‌ Vertical And Horizontal Transportation








Concept Design : At the concept design stage, we work with Architects to review the concept design brief, collect building population data, study the men/material movement within the building and prepare an estimate of average intervals and average waiting times. We establish and recommend design criteria based on international design standards and best practices and recommend the best suited elevator/escalator group configuration for each traffic type. We provide elevator/escalator/dumbwaiter core dimensions and indicate relevant structural support requirements. We provide a concept design report detailing our study, the design approach, the design criteria, traffic analysis results and the selected elevator group configuration. We also provide preliminary ideas on accessibility, firefighting elevator and service elevator.
 
Schematic Design : This is optional and applicable only if the concept design is completely changed. Activities are very similar to Concept Design. We attend design meetings, authority meetings and Client presentations as required.
 
Detailed Design : Based on the final elevator/escalator group configuration, we provide elaborate design details for the equipment, machinery spaces and control spaces. We define clearances, access conditions, structural load, mechanical coordination details, electrical coordination details, plumbing coordination details, interior design coordination details and carry out other specialty equipment/features coordination.
 
Tender Documents : We provide full length performance specifications in CSI format for the vertical transportation equipment [Sections 14210 and 14310]. Where necessary, we also provide specifications for ‘custom elevator cabs and entrances’. [14270.] We review the pre-qualifications of vendors and recommend the approved list of vendors, specific for the project. We also review pre-qualifications of elevator cab/entrance fit-out contractors, specific for the project.
 
We review if all the agreed design coordination and requirements are incorporated within the specifications. Alternatively, we can peer-review the specifications prepared by the Architects and provide comments for improvement. Where required, we review the vertical transportation design drawings prepared by the Architects for compliance with the elected vertical transportation design.
 
Main Tender Evaluation : We participate in the tendering process for the main works. We review and provide responses to the Tenderer’s queries related to vertical transportation promptly. Where required, we participate in the tender evaluation of main contractors and address issues related to vertical transportation.
 
Construction Documents : This is optional and applicable only if the tender specifications are completely changed at the time of awarding the main contract [due to value engineering or for any other reason].
 
Vertical Transportation Contractors’ Tender Review and Selection : We review and provide responses to the vertical transportation contractor’s queries promptly. We provide our technical assistance to review specific vertical transportation contractors’ technical and commercial bids. We thoroughly review the bids and provide deviation list and compliance requirements in comparison with the construction document specifications/drawings. We provide a technical comparison and a cost comparison of the elevator contractors. We conduct tender negotiation meetings with the vertical transportation contractors and make recommendations for timely award of the project and to achieve full/maximum compliance to the construction documents.
 
Construction Supervision : Once the Elevator Contract is awarded, we supervise the vertical transportation contractor’s complete scope of work to comply with the construction documents and agreements.
 
Desktop review of technical submittals and drawings : We review the technical submittals related to the elevator/escalator/dumbwaiter equipment [machine, controller, doors, fire & life safety equipment] and recommend their full compliance to construction specifications and governing equipment codes and accessibility standards. We also provide valuable inputs and recommendations for the interior decoration of the elevator cars and entrances, escalator truss cladding in coordination with the interior design Architect. We make coordination comments for the vertical transportation equipment with other engineering disciplines so that the vertical transportation systems work in tandem with other engineering features/equipment of the project. We also review quality control forms of installation data recorded on site, Operating & Maintenance Manuals, Warranty certificates and handover certificates.
On-site coordination meetings: We attend technical coordination and progress meetings arranged by the Architect on site. We review technical queries, construction difficulties and coordination issues at the meeting raised by the vertical transportation contractor and the main contractor. We provide technical guidance, we participate in site-walks with the construction supervision team on site and provide valuable inputs and clarify any query from the project’s Owners and stake holders.
 
On-site progress inspections : Upon specific request, we conduct progress installation inspections on site and review the status of installation of work and quality of installation. We inspect elevator entrances, inside of elevator shaft, elevator machine rooms, escalators, dumbwaiters and provide technical comments on deviations and provide guidance for improvement.
 
On-site material inspections : When required, we conduct material inspections on the materials destined/delivered for the project. We visit elevator/escalator contractor’s factories and/or interior decoration workshops; we review the material quality, specifications, test data and as-installed condition of the elevator equipment. We provide technical comments and recommend improvement of equipment quality and the interior finishes.
 
On-site performance inspections : At the time of handing over, we conduct performance specifications on fully completed elevators and escalators. We review the acceleration, jerk, door times and velocity profiles of each elevator and encourage conformance to original elevator traffic design. We verify the performance parameters, safety features and special functional controls against the construction specification and produce item-by-item specification compliance list. Deviations, if any, are highlighted and issued as a snags list. We carry out follow up inspections [when required] to verify if the previously noted snags have been cleared or not.
 
Modernization Consulting : We provide population surveys to assess waiting time/interval standards on existing buildings and provide recommendations to improve the performance of existing elevator/escalator systems. We survey existing equipment on for their condition and provide recommendations on expected life time, renewal/repair/replacement requirements, equipment upgrade to comply with latest equipment safety standards. Based on Client’s approval, we develop modernization tender specifications [both main equipment and interior finishes] conduct the modernization tendering process with pre-approved elevator contractors.
 
We provide our technical assistance to review specific elevator/escalator contractors’ technical and commercial bids. We thoroughly review the bids and provide deviation list and compliance requirements in comparison with the modernization specifications. We provide technical comparison and cost comparison and we conduct tender negotiation meetings with the Elevator/Escalator Contractors. We make final recommendations for timely award of the project and to achieve full/maximum compliance to the construction documents.
 
Construction Supervision : Once the Modernization Contract is awarded, we supervise the elevator contractor’s complete scope of work until completion to comply with the construction documents and agreements. Desk top reviews, onsite meetings and inspections are provided as deemed necessary.
 
Portfolio Management Consulting : For single building Owners and/or real estate companies, we provide technical assistance to manage their portfolio of vertical transportation equipment. We review the existing maintenance contract clauses, the qualifications of elevator maintenance companies and make recommendations on compliance to local regulation requirements with safe working conditions to the users and the elevator maintenance personnel. We survey existing equipment for their condition and provide recommendations on expected life time, renewal/repair/replacement requirements, equipment upgrade to comply with latest equipment safety standards.
