structural integrity and components are affected. If any structural components are affected, the contractor shall stop work and inform the Landlord. The Tenant s contractor has to make good and rectify any damages at its own cost. No hacking is allowed on the building structure for the laying of building services. However, a maximum hacking depth of 25mm is allowed through the finishes provided that the structure beneath the finishes is not damaged. No hacking/drilling is permitted on pre-stressed structure, joints and waterproofed membranes. The Tenant s contractor's Structural/Civil PE is to certify that the works will not affect the structural integrity when it is required to hack or drill through the floor or ceiling slabs for installation of partitions/false ceilings, etc. All imposed loads on the floors of the Passenger Terminal Building shall not exceed the maximum safe weight load of 5 KN/m2. The Tenant shall inform the Landlord once work has been completed. IMPORTANT: If the premise given to the Tenant is an open empty space, Tenant must adopt an open concept design for this outlet to allow maximum flow-through and visibility without any closures (unless approved exemption from CAG is received). In addition, the Tenant shall ensure that the boundary of the Premises shall not be built-up, with for example, back walls/partitions/glass, to preserve the transparency as well as the visibility of the surrounding retail concessions.

2 GENERAL GUIDELINES FOR STRUCTURAL INSTALLATION ITEM GUIDELINES / REQUIREMENTS 1. Knocking down of Load bearing walls and partitions cannot be removed unless the loads carried walls / partitions of adjoining floor areas are fully transferred to other parts of the structure without effecting the structural integrity, stability and strength. Such proposal shall be designed by Structural / Civil P.E* & subject to the relevant authorities approval. Any demolition works shall be done in accordance to SS557:2010 Code of Practice for Demolition. 2. Additional Load / Installation Details of ** Permanent additional loads ( e.g racking systems, safes, weighing machines, additional ducts, services, projectors, etc) proposed to be placed onto the floor area or structural members must be submitted to CAG(S) for approval. Prior to submission, the Successful Tenderer is to ensure that the proposed loads / installation for that floor or structural member does not exceed its design live load+ and this should be verified by the Successful Tenderer s Structural / Civil P.E s. * Sub-note: Steel plate spreaders are to be provided to evenly distribute the load onto the structure where high concentration of point-loads is anticipated. The spreader is to be designed by the Successful Tenderer s Structural / Civil P.E *, steel plate spreader designs must not impose too much of its self-weight onto the existing structure. 2.1 Change of use Any change of use for the area must be made known to CAG(S). 3. Hacking of floor / coring / Walls/ columns or ceiling No hacking or coring is allowed on the structural members for the laying of building services. However, a maximum trimming depth of 25mm is allowed through finishes provided the structure beneath the finishes is not damaged. Groove lines should be cut to prevent over spalling of adjacent concrete along the line of trimming. Any trimmed areas are to be patched back using nonshrink grout. Beams and webs of hollow core slabs shall be avoided during coring. Coring on Pre- Stressed beams should be carried out only upon further inspection and certification by a PE. Fibre wrap materials used for slab/beam/column strengthening & waterproofing membrane used for RC flat roof /planter box area shall not be disturbed/affected. Sub Note: For any openings at fire rated wall due to their services penetrations, contractors are to seal off with Approved fire materials and endorsed by the fire PE 4. Erection of partitions / false ceilings The following should be submitted for approval : a) Specifications of proposed partitions / false ceiling b) Drawings to show the proposed locations of partitions/false ceiling c) Details of the methods of installation of partitions / false ceiling d) PE calculations to design to Code of Practice for Dead and Imposed Loads BS6399: Part 1 for lateral/impact loads onto partitions The Successful Tenderer s Structural / Civil P.E is to certify that the work will not affect the structural integrity when it is required to carry out hacking / drilling on structure members. (Supervising PE must made known of areas of Post Tension Beams, Prestressed Planks/Tee-beams and Precast Prestressed Precast Beams (PSPC) under its care)

3 * Structural / Civil P.E to certify statements / calculations / necessary documents to state that renovations work / other works do not affect the structural integrity. * Carry out pre-con dilapidation survey (Pre-con survey) if renovation works involving hacking/demolition of structure. * Provide instrumentation plan for our approval (demolition/hacking): - Noise Meter - Settlement Markers (Building/Ground) - Vibration Meter * Impact assessment report to be submitted for our record (For hacking/demolition works only) ** Permanent additional loads refer to under hanging as well as top resting loads. + Refer to Annex A for Loading Criteria

5 Common Renovation Queries Civil Loading Queries of Terminal Buildings Knocking down/removal of partition Any installation which requires Hacking/Coring/Dr illing of walls, floors Drawings doesn t correspond to the site Hanging Loads to Ceiling PE Calculations & Endorsement Submit to Civil for Assessment Any Installation which imposes load to the building Floor Loading of Terminal Buildings General Floor Loading Plan/Floor loading Criteria Load-Bearing Wall Arrange for a Site Inspection PE to study the wall on-site and endorse PE to carry out precon survey & provide instrumentation plan and impact assessment report Non load bearing/nonstructural wall Can be removed Should not reach the rebar s (only 25mm through finishes allowed) Structural Members cannot be altered. Existing fibrewrap & waterproofing membrane shall not be affected. Division to gather info for any A&A works in that area Tenants should provide the drawings for A&A works
