Sunshine Marina Ltd
OPERATIONAL REQUIREMENT FOR A
WIRELESS LOCAL AREA NETWORK
1.1. Background to this Operational Requirement
Sunshine Marina Ltd (SML) is an established company who are in the process of updating their facilities and require to provide basic Wi-Fi connectivity for their customers. There is no current wireless system and no direct interference for existing systems.
The WLAN components and infrastructure should adhere to national and international (wireless communications) standards.
The purpose of this exercise is to select a supplier from whom the WLAN products and services may be purchased.
1.2. Objectives for this procurement
At a broad level, the purpose of this exercise is to provide flexible wireless connectivity throughout the SML.
The WLAN should be upgradeable to cater for more users, wider geographical coverage, higher traffic loads and developing technology. The WLAN should also be resilient, secure and cost effective. Appropriate management and support facilities will also be required.
1.3. Purpose of this document
The responses to this document will be used to determine a shortlist of suppliers who can meet the stated requirements. The suppliers may then proceed with discussions, and if appropriate formal tenders will then be invited.
The responses to this document will be assessed against the viability of the technical design, and also the professionalism of the supplier’s ability to fulfil the tasks of installation, training, project management and post installation support. Responses must be presented in the format outlined later in this document.
2. SCOPE AND SCALE OF THIS PROCUREMENT
SML intends procuring a complete WLAN infrastructure service including:
• Installation of access points including cabling and equipment correctly configured to support them. This excludes components considered part of end user systems for example WLAN cards and PCs but including components such as servers and equipment for managing and protecting the network-infrastructure such as Firewalls, Proxy-Systems, Routers, Gateways and Network-Management-HW.
• A network management system
• Training and documentation
• Post installation support and maintenance
SML reserves the right to insist on alternative components, if they are considered to be functionally equivalent, better, or more cost effective.
SML requires the whole network to have a high level of security for both the wireless and cabled elements.
3. Sunshine Marina Ltd
A scale plan of SML’s marina is shown in appendix A. The plan shows an office building of single story reinforced concrete construction. The building has been designed such that in the future a second story can be added.
1. All customers must be able to connect to the network from anywhere within the marina or office building with at least 2 Mbps throughput rate. System must support all types of customers WiFi devices.
2. All computers should be networked so that internal and external Email can be supported.
3. Internet Access must be provided to ALL staff.
4. A fileserver should be provided, within the office building.
5. Internet connection is provided within the office building.
6. There are currently 4 desktop computers situated within the building that will need to be networked.
7. A comprehensive network management solution needs to be sourced.
8. Note the environment is salt water based so appropriate equipment needs to be sourced.
9. Customers will provide their own devices so the system needs to be able to connect with both old and new devices.
4. USE OF STANDARDS AND MEDIA INSTALLATION PRACTICE
4.1. Standards Compliance
The network must comply with all current installation and wireless standards.
4.2. Media and equipment installation
All surface mounted media MUST be housed in suitable trunking.
Suppliers MUST give assurances that the media they intend to use will meet, when installed and connected to working equipment, the current and anticipated national and European standards for safety, fire resistance and electro-magnetic interference.
Media and other hardware installation MUST also make proper allowance for the environment in which it is installed, particularly as regards:
• received levels of electro-magnetic radiation;
• possible variations in electrical Earth potential at different points around the site.
The selected supplier will be given the opportunity to survey the environment in which the equipment is to be installed.
The supplier is REQUIRED to state what installation standards or code of practice(s) will be adopted.
5. QUALITY OF SERVICE REQUIREMENTS
This presumes a 24 hour per day, 7 day per week service.
Time between fault incidents of greater than 8000 hours.
5.2. Fault Repair Procedures
Suppliers are REQUIRED to state what level of warranty is included in the price of the equipment? Please specify:
a) The length of warranty on each component of the proposed network;
b) The terms of the warranty including any violations which may be invoked should SML add, modify or replace parts of the network;
c) Any additional costs which SML may incur in obtaining warranty support. For example: if the warranty covers only parts and labour.
d) Callout and Fault Removal
A callout service appropriate to the serviceability requirements of section 5.1, MUST be provided for the remedying of software faults and hardware faults, either by repair or replacement.
Fault Escalation Procedure
A fault escalation procedure involving senior management and senior technical staff MUST be available if faults are not rectified within agreed timescales. The supplier is to suggest values for these timescales for mutual agreement with SML.
Installation covers the period from the selection of a supplier to the formal handover of the WLAN and LAN infrastructure to SML. This includes supply and physical installation of access points, cables, hardware and software. The selection and training of user staff will not be the responsibility of the supplier.
6.2. Project management
An installation plan must be provided which includes the length of time required for each part of the installation.
Regular meetings must be held between a named manager from the supplier and SML staff during the installation phase to discuss progress and problems.
6.3. Project plan
This section introduces the Project Plan. Initial start date and responsibilities allocated between SML and the supplier.
Allocation of Responsibilities
The supplier must take responsibility for satisfactory provision of:
a) network design;
b) supply of hardware and software;
c) physical installation of hardware and software;
d) technical documentation;
e) technical staff training.
The following subsections describe the overall management responsibilities that need to be agreed where relevant.
SML will provide an office for the supplier to use during the installation phase and reasonable access to other personnel for the clarification and resolution of queries that may arise.
The supplier is asked to state what office accommodation and other services will be required for this phase.
A detailed project plan produced in Microsoft Project is required. This must show a breakdown of the major tasks expected during the project. Actual installation will begin week beginning the 13th May 2014.
